Battery and Power Management This chapter gives information on using battery power. It also describes how the Power Management features works to save power.
Battery Pack The rechargeable battery pack supplies power to your Qbe when external power is not connected. 3 The average operating time of a battery pack is 2.5 hours for a Li-Ion battery pack. The operating time can be prolonged if Power Management is activated. However, actual operating time can vary, depending on several factors; these could be the Power Management settings, the software in use, the brightness of the display, and the system configuration.
You cannot initialize two battery packs at the same time. Recharging the Battery Pack To recharge the battery pack, connect the AC adapter to the computer and an electrical outlet. To ensure the battery pack is charged to its full capacity, it is advisable to keep the computer turned off during the recharging process. The battery is fully recharged when all four bars of the battery indicator glow and the frame stop flashing.
Checking the Battery Level The battery level cannot be measured physically. Any reading on a battery meter or gauge is only an estimation. This, however, could be less than accurate due to factors such as temperature and a long period of storage. If the difference between the displayed battery level and the actual operating time is too large, initialize the battery pack as described earlier in this chapter to correct the problem.
Additional Battery Pack There is danger of explosion if the battery is incorrectly replaced. Replace the battery only with the same or equivalent type recommended by the equipment manufacturer. Discard used batteries according to the manufacturer instructions. If you wish to prolong operating time on battery power while traveling, an optional extra fully charged battery pack is necessary.
4. Pull the battery pack out of the compartment. (diagram) Figure 3-1. Removing the Primary Battery Pack 5. Slide the new battery pack into the compartment. 6. Replace the compartment cover. Make sure the locking latch is in the locked position.
Low Battery When a single bar begins to flash in the battery indicator, battery power has reached the "Low” level and only ten minutes of computer operation remains. At this stage, make sure to save your data then connect the AC adapter or turn off the computer. Battery operating time depends on functions performed. If, for example, the audio subsystem, PC card, or disk drives are in use, then the battery expends itself sooner.
Power Management Your Qbe’s Power Management feature saves power by automatically reverting to low power mode when the system is inactive for some time. The computer returns to full power mode whenever activity is detected such as when a key is pressed. 3 This section describes how Power Management works. To customize Power Management, you need to run the SCU program. (See the "Power Management Menu” section in Chapter ? for instructions.
Low power mode work in the following way: Full Power Mode 1 to 16 minutes Global Standby Mode 2 to 14 minute Power-On-Suspend Mode 5 to 60 minutes Suspend-to-Disk Mode 1. 2. 3. In Global Standby mode, the CPU clock stops and several system devices enter lower power mode. In Power-On-Suspend mode, more system devices enter lower power mode. The power/suspend indicator ( ) lights amber in Power-On-Suspend mode. To end Power-OnSuspend mode, you need to press a key.
Manually Entering Low Power Mode In addition to the timer setup in the SCU program that causes the computer to enter lower power mode automatically, you can manually initiate lower power mode at any time in one of the following ways: 3 • By pressing [Fn]+[F1] This will activate Power-On-Suspend mode. If the computer remains in Power-On-Suspend mode until Suspend-to-Disk mode timer times out, the computer enters Suspend-to-Disk mode.
