I have a Compaq Presario 2500. While I was using it yesterday my mom came in and asked me to run over to the farmstand and get an apple pie for after dinner. I went out, wasn't gone for more than 25 minutes, and came back to find that the laptop I left on was now turned off. I couldn't get it back on. First I thought it was something funny with the power cable. I'm using a Targus cable instead of the one the laptop came with. I noticed the blue light on the Targus cable wasn't going on when I plugged it in again. Then I realized, though, that if I unplugged the cable on the laptop end and just plugged it in at the wall socket the blue light does come on but as soon as I plug it in to the laptop the light goes out. This just seems like a funky cable problem but here's what gets me worried: the battery in the laptop still shows it is powered but it is still completely dead when I press the power button. What kind of problem am I looking at here? I'm not sure if I should investigate the cable or if some kind of glitch screwed up my whole laptop in that 25 minutes of time I was out getting the pie. I have no clue- HELP!
