Question How to speed up a Dell Vostro running on battery ?

[Tony Bullet]

Hi,

I have a Dell Vostro 7590 laptop with thefollowing specs:
Windows 10 Professional
Intel Core i7-9750H CPU @ 2.60GHz
32 GB RAM
C disk: SSD, 321 GB free of 464 GB.

This computer is extremely slow when running on battery. Yet the Windows setting via the battery icon is on High Performance.

When I go to “Control Panel / Hardware and Audio / Power Options”, I only have access to the “normal use” mode; I cannot access a “high performance” mode and I cannot change performance in this mode. In the «advanced settings», I only have access to the standby time, the screen shutdown, and the actions on low battery. But nothing about the processor or performance in general.

And if I’m looking to create a new mode, it’s the same thing, I don’t have the ability to adjust the performance.

In the «task manager», I see that my processor is running (currently) at 2%, at a speed of 1.3 GHz (for a base speed of 2.59 GHz)

So can anyone tell me how to increase battery performance to get the same as on mains?

Thank you!

Tony.

Using Task Manager, see what your resource usages are when both on battery power and wall outlet power. Something tells me your OS is corrupt and is need of a reinstall. Might be a good idea to see if your laptop is pending any BIOS updates as well.

Processor speeds up to more than 2.5 GHz, with peaks up to 4, when on wall outlet power. OS is not corrupt (it has been reinstalled clean 2 months ago. BIOS was updated some days ago. Antivirus works perfectly. The whole computer is very well maintained and updated. The problem has always been present, since the beginning (about 4 years).

It is a problem of settings: how and where can I force this computer to speed up on battery mode?

I entered the bios and "forced" maximum speed for processors. However it did not change anything in the behaviour of my computer, as I can check on Task Manager / Performances / Processor:
. when plugged on wall outlet power, speed is about 2.59 GHz (which is the base speed of the computer)
. when I unplug the computer, I can instantaneously see the speed dropping to about 1.6 GHz.
This is very annoying, because at this low speed, the computer reacts very slowly.
Therefore, I am searching a way to force the speed up when on battery mode, which I cannot find in the available options.
Thank you for your help.
Antoine.

Try using ThrottleStop. Post some screenshots if you need help.

Try clearing the BD PROCHOT box on the main screen and check the MMIO Lock box in the TPL window.
