Laptop does not turn on. To do something?

With a good, rather expensive laptop, I connected a defective device for charging. Suddenly the latop went out. KA what do not load does nothing.

It is best to go to the specialist shop before you start disassembling it as you would lose the guarantee.

But I had the same problem with mine, but the store people were able to start it again.

That was probably a short circuit in the laptop, because only the device helps

give repair.

Thanks
