Laptop shut down by itself while working. Since then it is dead and doesn’t power up.

My Toshiba laptop shut down by itself while working. All light indicators were out. clicking the power button did not help. After few minutes, I pressed the power button, the laptop came on but shut down again after few moment. Since then it is dead and does not power up. Any idea what could be the problem?

Test the power adapter first. Plug the adapter into the laptop and check if the power LED lights up. If the LED is still off, most likely the adapter is bad. Here’s my guess. The power adapter died while you were working on the laptop. After that the laptop worked for a while until the battery got discharged and finally shut down. The laptop will not power up anymore because you have a dead adapter and empty battery. Find a voltmeter and test if the adapter puts out any power at all.
