system is out of warranty was working perfect last night now certain keys wont work .the netook is well looked after and was never in a fall any ideas? tried devcie manager and updating drivers most keys are working just about 4 that dont and 4 example if i press I a 5 is inputted on screen its an emachine em350 i have connected a usb keyboard and using this everything seems fine within the system
try uninstalling the emachine keyboard from device manager & scan for hardware changes so windows can find keyboard & load it's driver.
