Hi,
I have HP Pavilion 15-cw0002 laptop with AMD Ryzen 2500U CPU but I have major issue running the laptop on battery. I am running Windows 10 Home 64 bit. Whenever I turn on the laptop when disconnected from the AC adapter, the CPU speed is capped to 400MHz. The speed does not change no matter how CPU intensive program I run. It is only remedied by a restart or by plugging in the laptop.
I am attaching screenshot from CPU-Z showing CPU speed & Mainboard//BIOS info. I have also attached a screenhshot of Windows Task Manager showing the low CPU speed According to CPU-Z it seems that the multiplier is set to x4 which seems incorrect or?
Steps I have taken so far to remedy the issue:
- Install all available BIOS updates
- Install all available Windows Updates
- Install latest available drivers for all components
- Reset Windows several times
The issue seems to be persistent. Is this a know issue? What can I do to fix for this?
Regards,
Mohsin
