I was given a inspiron 4000 laptop and it won't turn on. It will charge the battery but if you push the power button nothing happens. I took it all apart to make sure the motherboard wasn't damage any where and it looks find. I tried the cpu in a other laptop and it works and the memory works too. So a ruled those out. It won't turn on with battery or with it being plug in. The service tag is 7GNTK01. All i know is the guy i got it from told me he was typing on it and it shut off and wouldn't turn back on. Hope someone can help i am lost now.
