Acer Aspire 5002wlmi laptop

[shawn3091]

the laptop does nothing when i press the power button with just the battery in, but if i plug it in the battery light flashes orange and it does nothing else, i do not see anything burnt on the mainboard. has anyone ever had this problem or have any idea where to begin to try to fix it, i am not afraid to replace components/solder, i have nothing to lose , schematic could be helpful i cant find one anywhere, id appreciate any help

anyone know how to test the voltage regulators on the board with a multimeter?

How about with NO battery, just AC adaptor?

same i press the power button and the battery light flashes about 8 times, and that is all it will do, i notice as soon as i press the power button ethernet lights light up for a second and then the battery light flashes, so i am thinking something on the board is not getting power that should be or a component is bad or shorted, but i cant seem to find anything

Remove the memory and see whether it beeps RAM error code

[Guest]

everything is removed from it except the cpu

anyone know where i can get a free schematic of the board?

Even if the service manual was available, it wouldn't include the schematic.
No laptop manuals include schematics, at least none that I've seen.

i have tested areas with a multimeter and it seems to be getting power everywhere, 3.3v, 5v and 18v at various places on the board, capacitors all look fine, so my guess is bad power ic, voltage regulator or sm fuse somewhere i have no idea
