[tommy97]

Hi,

I've got a problem with laptop Asus ROG GA503R, laptop power on (it does take a while) show asus logo and then it stuck on the black screen noticed that laptop goes to windows. I've tried new LCD, no difference, I can go to BIOS, laptop would stay on can change options etc., tired boot it externally with disconnected LCD and it only display on BIOS, attempt to boot to Linux, same problem.

I would provide with board model tommorow.

Hi everyone,

Have a ASUS GA503RS, it turns on, but after showing the logo the screen stays black. :-/
No success trying another screen, no external image either.

So after reading this thread and seeing similar issues being fixed with a BIOS flash, I would give this a try.

Have a CH341 programmer and can solder pretty well.

Details on the device:
ASUS GA503RS-LN055W

The BIOS chip is a Winbond 74M25JWEIO, my research shows it is a 1,8V powered chip, 256Mbit in size.
My NeoProgrammer software has a W25Q256JW chip with 1,8V listed, I assume I can use those settings
to read and write.

Thanks in advance for any help.

Post moved to RS thread from RM . Yes, you can choose the winbond chip manually. Post your backup here

OK, it took me a while but here is the dumped and verified BIOS. (Details in post #7 of this thread).
