Hi there.
I have the very same problem. Got a Travelmate 2500, BIOS password is lost. I tried to contact Acer, but they want me to send it in (*#!!!##ers). I dismantled it completeley just to find, that the batteries are soldered in. SW5 is undocumented.
PLEASE tell me how to get rid of the BIOS pw. I tried downgrading it, but I guess there's some kind of BIOS backup somewhere, as that didn't change a thing.
please help
cheeeeeeerz
