N B Space arrow keys stop working sometimes

Time after time lower part of the keyboard starts missing key presses. Especially keys N B space down arrow.
Previous discussions in this community ended up with conclusions that reinstalling drivers and/or replacing keyboard helps.

However, I believe that this is not the real solutions and here is why:

1. While searching for similar issues I noticed that people in many laptop owner forums (asus, lenovo, hp) have complained about exactly these keys malfunction. And the problem occurs for more than 3 years. I do not think that keyboards are the same on these laptops and for these years.

2. Sometimes missing keypresses come afterward resembling a buffer lag. I.e. You already release the key, but missing symbols come after a second. So this does not seem to be a purely mechanical issue. And the fact that my keyboard works well while writing this message supports this.

3. This may be somehow connected to Skype working on the computer. Right now I have closed Skype and my keyboard works perfectly. But when I start it again keys are not working well.

These observations allow me to conclude that:

1. Even though when specific keys are not working well, this is usually coffee in your keyboard and it requires replacement, a probability that many users of different laptops during years pour their coffee on the same set of keys equals zero.

2. BIOS and drivers issue is more probable, at least playing with drivers reinstallation and registry configuration seem to work, but as the effect does not last long, this is not a solution.

3. In my case, Skype affects keys issue and it has hotkeys that work when your skype app is in the tray. Maybe it starts working as an additional keyboard filter. What does not support this statement is that Skype introduced hotkeys in 2019, but the keys issue was reported long before.

Anyway this seems to be a rare and annoying problem. If someone has the same issue, I would like to ask you to check is there a connection to skype in your case and share if you had this problem solved by other means.

Maybe we still have a chance to avoid unnecessary warranty replacement and loss of time.

Re: N B Space arrow keys stop working sometimes

I have already answered in other thread, but as I'm the author of this one I will copy my text below:

I tried virtually all software options I could find on the net. Drivers, registry buffer sizes, removing unnecessary windows part, upgrading/downgrading BIOS.

I thought initially that it is a software issue because keys are working well, but not all the time. I thought so until I got Ubuntu flash stick and saw n b space etc not working there. So now I think this is a hardware issue.

Maybe Dell should consider if not a recall company, but at least doing something, like accepting problem exists and issuing guidelines describing the situation and showing us the fastest way possible to fix the issue. Like saying that serial numbers from A to B had a hardware issue which causes keys not working etc and requires replacement action or smth.

Reading forums for solutions and try and fail approach is OK for no-name copycat products named DEELL. I hope we are not there yet with our brand new laptops.

It looks like this forum part is a great place for feedback from the manufacturer.

I bought (for peanuts, fortunately) from China a replacement keyboard. Just to be sure that it is a hardware issue.

When you uncover your laptop, you see that keyboard inside a laptop is attached with molten plastic to the body. So you can't just unscrew and replace. You have to disassemble the whole thing, take your soldering iron, and probably your kid's toy as a source of plastic. Are screws so expensive that Dell decided to solder keyboards to the body? It's a replacement part for coffee maniacs like me.

The good news that clarifies the situation is that when I connect a new keyboard, my lovely n b space etc keys work! When I connect back they don't work again. Unfortunately, particularly this replacement keyboard had another set of keys broken. Can't blame Dell for this of course, but maybe it is because this keyboard is flexible as a sheet of paper? Cost-saving is something that must have a limit.

I'm completely disappointed with Dell quality and engineering approach for this product.

Re: N B Space arrow keys stop working sometimes

News on my situation. As I wrote before, I had an issue with n b space etc keys.

What I did, I ordered a replacement keyboard from China and I've got another set of keys not working on the replacement keyboard. I did not give up and ordered yet another one.

The second replacement keyboard works more or less fine. It costs $20.

What is interesting both defective keyboards, one installed by Dell factory, and another one from Aliexpress had the same manufacturer (according to a sticker on its back): Chicony Elec Co., Ltd. The third one, working, had another no-name brand, to my luck.

Replacing the keyboard is not very complicated (you will need small screwdrivers, a hot glue stick and some patience), but the laptop is designed in the way that replacing the keyboard is not expected because you damage & glue the case (fixation pins) by doing so, so the right way is to replace the "palm rest and keyboard assembly", which is basically the case of the laptop. And by doing so you will probably get another Chicony product as a part of the assembly...

Anyway, it works and I can replace keyboards as many times as I like for a price of a lunch.

Re: N B Space arrow keys stop working sometimes

@kazau, From my experience I can only suggest you buy an external keyboard if you need this laptop every day like me or deliver it to a service center for a keyboard replacement.
