Acer nitro 5 N20C1 - charge but no boot

[nosfay]

Hello, something else to check or EC flash is my last bullet?

I dont think flashing the EC chip will solve your problem. have you checked the RTCRST#/SRTCRST# is present or not?

Both PCH_RTCRST# and PCH_SRTCRST# are present at 3v

If 3.3V/5V/1.8V/1.0V ALW is present in standby then proceed to flash the main bios as well as EC.

Hello, I'm back with this laptop, I decided to dump the EC but before, just tried to boot again, and the keyboard lighted up and fans spinned, and no picture. CPU, GPU and PCH was warm.
I've flashed back original BIOS, but cannot boot (sometimes not at all, sometimes only keyboard light and fan).
Power on doesn't work with keyboard, I have to use a tweezer on the connector.
If the keyboard is connected, I cannot power on, even with tweezer.

And finally, after charging the battery for a while and booting withtout the keybord (I only let backlight ribbon connecte), I've got a picture !




I will try my old broken keyboard, but this is really weird.

Faulty powerbutton on keyboard. Just replace the keybaord

Yes, and I've got bad luck with theses keyboards:

1st one (the original) : was working but lot of keys was destroyed by last owner
2nd one (refurbished) : not working at all
3rd one (refurbished) : worked maybe 30mn, then I started having issues and finally broke

The 3rd one was the worst as the laptop cannot boot at all when plugged in, even when shorting power button.

Perhaps you're sourcing the keyboard from some unleiable place. have replaced a lots of gaming keyboards on MSI/ASUS/ACER without any issues.

I've got the new keyboard, and this time it works, thanks for your help
