Note: Noise from the AC adapter does not always indicate a defect. 21 Lenovo IdeaPad Z380/Z480/Z485/Z580/Z585 Hardware Maintenance Manual Checking operational charging To check whether the battery charges properly during operation, use a discharged battery pack or a battery pack that has less than 50% of the total power remaining when installed in the computer. If the battery status indicator or icon does not light on, remove the battery pack and let it return to room temperature. If the charge indicator or icon is still off, replace the battery pack. If the charge indicator still does not light on, replace the system board. If it is still not charged, go to the next section. Checking the battery pack Battery charging does not start until the Power Meter shows that less than 95% of the total power remains; under this condition the battery pack can charge to 100% of its capacity. This protects the battery pack from being overcharged or from having a shortened life. To check your battery, move your cursor to the Power Meter icon in the icon tray of the Windows® taskbar and wait for a moment (but do not click it), and the percentage of battery power remaining is displayed. To get detailed information about the battery, double-click the Power Meter icon. Note: If the battery pack becomes hot, it may not be able to be charged. Exception: If only an SVP is installed, the password prompt does not appear when the operating system is booted. Power-on password A power-on password (POP) protects the system from being powered on by an unauthorized person. The password must be entered before an operating system can be booted. Hard-disk password There are two hard-disk passwords (HDPs): + User HDP - for the user + Master HDP - for the system administrator, who can use it to get access to the hard disk drive even if the user has changed the user HDP Attention: If the user HDP has been forgotten, check whether a master HDP has been set. If no master HDP is available, neither Lenovo nor Lenov authorized service technicians provide any services to reset either the user or the master HDP, or to recover data from the hard disk drive. A supervisor password (SVP) protects the system information stored in the BIOS Setup Utility. The user must enter the SVP in order to get access to the BIOS Setup Utility and change the system configuration. Attention: If the SVP has been forgotten and cannot be made available to the servicer, there is no service procedure to reset the password. The system board must be replaced for a scheduled fee. Supervisor password 24 Related service information Power management Note: Power management modes are not supported for APM operating system. To reduce power consumption, the computer has three power management modes: screen blank, sleep (standby), and hibernation. Screen blank mode If the time set on the "Turn off monitor" timer in the operating system expires, the LCD backlight turns off. To end screen blank mode and resume normal operation, press any key. Sleep (standby) mode When the computer enters sleep (standby) mode, the following events occur in addition to what occurs in screen blank mode: · The LCD is powered off. In certain circumstances, the computer goes into sleep (standby) mode automatically: · If a "suspend time" has been set on the timer, and the user does not do any operation with the keyboard, the hard disk, the parallel connector, or the diskette drive within that time. · If the battery indicator is amber, indicating that the battery power is low.
