Re: AMD Ryzen 5 2500U locked to 400MHz on battery

Did you do the test that I told?

Go to msconfig > Boot > Boot Options > Safe Boot > then check minimal.

What the results you get? please tell us

Re: AMD Ryzen 5 2500U locked to 400MHz on battery

It made no difference, I even reinstalled Windows 10 from original install media so there were no HP specific power plans and the same thing occured.

There is no point trying to fix it, it's beyond the consumers capabilities, we just have to wait for firmware because it's to do with an error in the OCP (over-current protection) algorithm I'm told.

Looks like with the latest F.17 BIOS update, the issue has now been resolved.

Wonder if HP would issue a similar update for the 14-cm0072au.

Re: AMD Ryzen 5 2500U locked to 400MHz on battery

Hi, my friend bought HP 17-ca0013nm with Ryzen 5 2500U and laptop came with F13 BIOS and I encountered the same issue. CPU was running at 0,38GHz when powered on battery. Than I updated BIOS to F21 (latest) via HP Support Assistant and problem was solved. CPU now runs at full speed. Thx for this useful topic.

Got a firmware update on the Lenovo, so hope that helps.  Haven't had time to confirm it yet.

No such luck.  Both machines are still bricks.

Still no sign of a firmware update for my device though:

HP Notebook - 14-cm0072au - Driver Downloads | HP® Customer Support 

Latest BIOS is from November and that's the one I am using right now.
