I have a Fujitsu AH 564 laptop from 2014. All other things work perfectly fine. Except for one thing. KEYBOARD.

A few weeks ago, everything was very fine, until recently, my keyboard start pressing tab by itself, so many times. All I need to do is only pressing the up button and it will stop for a few seconds and start to do it again and again.

Everything has already been tried. Restarting, booting into the safe mode, virus scan, factory reset, driver update and reinstall, YES EVERYTHING. External Keyboard? well, it's a laptop, you cannot turn off the main laptop keyboard.

Edit : I bring it into a computer repair centre and they said the hardware is in good condition. After a few months waiting, windows released a new driver for the keyboard and everything gets back to normal.
