I have a HP Laptop with Windows Home Edition. Not sure what happened, but the laptop does not boot. The power switch seems to be on, and the exhaust fan which is connected to the usb port works, which means there is power going in. But when I press the power button to start the laptop, nothing happens. Hope the experts can please suggest the fix for this. Maybe if I get pass the login screen, I will do a system restore. Thank u.
