This is about a Presario 2500, given back to me by my daughter after using since March 2004. Battery is dead and she has lost the AC adaptor. I bought a new AC Adaptor and tried to boot it. No lights or any sign of life and I also tried pushing the reset button on the bottom. Is there any fuse or something gone bad? It had 2-year warrenty that ran out in March this year. I prefer to fix it if does not cost a lot. Please help me with some advice to get it fixed. Thanks.
