Have you checked for a dedicated ‘Log’ button or switch on your keyboard or laptop?
This one caught me out for a while. Some keyboards, especially on laptops, hide a tiny button or switch labelled “Log” or “Log On” somewhere around the edges or near the function keys. On many laptops, it’s a small physical switch or a toggle integrated into a function key — flipping it off and on can completely disable or enable the keyboard input. If you’re stuck at the Windows login screen and your keystrokes aren’t registering, it’s worth checking if such a switch exists. Usually, it’s located on the side, top corner, or combined with another key that requires you to hold the Fn key. Often, this is a Function key toggle or a physical switch. Turning it off should let your keystrokes show up in the password box again. It sounds obvious now, but I missed this at first — and it’s a common reason why your keyboard might seem dead even if it’s perfectly fine otherwise.
Try unplugging and swapping your keyboard
If you’re on a desktop with a wired keyboard, simply reconnecting it can sometimes do the trick. USB ports can be temperamental—especially if you’re using a front port or a hub. I’ve had moments where unplugging the USB cable, waiting a second, then plugging it into a different port (preferably one directly on the motherboard rather than a hub) fixed the issue. It’s a quick check — if your keyboard still doesn’t respond after that, try another keyboard entirely. This isn’t just about hardware testing; it helps determine whether the problem lies with the keyboard itself or something deeper like the USB port or driver. On my older ASUS, sometimes a port was dead or the connection was loose. If you’re using a laptop, try plugging in a different USB keyboard to see if that one works better. If it does, then your original device may have a hardware fault or port issue. It’s worth spending a few minutes checking this before diving into more complex fixes.
Check that your wireless keyboard is connected and charged
Wireless keyboards can be the sneakiest culprits. They rely on Bluetooth or a dedicated RF receiver plugged into your USB port. First, make sure it’s charged — there’s nothing worse than realising the batteries died at the worst moment. Then, double-check that it’s properly paired or connected. You can do this via Windows’ Bluetooth settings: Settings > Devices > Bluetooth & other devices. Sometimes Bluetooth gets turned off after updates or restarts, leaving the keyboard just sitting there, not connected. Also, head to Device Manager and look under Bluetooth. Confirm that your Bluetooth adapter is enabled and working properly — no warning icons or disabled statuses. Re-pairing the device often fixes the problem, especially if everything else seems fine but you still can’t type. It’s frustrating when the device shows as connected but doesn’t send keystrokes, but re-establishing the link usually resolves the issue.
Rebooting often sorts out weird glitches
I know, everyone says “restart,” but it really does help. Sometimes Windows glitches and doesn’t recognise the keyboard properly, especially on login screens, USB issues, or after updates. The trick that finally worked for me was doing a forced shutdown: hold down your Power button until your system powers off, then, if possible, unplug the power cord or remove the battery (if your laptop has a removable one). Wait a minute or two — just enough to drain residual power — then plug everything back in and turn it on. I’ve seen this reset hardware caches and make the keyboard reappear. Often, that’s all you need to get your typing working at login. It’s an easy fix before you start fiddling with drivers or BIOS settings.
Use the on-screen keyboard at the login screen
If your physical keyboard refuses to cooperate, try the Windows On-Screen Keyboard. On the login page, look for the “Ease of Access” icon — usually a little icon at the bottom right corner of the screen. Click it and select “On-Screen Keyboard”. Alternatively, press Windows + Ctrl + O within Windows to activate it. Once the virtual keyboard appears, use your mouse to click in the password box and type as normal. This can be a lifesaver when there’s a software glitch or driver problem hindering your physical keyboard from working at startup. It allows you to get into Windows and start troubleshooting from there, rather than being completely locked out.
Check if any background apps are interfering with keyboard input
Sometimes, the issue isn’t hardware or connections — it’s certain apps or utilities that launch at startup and hijack input drivers. To investigate, press Ctrl + Shift + Esc to open Task Manager. Go to the “Startup” tab. Here, you’ll find a list of programs that run when Windows starts. Look for any unfamiliar or suspicious entries, like security tools, language utilities, or UI overlays, that could be conflicting with your keyboard drivers. Disable any that seem dodgy by selecting and clicking “Disable”. Then, reboot and see if your keyboard works at the login screen. Sometimes, a background app or driver conflict can hijack your input during startup, and disabling these programs can fix it. You can also check Event Viewer (type eventvwr.msc in the Run box) for warnings or errors related to input devices to get more clues.
Ultimately, if you can’t type your password at login, it’s usually a hardware toggle, connection issue, driver glitch, or a conflicting app causing the problem. Going through these common checks — inspecting switches, reconnecting or trying alternate keyboards, using the virtual keyboard, and reviewing startup programs — can often get your keyboard working again. Don’t get discouraged — I’ve been there myself, and once you identify the culprit, it’s often simpler than it first appears.
Hope this helps — it took me ages to figure out myself. Hopefully, this guides someone else through a quicker fix and saves them a weekend.
