	2. Keyboard (Interactive Test)
TrackPoint or	If the TrackPoint does not work, check the configuration in the ThinkPad
pointing device	Configuration program. If the configuration of the TrackPoint is disabled,
	select Enable to enable it.
	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. This symptom is not a hardware problem.
	No service actions are necessary if the pointer movement stops in a short period
	of time.
	If this does not correct the TrackPoint problem, continue with the following.

	3. If the test does not detect the error, run Memory Test - Full (Diagnostics).
Fan	1. Start Windows 98 and check the air turbulence at the louver near the power switch.
	2. Run the fan test in Other Devices (Diagnostics)
