Battery has no charge
If the computer does not turn on, most likely the battery needs to be charged. To charge the battery, plug the charging cable into an electrical outlet, then plug the other end into the round power-adapter port on the left hand side of the computer. The light on the charging cable should turn on. Wait 5 to 10 minutes to allow the computer to build up charge, and then try to power on the computer again.
Faulty charging cable
If the computer still does not power on after you plug in the charging cable and wait for the computer to accumulate charge, then the charging cable may be faulty. If the light on the charging cable does not turn on when it is plugged in, then the charging cable is faulty. You will need to purchase a new charging cable.
Power circuit has built up a static charge
If you have determined that you charging cable is working, but the computer still does not power on, there could be a static charge build up in the power circuit. To remove this static charge, unplug the charging cable and remove the battery using this guide: [http://|see battery replacement guide]. Once you have unplugged the charging cable and removed the battery, hold the power button down for 30 seconds to dissipate the static charge. Then, put the battery back in by following the battery replacement guide steps in reverse order, plug in the charging cable, and attempt to turn the computer on again. You should be successful.

Laptop locks up or shows error message
The computer displays an error message and will not return to home screen.
