My Acer Nitro 5 keyboard stopped working after a system restore — how can I fix it?

Question

A few days ago, I experienced multiple blue screens on my Acer laptop, even after restarting and shutting it down. That's why I decided to perform a system restore to fix the issue. However, after the restore, my keyboard stopped working in Windows. Fortunately, it still works in the BIOS, but it does not function once Windows loads.

I have already tried several solutions, including:

Updating the keyboard driver

Uninstalling the keyboard driver and restarting the laptop

Installing the Chipset driver followed by the Serial IO driver from Acer Support

Disconnecting and reconnecting the laptop battery

Installing all Windows updates and running other troubleshooting steps

Has anyone experienced this issue before, and what other possible solutions could fix this problem?

Thank you in advance.

Answer 1

It sounds like you're experiencing a frustrating issue with your Acer Nitro 5 keyboard after a system restore. Since your keyboard works in the BIOS but not in Windows, it suggests that the problem may be related to software or drivers rather than hardware.

Here are a few additional troubleshooting steps you can try:

1. Disable Fast Startup: Sometimes, the Fast Startup feature can cause issues with hardware recognition. You can disable it by going to Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable, and then uncheck "Turn on fast startup".
2. Check for Third-Party Software Conflicts: Boot your laptop in Safe Mode to see if the keyboard works there. If it does, a third-party application may be interfering with the keyboard functionality in normal mode.
3. Use Device Manager: Open Device Manager, find your keyboard under "Keyboards", right-click it, and select "Uninstall device". Restart your laptop, and Windows should automatically reinstall the driver.
4. Run Windows Troubleshooter: Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters, and run the keyboard troubleshooter.
5. Restore Previous Drivers: If the issue started after a specific driver update, you can roll back the driver to a previous version in Device Manager by right-clicking the keyboard device, selecting "Properties", and then the "Driver" tab to find the rollback option.

If these steps do not resolve the issue, you may want to consider performing another system restore to a point before the keyboard issue began, if available.

1

Open Command Prompt, then paste in this command and press Enter:

msdt.exe -id KeyboardDiagnostic

Run that Keyboard Troubleshooter to see if that can find and resolve the problem.

If that does not resolve the problem.

Open the old Control Panel (not the settings app)

At the top of the old Control Panel, set view to icons

Open Power Options

On the left, click 'Choose what the power buttons do'

At the top right, click 'Change settings that are currently unavailable'

Under 'Shutdown settings' disable 'Turn on fast startup'

Save that and close Control Panel

Then, restart (not shut down) your laptop to apply the change and test if the keyboard is working.

Hi R Jay Billones,

Welcome to the Microsoft Q&A forum.

Since the keyboard is responsive in BIOS but stops working once Windows loads, this typically indicates a Windows configuration or driver-related issue rather than a physical keyboard problem.

In addition to the Q&A Assist's answer, here's the clarification of the checking steps that you can follow:

1 - Use On-Screen Keyboard and Reinstall Keyboard Devices

• On the sign-in screen, select Accessibility > On-Screen Keyboard to log in.
• Once logged in, open Device Manager, uninstall all devices under Keyboards, then restart the laptop.

2 - Disable Intel Integrated Sensor / Serial IO (if listed)

• In Device Manager > System devices, locate Intel Integrated Sensor Solution (or similar), disable it, and restart.

If the issue persists, an in‑place Windows repair can refresh core system components while keeping your data intact.
