Hello all,
I am recieveing an error on one of the laptops here at work. The error is when the computer tries to enter stand-by mode. The error is as follows: "The device driver for the communication port (COM1) device is preventing the machine from entering stand-by. Please close all applications and try again. If the problem presists, you may need to update this driver". I have the most up to date driver. I have disabled the COM1 port in order to see if it will work. It will now give meanother error. It is basically the same as the first error, but it specifies the modem instead of the com port. I have tried to repair windows (as instructed by Dell). and I have searched for updates on the drivers. Nothing has worked. PLEASE HELP!!!

Assuming your modem is not working.... try to disable any wireless device you may have on the laptop. Some of these "networking" cards really use a serial interface to communicate.

Do you by any chance have Quicken installed on the pc? There have been quite a few complaints about this and Intuit does have a fix.

If this is the case check this link:

or go to Intuit's site and search for "com1 standby".

There may not be a way to correct this? For example, I have an HP Laserjet 3100 printer connected to LPT1 and as long as it's connected to that or any other port on my computer, according to Microsoft/Hewlett Packard the're working on the problem and I will just have to live with the fact that for now my computer will not be capable of entering suspend mode until (if ever) a fix can be provided. Just because you don't have any devices "physically" connected to a port on your laptop does not mean it's not actually being used! Many laptops for example have infrared capabilities and utilize it to link to other devices such as networks or..? If the laptop has infrared enabled in the bios it will usually have one of the com ports assigned to it. Look at the port assignments from the Windows Device Manager/Ports and Printer Settings/Ports to see what actually connected to and/or assigned to ports in the system. Looking at Printer/Properties/Ports it will show all the various ports and assignments on the system, including any "virtual" ports/assignments which very well could be the source of the problem and will not show up in the Windows Device Manager. Hope this helps some, Good Luck!
