Do not enter hibernation mode or power off the computer when this indi- cator is on. (4) Numeric lock Green The numeric keypad on the keyboard is enabled.
1. Obtain the failing symptoms in as much detail as pos- sible. 2. Verify the symptoms by attempting to recreate the failure by running the diagnostic test or by repeating the same operation. Note: To run the diagnostics, refer to “Running the Diagnostics” on page 42 3.
CAUTION: Make sure that the diskette does not have more than one label attached to it. Multiple labels can cause damage to the drive or can cause the drive to fail. Do the following to select the test device. See “Running the Diagnostics” on page 42 for details.
Fan ASM Checkout To check the Fan ASM, do the following: 1. Boot from the diagnostics diskette and start the Fan ASM Diagnostics. 2. Follow the description in the window. If the test detects the Fan ASM problem, replace it. Keyboard and Auxiliary Input Device Checkout Note: Remove the external keyboard if the internal key- board is to be tested.
Memory errors might stop system operation, show error messages on the screen, or hang the system. Use the following procedure to isolate memory problems: 1. Boot from the diagnostics diskette and start the PQA program (please refer to “PQA System Diagnostics” on page 42).
3. Disconnect the AC Adapter and install the charged battery ASM; then check that power is supplied by the battery ASM. If you suspect a power problem, refer the the appropriate power supply check lis.
Perform operational charging. If the battery status indicator does not turn on, remove the Battery ASM and let it return to room temperature. Reinstall the Battery ASM. If the charge indicator still does not turn on, replace the Battery ASM. If the charge indicator still does not turn on, replace the DC-DC & BATT board, then the planar board.
If this does not correct the TrackPoint problem, continue with the following. After you use the TrackPoint, the pointer drifts on the screen for a short time. This self-acting pointer movement can occur when a slight, steady pressure is applied to the TrackPoint pointer.
The specified time has elapsed. Battery low occurs and hibernation conditions are insufficient. Note: When battery is low, the battery status indi- cator blinks orange. The computer is ejected from the ThinkPad Port Replicator with Advanced Etherjet Feature.
Notes: 1. In the ThinkPad Configuration program, the computer can be set to suspend when docked. 2. The computer cannot enter hibernation mode when it is attached to the ThinkPad Port Replicator with Advanced Etherjet Feature. Events that cause the computer to enter hibernation mode: Hibernation mode requested by function key (Fn+F12).
