How do I get my computer to go into standby mode?


My system will no longer go into standby mode. I get an error message that reads:

"The device driver for the 'communications Port (com1)' device is preventing the machine from entering standby. Please close all applications and try again. If the problem persists, you may need to uopdate this driver."

I have closed all apps, updated the driver and the error continues.

I attempted to remove com1. I then get an error message regarding my modem conflicting. I delete and reinstall my moden driver and the com1 error returns.

????? Help,
