Possible solution
Unplug and reconnect the mouse cable to your computer.
If the mouse is still not detected, turn off the computer, unplug
and reconnect the mouse cable, and then restart the computer.
Restart your computer by using the keyboard:
1 Press the Alt and Tab keys on the keyboard simultaneously
to navigate to an open program.
2 Press the Ctrl and S keys on the keyboard
simultaneously to save your changes in the selected
program (Ctrl+S is the keyboard shortcut for Save on
most—not all—programs).
3 Repeat step 1 and step 2 to save changes in all open
programs.
4 After saving changes in all open programs, press the Ctrl
and Esc keys on the keyboard simultaneously to display
the Windows Start Menu.
5 Use the arrow keys to select the Arrow button next to
Shut Down, select Shut Down, and then press the Enter
key on the keyboard.
6 After the shutdown is complete, unplug and reconnect the
mouse connector to the back of your computer, and then
turn on your computer.
For an optical mouse:
Clean the optical mouse: Gently wipe the light sensor lens
on the bottom of the mouse with a lint-free cloth (not
paper).
Use a mouse pad, white sheet of paper, or other less
reflective surface under the mouse.
