Don't touch the TouchPad while the notebook is rebooting or resuming from
Standby mode. If this happens, try the following: press a key on the keyboard to
restore normal operation.
If an external mouse is connected, the built-in pointing devices are normally
disabled. You can change this setting with the BIOS Setup utility.
Restart the notebook. Select Start > Turn Off Computer > Restart.
If the TouchPad moves the pointer or cursor while you type
Press the TouchPad on-off button to turn off the TouchPad while you type.
If a PS/2 scroll mouse doesn't work

Setup utility, make sure the External Pointing Devices option in the System
Devices menu is set to Auto. See "Configuring the Notebook" in this chapter.
Suspend or shut down the notebook before you attach the scroll mouse, so that it
will be detected properly.
If you want to use the TouchPad again, you must suspend or shut down the notebook
before you detach the scroll mouse.
