The keyboard is messed up.

[AhmedouviX]

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

8 > up arrow

4 > left arrow

. > delete

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.

any help? motherboard problem?

Ran a test on HP Pc hardware diagnostics UEFI and got that failure id

Hello @AhmedouviX,

Thank you for returning to the HP Forums!

I read your post about the keyboard not working correctly on your ENVY 15-3012tx Notebook and wanted to reach out to you.

Since you mentioned the issue started after cleaning the system, you may want to review the recommendations in the document for Cleaning your Notebook.

From what you described, you may have a stuck key. You can start troubleshooting the keyboard with this document.

Based on the fact that you received a hardware failure code, there may be one or more parts which are failing. Which specific test did you run that came back with that result?

You may also want to refer to the service manual (page 95) if you want to remove/replace the keyboard.

Please let me know if this information helps you resolve the issue by marking this post as Accept as Solution, this will help others easily find the information they may be looking for.  Also, clicking the Thumbs up below is a great way to say thanks!
