In cases where users suddenly can't use the mouse and keyboard on their laptop, it's not uncommon and has many potential causes. This can be a hindrance, affecting your work efficiency. If you have the time, try troubleshooting with the methods shared by Mytour below to address the issue on your own, gaining some knowledge instead of having to take your laptop to repair centers.
Fixing laptop issue: Mouse and keyboard not recognized
1. Restart your laptop
In the case of a laptop not recognizing the mouse and keyboard, the first thing you should do is restart your device. Although it may seem simple, sometimes it brings unexpected benefits, such as helping to stabilize the system and resolve conflicts between software. Therefore, regardless of the issue you're facing, the first thing you should do is restart the device.
2. Check the On/Off Touchpad Settings
Check if someone accidentally turned off the touchpad on your laptop. Some laptop models have a built-in button to toggle the touchpad or use a key combination like Fn + a key from F1 to F12 with a computer mouse icon to turn the touchpad on and off when needed.

3. Missing mouse driver for the computer
Your computer may not recognize the mouse because, after installing the operating system, you haven't installed the mouse driver or the Ghost version has been finely tuned, removing many components. As a result, the mouse device doesn't interact with the operating system, leading to your computer being unable to control the mouse. To check if the computer has installed the mouse driver, follow these steps:
Step 1: Press the Windows + R key combination to open the Run dialog, type devmgmt.msc , and then press Enter or OK.
Step 2: The Device Manager interface appears; double-click on Mice and other pointing devices to check if the computer has installed the necessary drivers. If not, you can visit the official website of the laptop's manufacturer to download the latest driver package.
Moreover, if you don't know how to download drivers for your device, you can use Driver Easy to scan and automatically download drivers.
4. Check the connection ports.
In cases where users use an external mouse connected to the laptop via a USB port, it's possible that the computer's connection port has corroded over time due to lack of use, or the mouse plug's contact points are deteriorated. In such situations, clean your computer, wipe it, or use a paper towel to clean and polish the rusty plug contacts before reconnecting to see the results.
5. Run a virus scan
Computer viruses are a common cause, as they can block connections or damage system files, rendering the computer unable to function normally. It's advisable to install at least one antivirus software, even if it's free, especially if you frequently use internet connections. Readers can refer to the list of best antivirus software for computers that Mytour has previously shared to choose a suitable program.
6. Hardware malfunction
If you've tried most of the methods above and your laptop still doesn't recognize the mouse and keyboard, there's a high possibility that your computer has hardware issues, such as a damaged mouse control chip, a broken connection wire between the mouse or keyboard and the mainboard, etc. To address this cause, you need to take your computer to reputable repair centers for the most effective solutions. Additionally, a faulty or depleted battery in the mouse is not uncommon. Try plugging the mouse into another computer; if it's not recognized, then your mouse is likely damaged or the mouse wire is broken.
