Solving computer problems

Solution:

Make sure that the TrackPoint and the touch pad are set to Automatic in the ThinkPad Configuration Program. Then detach the mouse or the pointing device, and try using the TrackPoint and the touch pad. If the TrackPoint and the touch pad work, the error might be due to the mouse or the pointing device.

Make sure that the cable for the mouse or the pointing device is securely connected to the ThinkPad Dock II, ThinkPad Mini Dock, or the ThinkPad Port Replicator II.

If your mouse is incompatible with the PS/2 mouse, disable the

TrackPoint, using the ThinkPad Configuration Program.

Note: For more information, see the manual supplied with the mouse.

Problem:

The mouse buttons do not work.

Solution:

If your ThinkPad computer has the TrackPoint only, this problem may occur.

Change the mouse driver to Standard PS/2 Port Mouse, and then reinstall PS/2 TrackPoint. Drivers are provided in the C:\IBMTOOLS\DRIVERS directory on your hard disk drive. If your hard disk drive does not contain device drivers, refer to the ThinkPad Web site. For access to this Web site, press the Access IBM button and open Access IBM.

Problem:

The scrolling or magnifying glass function does not work.

Solution:

Check the mouse driver in the Device Manager window, and make sure that the PS/2 TrackPoint driver is installed.

Standby or hibernation problems

Problem:

The computer enters standby mode unexpectedly.

Solution:

If the processor overheats, the computer automatically enters standby mode to allow the computer to cool and to protect the processor and other internal components. Also, check the settings for standby mode, using Power Manager (Battery MaxiMiser on some models).

Problem:

The computer enters standby mode immediately after Power-on self-test (POST) (the standby indicator light turns on).
