Dell Laptop Laggy With Jaws On Battery Power

Tom Behler

Hello, everyone.

Ever since I bought it back in 2018, my Dell Windows laptop gets very laggy when using Jaws on battery power.

In other words,when I type, there is about a one-half to one second delay between when I hit a key, and when Jaws responds.

I have taken this computer to the Best Buy Geek Squad, and they can’t seem to get to the bottom of the issue.

The computer runs fine with Jaws when plugged into normal AC power, which is how I operate most of the time.

I’m thinking some sort of a setting needs to be changed, but I can’t find where it might be.

Any help would be appreciated.

Thanks!

Hello again.

To the person who suggested that I check battery saver settings, I did so, and battery saver is slated to kick in when my battery goes down to 20%.

The lagging issue with Jaws occurs no matter how much battery capacity I have, and occurs only on battery power.

The computer works fine when plugged into commercial AC power.

Tom,

I would go into control panel and sound settings and check the priority level of your soundcard, and set it to a higher level, which I think is reflected by a lower number.

It may have a designated low priority.

I've done this in windows 7, so you should be able to do this in newer windows versions.

HTH.

I hear you, but remember, everything is fine when running the PC on normal commercial AC power.

The lagging occurs only on battery power.

This is why I think the issue has something to do with battery settings, but I can’t figure out what that might be.

Hi Tom,

I still think it can be a priority issue, because the computer would put less resources into the soundcard on battery.

I’m going to echo Glenn’s idea and go adjust this on my own HP laptop. My HP laptop gets a lag with JAWS, even before the low battery warning. I wouldn’t doubt there is something to the prioritization of resources as the battery level diminishes.

Greetings:

I have a thought about this problem. Could you try turning on the JAWS setting “Avoid speech cut off when using Bluetooth headphones or some sound cards”. Go into Settings Center by pressing JAWSKEY+6. Search for the word “avoid” and press space to check this setting.

Does this help with the problem, yes or no?

Thank you.

Cordially,

Curtis Chong

The trouble is, not all sound cards allow themselves to be prioritized.

It may also be found in device manager for the soundcard.

But I have changed this before, it's in a list of the driver properties.

I just looked at the thread in this link, but the original poster to the thread never got back to say if it actually solved the issue.

That is why it is important for us to let the list know what actually worked for us when suggestions are made to a post.

Dell listed it as solved, but that may be because there was no more posts on the thread.

Also, maybe not exactly related to lag on battery, but I also go into system performance settings and change it from best for visual to just best performance for programs.

I would go into control panel and sound settings and check the priority level of your soundcard, and set it to a higher level, which I think is reflected by a lower number.

It may have a designated low priority.

I've done this in windows 7, so you should be able to do this in newer windows versions.

HTH.

Hello again.

To the person who suggested that I check battery saver settings, I did so, and battery saver is slated to kick in when my battery goes down to 20%.

The lagging issue with Jaws occurs no matter how much battery capacity I have, and occurs only on battery power.

The computer works fine when plugged into commercial AC power.

Hello, everyone.

Ever since I bought it back in 2018, my Dell Windows laptop gets very laggy when using Jaws on battery power.

In other words,when I type, there is about a one-half to one second delay between when I hit a key, and when Jaws responds.

I have taken this computer to the Best Buy Geek Squad, and they can’t seem to get to the bottom of the issue.

The computer runs fine with Jaws when plugged into normal AC power, which is how I operate most of the time.

I’m thinking some sort of a setting needs to be changed, but I can’t find where it might be.

Any help would be appreciated.

Thanks!

David:

If I’m understanding it correctly, the suggested solution is to put everything to never, which would mean that, on battery power, the computer never goes to sleep.

I’m not sure I want to do this.

Right now, I have it set to go to sleep if not used for 10 minutes.

I have the same ten-minute setting for turning off the screen.

I think that if the lag happens after 10 minutes, then that is the issue, but if the lag is there always, then power settings are not likely the culprit.

Hello Tom,
I suspect that the lag on battery has something to do with the power
options set on the PC as David suggested in a previous post. I would
suggest going to the control panelgo into power options and adjust
advanced power settings for this plan. Under this, I suggest expanding
the options for processor powermanagement and expand maximum processor
 state and set this to 100%and tab to the apply button and then tab to
the ok button. In my opinion, this should cause the PC to run faster
when on battery.

