RE: XPS 13 (2015) i7 CPU Speed (again)

Thanks, for posting your trouble here. Did you find a final solution after all? I have the same issue with Power Companion. CPU is also limited to 0.48, but I didn't realise it was only after sleep mode. Really annoying problem actually

Well it's a workaround, but it kills battery life. It is a bug on Dells side and it should be fixed with a bios update.

RE: XPS 13 (2015) i7 CPU Speed (again)

Just to throw my hat in to the ring here. I am having the same issue with my XP3 13 9343 i5. The last week or so I have noticed that intermittently it would drop the CPU down to 0.46 - 0.48GHz and stay there until I reboot (or sometimes something else will trigger it to go back to normal, maybe coming back from sleep? I havent fully tested yet).

This happens to coincide with when I bought the Dell Power Companion. I cant say for certain, but it seems to happen when I use the Power Companion.

Anyone found a fix for this yet?

Hi,

In my case the minimum and maximum CPU power consumption was set to 5%. You have to go to the advanced power settings, processor power management, minimum/maximum processor state. You might have different power plans for when you have your machine plugged in and when not. So you would have to change both of those..

Hope that helps and does the trick.

Best wishes,

Andreas

I've already checked this. Min was 5% and max was 100%.

Interestingly, even setting it to my 'max power' power scheme where min and max are both 100% it didn't resolve the issue. It seems to be a bug which cant be fixed by messing with the power schemes. A reboot fixed the problem though.

Another vote to blame the Power Companion. I plug my XPS-13 in at home through a power companion; don't have one at work. Only solution I had found was to shut down -- the problem persists across a restart. However, thanks to a previous post, I just tried sleeping with nothing plugged in (except a USB Human Interface Device... a Yubikey) and that seems to have fixed it.

I'm having the same issue, but it does not seem to be related to power companion. It happens for me when running on internal battery as well. About half the time when the machine wakes from sleep, the CPU is locked at .48GHz. Putting the machine back to sleep and waking again usually resolves it until the next time it sleeps. Anyone else found a fix or workaround other than the power companion thing?

Does not work. Same problem here. My Dell laptop is a Inspiron 13 2 in 1

Setting the power profile to high performance is working for me. Thanks...
