Hello,

I was using my external universal battery on my laptop (19v), but then
I decided to work on my other laptop which takes 16v and I forgot to
switch the external battery to low voltage.

I didn't notice anything until the battery in the laptop starting going
dead, not receiving any power from the external one.

I tried plugging the ac adapter in, but now it won't charge.

The laptop is a fujitsu lifebook p2110.

I tried to open the laptop to see if anything looked fried, but it
seems like there's a trick to open it.

Anyone have any ideas on how to fix this? could it be just a fuse?

Thanks for your help.

Josh
