I try and put my computer in standby mode and it wont let me. The error I get is : 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 update this driver.
I have already tried updating the driver and it still does not want to go into standby. Please help because I need to keep this computer on.
