Answer 1

Hi JOSEPH DANIEL,

I understand your keyboard stops working in Windows (but works in UEFI), and the charging indicator is also missing. This usually points to a Windows/driver or system service issue rather than hardware.

Have you already tried the Q&A Assist suggestions? In addition, please confirm:

1. Is this a laptop built‑in keyboard or external USB keyboard?
2. When the issue happens, does Device Manager show any warning icons?

In the meantime, if:

• You’re on a laptop or built‑in keyboard (because of the charging indicator mention)
• The issue affects both input and battery status, likely related to ACPI / system drivers

Please try these steps:

1, Restart and reset Windows input-related services

1. Press “Ctrl + Shift + Esc” > open Task Manager
2. Click “File > Run new task”
3. Type: services.msc
4. Find and restart:
   • “Human Interface Device Service”
   • “Device Install Service”

2, Reinstall ACPI & battery-related drivers

1. Press “Windows + X” > “Device Manager”
2. Expand “Batteries”
3. Right‑click:
   • “Microsoft AC Adapter” > Uninstall
   • “Microsoft ACPI-Compliant Control Method Battery” > Uninstall
4. Restart your PC > Windows will reinstall them automatically

This can fix both charging indicator + keyboard response, since they rely on ACPI.

3, Check system files

1. Right‑click Start > “Windows Terminal (Admin)”
2. Run: sfc /scannow
3. Then run: DISM /Online /Cleanup-Image /RestoreHealth

4, Install chipset / system drivers from your manufacturer

Even after reinstalling Windows, some drivers are missing:

• Go to your laptop manufacturer’s website
• Download and install:
  • Chipset driver
  • Keyboard / ATK / Hotkey driver (if available)
  • Power Management driver

Because the keyboard works in UEFI, the hardware is likely OK and Windows (drivers, settings, or updates) is causing the issue. Try these steps in order:

1. Check basic hardware and USB

• If it is a USB keyboard, unplug it, wait 10–15 seconds, then plug it back in.
• Try a different USB port (preferably directly on the PC, not through a hub).
• If using a USB hub, remove the hub and connect the keyboard directly.

2. Test the keyboard on another PC

• Connect the same keyboard to another computer.
• If it does not work there either (outside of UEFI), the device may still have a hardware/firmware issue and may need replacement.

3. Update or reinstall keyboard drivers

• Press Windows key + X and select Device Manager (if the keyboard does not work, use a mouse or touchscreen).
• Expand Keyboards.
• Right‑click the keyboard device and select Update driver → Search automatically for drivers.
• If that does not help, right‑click the keyboard device and select Uninstall device, then restart Windows so it reinstalls the driver.
• Alternatively, use Settings → Update & Security → Windows Update → Check for updates to install any available driver or system updates.

4. Check for Windows 10 USB/keyboard update issues

• Some Windows 10 updates can cause USB keyboards or built‑in keyboards to stop working.
• If this started right after an update, boot into Windows, then go to Settings → Update & Security → Windows Update → Check for updates and install any newer cumulative updates that may fix the problem.
• If no input works in normal Windows but works in the Windows Recovery Environment, follow the documented recovery steps to restore USB functionality by installing the corrective update.

5. Turn off Fast Startup (if the keyboard only fails on cold boot)

• If the keyboard fails only on first power‑up but works after a restart, disable Fast Startup:
  • Open Control Panel → Hardware and Sound → Power Options → Choose what the power buttons do.
  • Click Change settings that are currently unavailable.
  • Clear the Turn on fast startup (recommended) checkbox.
  • Save changes and shut down, then power on and test.

6. Check for wireless/USB receiver issues (if it is a wireless keyboard)

• Replace the batteries with fresh, non‑rechargeable ones.
• Move the USB receiver to another USB port (preferably on the back of a desktop PC).
• Remove any USB hubs, KVM switches, or port replicators and plug the receiver directly into the PC.
• If the device has a Reset button (on the keyboard or receiver), press it to resync.

If after these steps the keyboard still works in UEFI but never in Windows (and another keyboard works fine in Windows on the same PC), the failing keyboard is likely defective at the protocol/firmware level and should be replaced.
