Laptop with i7 7700HQ only 60% cpu usage without adapter

[GuillaumeM]

So I recently bought a laptop for programming and VMs with an Intel i7 7700HQ, GTX 1050 and a 500GB NVMe SSD, and I truly love it. There is only one small "issue". When I'm working on the battery, my cpu seems to be locked to reach over 60% usage, so I can only reach a clockspeed of 1.68 GHz on all four cores, while it's reaching 3.81 GHz when powered by the adapter. Is there any way I could turn off this power-saving feature, because extra speed is always welcome 😉

You need to go to the Power Options and Advanced Settings on the specific power plan you are using and change the Maximum Processor State On Battery (under the Processor Power Management) to 100%.

That is one of the first things I'm doing when I set up a new computer for myself. I have also tried playing with the "Maximum processor frequency", yet without any positive result. Also the system is not thermal throttling, since the maximum temperatures are about 65°C.

Are you using the max performance profile rather than balanced?

 

[GuillaumeM]

I've set the energy profile to maximum performance and I checked every setting in the Advanced Energy menu. Also I searched the BIOS, but there's no power saving options over there.

 

[GuillaumeM]

Well I contacted the company and apparently the laptop is limited to 60% CPU usage on battery use, because the battery would die too fast if it would have to power both the GPU and CPU at once.

What laptop is that? so we know for future reference.

 

[GuillaumeM]

It is a Clevo N850HJ sold by BTO, so branded as a BTO 15CL71, a great laptop, except for this little power saving tweak it works absolutely perfect.

Throttlestop overrides this.
