Windows 10: Some keys randomly stop working on laptop keyboard

Hello thereWhy do some of my keys randomly stop working and work again after I press the shift button?My keys D, Backspace, and + stop working randomly and sometimes work again after I hold shift and press them again.It looks like a software issue because when I wake up one key other mentioned work too for some time. I tried everything reinstating drivers lifting keys and cleaning dust, but nothing worked.I'm using an ASUS Rog M16 2023 with built-in Windows 11.

Laptop keyboard randomly stops working.

My laptop keyboard randomly stops working. The only way to get it back to work is by a hard reset (press the power button to shut off the laptop or navigate in the system and press shut down). The it will work for an undetermined amount of time (it could be few minutes, hours, days or even week) and then randomly stop working again. Sometimes it happens multiple times a day. I have the BIOS updated to the latest version. Any suggestions how I can fix this problem as it is extremely frustrating.

My laptop is Dell XPS 9380. I contacted Dell and they want to replace the keyboard. It is clearly not a hardware issue. Please advise if there is a way to fix this problem.

 

Built-in keyboard in laptop randomly stops working / no response

Try again with the pictures... I also included other pictures of the damage the heat has done to the plastic chassis of the laptop. Over the years the heat has become so extreme that bits of plastic around the exhaust grill has melted or chipped off. Also, you can see how the underside of the keyboard takes the brunt of the heat from the CPU fan and battery which sits just underneath the keyboard wires (in fact just a bit of tape separates the keyboard flat cable and the swollen battery.













Well, just now I tried another tactic. I remember I bought some memory from eBay to push my the capacity form 8gb to 16gb last year and they have worked flawlessly. But I just now put the original 8gb back in to see if its the memory that's causing the weirdness. Although as I've said in my experience failing memory usually gives BSOD, random lockups and hang etc. I'd be surprised how a memory could affect a laptop keyboard in this way but it could be the reason why I was getting problems at boot...

The problem usually shows itself when the laptop has to restart from a cold boot so I'm going to now do a series of a cold boot to see if the issues comes back. If not then ill put the newer 16gb memory back in and do a memory test over the weekend.


I'm starting to think the bios or the regulator that gives power to the keyboard is faulty on the mainboard. Those two issues are expensive fixes though.

 

Built-in keyboard in laptop randomly stops working / no response

Ok, so recently I found my Toshiba Satellite laptop keyboard sometimes stops working. Nothing at all. The number lock light stays on if it is on but no response from any of the keys....This happens sometimes at boot but sometimes it happens randomly after a successful boot. It can work for any amount of time and then stop working. On average though it usually happens within two hours though but can go all day before it happens again

I decided to take the nuclear option and reformat because I thought it was a virus.

So, after a reformat everything was good and then it started happening again. I haven't installed any software since reinstallation of windows.

I have another USB wireless keyboard and when to use that it works properly but the built-in one still doesn't work until I do a reboot and sometimes even after a reboot it doesn't work.


So what could this be:

1. My computer is 5 years old. Could it be that a dying CMOS battery could affect the keyboard and make it randomly stop working?

2. I also surmised that maybe there was a windows update that affected the keyboard but I haven't seen anything that relates to keyboard or other motherboard drivers being installed.

3. Or could it be the keyboard hardware itself, is it failing somehow? But why would it work properly sometimes after a reboot?

4. Or something else? that's why I came here to ask for suggestions or direct solutions



I appreciate any guidance on helping to solve this frustrating issue

PS:

I tried to use Event Viewer to see if there is an entry that would show if Windows has reported/noticed the keyboard malfunctioning but I don't know where to look in Event Viewer, it's above my technical ability to know exactly where to look. I have tried but I don't see anything obvious.
