To troubleshoot the issue of your Surface Pro being stuck on the lock screen, there are a few steps you can try:
1. Press the power button for 20 seconds: This is a common method to force a hard reset on Surface devices. By holding down the power button for a longer duration, you can ensure that the device completely powers off and any lingering issues are resolved. After 20 seconds, release the power button and try turning on the device again.
2. Boot to UEFI: If the issue persists after performing a hard reset, you can try booting the device into UEFI mode. To do this, turn off your Surface Pro completely. Then, press and hold the volume up button on the side of the device. While still holding the volume up button, press and release the power button. Continue holding the volume up button until the Surface logo appears on the screen. This should take you to the UEFI menu. Check if the issue occurs in this mode. If it doesn’t, it could indicate a software problem rather than a hardware issue.
3. Disconnect peripherals: Sometimes, external devices like keyboards or mice can cause conflicts or issues with the device’s boot process. Try disconnecting any peripherals that are connected to your Surface Pro, including USB devices, and then attempt to turn on the device again. If the issue was caused by a conflicting peripheral, this should resolve it.
If none of these steps solve the problem and your Surface Pro is still stuck on the lock screen, it may be necessary to contact Microsoft Support for further assistance. They can provide additional troubleshooting steps or guide you through the process of repairing or replacing your device if needed.
