How to Reset bios? my screen suddenly turned black (solved)

Hi,
I was playing with my bios (bad idea), and i have disabled the graphic card by my stupidity
So, i have a black screen each boot
I doesn’t found any battery on motherboard to clear CMOS… (or any pin to shut clrcmos)
Can you explain how to clear CMOS to reset bios to default ?
Or in blind mode, how to reinit bios ?
eg : F7 on boot, wait 15 sec, 5 right pad, F9, enter, enter… => PC reboot, but no graphic card
So Default by F9 doesnt help in my case…
Long press (30 sec) on power button, 3xbutton …
Long press (wait), plug off and on cable…
A lot of other try doest reset nothing… black screen…

Or may be guide per combined keyboard in Bios to reenabled graphic card ?
In blind mode not easy, but why not…

I just found the solution to have my graphic card updated with latest 2024 driver (with Adrenalin panel), so it’s so stupid to have soft brick just with an option in bios (graphic card disabled)
I have invest a lot in memory and emmc ssd … so i want to play a lot with my chuwi higame

Thx a lot for your help !!

Ok, i answer myself

F9 and F10 are not to “force default” and “save & exit”… It’s F3 and F4

So, in blind mode (no screen) :

  • Power on
  • Wait 4 sec and tap tap tap “Del” key
  • Wait 15 sec
  • F3 and Enter
  • F4 and Enter

Pc reboot… and screen switch on

Thx !!
