My computer is switch to 110 V and accidentally it has been plugged into 220 V and it burns!is there any way to repair it?tnx!

If you're lucky, just the power supply is fried. If you could swap in a known good one, you might be able to tell, but there is the possibility that your computer could damage the new supply. I'd suggest finding a good independent computer repair technician for this.

Good luck,
