Appendix 89

Optimizing Power Consumption and Battery Charge Time

The AC adapter charges a completely discharged battery in approximately 3hours with the
computer turned off. Charge time is significantly longer if the computer is on and running at high
processor speeds and system activity levels. If you run your computer at high system activity levels
for extended periods of time and your battery is not charging, try running your system in Low
Power Mode. Low Power Mode can improve battery charge time and battery life. Depending on
system activity levels, system performance may be reduced. To set Low Power Mode:
NOTE: You can also click the power meter icon on the taskbar.

Variable Speed Fan

The computer uses a variable speed fan to prevent the computer from overheating. The fan runs
constantly, and fan speed may vary depending on usage. Fan noise is normal and does not indicate
a problem with the fan or the computer.
