I'm having problems with my laptop (HP Pavilion dv4 1428dx) the last thing I did was put it to sleep, then cameback and tried to wake it up but it would not start up. All the lights are on, but the screen is black and the only thing I hear is the fan moving. The caps lock and num lock keys have a blinking light, not really sure what that means. The power LED is on, the battery LED is on, but the hard drive LED is not on. This computer is almost 3 years old and I have never had a major problem like this until recently. If anyone has any solutions I would gladly appreciate them. 

 

Thank you for your time,