Tom,

I will paste an article I found on Windows prioritization of processes below, and a link to the article is at the end.

Do you have any anti malware programs running that may be taking system processes?

You might look in task manager to see what is running.

Glenn

Article Start:

I/O Prioritization in Windows OS
I/O prioritization improves the responsiveness of the system without significantly decreasing the throughput of the system. Typically, any topic related
to I/O and threads requires a good understanding of Windows synchronization because of that, I will try to discuss everything from the ground up.
In this paper, I am going to discuss how can we as the application or device driver developers take advantage of I/O prioritization in the Windows OS.
Finally (in the next paper, I will discuss the I/O completion mechanism of Windows) which is a magical feature.

Introduction
As you may know, after introducing Windows Vista (NTkernel release 6.0), Microsoft has improved the NT kernel ecosystem from different aspects. For example,
the Vista operating system implements new features for mitigating I/O bottlenecks.
Since disk or network I/O is often the performance bottleneck and many processes must contest for I/O access, so I/O prioritization in Windows NT6 was
widely acclaimed. Unfortunately, it isn’t fully in use yet. As you’ll see, there are only two application usable levels — Normal and Very Low (Background
mode) in Vista but it may be more levels in post vista operating systems like Windows 7, 8.1, or 10.
The application mechanism which Microsoft provided is to enter into a background mode via the SetProcessPriorityClass and/or SetThreadPriority API. However,
these can not be set for external processes, only the calling process. This lets the OS control all priorities, setting to an appropriate background I/O
priority, and an Idle CPU priority.
Note there are also distinguishing features added to nt6 like the new Multimedia Class Scheduler service and also Bandwidth Reservation. These features
attempt to guarantee I/O availability for playback in programs like Windows Media Player that register themselves with the Multimedia Scheduler. This is
what you should do if you need reliable bandwidth streaming in.
Though, besides these improvements, Microsoft has made a lot of improvements for security issues on the Vista operating system include User Account Control,
parental controls, Network Access Protection, a built-in anti-malware tool, and new digital content protection mechanisms which these feature will not
be discussed in this article.
I am going to discuss in this paper the need for prioritization, describes the various tactics that Microsoft uses to keep the system responsive, and provides
information and guidelines for application and device driver developers to leverage these approaches.

Slide 2: Process/Threads Priorities in Windows by Milad Kahsari Alhadi
Slide 2: Process/Threads Priorities in Windows by Milad Kahsari Alhadi figure end
The I/O Prioritization Concept
To keep the operating system throughput and also its responsiveness balanced, processes and also threads are given priorities so that more critical processes/threads
are scheduled more frequently or given longer time slices (quantum slices). However, with today’s advanced systems, even low-priority background threads
have the resources to create frequent and large I/O requests.
These I/O requests are created without consideration of priority. Consequently, threads create I/O without the context for when the I/O is needed, how
critical the I/O is, and how the I/O will be used. If a low-priority thread gets CPU time, it could easily queue hundreds or thousands of I/O requests
in a concise time.
Because I/O requests typically require time to process it is possible that a low-priority thread could significantly affect the responsiveness of the system
by suspending high-priority threads, which prevents them from getting their work done. Because of this, you can see a machine become less responsive when
executing long-running low-priority services such as:
list of 5 items
• disk defragmenters,
• multimedia based apps,
• anti-ransomware apps,
• networked-based apps
• and so on.
list end
However, every thread has a base-priority level determined by the thread’s priority value and the priority class of its process. The operating system uses
the base-priority level of all executable threads to determine which thread gets the next slice of CPU time.
So if we wanted to know what is the base priority of a thread, we can call GetThreadPriority and GetProcessPriority to retrieve the priority level and
the priority class of a process in a sequence. In the following photo, you can see a binary called these APIs to specify the current priority level of
a process and a thread.
figure
Unlabeled 0
figure end
Threads are scheduled in a round-robin fashion at each priority level, and only when there are no executable threads at a higher level will scheduling
of threads at a lower level take place.
block quote
For a table that shows the base-priority levels for each combination of priority class and thread priority value, refer to the slide 3 photo of this article.
block quote end
So the rest of this section explores the required context to properly prioritize I/O requests. However, threads are scheduled to run based on their scheduling
priority. Each thread is assigned a scheduling priority.
As you can see in the above slide, the priority levels range from zero (lowest priority) to 31 (highest priority). Only the zero-page thread can have a
priority of zero. The zero-page thread is a system thread responsible for zeroing any free pages when there are no other threads that need to run.

