Related service information Related service information This section provides information about the following: "Reset switch" "Service Web site" "Passwords" Power management features Reset switch The Reset switch resets the system (regardless of the microcode status) and forces the power off. Use this pushbutton to power off when power is not completely off or the microcode is in a hung state. For its location, see "Front view" on page 94. Service Web site When the latest maintenance diskette and the system program service diskette are available, a notice will be posted on http://pccbbs.raleigh.ibm.com/ Passwords As many as three passwords may be needed for any ThinkPad computers: the power-on password (POP), the hard disk password (HDP), and the supervisor password (PAP). When the power-on password (POP), the hard disk password (HDP), or the supervisor password (PAP) is used, the following situations may occur: If the PAP is used, the HDP is enabled automatically, but no HDP prompt appears. The HDP is set the same as the PAP. If the POP is the same as the HDP, the POP prompt appears, but the HDP prompt does not appear. If the POP is not the same as the HDP, both prompts appear. If a ThinkPad computer has an extra bay, it can support more than two HDPs. Then the following situations may occur: If the POP is the same as one of the HDPs (HDP-1 or HDP-2), a POP prompt appears. The passwords are different. If the POP is not the same as either of the HDPs (HDP-1 or HDP-2), both prompts appear. If the PAP is used, the HDP-1 or the HDP-2 is automatically enabled, but the HDP prompt does not appear. The HDP-1 or the HDP-2 are then set to the same password as the PAP. 22 ThinkPad 570 and 570E Hardware Maintenance Manual
