The laptop's keyboard is messed up.

My keyboard is scrambled and messed up. keys do wrong functions and some keys don't even work.

yesterday i cleaned the keyboard with a tissue paper with very slight amount of water on it then the keyboard messed up and some keys typed duplicated characters, for example when i press 1 it types 2 and 3.

not my first time cleaning and i even used more hard methods before with no problem.

did many solutions on google and now some keys doesn't work and others types wrong characters even when i use external keyboard.

for example,

on top number bar

1 > !

2 > @

3 > #

on numpad

numlock doesn't work and have to use external keyboard to enable it

8 > up arrow

4 > left arrow

. > delete

9 > doesn't work

5 & . > types .5 when numlock is off

3 > 2

spacebar, main enter key, ctrl, shift, alt, numlock, f11, f3, a , s , d , f ,z,x,c,v,j,k,l > not working on the laptop keyboard but work on the external keyboard

the wrong characters thing happens on the external keyboard too.

to fix the wrong characters i have to keep tapping on shift key on the external keyboard or on screen keyboard

this method doesn't fix the keys that don't work on the laptop

i cleaned every key on the keyboard to make sure there is nothing stuck under any key.

tried on bios and Ubuntu live usb still same problems.

i also noticed that the keys that doesn't work are registering clicks but doesn't show any thing

also after boot i notice on on screen keyboard that shift & numlock are being clicked

any idea what is happening> motherboard problem ?
