Microsoft Surface Laptop model 2037
Because the cursor freezes only when Surface Connect power is attached, with two adapters, while USB-C charging works, the distinction is the charging path rather than the mouse itself. That pattern suggests a Surface Connect, firmware, power, or grounding problem, but it does not identify which one. Install Windows and Surface firmware updates, then run the Surface app’s help checks and the Surface Diagnostic Toolkit. Test the touchpad and an external mouse, first in Windows and then in Surface UEFI with the charger connected. If the failure also occurs in UEFI, Windows drivers and startup software are not the cause. If it occurs only in Windows, perform a clean boot and retest. Continue using USB-C if it is stable. Do not open or modify the charger. Record the charger wattage, serial numbers, and test results, then ask Microsoft Surface support to inspect the Surface Connect port and power hardware.
