Pushing the power button has no effect. I do have one light on on the front of the computer, it's white. I've tried removing the battery, disconnecting the ac and holding down the power button for 60 seconds. When I installed the battery and connected the ac all three lights on the front lit up and the screen lit up for a couple of seconds then went out it did this without me pushing the power button. I have checked the voltage of the power cord and it is fine(19v). I also checked the bios battery and it is fine (3v). The hard drive and fan don't power on. I don't think it's a black screen problem It seems more like it just doesn't power on. Does this model have a magnetic switch that activates when the lid is opened? Thank you for any help.
