Can someone help? My predator helios 300 PH315-52 suddenly auto type spamming even at bios

It is like clicking a key in my keyboard repeatedly without me clicking anything

Sounds like the keyboard connector on the mainboard needs to be re-seated a few times to help clean its contacts. Sometimes happens during hot and humid weather when the connections become intermittent and results in multiple or automatic keystrokes . Unfortunately, 10 screws and bottom cover must be removed along with the battery to access the keyboard connector which is also covered with sticky tape.

I tried reseating the keyboard connector as you said but still did not help. Do you have other solutions?

I tried turning on my laptop and close the lid to make it sleep, then I removed the keyboard connector, the problem is not showing anymore using an external keyboard but the internal keyboard should be disconnected. What can i do?

After removing the keyboard connector and using an external keyboard, it is not auto typing anymore. I am not sure if the problem is with the internal keyboard itself or maybe in the connector

I still think the connector is the problem. Lightly moisten a cotton swab or Q-tip  with rubbing alcohol. Gently rub to clean the contacts on the keyboard ribbon cable and the mainboard connector. Wipe dry with clean cloth. Then re-insert connector and test again.
