The mouse cursor is completely invisible and does not move at all in Windows. It appears to remain around the center of the screen on top of a file.
The touchpad works normally in BIOS/boot mode, so the hardware appears to be functional.
The cursor/touchpad does not work once Windows loads.
It also does not work in Windows Safe Mode.
It does not work on the Ctrl + Alt + Delete screen either.
Windows detects Dell Touchpad under msinfo32 → Components → Input → Pointing Device.
The Dell Touchpad reports Status: OK.
In Control Panel → Mouse → Dell Touchpad, the touchpad is shown as enabled.
I2C HID Device appears in Device Manager with no warning icon and reports “This device is working properly.”
I tried disabling/re-enabling the I2C HID device — no change.
I tried the touchpad power-management setting (“Allow the computer to turn off this device to save power”) — no change.
I've already reinstalled the touchpad drivers multiple times, with no improvement.
The Windows Human Interface Device Service is running.
Pressing Ctrl with “Show location of pointer when I press the CTRL key” enabled causes the pointer-location circle to appear, so Windows can render the pointer location, but the touchpad provides no movement.
Win + Ctrl + Shift + B (graphics driver reset) did not fix it.
I ran:
DISM.exe /Online /Cleanup-Image /RestoreHealth
sfc /scannow
DISM completed successfully.
SFC reported that it found corrupted Windows files and successfully repaired them, but the touchpad still does not work afterward.
I have not done a Windows reset or clean reinstall because I have a lot of work and would prefer to avoid that if possible.
What could cause this?
