I need a way to reset BIOS settings to factory defaults

I tried to reinstall the OS from USB and I accidentally set ‘OS select’ to ‘Linux’ in BIOS. Now my laptop does not boot. When I turn it on, the screen stays black, the CHUWI logo does not appear. The power LED and keyboard backlight come on, but that’s all that happens.

Any help would be appreciated.

Please contact aftersale@chuwi.com.

I have the same problem. Changed ‘OS select’ to ‘Linux’. Now the screen stays black after booting up. Also sent an email to aftersale. Creating a ticket on https://www.chuwi.com/support/ticket.html did not work for me (HTTP errors 503 and 403).

I suspect the BIOS setting(s) can still be reset by “blind-typing” on the keyboard. See for example https://techtablets.com/forum/topic/lapbook-air-uefibios-sequence-to-restore-defaults/#post-141645.

REQUEST: Can someone (maybe from Chuwi?) with a Lapbook Pro provide a similar sequence of key-presses to:

  • either reset all the BIOS settings
  • or change the ‘OS select’ from ‘Linux’ back to ‘Windows’?

Thanks in advance.