The purpose of I/O prioritization is to improve system responsiveness without significantly decreasing overall throughput. System advances have often focused
on improving the performance of the CPU to improve the work-throughput capabilities of the system.
block quote
Input and output (I/O) devices allow us to communicate with the computer system. I/O is the transfer of data between primary memory and various I/O peripherals.
Input devices such as keyboards, mice, card readers, scanners, voice recognition systems, and touch screens enable us to enter data into the computer.
Output devices such as monitors, printers, plotters, and speakers allow us to get information from the computer.
block quote end
I/O devices have also focused on improvements to throughput. However, the largest performance bottleneck for media or storage based devices is armature
seek time, which is often measured in milliseconds.
Base Priority Table by Milad Kahsari Alhadi figure
Unlabeled 0
Base Priority Table by Milad Kahsari Alhadi
Base Priority Table by Milad Kahsari Alhadi figure end
So, it is easy to see how low-priority threads might be capable of flooding a device with I/O requests that starve the I/O requests of a higher-priority
thread. Like the Windows thread scheduler, which is responsible for maintaining the balance among threads that are scheduled for the CPU, the I/O subsystem
must take on the responsibility of maintaining the same kind of balance for I/O requests in the system.
block quote
For both thread scheduling and I/O scheduling, the balance is driven not only by the need to optimize throughput but by the need to ensure an acceptable
level of responsiveness to the user.
block quote end
When optimizing for more than just throughput, throughput might be sacrificed in favor of quickly completing the I/O request for which a user is waiting.
When responsiveness is considered, the user’s I/O is given higher priority. This causes the application to be more responsive, even though overall I/O
throughput might decrease.
If the system thread’s I/O is serviced first at the cost of the application’s ability to make progress, the user notices the system as slower, even though
throughput is actually higher.
I/O Access Patterns
Also, in the following photo, you will see a complete categorization of I/O access patterns but I will simply explain the whole concept in the following
paragraphs.
I/O Access Patterns figure
I/O Access Patterns
I/O Access Patterns figure end
To ensure that throughput is not sacrificed more than is required to maintain responsiveness, I/O access patterns must be considered. The reasons for copying
data from a device into memory can be categorized into a few simple scenarios:
list of 5 items
1. The OS might copy in binary files to be executed, or it might copy in data that executable programs might need. An example would be launching Microsoft
Word.
2. An application might open a data file for use in its completeness. An example would be loading a Microsoft Word document so the user can edit the document.
3. The file system might read in or write file system metadata when a file is created, deleted, moved, or otherwise modified. An example would be creating
a new Word document.
4. A background task might attempt to do work that is not time-critical and should not interfere with the user’s foreground tasks. An example would be
antivirus software that is scanning files in the background.
5. An application might open a data file for use as a stream. An example would be playing a song in VLC Player.
list end
Loading Access Pattern
Most I/O access falls into the pattern of the atomic load before use, or paging, gather and flush. Scenarios 1 to 3 fall into this category.
For example, a program that is to be executed must first be loaded into memory. For this to happen, a set of I/O must be completed as a group before execution
can start. The system might use techniques to page out parts of an executable for the sake of limited system resources, but it does so by applying the
atomic load before use rule to subsections.
After a program is running, it often performs tasks on a data file. An example is Microsoft Word, which performs tasks on .doc files. Loading a data file
involves another set of I/O that must be completed as a group before the user can modify the file. Saving the modified file back to the device involves
yet another set of I/O that must be completed as a group. In this way, applications that load data files follow the atomic load before use the pattern
on their data files.
Finally, when the file system updates its metadata because of actions that the user performs on the system, the file system must also atomically read or
write its metadata before it may proceed with other operations that depend on that metadata.
All of these scenarios follow the same access pattern. However, depending on the user’s focus at any given time, the urgency of each set of I/O operations
might change.
Additionally, I/O processing of threads may depend on each other and require some I/O to complete before other I/O can be started. File system I/O often
finds itself in this situation. Improving the responsiveness of the system requires a method to ensure that I/O is completed in a certain order.
Passive Access Pattern
A variation on atomic load before use is an application that is working to accomplish a set of I/O operations but grasps that it is not the focus of the
user and consequently should not interfere with the responsiveness of what the user is working on. Scenario 4 falls into this category.
System processes that operate in the background often find themselves in this role. A background defragmenter is an example of such a service. A defragmented
device has better responsiveness than a fragmented storage device because it requires fewer costly queries to accomplish file reads and writes.
