I have a Gateway laptop, only about two years old, it was fine a couple of days ago and when I tried to start it last night, while it was plugged into a power source it would start running the fan and the power button would light up but only lasted seven seconds before everything shut off again, this repeated over and over with about three seconds in between. I thought maybe the battery he just needed to charge so I let it do so overnight but today I'm having the same issue. I have searched several forums looking for an answer to this but couldn't find anything that it worked
