BATTERY CAPACITY — Performance is reduced when the computer is running
on battery power and power consumption exceeds the battery’s rated capacity or
exceeds allowable safe discharge levels, or when the battery surface temperature
exceeds 60°C.
Optimizing Power Consumption and Battery Charge Time
The AC adapter charges a completely discharged battery in approximately
3 hours 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.
1 Click the Start button→ Control Panel→ Performance and
Maintenance→ Power Options.
2 Click the Power Schemes tab.
3 In the Power schemes drop-down menu, click Low Power Mode.
For more information on power management, see the Tell Me How help file.
To access the help file, see page 80.
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.
