Windows 10: Dell G15 Windows 11 - N, B, Spacebar keys not working intermittently. OS, BIOS, Drivers are...

Been using a Dell G15 5530 for more than one year. Very often the N, B, Spacebar keys stop working. Sometimes they work fine and sometimes they are totally insentitive to even hard press. OS, Drivers, BIOS are all up to date. On some occasions, these keys work in BIOS, sometimes they dont. Kindly help with a solution. Many Dell G15 users have been pointing out this issue on Online forums. Not sure if this is a hardware issue or software issue. I haven't tried using an external keyboard

Spacebar, Letters N and B and Arrow Keys Sometimes Not Working?

I use an external wired keyboard with my laptop which is connected to 2 external monitors. I recently went to lock my computer. Then I typed in my windows pin/password wrong multiple times. I had no idea how this happened. Now because of that, I had to restart my laptop. I could click on restart laptop and then restarted it. After this, I am on my bitlocker pin page. It showed incorrect bitlocker pin and I was confused why. Then I decided to type my bitlocker pin on the laptop keyboard and it worked. Then when it went to the windows log in screen where you have to enter your windows pin/password, I notice it didn't work with the keyboard. Then when typing it on laptop keyboard it worked. I then noticed several keys did not work. It is the spacebar, n and b keys and also some of the arrow keys. The up arrow key worked for some reason. I then pressed it many times and it didn't work. Then a bit later, it worked. Are these buttons stuck or something? Now my wired keyboard... is very old and dirty. There is literally dirt and trash inside the keys in the keyboard. The thing is I find this keyboard very comfortable so that is why I still use it. It is from an old dell xps 8100 desktop from over a decade ago and this keyboard is comfortable. Now at the moment, the keys do work. But if it doesn't work again, is this 100% the external keyboard if my laptop keys work without any issue? Is it possible because I entered my windows password wrong many times, this occurred? However, I think that isn't the case since when trying to enter my windows pin/password when computer is locked, those keys already didn't work? The pin/password does contain either the b or n letter etc. This is certainly not a driver issue then again and it has to be the external keyboard? Is there a way to clean it or remove all the dirt and trash from it? I did wipe it with alcohol and tissue but you can't get into the dirty inside. It is literally like trash and dirty inside the keyboard. - - - Updated - - - So as of now, those buttons sometimes doesn't work. I have lot of dirt, inside the keyboard but it has been like that for a long time though. So is this a stuck key or something else? Dell keyboard from old dell xps 8100 desktop from back then. Dell SK 8165 is the keyboard. There is everything you can imagine inside the keys. The thing is i don't want to risk damaging the keyboard as i cannot buy another english keyboard here. Also want keyboard like this. As of now, the letters b, n, diagonal, arrow keys do not work. So me posting a picture of my keyboard you can give me the best advice here? Thing is if i was in us now, i can buy another one but can't here so sort of don't want to risk damaging the other keys. Any point in this below? Or is this the specific keys? Run DISM and SFC if have not done so. Check in Device Manager as to what Driver is being used for it. If it is a windows Driver from 2006 then that is possible issue as if taking Drivers from Windows Update it has replaced it. A common cure for keyboard and mice issues is to delete the driver in Device Manager and to reboot. It will be recreated at start up

 

Spacebar, Letters N and B and Arrow Keys Sometimes Not Working?

The way that I am analyzing this is that since the "b" & "n" letters are right next to each other, implies the high possibility that something liquid spilled in to that part of the keyboard, and the same thing with your arrow keys, since they are all next to each other as well. That's the only conclusion that I am reaching by reading your post... Is it possible to buy a keyboard online to get it shipped to you. Does your location accept package drop-offs? or even better, I just noticed: 1) Go to ebay.com 2) Search for: computer keyboard 3) Press Local & Check that box

4a) Maybe somebody near you is selling a keyboard you can try out. You can maybe go to that person's location, ask them for the very kind possibility if you can "temporarily" buy the keyboard so you can check if it works with your computer, and you can try those letters and arrow keys on the keyboard, and if they work, then we know that your current keyboard is messed up, and if you like the "temporary" keyboard, you can maybe keep it. Just some ideas. Check it out. 4b) Also, if your location accepts package drop-offs, you can buy a keyboard with free returns, and try it out. You get the idea.

 

Windows Key + Spacebar not working

Kathleen

Tried using SFC as you suggested and it went through all the steps successfully, but Windows key + Spacebar still doesn't work.

Looked at the link you gave and I see that one of the posts with a similar problem was using an HP Pavilion - same as me.

But it was the keyboard shortcut was working till the upgrade.

I've not tried Andre's suggestion yet.
