Windows 10: Laptop CPU throttle after battery failure

Recently, my laptop battery stopped working, and ever since, I've noticed that sometimes when I boot up my laptop, the CPU clock is significantly lower than normal, my CPU base is 3.0 GHz and it lowers down to 0.2 GHz! Making the laptop almost unusable and booting it is really slow. Interestingly, as soon as I open ThrottleStop, the CPU speed returns to normal and stays stable afterward. I think it has something to do with the "BD Prochot" Settings, I untick it and it goes fine, though my laptop wasn't overheating when that happens.This issue seems to happen especially when I don't shut down m

Prevent Cpu throttle on Battery

Hello,

I recently upgraded my Laptop by adding an SSD with windows 10 pro.

Now I noticed the computer throttles the cpu frequency whenever I'm on battery even on high performance profile.
(In task manager I can see cpu frequency instantly dropping from 2.3-2.5 to 1.2 GHz as soone as I unplug the AC adapter).

The issue is not bios related and It does not happen on Ubuntu nor window 7( I mesured and the cpu frequency does not change when I unplug).

I tried the following:
- High performance profile.
- increased "minimum processor state" in power plan settings to 60% (https://i2.wp.com/www.techconsumergu...ng?w=452&ssl=1)
- Computer Configuration > Administrative Templates > System > Power Throttling Settings and I Enabled the "turn off power throttling"


Still windows 10 throttles whenever I'm on battery.

Can someone suggest a solution for this?

Thanks in advance

 

Prevent Cpu throttle on Battery

Setting the CPU minimum to something higher will not make any difference to performance, only increases power consumption/heat when the CPU does not have to work hard.
The title of the thread is wrong to call it throttling. The CPU is designed to increase up to the turbo max when demands are made on the CPU.

" I'm assuming setting it at 100% will make the CPU run at 2.8 GHz constantly"
Not on my Laptop.
The nominal clock is 2.5 GHz, however the turbo range or speed stepping ranges from 800 MHz to 3.1 GHz.
On the so-called "Best performance" setting the CPU has a 2.5 GHz idle frequency/min, but it still turbos up to 3.1 GHz when required.
The next setting down "Better performance" has the full stepping range from 800 MHz to 3.1 GHz.
On testing this with something taxing the CPU, "Better performance" setting is just as good as "Best" but with less power consumption between tasks.

The tinkering with settings by modding the Registry is pointless.

The Power Plans indicated are no more on the latest iteration of Windows 10 anyway.

"I may set it at 25% instead of 5% that it's defaulted to while plugged in. "

I doubt if that will do anything, it depends on the stepping range of the CPU clock allowed for your particular CPU. as you can see with mine it won't make a hoot of a difference. If it is set to 5% nothing happens it is still 800 MHz minimum(26%).

 

Laptop Startup on Battery Failure

Another thing you could usefully look at is Device Manager. You should find 'ACPI-Compliant Control Method Battery' under Batteries. Try uninstalling it then let Windows scan for new hardware and reinstall it.
