On Windows 10 login, my "P" key does not function in the password field. I can get around the problem in two ways:

  • If I instead use my PIN to login, the P key works just fine once I'm actually logged-in and using applications.
  • Also, if I click the "forgot password" link, Windows tries to take me to the reset password screen, BUT that screen fails and I'm returned to the login screen. At that point the P key does work.

So bizarre. It's behaved like this for four days. It happens with both the USB keyboard that came with the computer and my bluetooth Microsoft-branded keyboard. Switching keyboards mid-entry does not fix the problem, and I haven't had a problem with any other keys. Any ideas on how I can fix this?

  • Is "P" on a Num or Shift lock? That is one likely explanation

  • @John, no; it is on neither.

    Shut down and try the other keyboard. Switching keyboards will not help. "P" works on my machines.

  • @John once again, turning it off and back on again to the rescue. No more trouble (for now, anyway), and didn't even need to switch keyboards. Garrgh. I hate that that solution is a thing.

    I'm experiencing what I think is the same issue. What I find interesting in my case is that not only is the physical 'P' key ignored, so is the 'P' key on the onscreen keyboard - but ALT+112 is accepted. community.spiceworks.com/topic/… suggests that it may be to do with the screen-select menu displayed by Windows+P.

Switching keyboards will not help because of the native connection of the keyboard within the machine. "P" works on my machines, so try the following: Shut down entirely, restart and check if "P" is working. Also try a different keyboard using the same process.


You can also use an Alt code. Try holding Alt and typing 80 on the keypad (Numlock on) then let go of the Alt, that should input a "P" or 112 for "p".


However, it sounds like it just needs a Windows "fix", aka reboot.

  • Nice. That solution works, too.

I had the same issue when I came in in the morning and tried to log in to my computer. I had a second keyboard, so I swapped it out and had the same issue. Rebooting the computer fixed the problem.

Note: Both keyboards are Logitech wireless keyboards.

I also experienced that this morning. My laptop is an HP Envy.

The letter 'p' jumped to another line. It was weird. I wrote all the numbers and the alphabet, and when I pressed 'p', it goes to the right side, and next letter 'o' would be at its left. I also wrote the numeric characters, but they showed different characters. Stopped for a while as I got stressed.

Closed the laptop and let it 'breathe' for a while. Then when I opened it, I reviewed some apps installed, uninstalled unnecessary ones.

Finally, I cleaned my keyboard with cotton and disinfectant. I read somewhere online to touch some special keys like 'shift', 'ctrl', etc a few times. I decided to just clean it gently. It worked.


This looks like a very weird software bug that keeps happening to me from time to time. Only solution is reboot or use the alt code.