However, it would be counterproductive to cause the user’s application to become less responsive due to the large number of I/O requests that the defragmenter
is creating.
Passive access patterns are used by applications whose tasks are often considered noncritical maintenance. Fundamentally, this means that the applications
are not supposed to finish a task as soon as possible because their tasks are always ongoing. Such applications are not required to be responsive and must
have a way to allow activities that require responsiveness to proceed unimpeded.
Streaming Access Pattern
The opposite of the atomic load before the use pattern is the streaming I/O pattern. In this kind of access, the application does not require all of the
I/O in a set to be completed before it can begin its task; it can begin processing data from the completed I/O in parallel with retrieving the next set
of data.
The application requires the I/O to be accomplished in a specific order, and it requires the process to be acceptably responsive, potentially within real-time
limits. Scenario 5 falls into this category.
An example of an application that uses a streaming I/O access pattern is Windows Media Player. For this type of application, the purpose of the application
is to progress through the I/O set. Additionally, many media applications can compensate for missing or dropped frames of data.
For this reason, a device that puts forth a large effort to accomplish a read might be taking the worst course of action because it holds up all other
I/O and causes glitches in the media playback.
How can we change the priority?
Aside from using the documented background mode priority class for SetPriorityClass, you can manually tweak the I/O priority of a running process via the
NT Native APIs.
Retrieving the process I/O priority is simple. If you know how to call any API, you can call these APIs. There is documentation on the web about them,
and the below paragraph will summarize their usage in setting and retrieving I/O priorities.
NtQueryInformationProcess and NtSetInformationProcess are the NT Native APIs to get and set different classes of process information, respectively. For
retrieval, you simply specify the type (class) of information and the size of your input buffer.
It returns the requested information or the needed size of the buffer to get that information. The Set function works similarly, except you know the size
of data you are passing to it. However, in the following sections, we will discuss the I/O prioritization strategies that correspond to the access patterns
that were described earlier.
Hierarchy Prioritization Strategy
The atomic transfer before use scenario that was described earlier can be addressed by a mechanism that marks an I/O set in a transfer for preferential
treatment when the I/O set is being processed in a queue.
A hierarchy prioritization strategy effectively allows marked I/O to be sorted before it is processed. This strategy involves several levels of priority
that can be associated with I/O requests and thus can be handled differently by drivers that see the requests. Windows Vista currently uses the following
priorities: critical (memory manager only), high, normal, and low.
Before Windows Vista, all I/O was treated equally and can be thought of as being marked as a normal priority. With hierarchy prioritization, I/O can be
marked as high priority so that it is put at the front of the queue. This strategy can take on finer granularity, and other priorities such as low or critical
can be added. In this strategy, I/O is processed as follows:
list of 4 items
• All critical-priority I/O must be processed before any high-priority I/O.
• All high-priority I/O must be processed before any normal-priority I/O.
• All normal-priority I/O must be processed before any low-priority I/O.
• All low-priority I/O is processed after all higher priority I/O.
list end
For a hierarchy prioritization strategy to work, all layers within the I/O subsystem must recognize and implement priority handling in the same way. If
any layer in an I/O subsystem diverges in its handling of priority, including the hardware itself, the hierarchy prioritization strategy is at risk of
being rendered ineffective.
Idle Prioritization Strategy
The non-time-critical I/O scenario that was described earlier in this paper can be addressed by a mechanism that marks the set of I/O in a transfer to
yield to all other I/O when they are being processed in a queue. Idle prioritization effectively forces the marked I/O to go to the end of the line.
The idle strategy marks an I/O as having no priority. All I/O that has a priority is processed before a no-priority I/O. When this strategy is combined
with the hierarchy prioritization strategy, all of the hierarchy priorities are higher than the non-priority I/O.
Because all prioritized I/O goes before no-priority I/O, there is a very real possibility that a very active I/O subsystem could starve the no-priority
I/Os. This can be solved by adding a trickle-through timer that monitors the no-priority queue and processes at least one non-priority I/O per unit of
time.
For an idle prioritization strategy to work, only one layer within the I/O subsystem must recognize and implement the idle strategy. After a no-priority
I/O has been released from the no-priority queue, the I/O is treated as a normal-priority I/O.
Bandwidth-Reservation Strategy
The streaming scenario described earlier in this paper can be addressed by a mechanism that reserves bandwidth within the I/O subsystem for use by a thread
that is creating I/O requests. A bandwidth-reservation strategy effectively gives a streaming application the ability to negotiate a minimum acceptable
throughput for I/O that is being processed.
A bandwidth reservation is a request from an application for a certain amount of guaranteed throughput from the storage subsystem. Bandwidth reservations
