Acer Aspire A315-53G || Keypad is not working properly on my acer aspire laptop.

Muzaik

while working I pressed ''1", it did not type after multiple presses the system went off. I restarted now my pin had 1 therefore as I pressed 1 it went off or automatically or showed the pin is incorrect before I could press enter. somehow I managed to log in, but I noticed multiple keys had malfunction like I pressed 1 from the top left key (not from the num pad) and it turned aeroplane mode, the shift key on the left-hand side would also turn the system off. and many more keys were doing weird things. 

can anyone help me, what is the exact issue? I have rebooted the system multiple times but the problem persists.

model: Aspire A315-53G.

Shut down Windows normally. Turn the machine back on and immediately tap F2 to enter the BIOS menu. In the BIOS Main tab change the FN key behavior option from media to function. Then press F10 to save settings and exit the BIOS menu.

If the problem persist after trying @JackE's method, then it is time to change the keyboard.

I have the experience that a faulty keyboard almost forced me to have a half filled HDD reformatted ( have WD HDD locking software, that will only allow 5 failed attempts during HDD login, or HDD will be reformatted )
