Hi, I got this laptop for free coz it doesn't work and I want to make it work again. It's a 400mhz G4 Mac with 128mb pc100, 10gb hd and dvd drive. It was my friends and I remember when it did work the battery was old and only lasted like a minute so you had to use it when plugged in to the wall and then it worked fine. For some reason now it just doesn't power on at all, I left it plugged in all night and in the morning it just didn't power on, I can press/hold in the button or whatever and it just won't turn on. I have tried taking the ram out and putting it back in although I knew that wouldn't stop it from powering on at all. Is there anything I could try? Thanks in advance.
