HP Pavilion g6-1219sv keyboard problem: the kb types numbers and letters concurrently!

[MinimalTech]

Hi!

I am new to the forums and I have a problem with my notebook HP Pavilion g6-1219sv (product: A1Q32EA#B1A).

After of 1,5 year of correct functionality, the keyboard started a strange behavior:

1) When I press a letter button, the keyboard prints a letter + a number. For instance, if I type the letter 'q', then appears in the monitor the string "q3". So, if I want to write "Hello" it will be written as "H3e3l2l2o" in the output.

2) The up-down-left-right arrows keys seems like to be stucked (when i press the down arrow key, it's like the up arrow key is stucked somehow and i cant go down).

I thought that maybe there is a problem in Windows (any update, a faulty program, a virus) but the same behavior exists even in the HP Advanced System Diagnostics v3.7.1.0 when I pressing the F2 key at the start of booting (I can't go down to the list to select for example "BIOS Management")...

How can i fix this crazy problem? Where do you think this problem is due?

Thanks 😉

Keyboard controller is failing, time to replace the keyboard.

I forgot to write in my initial post that i have already replaced the native keyboard with a new one but the problem still exists...
