This may be a sign that your battery is depleted and needs to be charged, or you may have an old battery that requires replacement. Charge your laptop fully and see if it turns on, if not consider testing your battery's performance and replacing it.

The problem might be located in your hard drive. There are a few probable causes for this including:
- Your computer is bumped or jostled while it is running
- The electric motor which allows the platter to spin fails due to bad bearings or other components
- The filter on your air intake gets too clogged or the filter isn't working properly
- Extreme heat while running causes the electronic circuit board to fail
- There is a sudden power failure while the disk is writing
Try troubleshooting your hard drive for these possible causes and refer to the repair guide to help fix this issue.

The power jack may need to be replaced, or the AC Adapter may need to be replaced. Use a multimeter to confirm that the power output from the AC Adapter matches what you see on the multimeter. If it matches, the by process of elimination, you can move on to the next possible cause.
After removing the motherboard, examine the power jack solder points, and the internal power jack for damage to the center pin. If you confirm the solder points are loose or broken; or the female receptacle area of the power jack is damaged, then replace the power jack.
