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

spacebar, main enter key, ctrl, shift, alt, numlock, f11, f3, a , s , d > 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 tap shift, numlock,alt,ctrl multible times on the external keyboard. takes time because i don't know what's the exact solution and have to try my luck.

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 still same problems.

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

any help? motherboard problem?
