If the TrackPoint is disabled, select Enableto enable it. After you use the TrackPoint, the pointer may drift on the screen for a short time. This drift can occur when a slight, steady pressure is applied to the TrackPoint pointer. This symptom is not a hardware problem. If the pointer stops after a short time, no service action is necessary. If enabling the TrackPoint does not correct the problem, continue with the following: vInteractive Tests-->Mouse Hard-disk driveDiagnostics-->Fixed Disks (continued) Product overview ThinkPad A21e, A22e, i 180043

Fn key combinations The following table shows the function of each combination ofFnwith a function key. TheFnkey works independently from the operating system. Key combinationDescription Fn+F1Reserved. Fn+F2Reserved. Fn+F3Turn off the computer display, leaving the screen blank. To turn the computer display on again, press any key or the TrackPoint stick. Fn+F4Turn standby mode on. To return to normal operation, press the Fn key independently, without pressing a function key. Notes: 1. This mode is calledsuspend modein Windows 95 and Windows NT. 2. In Windows 2000, this combination of buttons functions as a sleep button. You can change the settings so that pressing it puts the computer into hibernation mode or even shut the computer down.

Symptom-to-FRU index The symptom-to-FRU index in this section lists symptoms and errors and their possible causes. The most likely cause is listed first, in boldface type. Note:Do the FRU replacement or other actions in the sequence shown in the column headed“FRU or action, in sequence.”If replacing a FRU does not solve the problem, put the original part back in the computer. Do not replace a nondefective FRU. This index can also help you determine, during regular servicing, what FRUs are likely to need to be replaced next. A numeric error is displayed for each error detected in POST or system operation. In the displays,ncan be any number. If no numeric code is displayed, check the narrative descriptions of symptoms. If the symptom is not described there, go to“Intermittent problems”on page 52. NoteFor an IBM device not supported by diagnostic codes in the ThinkPad notebook computers, see the manual for that device. Numeric error codes Symptom or error FRU or action, in sequence 0175 Bad CRC1, stop POST task— The EEPROM checksum is not correct.System board. 0187 EAIA data access error—The access to EEPROM has failed.System board. 0188 Invalid RFID serialization information area or bad CRC2 —The EEPROM checksum is not correct.System board. 0189 Invalid RFID configuration information area—The EEPROM checksum is not correct.System board.
