What to do if not turn on laptop?

Took an old laptop, turned it on via the adapter (no battery), some time the laptop was on, tossed the files from it, then the copy was successful and pulled out a flash drive, and laptop in 5 minutes blacked out, the screen of the laptop is broken, sat through the VGA controller attempts to turn on the laptop to anything not led, the led which shows that the charge is not burning, maybe the adapter is broken? The laptop is Toshiba Sattelite a100-237

maybe the adapter is broken
Maybe, maybe the laptop is broken.
Carry in service.
What's the point in guessing?

Take a voltmeter and check the voltage on the output connector of the power supply.
