Laptop : Sony Vaio
Model : VPCEH28FN
Ram : 4GB
Intel Core I5-2430 processor
Hard Disk 500GB
Graphic Card: NVIDIA GeForce 512MB

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

This is your clue. The keyboard and touchpad electronics are integrated into the motherboard BIOS itself, there is nothing to "fix". On many computers, when booted, there is a "beep" when first turned on. That is the keyboard recognition beep coming from the POST screen (the BIOS). They are loaded from the BIOS and have nothing to do with your operating system, although they can be slightly configured for button usage depending on which OS and BIOS your manufacturer included.

First, your laptop is nearing end of life, so be aware. If you have valuable data on it, I strongly suggest that you back it up immediately.

Here are a couple of things that you can try, but no guarantees that it will "fix" the problem permanently.

> You battery needs to be replaced. Every laptop owner knows that eventually the battery will not hold a charge anymore. I am surprised that your laptop even ran with the battery removed. If that will help the problem is anybody's guess.

> You posted that the external USB ports worked ok, so try plugging in a USB mouse and USB keyboard. That may or may not work.

> If you can access the BIOS screen, try setting the CMOS back to factor default (if Sony included that option, you never know with these manufacturers, especially Sony) just in case messing with your laptop corrupted some settings.

Other than that, there isn't anything else to try.
