I have an Inspiron 14Z which won't turn on anymore, which I suspect is because it shut off when I accidently disconnected the power supply from ac adapter. This happened a couple of times in the past, and I could always turn it back on by reconnecting the ac adapter to the power socket. However the last time it happened it wouldn't turn on at all, even though the light on the ac adapater was on. I also tried with just the battery. I also did troubleshooting by disconnecting ac adaptor and battery and holding the start button for 20 seconds, then reconnecting ac adaptor and pressing the start button. But it still does not turn on.
Do I need to get a motherboard replacement and how much would it cost(my laptop is out of warranty)? And does this mean I have lost all my data (or RAM?) on the laptop?
Please help~!
