Helping people with computers... one answer at a time.
Because of an interaction with Quicken 2000, your machine may not be able to enter standby.
Why is 'Communications Port ... preventing the machine from entering standby'?

The full message is typically "The device driver for the Communications Port COM1 device is preventing the machine from entering standby".

Apparently there's an interaction with Quicken 2000. This article out on the Dell support forums has more details.

Leo A. Notenboom has been playing with computers since he
was required to take a programming class in 1976. An 18 year career as a programmer at Microsoft soon followed.
After "retiring" in 2001, Leo started Ask Leo! in 2003 as a place for answers

Thank you very much. It worked. I am using Quicken 2000. You know I even tried to look for which driver is associated with which COM port number under Device Manager....I always thought that it could be a hardware like a modem or infrared which gets assigned a COM port and maybe there is a conflict between two devices.

i get the message:
the device driver for the 'communications port (com1)' device is preventing the machine form entering standby. please close all applications and try again. if the problem persisists you may need to update this driver.
i remember using quicken on this computer, but i thought i deleted it. and i can't find quicken in any of the files on my computer.
i installed a program called lightsource, which is a series of geometrical graphics/colours/designs.
then i noticed problems with this computer using windows xp home edition service pack three, version 2002.
any suggestions to fix this problem? i like the computer to go into standby when i'm not using it for 30 minutes or so.
thanks,
jw

I do not use the download function of quicken so as a test I renamed the driver files that quicken uses. These files are called "mrtRate" and found under the subdirectories system32 and system32/drivers. Bingo, fixed the problem.
