Using the Optical Drive on Battery Power Since an optical drive consumes a lot of power, your overall battery life will be shorter when operating the drive continuously (such as watching a DVD movie) than during standard operation. Many movies run-times are longer than your LifeBook notebook can support on a single battery. If you are watching a DVD movie on battery power you may need to swap in an additional, charged battery or attach AC power during the movie to view it in its entirety. • PROLONGED USE OF THE OPTICAL DRIVE, SUCH AS WHEN WATCHING A DVD MOVIE, WILL SUBSTANTIALLY REDUCE YOUR NOTEBOOK'S BATTERY LIFE. • AN ADDITIONAL FULLY-CHARGED BATTERY IS HIGHLY RECOMMENDED IF YOU WILL BE WATCHING DVD MOVIES ON BATTERY POWER. IF YOU DON'T HAVE AN ADDITIONAL BATTERY, YOU MAY PURCHASE ONE EITHER ON-LINE AT US.FUJITSU.COM/COMPUTERS OR CALL 1-877-372-3473. To Watch a Movie on Battery Power: 1 Have an additional full-charged battery or your AC adapter ready for use. 2 Start watching your DVD movie. 3 If a low battery warning occurs, immediately stop the movie and exit the DVD/CD-RW application. IF YOU DO NOT STOP THE OPTICAL DRIVE QUICKLY AND THE LIFEBOOK NOTEBOOK ATTEMPTS TO AUTOSUSPEND (CRITICAL BATTERY LOW STATE) THE NOTEBOOK WILL SHUT DOWN IMPROPERLY. IF THIS OCCURS, YOU WILL NEED TO INSTALL A FRESH POWER SOURCE (EITHER A CHARGED BATTERY OR AC ADAPTER). 4 Connect an AC Adapter to your system, or install a fully charged battery in the Flexible Bay (after removing any modular devices that may be present in the bay) prior to removing the main battery. 5 Manually place your notebook into Sleep mode by depressing the Suspend button then replace the discharged battery with a fully-charged battery. 6 If you removed the optical drive from the Flexible Bay in step 4, reinstall it now. 7 Resume your notebook by pressing the Suspend button again. This step is not required if you attached AC power without entering Sleep mode. 77 - Optical Drive

Using the Optical Drive on Battery Power
Since an optical drive consumes a lot of power, your overall battery life will be shorter when operating
the drive continuously (such as watching a DVD movie) than during standard operation. Many movies
run-times are longer than your LifeBook notebook can support on a single battery. If you are watching a
DVD movie on battery power you may need to swap in an additional, charged battery or attach AC power
during the movie to view it in its entirety.
To Watch a Movie on Battery Power:
1
Have an additional full-charged battery or your AC adapter ready for use.
2
Start watching your DVD movie.
3
If a low battery warning occurs, immediately stop the movie and exit the DVD/CD-RW application
.
4
Connect an AC Adapter to your system, or install a fully charged battery in the Flexible Bay (after removing any
modular devices that may be present in the bay) prior to removing the main battery.
5
Manually place your notebook into Sleep mode by depressing the Suspend button then replace the discharged
battery with a fully-charged battery.
6
If you removed the optical drive from the Flexible Bay in step 4, reinstall it now.
7
Resume your notebook by pressing the Suspend button again. This step is not required if you attached AC
power without entering Sleep mode.
