Have you ever called a computer repair store saying “my computer turns on and off by itself”? This is a problem that can be so frustrating, especially when you’re in the middle of working on something important. If this happens to you, check for the obvious problems before reading this guide. How are the connections between the power supply and the computer? There could be a connection problem in the power line or the computer battery might be too worn out to charge itself, resulting in a computer turning off quickly after it was turned on.
What’s the problem?
It could be that the power supply is incompatible with your computer. If you use an extension cord too long or are using a 220V adaptor for a 110V outlet, there is a chance that little to no power is actually reaching your computer — try a new power outlet.
Check the power button on your computer — press it to see how the computer reacts to you pressing the button. If the computer turns off, try to turn on the computer again by pressing the button to see how long it takes for the computer to turn on again. A longer lag time between power generally indicates a more extensive problem.
Try holding the power button when turning on the computer to see if it changes anything. Sometimes the difficulties in the power connection originate from the problems with the power button.
Depending on the environment in which you operate/store your computer, there may have been damage to your computer that is too extensive for you to fix. Liquid (rain, drink, etc.) may have seeped into your computer and short-circuited your computer, resulting in a computer that cannot handle power.
Or it may be that frequent and large variations of temperature (you store your laptop in a car during summer, frequent heating and cooling, etc.) may have damaged your computer as well. For these problems, it is encouraged to seek professional help.
If the computer your are having problems with is a new computer and you are sure that it is not damaged, the problem may be caused by the misconfiguration of the settings in your computer. Consult a professional.
