Sometimes electrical components needs to have all power sources removed and reintroduced to work properly. Try performing a hard reset first, if it doesn't work then we'll move to the next step in diagnosing whether it's the hard drive or the motherboard/connection.
To Perform A Hard Reset
- Shut down the computer by going to the Start menu and selecting shut down. (If you have no display, hold the power button down for 5 seconds)
- Disconnect the AC Adapter from the notebook.
- Remove the battery from the bottom of the notebook. There will be a switch/button to eject the battery.
- Wait at least 1 minute with all power sources disconnected.
- Re-insert the battery and reconnect the AC Adapter and then attempt to power on the notebook.

Is the notebook still under warranty?
As a further test, try the following.
Using another PC, follow the procedure on the link below to create a bootable Ubuntu CD and follow the steps in Part 3 to 'Try it' to see if this OS will run on your notebook. The 'Try it' option runs the OS from the CD without the need to install on your HDD. If this runs Ok ( it will be slow running from a CD ), this would tend to confirm that the problem is with the HDD.
