Hi fellows. I'm trying to revive my mom's E1-571 ( LA-7912p) i5 and HD4000 Full specs here
Laptop doesn't have visible or known issues like liquid damage or overheating.
One evening shut down went normal and in the morning:
Device won't post/boot.
-Disassembled and made hard resset.
-When press power on after electrical discharging,
device turn fan on, power LED light up, CD rom make check noises, all that for 3 seconds , nothing on screen no even backlit.
If i press power button again ONLY power led light up for 3-5secs and goes off again.
If remove power supply and try again, first scenario once and, keeps same.
Flashed both bios chips, no difference!
Any suggestions and help will be appreciated. I have schematics of motherboard. What to look for?
