i have my Acer 1640z,,, lately nagkaroon ako ng problem sa touchpad ko. it was happened nung nag-copy ako ng file from laptop to mobile and it was not plug sa AC (kuryente). while i was transferring a file from laptop to cp, suddenly may nagpop up na message, nakalimutan ko yung msg. but something concerns with the battery... taz nung i close ko yung msg. yung touchpad ayaw naman ng gumana... i tried to plugged sa AC taz parang nag hang yung touchpad ko... then i have to re-start,,, doon na nag start na ayaw gumana touchpad... i tried to reformat and re-install xp sp2 pero eto napansin ko... everytime its not plug sa AC the touchpad works fine pero pag ikakabit ko na yung adapter nya sa AC saka ayaw gumana...
ano po sa tingin nyo may problema dito... at ano ang solution... i just need your thoughts.. di ko ma figure out kasi problema neto eh...
salamat po sa inyo...

seems like you are loosing power somewhere in the system so malamang hardware nga. Maybe it is shorting somewhere. Hindi yan madadala sa re-installation of drivers or OS or even formatting.
