ok - so I am typing this out using the on screen keyboard app in Windows 10. I am hoping that someone might be able to shed some light onto why i have suddenly lost the use of several keys on my laptop's keyboard.

 

The KEYS in question are a,d,x,b,n, full-stop,comma and question-mark.

 

The Computer is  a Samsung notebook np3530ec which is about 2 and a half years old. changed to windows 10 about a month ago.

 

I have used this device pretty much daily ever since, often typing 500plus word letters and magazine articles. However, seeing that all the keys concerned failed at once leads me to feel that general wear/tear is not the issue here?

 

However, I did clean the keyboard on the day the keys failed, but this was approximately 2 hours before the actual failure occurred - using a light mist of pc anti -bac spray and a silk cloth, taking care as i usually do to avoid any liquid penetration under the keys themselves.

 

I have since performed full/deep scans with  both avast and zemana which came back clean.

 

Fortunately, my pc password does not contain any of the failed keys, so for now at least, I can use the app's on-screen keyboard to reply to any members here who might wish to reply.

 

If necessary, i would be perfectly happy to perform  a complete  disk-reformat and start again back to factory settings if that's what it takes to resolve this issue as i have everything backed up. However, i obviously only want to do this as a last resort if all else fails.

 

I have also tried resetting/recovery back to a date prior to the failure of the keys, but for some reason, the process failed on the 2 occasions i tried .

 

I would be very grateful to anyone who can help me here as i cannot afford the cost of a new pc or any hefty repair bills, but would be quite happy to make a small (but not insignificant) paypal donation to a member who can come up with a fix that means me saving on expensive repairs etc.

 

Thanks for reading and i will be happy to answer any further questions put to me about this issue if required, although my responses are likely to be slow due to having to use the mouse - click onscreen keyboard app.

The possibilities are that either the keyboard has failed physically......or a driver is doing really strange things....if you connect another keyboard via a usb port, does it work ok, or is the same drama present there as well ?

Thanks for replying, Condobloke....

at present, i dont have another keyboard  to be able to try your suggestion, although it is feasible i might be able to acquire one in the next couple of days.

One thing i forgot to mention was that i lost power suddenly to my laptop an hour or so before the fault occurred due to a power-outage. I operate this laptop without a battery in order to keep it running as cool as possible, which in hindsight might not be such a good practise, i guess!

ok...you can reset the pc in windows 10.....by going to the start button>>>settings>>>update and security>>>>>recovery>>>>>Reset this PC........This lets you choose to Keep your files or remove them.....and then re installs Windows 10

followed your instructions, CB, But sadly the procedure didn't work in this instance.

I'm guessing that the problem might well be a little more serious than I had previously hoped, maybe to do with the cleaning of the keyboard or some irreversible damage to the drive caused by the power-outage.

I will try to obtain a usb keyboard in the next day or so to see if I can further isolate the problem.

thanks for showing interest in my problem.

hope to converse with you again soon

Update...thanks for your help, CB...It seems that I might have caused irreversible damage to my laptop keyboard due to over-exuberant cleaning - I got hold of an auxiliary keyboard and everything is working fine with it. I would obviously like to fix the keyboard on my laptop, but opening it up, inspecting and cleaning, I feel, is a little beyond the scope of my capabilities - so lesson learned I guess.

never mind - stuff happens!  :mellow:
