Windows 10: a key on my keyboard stopped/not working after boot/startup Windows

Hi,
A key on my keyboard is not working after boot/startup Windows 10.
("V" key not working)
I had tried connecting two different keyboards (one MS keyboard, another from some mechanical gaming keyboard). Surprisingly the two keyboards behaVed exactly the same (only V key not working after boot-up).

Therefore I had figured out this issue is not keyboard/hardware related.

Another strange thing is, I could type "V" with pressing down 'shift' keys (either side. which means uppercase V are typable but not lowercase.. this is why you guys only see uppercase Vs in this post... sad)

I had also tried remoVing and re-installing the keyboard driVers but no luck (as soon as my computer fully loads Windows, "V" key stops working.)

Lastly, this key is not eVen working on the on-screen (or Virtual) keyboard of Windows 10. I was mad-clicking down the V key panel with my mouse, but no response.

I am so lost at this point and desperate now. Please help me....

:)

 

keyboard and mouse not working in safe mode

Hi, my laptop is Asus A550L, my brother just update the windows to windows 10 creator, and after that the keyboard and mouse stop working, only working in bios mode, after reading some internet tips i manage to also boot into Advanced Startup Options. than
after that i tried to boot to safe mode in case i can delete or reinstall the drivers, which fails.

This is when the problem got worse, windows refuse to boot to safe mode, which then, i use command prompt to force it to boot safe mode. after reaching the safe mode, my mouse and keyboard stop working again, and i cant open the bios or the Advanced Startup
Options (which can be accessed by f2/f8) again. Mistakes were made

So my question is, how to at least make the windows bootable back to bios or Advanced Startup Options and also to fix the not working keyboard and mouse after the first problem is solved

note that:

- I CANNOT USE my keyboard and mouse external nor internal

- This is a laptop that doesnt have ps2 port

- I`ve tried many mouse and keyboard and it doesnt work

p/s: sorry for my bad english

 

The "a" key has stopped working on my keyboard

Hi,

Keyboard issues might have been caused by an incompatible driver. For us to isolate the issue, we would like to know the following:

• Have you tried using other external keyboard?
• When was the last time that you are able to use your keyboard key properly?
• Have you made any recent changes to your PC settings prior to this issue?

In the meantime, we suggest that you follow the steps given on this article:
Mouse, touchpad, and keyboard problems in Windows.

We will wait for your response.

 

Assuming your keyboard works in Safe Mode, boot to safe mode and try there. If the problem disappears, it's a conflicting program.

If it won't work in Safe Mode, try a clean boot, and try again.
