CPU stuck at low MHz all the time

Device: Lenovo laptop

Problem: CPU of sits at low clocks even when under load, even when temperature is relatively low, causing abysmal performance.


1. Quick EC reset While the laptop is running, press and hold the power button for 30 secs, release and wait for 5 secs, and turn the laptop on again. Laptop will boot with Balance mode on all laptops and with the default rgb wave on rgb models only.

2. Reboot

3. Enter BIOS → clear psp key and set restore default overclocking to enabled

4. Reboot

5. Check the CPU performance under load

Hopefully the issue is resolved!
