Dell G7 - CPU stuck at 0.8 GHz on Battery

It worked for me ! Now I an use my notebook on battery, finally! !

Hi,

I had a similar problem with new Precision series.

What helped is to go to control panel->change battery settings->change plan settings(only balanced shown if dell power manager is installed)->change advanced power settings->Processor power management->Maximum processor state:

on battery, it is 50% and if changed to 100% everything goes faster but keep in mind, that battery is drained also 2...3 times faster!

 It is quite annoying that there is no easy way to adjust processor speed for each power manager "level"

Currently thinking of deleting Dell Power Manager completely and rely completely on Windows 10 power plans. If I have time to test it out, I will let you know how battery life was affected also.

Thanks for your sharing. Unfortunately I already make this changes and I did not get better performance.

what exactly did you do? There are many solutions offered in that thread.

Jump to solution!

Can you please elaborate on this. How were you able to resolve the problem. Is it the same mentioned in XPS solution (Disconnecting battery, holding power button for 3-45 seconds).??

so you unplugged the battery and how you arent throttling on battery power?

I've tried taking off the back twice, disconnecting the battery, holding the start button down for 30 seconds. And nothing has really worked. My G7 will jump up to maybe 1.2 - 1.5, but randomly it'll go right back to .79 GHz. I guess that's better than nothing but it still **bleep**. 

If anyone has an alternative solution to removing the battery, please let me know. Really annoying but I want this computer to work. I really like it. 

Just got the latest BIOS (v1.50) and it seems to have helped. Now the CPU drops to 1.6GHz under a stress test while on battery life. I can also play 4k youtube videos without stuttering (before I couldn't even do 1080p smoothly).

So either I got lucky, or the new bios solved the issue.

You guys are facing Power Limit Throttling!!! 

Only BIOS update can fix this permanently

Temporary fixes --

1)Undervolt your CPU using XTU. Watch this video  ---

2) Download ThrottleStop using the link https://www.techpowerup.com/download/techpowerup-throttlestop/

Now install it and you will see many options. Focus on "BD PROCHOT"

Uncheck it and then click on the save button

This will definitely work

BD prochot is something that underclocks the CPU when temps are too high to help run the CPU in a safe environment. Disabling it will stop any kind of throttling.

So guys use a cooling fan while playing games. After disabling bd prochot, the CPU temps can be very high so I suggest everyone to disable turbo boost and undervolt the CPU. Disabling turbo boost will reduce the CPU frequency to the base clock and hence reduce the heat produced. There is an option "Disable turbo" in ThrottleStop 

Do this at your own risk

Cheers!

I've been going crazy trying to fix this issue myself. I updated the BIOS, changed every power setting imaginable, and was still not able to stream any video without immense stuttering, my mouse was barely moving at some points. My wife has the same exact computer and I noticed she was having no issues doing anything on battery. I checked her power settings and saw she was using the default Dell plan included in the power options. I switched my option to the Dell one and no issues so far!

So it looks like I've found a solution (at least for the past two days). Here are the steps/notes I followed:

1. Kept the BIOS at 1.3 - I didn't want to upgrade the BIOS to 1.5, as I've heard there's been temp issues so I'm still azt 1.3 However, I have a suspicion that it's not BIOS related (I'll explain in point 4). So maybe you don't need to panic and downgrade. 
2. Removed the battery - I removed the back of the G7, unplugged the battery, held down the power button for 30 seconds, and put it back together, this helped somewhat but it was superficial, the throttling came back within minutes. 
3. Throttlestop profile for battery mode - I created a battery profile on Throttle stop to disable BD PROCHOT, undervolted the CPU Cach/Core to -125 hz. HOWEVER, after disabling MSI Afterburn (4th point below) I've disabled Throttlestop and the throttling stops as well, so maybe this step isn't necessary. 
4. MOST IMPORTANTLY: I disabled MSI Afterburner - I'm a bit of an **bleep**, but I didn't realize that MSI Afterburner was running in the background, I had my GPU overclocked to 152/58 hz, which I assume, was causing the throttling. With it off, or at 0/0 hz, I haven't been experiencing the .79 hz CPU throttle. 

Hopefully this helps you, with the dude who posted above about his wife who has a G7 as well, let me know if you happen to have MSI Afterburner running and she doesn't. If that's the case, 

I'm also using that bios revision. Sometimes I get lucky and the processor runs at 1.6G but sometimes it drops to 0.8/