are extremely useful when an application needs a certain amount of data per period of time (such as streaming) or in other situations where the application
might do bursts of I/O and require a real-time guarantee that the I/O will be completed in a timely fashion.
The bandwidth-reservation strategy uses frequency as its priority scheme. This allows applications to ask for time slices, such as three I/Os every 50
ms, within the I/O subsystem. When coupled with the hierarchy prioritization strategy, streaming I/O gets the same minimum number of I/Os per unit of time,
independent of the mix of critical‑, high‑, normal‑, and low-priority I/Os that are occurring in the system at the same time.
For this strategy to work, only one layer within the I/O subsystem must recognize and implement the bandwidth reservation. Ideally, this layer should be
as close as possible to the hardware. After an I/O has been released from the streaming queue, it is treated as a normal-priority I/O.
Implementing Prioritization in Applications
Applications can use several Microsoft Win32 functions to take advantage of I/O prioritization. This section gives a brief overview of the functions that
are available and discusses some potential usage patterns. Developers should consider the following when adjusting application priorities:
list of 2 items
• Whenever an application modifies its priority, it risks potential issues with priority inversion. If an application sets itself or a particular thread
in the application to run at a very low priority while holding a shared resource, it can cause threads that are waiting on that resource with higher priority
to block much longer than they should.
• Applications that use streaming should also be sensitive to causing starvation in other applications, although there is a hard limit on the amount of
bandwidth that an application can reserve.
list end
Setting the Priority for Hierarchy and Idle
An application can request a lower-than-normal priority for I/O that it issues to the system. This means that the requests that the I/O subsystem generates
on the application’s behalf contain the specified priority; at that point, the driver stack becomes responsible for deciding how to interpret the priority.
Therefore, not all I/O requests that are issued with a low priority are, in fact, treated as such.
Most applications use the process priority functions such as SetPriorityClass to request a priority. SetPriorityClass sets the priority class of the target
process. Before Windows Vista, this function had no options to control I/O priority. Starting with Windows Vista, a new background priority class has been
added. Two values control this class: the first sets the mode of the process to background and the second returns it to its original priority.
#include <windows.h>
#include <iostream>int main(int argc, char* argv[])
{
// Now all threads in a process will make low-priority I/O requests.
SetPriorityClass(GetCurrentProcess(), PROCESS_MODE_BACKGROUND_BEGIN);// Now primary thread issue low-priority I/O requests.
SetThreadPriority(GetCurrentThread(), THREAD_MODE_BACKGROUND_BEGIN);DWORD dw_priority_class = GetPriorityClass(GetCurrentProcess());
std::printf("Priority class is 0x%x\n", dw_priority_class);DWORD dw_priority_level = GetThreadPriority(GetCurrentThread());
std::printf("Priority level is 0x%x\n", dw_priority_level);SetPriorityClass(GetCurrentProcess(), PROCESS_MODE_BACKGROUND_END);
SetPriorityClass(GetCurrentProcess(), THREAD_MODE_BACKGROUND_END);return 0;
}
The following call starts background mode for the current process:
SetPriorityClass(GetCurrentProcess(),PROCESS_MODE_BACKGROUND_BEGIN);
The following call exits background mode:
SetPriorityClass(GetCurrentProcess(), ROCESS_MODE_BACKGROUND_END);
While the target process is in background mode, its CPU, page, and I/O priorities are reduced. From an I/O perspective, each request that this process
issue is marked with an idle priority hint (very low priority). A similar function for threads, SetThreadPriority, can be used to cause only specific threads
to run at low priority.
Finally, the SetFileInformationByHandle function can be used to associate a priority for I/O on a file-handle basis. In addition to the idle priority (very
low), this function allows normal priority and low priority. Whether these priorities are supported and honored by the underlying drivers depends on their
implementation (which is why they are referred to as hints).
FILE_IO_PRIORITY_HINT_INFO priorityHint;
priorityHint.PriorityHint = IoPriorityHintLow;
result = SetFileInformationByHandle(hFile, FileIoPriorityHintInfo, &priorityHint, sizeof(PriorityHint));
Reserving Bandwidth for Streaming
Applications that stream a lot of data, such as audio and video, often require a certain percentage of the bandwidth of the underlying storage system to
deliver content to the user without glitches.
The addition of bandwidth reservations, also known as scheduled file I/O (SFIO), to the I/O subsystem exposes a way for these applications to reserve a
portion of the bandwidth of the disk for their usage.
Applications can use the GetFileBandwidthReservation and SetFileBandwidthReservation functions to work with bandwidth reservations:
BOOL
WINAPI
GetFileBandwidthReservation(
__in HANDLE hFile,
__out LPDWORD lpPeriodMilliseconds,
__out LPDWORD lpBytesPerPeriod,
__out LPBOOL pDiscardable,
__out LPDWORD lpTransferSize,
__out LPDWORD lpNumOutstandingRequests
);BOOL
WINAPI
SetFileBandwidthReservation(
__in HANDLE hFile,
__in DWORD   nPeriodMilliseconds,
__in DWORD   nBytesPerPeriod,
__in BOOL    bDiscardable,
__out LPDWORD lpTransferSize,
__out LPDWORD lpNumOutstandingRequests
);
An application that requires a throughput of 200 bytes per second from the disk would make the following call:
result = SetFileBandwidthReservation(hFile, 1000, 200, FALSE, &transfer_size, &outstanding_requests);

