3Removal and Replacement Procedures
The following sections provide information about disassembling various components of the HP Pro
All-in-One.
Preparing to disassemble the computer
To avoid injury and equipment damage, always complete the following steps in order, when opening
the HP Pro All-in-One.
1.Remove all media (CD, DVD, etc.) from the computer.
2.Shut down the computer.
3.After the system has completely shut down, disconnect the power adapter from the back of the
HP Pro All-in-One.
4.Disconnect all other attached cables from the back of the computer.
5.Place the computer face down on a soft flat surface. HP recommends that you set down a
blanket, towel, or other soft cloth to protect the touch screen surface from scratches or other
damage.
WARNING!Beware of sharp edges inside the chassis.
6Chapter 3 Removal and Replacement Procedures
Replacing the Keyboard or Mouse
1.Leave the computer on.
2.If you are replacing the wireless mouse, remove the old receiver and plug the new receiver into
the back of the computer. Skip this step if you are replacing the keyboard only.
3.Remove the tab from the battery compartment on the bottom of the mouse and/or the keyboard.
This activates the pre-installed battery.
Replacing the Keyboard or Mouse7
4.If you are replacing the mouse and it has a power switch on the bottom, turn on the mouse
power switch (A). The keyboard does not have a power switch, so you can skip this step if you
are installing the keyboard only.
5.Press the blue connect button on the bottom of the keyboard (B) and/or mouse (C) for 5 to 10
seconds. The blue activity LED on the wireless receiver illuminates when the synchronization
command has been received and goes off when synchronization is complete.
NOTE:If the synchronization does not work, remove and then re-insert the wireless receiver from
the back of the computer and synchronize the keyboard and/or mouse again.
