Problem with CPU throttling when charging and playing a game.

[idata]

Hi, I recently (within about two weeks) acquired an HP Envy laptop with the following specs:

Quad-core Intel i5-5200U @ 2.20 GHz

NVIDIA 940M and Intel HD Graphics 5500 GPUs

8 GB Ram

Windows 10 64 bit

Yesterday when I tried to play a game known as Starbound, it was running fine until I plugged in the laptop to charge, then I got a huge permanent FPS drop that made the game unplayable. Today I've done some troubleshooting and found that the CPU speed is throttling to exactly 0.48 GHz when plugged in charging and playing a game. I've tested with another game, Garry's mod, to rule out that it's a problem with Starbound and indeed, the problem persists. It doesn't throttle immediately upon starting a game, but rather after a few minutes of playing.

Things I've tried:

• Checked advanced power plan settings for both High Performance and Balanced to see if anything could cause this
• Checked NVIDIA and Intel graphics settings in case the GPUs are causing this somehow
• Restarted multiple times
• Attempted to update drivers for both GPUs and CPU (installed NVIDIA driver update that had no effect)
• Run Starbound in Fullscreen, Borderless Window and Windowed mode, no effect
• Reset recently changed settings back to their defaults, no effect

I won't accept an external program as a solution to this, nor will I accept a system restore either - it's a new laptop with a relatively fresh install of Windows 10.

To re-iterate, the CPU throttles to 0.48 GHz from a maximum of 2.20 GHz when plugged in charging AND playing a game of some sort. It doesn't seem to throttle when just doing normal activities like browsing the web or using Skype. I use Steam to launch both these applications but nowhere does Steam seem to have a setting that could cause this.

What could be causing this?

Thank you for taking the time to read and consider this, I would very much appreciate any help provided.

I theorise that perhaps the CPU is throttling to allow the battery to charge faster, which makes sense since it reports that it'll only take a few minutes to charge to 100% from around 10%. I don't know what setting could be causing this, though...

Hello Lurmey:

I just wanted to check if you were able to install the drivers provided above, and if the problem still persists or if it got resolved? Any questions, please let me know. Alberto

Hi Alberto,

I explored the options you provided but found that my graphics drivers are all up-to-date already. I did a little more digging and found that a BIOS update could help.

Thus, I managed to resolve the issue by updating my BIOS with HP.

Thank you for your assistance.

Hello Lurmey:

Thank you very much for letting us know that information. Perfect, excellent, it is great to hear that the problem got resolved by doing a BIOS update. Any other inquiry, do not hesitate in contact us again. Regards Alberto

Hello Lurmey:

As you mentioned before, the case of the CPU throttling to allow the battery to charge faster could be very well the reason why this is happening, and at this point pretty much you tried all the troubleshoot steps that we recommend for this scenario. On the following link you will find the graphics driver for the Intel® HD Graphics 5500 controller, not sure if you tried those drivers already, but I Just wanted to make sure you tried the right ones: Beta driver 4539: https://downloadcenter.intel.com/download/26347/Intel-Beta-Graphics-Driver-for-Windows-10-and-Windows-7-8-1-15-40-?product=86210 https://downloadcenter.intel.com/download/26347/Intel-Beta-Graphics-Driver-for-Windows-10-and-Windows-7-8-1-15-40-?product=86210 Driver 4501: https://downloadcenter.intel.com/download/26228/Intel-Graphics-Driver-for-Windows-10-and-Windows-7-8-1-15-40-?product=86210 https://downloadcenter.intel.com/download/26228/Intel-Graphics-Driver-for-Windows-10-and-Windows-7-8-1-15-40-?product=86210 Also, you can try the graphics driver from HP, on the following link you can get that driver, I looked for it but it gave me an error message saying that there are many results for "HP Envy" http://support.hp.com/us-en/drivers/selfservice/identify?q=HP+Envy&tool=s-002# Z7_3054ICK0K8UDA0AQC11TA930O2 http://support.hp.com/us-en/drivers/selfservice/identify?q=HP+Envy&tool=s-002# Z7_3054ICK0K8UDA0AQC11TA930O2 As an option you can try to get in contact with HP directly in order to check if this problem is actually expected and that is how the laptop works or if maybe a BIOS update will fix it or they might have an specific driver for this type of issue, because remember that all the features and functions of a laptop are created by the manufacturer so they might have different troubleshoot steps in order to resolve it, maybe there is a setting on the BIOS to prevent this situation. Also maybe there is an specific driver from Nvidia that is required, so here is the link for their drivers: http://www.nvidia.com/download/index.aspx http://www.nvidia.com/download/index.aspx From our side to provide the drivers above is the best we can do for this matter, so please try them and let us know the results. Any questions, please let me know. Alberto
