is displayed at the lower left of the screen, press F1 to enter
the BIOS Setup Utility.

1. If two DIMMs are installed, remove one of them and run
Diagnostics --> Advanced Memory Tests.
2. If the problem does not recur, return the DIMM to its place,
remove the other one, and run the test again.
If the TrackPoint does not work, check the configuration as
specified in the BIOS Setup Utility. If the TrackPoint is disabled,
select Automatic to 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:
