Exception: If only an SVP is installed, the password prompt does not appear when the operating system is booted.
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.
The system administrator then provides the user HDP to the system user. If it has, it can be used for access to the hard-disk drive. The hard-disk drive can be replaced for a scheduled fee. 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.
Turn on the computer and wait until the POST ends. After the POST ends, the password prompt does not appear. The POP has been removed. Reinstall the backup battery and the battery pack.

To reduce power consumption, the computer has three power management modes: screen blank, standby, and hibernation. When the computer enters standby mode, the following events occur in addition to what occurs in screen blank mode:. Even if you do not set the low-battery alarm, the charge indicator notifies you when the battery is low, and then the computer enters the power-saving mode automatically.
This default low-battery behavior is independent of the operating system; so if you have set the low-battery alarm, the computer may not do what you specified. It chooses either your setting or the default setting, whichever is appropriate.
If you are using the ACPI operating system, only the low-battery alarm is available. To cause the computer to return from standby mode and resume operation, do one of the following:. Also, the computer automatically returns from standby mode and resumes operation in either of the following events:. Note: The computer does not accept any input immediately after it enters standby mode. Wait a few seconds before taking any action to reenter operation mode. Note: If the computer enters the hibernation mode while it is docked to the docking station, do not undock it from the docking station before resuming normal operation.
If you do undock it and then try to resume normal operation, you will get an error message, and you will have to restart the system. Also, the computer goes into hibernation mode automatically in either of the following conditions:.
When the power is turned on, the computer returns from hibernation mode and resumes operation. The hibernation file in the boot record on the hard-disk drive is read, and system status is restored from the hard-disk drive. Use the following procedures as a guide in identifying and correcting problems with the ThinkPad computer.
Note: The diagnostic tests are intended to test only IBM products. The use of non-IBM products, prototype cards, or modified options can lead to false indications of errors and invalid system responses. Identify the failing symptoms in as much detail as possible. Verify the symptoms. Try to re-create the failure by running the diagnostic test or by repeating the operation.
You can detect errors by running the diagnostics test included in PC-Doctor. This section is an overview of the procedure. For some possible configurations of the computer, PC-Doctor might not run correctly. Note: When you initialize the computer configuration, some devices are disabled, such as the serial port. If you test one of these devices, you will need to enable it by using PS2. PC-Doctor cannot be used to test a device that is in the docking station, even if the computer supports the docking station.
To test the Ultrabay device, install it in the Ultrabay Plus slot of the computer. Note: In the following procedure, you can select an item not only with the arrow keys, but also with the TrackPoint.
Instead of pressing Enter, click the left button. Insert the PC-Doctor disk into the diskette drive; then power on the computer. On the first screen, select the model and press Enter.
Follow the instructions on the screen. The main panel of PC-Doctor appears. Select Diagnostics with the arrow keys, and press Enter. Each key should be held down for at least 2 seconds; otherwise, it cannot be sensed.
Run the applicable function test. If there is a problem, PC-Doctor shows messages describing it. To exit the test, select Quit — Exit Diag. To cancel the test, press Esc. Check that power is supplied when you power on the computer. Disconnect the ac adapter and install the charged battery pack. Check that the battery pack supplies power when you power on the computer. If you suspect a power problem, see the appropriate one of the following power supply checkouts:. Unplug the ac adapter cable from the computer.
Measure the output voltage at the plug of the ac adapter cable. See the following figure:. If the voltage is not correct, replace the ac adapter. If the voltage is acceptable, do the following: v Replace the system board. Note: Noise from the ac adapter does not always indicate a defect. Perform operational charging. If the battery status indicator or icon does not turn on, remove the battery pack and let it return to room temperature.
Reinstall the battery pack. If the charge indicator or icon still does not turn on, replace the battery pack. If the charge indicator still does not turn on, replace the system board. Then reinstall the battery pack. If it is still not charged, go to the next section. This protects the battery pack from being overcharged or from having a shortened life.
To check the status of 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 , 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 charge.
Remove it from the computer and leave it at room temperature for a while. After it cools down, reinstall and recharge it. Note: Recharging will take at least 3 hours, even if the indicator does not turn on.
The resistance must be 4 to 30 K. If the resistance is not correct, replace the battery pack. If the resistance is correct, replace the system board.
Power off the computer, and unplug the ac adapter from it. Turn the computer upside down. Measure the voltage of the backup battery. See the following figure. Welcome to ManualMachine.
