Hi, pretty much new here, glad I can be part of this community. I'm new to repairing laptops motherboards (Only previous experience was repairing a Z690I STRIX with a broken trace on the memory slot, and it was a sloppy job but worked)
Bit of background: I'm not new replacing Laptop parts and doing general testing. Bought multiple laptops of the same model since it's easier to repair and got some that I can either switch parts and test.
ASUS STRIX GL703GE-IS74
Motherboard Model: DABKNBMB8D0 Rev D All of them
Issues (Each one on a separate board)
One has a LCD Backlight issue (I got the Board Diagram which I'm uploading right now). Starting to learn this skill, already done some soldering jobs but nothing small in size. I would like a bit of help on what to look since I already discarded the LCD and the LCD is working as it should.
So far 1 of the motherboards is working without issues, and I was able to read the BIOS Information with the RT809F Programmer successfully. I believe the issue is with the bios on most of these boards (I think at least 2 or 3) For Example 1 of the laptops will boot into BIOS but won't boot into any storage unit. I tried to use the RT809F with a SOIC-8 Clip to read, backup and write the BIOS chip with the BIOS from the good motherboard but It fails to program the chip. I think It fails on all of them on the verification process. I'm thinking I should desolder the chip. What are your thoughts on this?
Edit: I also forgot to mention if the small Windbond chip on the bottom right is the BIOS Chip. I believe that's the one but I might be mistaken.
