Hi,
i cleaned my keyboard with a slightly wet antibacterial wipe the keyboard has now gone haywire. Several keys work fine with no problem others when you press them type different characters for example the g key types ‘4gv’ and m types ‘tmh’ the backspace key enlarges the screen. I have added an external keyboard which works fine
Ist dies eine gute Frage?

Hi,
The constituent parts of anti bacterial wipes usually consists of a disinfectant and approx. 70% Isopropyl Alcohol. (check the packaging label to find out what’s in the ones that you used)
Did you wipe the keyboard whilst the laptop was on or start the laptop before the keyboard had completely dried?
Isopropyl Alcohol is electrically conductive but evaporates quickly and doesn’t leave a conductive residue but the type of disinfectant used in the anti bacterial wipes may be extremely conductive to electricity and leave a residue and because of this, cleaning the keyboard may have damaged the components in the keyboard by providing electrical paths that were not in the design of the keyboard circuits if the laptop was on during the cleaning process or turned onto too soon afterwards.
You may have to replace the top cover/keyboard as attempting to repair a liquid damaged keyboard can result in more problems than what you had.
Replacing the keyboard in your model laptop is not the easiest to do as you have to completely dis-assemble the laptop to get to it, as it is an integral part of the top cover.
Here’s a link to the service manual for your laptop.
On p.75 it says : “The top cover/keyboard part remains after all other spare parts have been removed”.
Also on p.75-76 you’ll find the part numbers for all the country specific top cover/keyboard variants available for your model.
If you search online using the appropriate to your model part number only you’ll get results for suppliers of the part.
Usually you should be able to find the part number stamped on the underside of the keyboard/top cover if you wish to verify that you are ordering the correct replacement part.

Hi @christopherwat
If the keyboard suffered liquid damage usually drying it out doesn't fix the problem of the corrosion caused by the impurities in the liquid. The corrosion is ongoing until it has been properly cleaned off
The easiest way is to replace the keyboard.
You can try disassembling the keyboard and cleaning away any corrosion with Isopropyl Alcohol 99%+ (available at electronics parts stores) but this may not be easy or even fix the problem if some components have also been damaged.
What is the make and model number of the laptop?

Hi Elizabeth,
This smells like a keyboard shortcut after cleaning your keyboard. :-)
Can you test the following keyboard shortcut: CTRL+ALT GR
War diese Antwort hilfreich?
What is ALT GR?
This is the key at the bottom right just after the space bar.
On an Apple this is a Command key. So what does hitting the Control and Command keys show you?
Indeed, on an Apple the shortcut will not work.
But in the original question, we are under a Windows system and not iOS.
If you have a problem with your Mac, I invite you to ask a new question directly.
On this machine what does hitting the Control and Alt keys show you?

We agree, when you type on the letter "m" it makes you "tmh"? What about the backspace to enlarge the screen? What is the Windows 7/10 or Linux operating system?

It’s windows 10 the other keys work fine they type he correct characters but also do other things like open new browsers etc depends on which key you press

Maybe it's the narrator who's activated then.
Press the Windows logo key + Ctrl + Enter on your keyboard to disable it (if it is enabled, you can make the shortcut to disable it again).
