Hi,
My laptop model a540LJ keyboard problema first started as when number key section of the keyboard is ON number 3 key is typed on its own. So i turned off that section. It worked for a while. Some times keyboard stops working whenever i uninstalled the keyboard driver and restarted the system it worked like that for few times. Two days back spacebar of the keyboard and letter k is not typing all other keys worked. When ever keyboard acts weirdly in device manager there will be an unknown device showing. So i uninstall the unknown device thing and will do the same thing all over again and it worked again for few times. Now keyboard stopped working altogether no unknown device showing on device manger but key board is not reponding. Normal keyboard driver is showing under keyboard section of device manager and it is updated. Nothing is spilled on laptop,keyboard .is this a hardware or software problem i dont have an external keyboard to check whether it works or not other than that what are the solutions to this thing. The laptop is few months old. The problem started recently.
Sorry for the long post
I am using windows 10 x64 on the system.
