It changes the processor speed to find the best balance between your computing performance and power consumption needs. Higher speeds enjoy better performance, while slower speeds conserve more power.In Windows XP, the processor's performance level depends on the Power Scheme you select (see Power Options Properties, section 6.1.3). You do not need to make any further adjustments to set the performance level. Each preset power scheme has different time-out settings for entering standby mode, hibernate mode, turning off the display, and turning off the hard drive. For example, the Portable/Laptop mode automatically changes SpeedStep modes depending on if you are running the computer on AC power or batteries in order to prolong battery usage while still providing optimal performance. You can also individually alter and save each of these settings and schemes if desired. 第 4 頁，共 8 頁The Power System2003/8/15file://C:\WINDOWS\TEMP\~hh970C.htm

Battery PerformanceUsing a battery lets you work with your notebook without connecting it to an electrical outlet. Your notebook comes with one 8-cell Li-Ion battery pack installed, which will give you more than 300 charging/discharging cycles. The performance of the battery can vary, depending on operating conditions. Your battery may last less time if you are running power-intensive programs, playing CDs or DVDs, using PC cards or have high high display-brightness settings. The Power Management Options can be set to alert you when the battery charge is low. Ensure any battery you use is compatible. Failure to do so may risk fire or explosion. For more details on purchasing compatible batteries, talk to your notebook retailer. Batteries should never be disposed of with household waste. Contact your local waste disposal or environmental agency for advice on disposing of used lithium-ion batteries.TopChecking the Battery ChargeBattery Status Indicator behaviorCharging blinks greenFully Charged solid greenDischarging offLow Battery (10%) solid amber -> approximately 12 minutes leftCritical Low blinks amber -> approximately 3 minutes left; system beepsTop Power MeterThe power meter indicates the remaining battery charge.
