Hi I shut down my laptop and when I went to start it a few day later it would not start. When I push the power button i can hear the hard drive spinning up and then a beep and it shuts off. It will then keep trying to start over and over again until i hold the power button for about 15 seconds. then it will stop. No lights come on and the screen stays black. I cannot remove the battery because it does not have one that can be removed. I did not change anything to the system or load anything new. I run a full time viruses scan protection and have not had any problems since i purchased the computer a year ago. I unplug the unit and made sure everything was unplugged such as my mouse. I checked and made sure there were no disks in the disk drive. Now what should I do?
Thanks in advance

First:- Turn off the computer, press and hold the PWR button for 4 seconds.
Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.
Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat
AND/OR - Power on your PC, press Esc (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).
