How To Identify The Power Failure Function In A Laptop

When the computer is turned on, nothing happens. Sometimes this may coincide with a flashing light on the front of the computer or an indicator on the back of the PSU (if equipped).

The computer turns on for a couple of seconds and then turns right back off. While this can be a power supply issue, it may also indicate motherboard failures.

The computer is on for a while, but maybe while you're playing a game or using another application it just randomly turns off without warning. It might also display a blue screen of death.

When gaming is involved, one must realize that video cards these days require a lot of power and amperes to run correctly. When purchasing a PSU, be sure you have the wattage and amps needed for the equipment inside of your computer, especially the video cards.

press and hold the power button for 10 seconds. The system should shut down. Power the system back on to resume normal use.

Use the following steps to restart if the system does not shut down:

1. Disconnect the AC adapter.
2. Gently insert a paperclip in the battery reset hole on the bottom side of your ultrabook.
3. Reconnect the AC adapter, and resume normal use.
