Hello, Surfertm.
Welcome to Microsoft Community!
In fact the highlight of the Surface Laptop 7 is a 2-in-1 device that can support both touch control and keyboard and mouse control.
After disabling the touchscreen on the Microsoft Surface Laptop 15-inch touchscreen Copilot+ PC laptop, you can still use the keyboard and trackpad for most tasks, but it may affect some features and experiences. Here are the specific impacts:
1. Touchscreen functionality
With the touchscreen disabled, you will not be able to perform actions such as tapping, swiping, or zooming by touching the screen. These operations need to be done through the keyboard and trackpad.
2. Application compatibility
Some applications (such as drawing software or touch-optimized applications) may require a touch screen to function fully. Disabling the touch screen may degrade the experience of using these applications.
3. Multitasking
The touchscreen provides convenience in multitasking operations, such as quick application switching or gesture operations. When disabled, these operations need to be accomplished via keyboard shortcuts or touchpad.
4. Portability
The touchscreen provides additional convenience in mobile work, such as quick markup or presentations in meetings. When disabled, these scenarios may not be as convenient as before.
5. System Settings
You can disable the touchscreen in Settings > Device > Touchscreen. You can always return to this setting if you need to re-enable it.
To summarize
Disabling the touchscreen will not completely limit the use of your computer, but it may affect certain features and experiences. If you rely primarily on the keyboard and trackpad, the impact may be minor; if you use the touchscreen frequently, it is advisable to disable it with caution.
I hope this information has been helpful.
Best Regards.
