Dear Chuwi team, I wanted to ask you to fix the BIOS (Chuwi gemibook 13). The reason is the possible elimination of high-frequency noise. ([Chuwi Gemibook makes a high frequencies noise](https://forum.chuwi.com/t/chuwi-gemibook-makes-a-high-frequencies-noise/32623))  
The high-frequency noise disappears when the GOP brightness percentage is selected - 255% (the value range assumes such a value 0-255, but this setting (255) is not saved and the BIOS is loaded with the previous settings (240). Therefore, after restarting the BIOS, the high-frequency noise occurs again.
