Three months ago my battery got completely drained out. So I started using my laptop plugged in with the battery still attached. About a month ago I was working when out of no where my laptop froze. So i attempted a hard restart. On restart laptop was directed to BIOS. The keyboard and the touchpad didn't work but externally connected devices worked ok. So i kept restarting multiple times and the windows would boot eventually. After 5-10 min of login the keyboard and touchpad would stop working. No issues with externally connected devices. I took my laptop to the service center but they had no clue. This went on for a week. I finally decided to remove the battery and start using . Just like that the problem disappeared immediately. I was using Windows 8 all this time. Now that everything was working well I upgraded to Windows 10. It worked well for two weeks or so and now the issue is back. No body has a clue what the problem is . Please help
