When you attempt to place your computer in Standby mode, you may receive the following error message:
If you click OK, close all running programs, and try to use Standby mode again, you may still receive the same error message.
Your computer cannot go on standby because a device driver or program won't allow it. Close all open programs, and then try again.
This behavior can occur if an Epson Stylus 740 Universal Serial Bus (USB) printer is connected to your computer. There is a conflict with the third-party Epson printer drivers.
To work around this issue, unplug the printer from the USB port before placing your computer in Standby mode. When you need to print, plug the printer back in.
