Laptop keyboard constantly stops working

[buddhapipe]

Laptop Model: GL503GE

Here is a bullet point summary of the issue:
- Keyboard (and LED lights) stops working completely and doesn't show in Device Manager
- An external keyboard plugged in to the USB port will work (and shows up in Device Manager)
- I am typically able to fix my laptop keyboard through a combination of BIOS driver update, HotFix driver update or other drivers (to be honest, I am unsure which combination of driver works, it seems to be different every time)
- A day or two after the fix, the LED lights stop working
- About a month later, the keyboard stops working
- I reinstall drivers and the cycle starts all over again

I have tried sending in my laptop for repair, but all they did was update the drivers. Again, it worked for a month or two before the problem reoccurred. I tried speaking with customer service, but unfortunately it never goes anywhere.

Has anyone found a permanent solution to this problem? I'm tired of randomly updating drivers every couple of months because my keyboard suddenly stops working. I would even settle for a bit of clarity on the drivers I should be using.

Thank you.
