|I boot up my laptop to find that the LED on the power button would turn on for a few seconds (10 seconds) and then shut off. No beep, no post, nothing. I attempted to boot up in various ways - with battery only, with AC adapter only, with both - no luck, I would get the same result each time.|
I tested the AC adapter with my multimeter and it seems to be functioning properly, so I am starting to presume something is wrong with the power converter on the motherboard.
If anyone has any suggestions !
