Hi Ppls

Working on a Dell G15 5520, motherboard LA-L655P.

No power no LEDs; Ive tried all the basic battery disconnect, bios reset (even though it felt pointless with no charge indicator)

There is power getting to the board as there is heat generating toward the centre of the board, which I am presuming is part of the charge controller;

I haven't ruled out a faulty power switch so, anyone have schematics and board view for g15 5520 p105f to find safe jump points would be great, then I can work from there; or maybe you have had this issue?...

Hello,
Dell G15 5520 LA-L659P that is giving me an LED code indicating "System BIOS Flash incomplete

I tried more than one file, but it gives the same problem
“For the first time, the logo of Dell appears for less than a second, then...giving me an LED code indicating "System BIOS Flash incomplete"

Tried to use the BIOS_IMG.rcv and the CTRL+ESC, not working, don't go to the recovery.

Can someone help me?

The original BIOS file is attached...
