Wrong charger burned out Dell computer

My daughter has laptop at college and she plugged in the wrong charger while she was using it.  Worked for a bit then fried it.  Won't work with the orginal charger or on battery.  What normally happens to the laptop when this happens?  Can anybody tell me about how much it would be to fix?

If you gave it a higher DC voltage input than it can handle there are really two options here:

1. You have burned one of the auto-fuses on the motherboard
2. You have burned the motherboard giving it the wrong voltage

Do you have the voltage specifications of the two adapters?
I have managed to damage one of my older laptops batteries by connecting a too weak power supply to it, it essentially wore out the battery.

Have you tried disconnecting the battery only running it on AC-power?

I have not tried just AC.  Will have her try that in a few.  
Thank you

Worth a shot as the batteries and loading chips have mechanisms that talk to each other.
On my old Acer Ferrari it made the internal PS2 connectors misbehave when the battery was broken, disconnecting the battery made the problem disappear.

The charging circuit is probably blown. There are a few models where just the charging board can be replaced but on most systems it requires a motherboard replacement. There is also a possibility if it sent a spike or surge when it fried other hardware may have been damaged.

jamietoner is most likely correct.  The solution is to remove the motherboard and replace it.  After the cost of a replacement motherboard and the cost of having a tech do the work is added up, it is probably more prudent to buy one of the budget laptops that are on sale every weekend at Best Buy or one of the office superstores, and migrate any irreplaceable data from the old disk drive to the new system.

She wasn't able to remove the battery to try AC straight.  I couldn't talk her into it over the phone.  She had to take it to a place to pull the info off of it because a paper was due.  It's a Dell XPS 15 on warranty extended.  I hope we can get it fixed on that.

If it was purchased on an AmEx or VISA card with extended warranty benefits, and Dell denies your warranty claim, you might try with your credit card company.

AmEx with extended warranty.  I know my Daughter too well! The place ordered her a new battery
Hope that warranty included accidental damage. Dell's standard warranty won't cover this type of incident.