David:

If I’m understanding it correctly, the suggested solution is to put everything to never, which would mean that, on battery power, the computer never goes to sleep.

I’m not sure I want to do this.

Right now, I have it set to go to sleep if not used for 10 minutes.

I have the same ten-minute setting for turning off the screen.

I am late to this thread but I did a web search for Dell Laptop laggy on battery power and the first result was pointed to a Dell Support page.

Have you reviewed this? There is a suggested amendment to power settings.

I hear you, but remember, everything is fine when running the PC on normal commercial AC power.

The lagging occurs only on battery power.

This is why I think the issue has something to do with battery settings, but I can’t figure out what that might be.

Tom Behler

Tom,

I would go into control panel and sound settings and check the priority level of your soundcard, and set it to a higher level, which I think is reflected by a lower number.

It may have a designated low priority.

I've done this in windows 7, so you should be able to do this in newer windows versions.

HTH.

Hello again.

To the person who suggested that I check battery saver settings, I did so, and battery saver is slated to kick in when my battery goes down to 20%.

The lagging issue with Jaws occurs no matter how much battery capacity I have, and occurs only on battery power.

The computer works fine when plugged into commercial AC power.

Hello, everyone.

Ever since I bought it back in 2018, my Dell Windows laptop gets very laggy when using Jaws on battery power.

In other words,when I type, there is about a one-half to one second delay between when I hit a key, and when Jaws responds.

I have taken this computer to the Best Buy Geek Squad, and they can’t seem to get to the bottom of the issue.

The computer runs fine with Jaws when plugged into normal AC power, which is how I operate most of the time.

I’m thinking some sort of a setting needs to be changed, but I can’t find where it might be.

Any help would be appreciated.

Thanks!

Curtis:

I went into default all applications, and checked the avoid speech cut-off setting, and the problem seems better now.

In fact, I’m typing this reply on battery power.

The lag isn’t totally gone, but at least the delay isn’t as significant as it originally was.

Thanks!

Does this help with the problem, yes or no?

Thank you.

Hi Tom,

I still think it can be a priority issue, because the computer would put less resources into the soundcard on battery.

Power management has become way more than a bit confusing because "everyone's trying to get in on the game:" Windows, UEFI/BIOS, and, sometimes, manufacturer-specific utilities.

You have to check UEFI/BIOS to see if any power management is enabled at that level because, if it is, nothing Windows does will undo the settings at that level.

In Windows, if you open Control Panel, Power Options, and are in the part of Power Options where you choose your Power Plan, if the Ultimate Performance power plan is available, choosing it turns off all background management of power for individual devices by Windows. If you don't see it, you can enable it by opening either Command Prompt or PowerShell as administrator, then entering the following command: powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61
After having done this, if you check Power Options again, the Ultimate Performance scheme should be available to choose.

There should be no reason for a laptop to perform differently on battery power than on AC power unless some form of power management is at play.
