Hi again Francisco, Sorry again for the delay .. It's quite busy period for me now. Before I can test anything for you, shouldn't my pc be functional ? I just replaced the BIOS chip as we suspected a corrupt BIOS is the cause with a blank chip I flashed myself (still waiting for the pre-flashed I ordered in Taiwan) . I believe the flashing went OK, did some tests. BUT ... it doesn't change anything. When I press the power button, the power LED goes on, ventilator starts spinning, processors get warm (not excessive but warm) but nothing happens. No beep, nothing on screen (also not with external...

Hi, sorry for the delay as I was out of home for a few days. Can you make a picture of that chip on the board ? Can you explain diode mode, you mean like for testing a diode ?...

Just ordered the tools ! :-)

I'm used to flashing chips like Arduino compatible, ESPressif, Atmel ... but never flashed a BIOS yet and not sure if I have the right tools for it.

Hi Francisco, no problem but you will have to give me precise instructions what/where to measure. Also please note that currently my mainboard is not functional. It powers up but nothing on screen. I suspect the BIOS is corrupt and I am waiting on a new BIOS chip I ordered in Taiwan.

UPDATE !!!! I found it ! It was on the other side of the PCB and as it was still mounted in the laptop I didn't see it ! THANK YOU SO MUCH Francisco !!!!!

Hi Francisco ! Really appreciate your efforts to help me out ! If you need my help, let me know ! This is a picture of the area around the HDMI connector. The board revision is : MODEL G7EL - DAG7ELMBAC0 REV: C

Thank you so much but are you sure we have the same mainboard as I cannot seem to locate this part of the PCB ?

That's the issue .. I have the part but not the location on the PCB ! The part is a 3 PIN SMD with reference X32A. I added a picture.

Hi, hope you have solved your issue ? I have the same laptop/mainboard and I am desperate for high resolution pictures of the mainboard front & back because I have a loose 3 PIN SMD component (probably voltage regulator) and looking for where it is missing. Could you provide me with some pictures please ? Big thanks !
