Wrong Power Adpt Plugged Into Laptop, Now It Is Dead

The wrong Laptop adapter was plugged into my laptop by my grandson, now the laptop is dead. Is my motherboard fried, or is everything fried, meaning memory, hard drive, cd-rom, etc. It is an IBM A30. I tried the right adapter on it and nothing happens. I did put some extra memory I had in it and it is still dead. Any advice would be appreciated. I don't know weather to take to shop or buy new laptop. Thanks

 

What are the voltage specs of both adapters?
That might give us a clue, but I don't like your chances. :cry Bazza

There may be an inbuilt fuse to cover these sort of possibilities, and protect the innards.

Maybe get a shop to check it out before outlaying $$$ for a new laptop. Bazza
