[. . . ] Identifying low battery levels When a battery that is the sole power source for the computer reaches a low battery level, the battery light blinks. If a low battery level is not resolved, the computer enters a critical battery level, and the battery light blinks rapidly. The computer takes the following actions for a critical battery level: ● ● If Hibernation is enabled and the computer is on or in the Sleep state, the computer initiates Hibernation. If Hibernation is disabled and the computer is on or in the Sleep state, the computer remains briefly in the Sleep state, and then shuts down and loses any unsaved information. 72 Chapter 5 Power management Resolving a low battery level CAUTION: To reduce the risk of losing information when the computer reaches a critical battery level and has initiated Hibernation, do not restore power until the power lights turn off. Resolving a low battery level when external power is available ▲ Connect one of the following devices: ● ● ● AC adapter Optional docking device Optional power adapter Resolving a low battery level when a charged battery is available 1. Resolving a low battery level when no power source is available ▲ Initiate Hibernation. Resolving a low battery level when the computer cannot exit Hibernation When the computer lacks sufficient power to exit Hibernation, follow these steps: 1. Calibrating a battery Calibrate a battery under the following conditions: ● ● When battery charge displays seem inaccurate When you observe a significant change in battery run time Even if a battery is heavily used, it should not need to be calibrated more than once a month. NOTE: The battery charges whether the computer is off or in use, but it charges faster when the computer is off. Connect the computer to an AC adapter, optional power adapter, optional expansion product, or optional docking device, and then plug the adapter or device into external power. Leave the computer plugged into external power until the battery is fully charged. Click the battery meter icon in the notification area, and then click More power options. Record the Turn off the display and Put the computer to sleep settings listed in the On battery column so that you can reset them after the calibration. Change the Turn off the display and Put the computer to sleep settings to Never. Click the plus sign next to Sleep, and then click the plus sign next to Hibernate after. Record the On battery setting under Hibernate after so that you can reset it after the calibration. Step 3: Discharge the battery The computer must remain on while the battery is being discharged. The battery can discharge whether or not you are using the computer, but the battery will discharge faster while you are using it. — ● If you plan to leave the computer unattended during the discharge, save your information before beginning the discharge procedure. If you use the computer occasionally during the discharge procedure and have set energy-saving timeouts, expect the following performance from the system during the discharge process: ◦ ◦ ◦ The monitor will not turn off automatically. Hard drive speed will not decrease automatically when the computer is idle. [. . . ] CCM enables you to perform the following tasks: ● ● ● ● ● ● ● Collect hardware and software inventory across multiple platforms Prepare a software package and conduct impact analysis prior to distribution Target individual computers, workgroups, or entire populations of computers for deployment and maintenance of software and content according to policies Provision and manage operating systems, applications, and content on distributed computers from any location Integrate CCM with help desks and other system management tools for seamless operations Leverage a common infrastructure for management of software and content on standard computing devices across any network for all enterprise users Scale to meet enterprise needs 160 Chapter 15 Management and printing HP SSM (System Software Manager) HP SSM (System Software Manager) lets you remotely update system-level software on multiple systems simultaneously. When executed on a client computer, SSM detects versions of both hardware and software, and then updates designated software from a central repository, known as a file store. Driver versions that are supported by SSM are denoted with a special icon on the HP driver download Web site. To download the SSM utility or to obtain more information on SSM, see the HP Web site at http://www. [. . . ]
