the issue arose after the battery of my Surface Pro 2017 stopped charing beyong 0% (I believe its completely gone now, as runtime on battery was already less than half an hour! and I was using the device almost exclusively plugged in)
Description of the problem:
maximum CPU utilization (as reported in Task Manager) is limited to 14 %
and maximum CPU frequency (again as seen in Task Manager) always stays at 0.38 GHz
My question now is: is there another way than to replace the battery to get CPU utilization and frequency back to normal (up to 100% and up to ~3.50GHz) for example through modifying the registry?
Things I have tried so far to no avail:
- uninstalling battery in device manager (with removing the driver)
- uninstalling battery and AC adapter in device manager
- deactivating the battery in the device manager
- changing performance mode in windows settings
-> after each of these changes I rebooted the system.
One thing that might complicate things a bit: I am currently running the Windows 11 Pro Insider Preview Build 25247.rs_prerelease.221114-1311 on my device
