When I was shutting down my laptop the other day, it cut off rather quickly instead of doing the whole shutdown routine. The next day, I couldn't get it to come on. The battery in it is extremely week and when I noticed the little green light on the A/C adapter wasn't on, I thought that maybe the A/C adapter had gone bad and because the PC was plugged in but not receiving power, it didn't give me the low battery warning and just lost all power and shut down. I ordered a new A/C adapter which arrived today. When I plugged everything in, the laptop still won't turn on. A couple of questions here: If the battery is very week to dead, would the power from the A/C adapter alone run the PC? Any other suggestions on what this might be? Also, if I can't restart this laptop, is there any way to get the data from the hard drive or is it lost?
