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.November 13, 2019 at 3:23 pm #182073
I have the same problem. Changed ‘OS select’ to ‘Linux’. Now the screen stays black after booting up.
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 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.November 16, 2019 at 11:14 am #182080MikeParticipant

I don’t have the Lapbook at hand, but AFAIK the sequence should be similar (if it works that is). F2: previous settings, F3:optimized, F4: save&exit. Hope it helps.November 16, 2019 at 7:33 pm #182083
Unfortunately, could not make it work. We would need more precise instructions (to reset all BIOS settings) for the Lapbook Pro: how to enter the BIOS, when to press Esc or Enter, etc. and when to press in combination with Fn.November 20, 2019 at 10:21 am #182092blackboxParticipant

I was not able to fix it, either.
Chuwi support told me to reflash BIOS. But I can’t even get to Boot Menu to boot from USB.
I asked them for a different solution. Now, they don’t answer any of my messages.
Has anyone disassembled it yet? Is there a CMOS battery to remove or any other way to reset settings?November 24, 2019 at 6:24 pm #182121
