CPU speed throttling when on battery

post #1 of 9
Thread Starter 
Hi Guys,

Ive got an annoying problem with my laptop that im really hoping someone on here can help me with.

When i run the laptop on the battery my cpu speed gets throttled right down leading to poor performance, even though im using the high performance plan in the power options (see image below)



Below is a screen shot running the dolphin emulator, as you can see the cpu speed is only at 1.6GHz. This leads to really poor in game performance, when i have the charger plugged in the games run at a full 60fps.



The only power option i have in the BIOS are:




System specs are:

HP Probook 650 G2
Intel i5 6200u
8GB DDR4 2133
Intel HD520
Windows 10 Pro

Thanks for reading.

note sure if related but:
https://www.reddit.com/r/techsupport/comments/3uipj0/after_upgrade_to_win10_cpu_is_constantly_throttled/

some people talking about a DPTF driver issue, had to roll back to the win8.1 driver instead of the win10 driver and it fixed their issue.

Disable runtime power management in the BIOS there. That is BIOS controlled CPU throttling.

That will obviously lower your battery life though so that is something to just to keep in mind.

I did come across that thread when i googled the problem but i dont think i actually have that driver installed.

I wonder if this issue might actually be related to the same sort of throttling issue I have with my toughbook... Subbed for any suggestions I'll try. (mine occurs on battery and charging)

What do your temps look like? It will throttle no matter what if its getting too hot. plugging in completely solves the issue?

Temps are fine (mid 30s). Yes, plugging in completely solves the issue and the cpu goes back to full speed (2.8Ghz)
