CHUWI LapBook Pro 8GB – I need a way to reset BIOS settings to factory defaults

[blackbox]

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.

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.

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.

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.

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?

For a way to reset the BIOS, see the original thread.

Can someone tell me if the bios is unlocked so you can disable power limit?

Looking to bye a lapbook pro 8gb…

Thanks /Martin

The BIOS is fully unlocked AFAIK. Power limit is set to 12 Watt. You can increase it up to 25 Watt.

Personally, I find the laptop fast enough on 12 Watt. Will increasing the power limit really make a lot of difference?
