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

[WillemW]

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?
