2. Electrical tape to tape the old battery after removal
3. QWERTY keyboard to restore CMOS memory settings after replacing the

ESD WARNING!
Protective measures against electrostatic discharge (ESD) must be taken when
working inside of any computer. Failure to do so may result in permanent
damage to electrical components within. This damage may be immediate or
latent (final computer failure may occur at a later date). Be sure to make
consistent ‘skin to metal’ contact with the computer chassis when making
contact with any electrical assemblies or components.
TO GAIN ACCESS TO THE BATTERY AND REPLACE:
1. Remove power from the 4600 series computer. If installed in a panel the
computer must be removed and placed screen down on a bench. To work
on the computer on the bench you must first place a soft clean cloth on the
clean surface of the bench in order to prevent scratches to the display
overlay or touch screen. If the computer includes a front panel mouse,
then be sure to prop up the bottom edge of the front panel with a soft
object in order to prevent damage to the panel mouse controller. Do not
rest the face of the computer on the mouse controller.
2. Remove the top cover of the rear chassis (4612: four #6 screws, 4615: five
#6 screws)
3. Locate the battery holder and remove the coin cell battery:
