Hi,
i have an ibm thinkpad type 2628 (pentirum III). the charger was lost, and my son found a charger that he thought would work. while i was at work, he plugged a sysco router charger (48 volts) into the laptop. now the laptop won't turn on. my question is, would the pc just shut off when a power current larger than allowed, is plugged in? (just like when it gets too hot, it shuts off). is there a fuse or reset or something? or is this thing just fried? there must be a way to fix this. or is there?
thanks.

Hi
Not good news. At best the power controller card is fried, at worst the whole motherboard went with it. You need a specialist repair shop - if you are in UK I can let you have a name.

thanks albert,
where would this power controler be? i mean the pc didn't smell like burned or anything.
p.s. in in usa

The power regulator board will most likely be by the power socket, but as AlbertLionheart said, you will need a specialist to test the extent of the damage.
