Supervisor and hard disk passwords: The supervisor password (PAP) and the hard disk password (HDP) are security features that are used to protect the system and the hard disk data from unauthorized access. No overriding capability is provided. If only a hard disk password is set, you must get the password from its owner in order to run diagnostic tests and perform service. If both the supervisor password and the hard disk password are set, you can enter Easy-Setup by pressing the Enter key or by entering the power-on password at the supervisor password prompt. In this case, the Password, Start up, Network, and Initialize or ...

Power management features To reduce power consumption, the computer has three power management modes: Standby mode: In standby mode, the following occurs: Ÿ The LCD backlight turns off. Ÿ The hard disk drive motor stops. Ÿ The speaker is muted. Note: Standby mode in Windows 98 is called suspend mode in Windows 95. To enter standby mode, press Fn + F3. To end standby mode and resume normal operation, press any key. Suspend mode: When the computer enters suspend mode, the following events occur in addition to what occurs in standby mode: Ÿ The LCD is powered off. Ÿ The hard disk drive is powered off. Ÿ The CPU stops. Su ...

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.

correcting problems with the ThinkPad computer. Note: The diagnostic tests are intended to test only IBM products. The user of non-IBM products, prototype cards, or modified options can lead to false indications of errors and invalid system responses. 1. Identify the failing symptoms in as much detail as possible. 2. Verify the symptoms. Try to re-create the failure by running the diagnostic test or by repeating the operation. Testing the computer The ThinkPad computer has a test program called PC-Doctor DOS (hereafter called PC-Doctor). You can detect errors by ...

because the computer fails only when the AC Adapter is used: Ÿ If the power problem occurs only when the port replicator is used, replace the port replicator. Ÿ If the power-on indicator does not turn on, check the power cord of the AC Adapter for correct continuity and installation. Ÿ If the computer does not charge during operation, go to “Checking operational charging.” 1. Unplug the AC Adapter cable from the computer and measure the output voltage at the plug of the AC Adapter cable. See the following figure: (16 - 10 V) If the voltage is not correct, replace the AC Adapter. If the voltag ...

does not start until the Fuel Gauge 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. Note: The battery pack might not be able to charge when it is hot. In that case, remove it from the computer and leave it at room temperature for a while. After it cools down, reinstall and recharge it. Do the following: 1. Power off the computer. 2. Remove the battery pack and measure the voltage between battery terminals 1 (+) and 4 (−). See t ...

intermittently when PC Card devices are used through a port replicator with PC Card slots, suspect an a problem with over-current. Some PC Card devices use more power; if the maximum use of each device occurs simultaneously, the total current will exceed the limit, causing a power shutdown. Isolate this problem by removing one of the devices, and using the computer under the same condition. If a power shutdown occurs, you have found the cause of the problem. If not, do this procedure for all the other devices until you determine the cause. Product overview This section describes the following p ...
