I have a desktop PC running Windows 7 Pro x64. If I do a Windows shutdown while my Epson WF 3520 All in One Printer is powered on, it goes off for a few seconds then boots up again. This started after updating the BIOS from 0019 to 0124. There is a switch on the PC's power supply. If I flip it to Off just as the PC goes off, 3 seconds later, the power light will blink brightly (like it's trying to restart) then do one more dim blink. At that point, I can toggle the switch back and it will remain off. It powers on normally with the button on and all is well until the next time I turn my PC off.
Workaround:
If I turn the printer off before I issue the shutdown, it stays off like it should.
It appears like the newer BIOSs (0124 and 0125) are reacting to a signal from the USB port I have the printer connected to and awakening from a powered off state. I spoke with Epson's tech support and they hadn't heard of this. They suggested trying their printer on another PC. I know it works fine because it was connected to another PC before I bought a new one.
All of the BIOS and Drivers for DB85FL motherboard are up to date . Windows 7 is up to date and the Epson driver is as well. I tried all sorts of BIOS changes and set them back to the default as a last resort.
Has anyone else encountered this and identified a local change that I can make to have it go off and stay off when connected to a powered on printer?
Thanks
