Laptop not powering up

[Sushmit_1]

I accidently inserted my phone's charger in my laptop's USB port from the charging end. The power suddenly went out and it isn't powering up now. The laptop was plugged in and charging and the phone's charger was switched on too. What to do?

Was your phone being charged via a USB connection or did you stick the plug into the USB?

No the phone's charger was connected to the main power supply. I touched it from the free end.
