Home / Driver Updater / Keyboard
The laptop keyboard stopped responding after a Windows update, a USB keyboard lights up but types nothing, or Device Manager shows “Standard PS/2 Keyboard” or “HID Keyboard Device” with a yellow triangle and code 10 or 19. On a laptop the keyboard sits on a controller with its own driver and often a filter driver from the maker, and that is where things break. The free scan shows which driver is missing or failed.
Your PC is currently running: Windows
The built-in keyboard stopped working after a Windows update or a restart, while an external USB keyboard works. Typical of a failed PS/2 or I2C keyboard driver or the maker's filter driver.
Device Manager shows the keyboard with a warning mark and says the device cannot start or its configuration information is incomplete. The driver is installed wrong or the entry is damaged.
The keyboard lights up, but Windows does not install it, or it works in BIOS and not in Windows. A typical sign of a missing or failed driver.
Fn keys, volume and brightness keys or the backlight do nothing, the rest types fine. These depend on the maker's hotkey driver installed alongside the keyboard.
A free scan can identify the installed hardware and show available driver information.
These are the standard Windows checks - they take a few minutes and sometimes do the trick:
The weak spot of the manual route: at the "Update driver" step Windows searches only its own catalog, which is often missing or outdated for the exact model - it can report that the best driver is already installed even when a newer one exists. The free scan checks your devices against a database of 1,000,000+ drivers, so one pass shows whether better versions are available.
The application identifies the hardware installed on your PC and checks the current driver information.
See detected devices, installed driver versions and available updates. Nothing changes during the scan.
Review the results and decide which available updates you want to apply.
A license is required only if you choose to apply the available updates.

Yes. For an external keyboard it checks the keyboard entry and the USB port it is plugged into, and shows which of them is missing a driver or running an outdated one. Nothing is installed until you choose.
Yes. It reads the hardware ID of the keyboard controller and the filter device it sits on, such as “Elan keyboard filter device” or the Synaptics, HP or Lenovo equivalents, and matches them against the driver database. These are exactly the entries that break after a Windows update and that a plain Windows install often fills with a generic driver.
No. Nothing changes during the scan. Driver updates are applied only after you review the results and choose what to update.
Yes. Each detected item can be reviewed, applied or skipped individually. Backup and restore options are available before updates are applied, so a previous driver version can be restored if necessary.
The button downloads Outbyte Driver Updater, a Windows desktop application. The website itself does not scan your computer in the browser - the check runs in the application after you install and start it.
The scan and results are free. A license is required only if you choose to download and apply the available updates. Current pricing and license terms are shown before purchase.
Supports Windows 11 and 10 · Uninstall anytime via Settings → Apps · If no updates are found, the scan still shows the current driver state of your devices.
