LED Problem Action
TEMP The system or the system
component temperature has
exceeded a threshold level. A
failing fan can cause the TEMP
LED to be lit.
1. Make sure that the heat sink is seated correctly.
2. Determine whether a fan has failed. If it has, replace it.
3. Make sure that the room temperature is not too high.
4. Make sure that the air vents are not blocked.
5. Make sure that the heat sink, the fan on the adapter, or
the optional network adapter is seated correctly. If the fan
has failed, replace it.
6. If the failure remains, go to http://www.ibm.com/

LED might also be lit.
1. Reseat the failing fan, which is indicated by a lit LED
near the fan connector on the system board.
2. Replace the failing fan.
BOARD An error occurred on the system
board.
1. Check the LEDs on the system board to identify the
component that caused the error. The BOARD LED can be
lit due to any of the following reasons:
v Battery
v (Trained technician only) System board
2. Check the system-error log for information about the
error.
3. Replace the failing component:
v Battery
