Ryzen 3 2200U capped at 400MHz when switched on using Battery

Product Name: HP 14-cm0010AX
Operating System: Microsoft Windows 10 (64-bit)

Hi. 

I have a 14-cm0010AX notebook sporting the Ryzen 3 2200U. I kept seeing a strange behavior, if the laptop came from a cold start, the CPU 's max speed is capped at 400MHz, making everything quite slow. 

I have tested different drivers, and it does seem a bit of a hit and miss, with slow performance as reported by Task Manager when the CPU was capped at 400MHz. 

Please help.

Re: Ryzen 3 2200U capped at 400MHz when switched on using Battery

@madfry,

 

Welcome to the HP Forums!

 

Thank you for posting your query on this forum, it's a great place to find answers.

 

I reviewed your post and I understand that the CPU speed is capped at 400MHz.

 

Don’t worry, I assure you I will try my best to get this sorted.

 

In order that I may provide you with an accurate solution, I will need a few more details.

  • When was the last time the computer was working fine?
  • Have you made any software or hardware changes on the computer?
  • Have you performed any troubleshooting steps before posting?

While you respond to that, I recommend you update the BIOS of the computer from the below link and check whether the issue is resolved.

 

https://ftp.hp.com/pub/softpaq/sp88501-89000/sp88549.exe

 

If you continue to face the issue, I recommend you install all the Windows update and test.

 

Here is how it is done.

  1. Connect the computer to the internet.
  2. Click on Start.
  3. Select Settings.
  4. Select Update & security.
  5. Select Windows Updates.
  6. Select Check for updates.
  7. Windows Update will download and install the drivers automatically.

Let me know how it goes and you have a great day!

Re: Ryzen 3 2200U capped at 400MHz when switched on using Battery

Yes, I have already updated to the latest F10 BIOS. 

 

The problem happens sporadically, but it does seem to crop up more often if I started the laptop using battery power without connecting it to the power adaptor. 

It started even when I first got the laptop. Tried updating the drivers using the ones from HP website, still the slowdown crops up. Only way then is to stick the AC power in, reboot to get it functioning normally. 

 

I had to take a screenshot of the task manager showing the cap. Printscreen doesn't work.

@madfry

It looks like you were interacting with @The_Fossette, but he is out for the day & I'll be glad to help you out,

I'm the Flower_Bud & I'm at your service.

 

Have you updated the Windows suggested by The_Fossette?

 

I would suggest you update Chipset drivers from our HP website.

 

Run system test: 

  • Press the Power button to turn on the computer and immediately press the F2 key repeatedly, about once every second, until you see HP PC Hardware Diagnostics UEFI.
  • From the UEFI main menu, click System Tests, then click Quick Test.
  • Click Run once.
  • While the test is running, the time remaining and test result for each component are shown on the screen. The test can take up to 15 minutes.
  • If no system component failed, please go back to main menu and Exit from the screen

If a component fails a test, write down the information so you have it available.

 

If the test passes, you could create a new user account and check the functionality: 

 

If the issue persists, please perform a push-button resethttps://support.hp.com/us-en/document/c04742289.

 

NOTE: Back up your personal data before performing a push-button reset.

 

Keep me posted,

Have a great day :)

Cheers :)

System Quick Test : Everything passed. 

Change user accounts - Did that also, still happens. 

Reset the whole thing - Did that also, still happening.

Re: Ryzen 3 2200U capped at 400MHz when switched on using Battery

Apart from the strange CPU speed cap, something else came up. 

 

The discrete graphics seems to have developed a problem where every output looks bluish. So it is safe to say that this is a hardware problem already and I have sent the unit back to the retailer, who was gracious enough to exchange the unit on the spot. 

 

The unit is working fine right now, but I am still testing everything out, hopefully this time there wouldn't be any more nasty surpises waiting.

Spoke too soon. 

There was no issue, until Windows forced upgraded itself to 1803, and all DirectX 11 color issues all came back. 

 

What now?
