5-10 minutes
Before You Begin
Two replacement kits are available:
z Wireless keyboard
z Wireless mouse with wireless receiver
IMPORTANT: The keyboard and mouse must be next to
the HP PC, within 1 foot (30 cm) and away from
interference with other devices.
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.
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.

6 Reconnect any cables that were disconnected for this
procedure.
Troubleshooting
If the computer displays a memory error after you have
turned it back on, check the following:
z Turn the computer off and unplug the power cord, then
open up the memory compartment and make sure the
memory card is firmly seated. To install it correctly,
make sure it inserted all the way into the compartment
and then push down on it to snap it into place.
z Verify that the memory installed is compatible with this
computer. SO-DIMMs are small outline dual inline
memory modules. They are smaller and thinner than
most other DIMMs, so that they take less space in the
case.
7 Plug the power cord into the back of the computer and
then into the power source.
8 Return the computer to the upright position and turn on
the computer.
SO-DIMM modules must meet the following
requirements:
z 200-pin DDR2-DIMM
z PC2-4200 (533 MHz) DDR2-SDRAM or PC2-
5300 (667 MHz) DDR2-SDRAM
z Unbuffered, non-ECC (64-bit) DIMMs
z 1.8 V memory only
z 4.0 GB maximum installable memory. Actual
available memory that can be used in Windows
will be less.
z Because the memory uses dual channels, you
should use the same DIMM type for both sockets.
