Re: Asus X555L backlight shuts off when on battery
I had the same problem with an Asus X555L notebook- it works fine on AC, but the backlight turns off when I disconnect AC, even in the BIOS.
I updated BIOS, etc, then read about the back light coil on the PCB attached to the actual panel, on this or a similar post, on this forum.
I didn't have the correct replacement coils, and I figured they should either work or not work, so I ended up putting flux over the area/chips around the coil, then heated the whole area - being careful to cover plastic parts and other heat sensitive parts first with thick foil.
Tested - and its working fine so far.
I suspect poor solder caused the issue.

Re: Asus X555L backlight shuts off when on battery
Hi guys ! I am new here and i have a X553M that hase the same problem.
I have a donnor laptop (X553M) with a crack screen but i was wondering if swapping the PCB from the donnor screen to the main laptop screen could solve the problem ?
Is it easily doable ?
Thanks !
