What You'll Learn
The issue could be caused by Windows
The issue of your laptop fingerprint reader not working after sleep mode could be caused by Windows. This is a common problem, affecting laptops from various manufacturers, including Dell and HP. It appears that Windows is unable to recognise the fingerprint scanner after the system wakes up from sleep mode. This issue seems to be caused by Windows 10's power management settings, which put the fingerprint scanner to sleep even when the system is awake.
To fix this, you can change the power management settings for the fingerprint reader. Here are the steps you can take:
- Open the Start menu by pressing the Windows key on your keyboard.
- Search for "Device Manager" in the Start menu and open it.
- Expand the "Biometric Devices" option.
- Right-click on the fingerprint device and select "Properties".
- Go to the "Power Management" tab in the properties window.
- Uncheck the "Allow the computer to turn off this device to save power" option.
Additionally, you can try updating the driver for your fingerprint reader. Outdated drivers can cause issues with hardware functionality. To update the driver, you can go to your laptop manufacturer's website and download the latest version. Alternatively, you can use a dedicated tool that will scan your system and update the drivers automatically.
Another workaround suggested by some users is to lock your laptop by pressing Windows Key + L before closing the lid to put it to sleep. This shortcut can be used on the lock screen to fix the problem temporarily. However, it needs to be done every time the computer goes to sleep, which may not be practical for some users.
If the issue persists, you can try uninstalling and reinstalling the driver for the fingerprint reader. Make sure to download the latest version of the driver from your laptop manufacturer's website.

A simple workaround is to lock your laptop before closing the lid
If your laptop's fingerprint reader is not working after waking it up from sleep mode, a simple workaround is to lock your laptop before closing the lid. This can be done by manually locking your laptop before closing it, or by using third-party tools to automatically lock it when you shut the lid.
Manually locking your laptop before closing the lid ensures that your laptop remains secure even when the fingerprint reader malfunctions. This adds an extra layer of security, as you will need to enter your password or PIN to unlock it. While this may not be as convenient as using your fingerprint, it is a straightforward solution that does not require any additional software.
Additionally, there are third-party tools available that can be used to automatically lock your laptop when you close the lid. These tools can be customised to suit your preferences, such as setting a delay before the laptop locks or requiring a logon anytime the lid is closed and reopened. This provides a more seamless experience, as you won't have to remember to lock your laptop manually. However, it's important to note that using third-party tools may come with risks, such as potential security or compatibility issues.
By employing either of these methods, you can ensure that your laptop remains secure even when the fingerprint reader is not functioning properly after sleep mode. This workaround provides a temporary solution until a more permanent fix can be implemented, such as updating your Windows or installing new fingerprint driver updates.
It is worth noting that this issue of fingerprint readers not working after sleep mode is not unique to a specific laptop brand or manufacturer. It appears to be a common problem across different laptop models, indicating that it may be related to the Windows operating system itself.
