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?

Hi ahmedouvix,

It sounds like your keyboard has failed - probably due to water (or whatever you were cleaning off it) entering the keyboard. The fact that the external keyboard works to clear the fault sometimes also points (to me anyway) to the fault in the laptop keyboard which is still making the contacts needed for this fault to show up.

Before buying a new keyboard try removing the laptop keyboard and just using the external keyboard. This will require some sugery on your laptop - take it to a repair shop if you are not comfortable doing this yourself (or know anyone that will help you do this).
