F7 Screen keeps Black

[Marcel]

Hi,

I’ve a problem with my Teclast F7.

At first everything was fine except a weird sound from the speakers while charging.

 

But now the screen keeps black if I press the Power Button,

only the left blue LED lights up.

Here is a video where you can see the Problem: Video

Looks like some sort of problem with the BIOS, the same thing happened to me after a BIOS update on my Chuwi 12.3. Your best bet would be to open the laptop and disconnect the battery for a while, to force the BIOS to reset. Then plug everything back in and turn the laptop on.

Thanks that worked fine.
