Keyboard/Pointing Device Locks up

[Guest john454]

I have a laptop running Windows XP Pro.

 

When the laptop is undocked, and I boot up the machine, everything

works until I get on the sign on screen....both the keyboard works,

and the touchpad/mouse. I can wait 10 min or so at the sign on screen

and everything is fine.

 

Once I do a ctrl-alt-del and logon, 50% of the time, the keyboard and/

or touchpad/mouse will lock up and stop working. The only way to fix

it is by rebooting and hoping on the reboot there are no issues.

 

A look in event viewer shows the following message:

 

Event ID 7000 - The parallel port driver service failed to start due

to the following error: The service cannot be started, either because

it is disabled or because it has no enabled devices associated with

it.

 

This laptop does not have a parallel port.

 

Any thoughts how to resolve it?

 

Thank you
