Hi Kushveen,
Welcome to Microsoft Community.
I'm sorry to hear that you're experiencing issues with your Surface Book 2's touch screen. Based on the symptoms you've described, it's possible that there may be a hardware issue with the device. Unified Extensible Firmware Interface (UEFI) is a type of software that helps Windows communicate with your Surface’s hardware. Because UEFI operates independently of Windows, testing hardware in UEFI will work if you have a hardware issue.
- If touch does not work in UEFI, your device likely has experienced a hardware failure and needs servicing.
- If touch works in UEFI, the issue probably involves Windows or the touch driver.
Follow these steps to boot to UEFI and test touch functionality:
- Go to Start > Power > Shut down .
- When Surface is off, press and hold the volume up button and press the power button until a Microsoft or Surface logo appears onscreen.
- Once you are in UEFI, touch your Surface screen and see if it responds normally. Try to navigate in UEFI by tapping various menu items. Then, depending on how your Surface responds to touch, follow one of these steps:
- If touch doesn't work on your Surface, your touchscreen most likely experienced a hardware failure.
- If touch works on your Surface, select EXIT, follow any onscreen instructions, and restart Windows. Reset Surface.
If you’re still having a problem with your touchscreen, try resetting your Surface. To learn how, see Restore or reset Surface for Windows and follow the recommended steps for "Reset this PC."
If you have performed the above troubleshooting and the touchscreen still does not work, you may have a hardware failure. Unfortunately, because this model has been discontinued, out of warranty support and service for such models is no longer available. We appreciate your commitment to Surface and apologize for any inconvenience. Your SincerelyHahn. W - MSFT | Microsoft Community Support Specialist
