Refer to the documentation that came with the keyboard and mouse.
Unplug and reconnect the mouse cable to your computer.
If the mouse is still not detected, turn off the computer, 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 After saving changes in all open programs, press the Ctrl and Esc keys on
the keyboard simultaneously to display the Windows Start Menu.
4 Use the arrow keys to select the Arrow button next to
the Lock button. Select Shut Down, and then press
the Enter key on the keyboard.
5 After the shutdown is complete, reconnect the mouse connector to the back
of your computer, and then turn on your computer.
If you have a rollerball mouse, clean the roller ball. For detailed cleaning
instructions, go to: http://www.hp.com/support
Select your country/region and language, search on your computer model
number, and then search on the keyword cleaning.
For a mouse with a roller ball, use a mouse pad or other rough surface under
the mouse. For an optical mouse, try a less reflective surface under the mouse.
