What's new

Schematics Dell G15 5520 - HDK50 LA-L659P REV1.0

My friend, don´t work, It's completely dead. Can you help me? I already tried the new .bin file you sent me, and it still won't turn on. It has all the correct voltages. It's a BIOS issue.

I reprogrammed the memory with the BIOS you sent me (clssss (2).bin), and it's still dead; nothing turns on. I reprogrammed it again with the original BIOS (the one I sent you in the first message), and the laptop turns on, but there's no video output. Can you help me?

Excuse me, friend. The thing is, if I install the original BIOS (https://vinafix.com/attachments/w25q256fv-wson8-8x6-original-bin.466190/), the keyboard lights up when I press the power button, and the battery charging LED comes on, but the fans don't start, and there's no video output. So, there's definitely a problem with the BIOS. It was after updating it under Windows that it prompted for the update. But with the edited BIOS you sent me, nothing happens. I press the power button, and nothing turns on. I also tried the one linked at the beginning of this post, and nothing happens either. It's clearly a BIOS issue. That's why I'm asking for your help.
