Installing a Secondary Battery Pack in the UltraBay
Installing a Secondary Battery Pack in the UltraBay
You can extend battery operation time by using two battery packs
installed in the computer at the same time. A secondary battery
pack is available as an option. Before installing a secondary battery
pack,  remove the CD-ROM drive or diskette drive from the UltraBay.
Attention:
To prevent damage to the CD-ROM
drive or diskette drive,  make sure the
AC Adapter is disconnected from the
computer.
The CD-ROM drive and diskette
drive are very delicate devices that
need careful handling. Do not press
on,  drop,  or apply any shock to the
CD-ROM drive or diskette drive while
it is removed from the computer.
1
Stop any running applications; then make sure the CD-ROM
tray is closed or any diskette is removed from the diskette
drive.
2
Turn off the computer; then disconnect the AC Adapter and all
cables from the computer.
Attention:
Make sure the security latch at the
right side of the computer is
unlocked. (See  step 2 on page 7.)
3
Open the LCD; then open the keyboard.
4
Lift the drive handle with the plastic tape,  and remove the
CD-ROM drive or diskette drive.
