djpumpkin Posted July 17, 2012 Share Posted July 17, 2012 I am wondering if there is a way to prevent usb drives from being disconnected when my D630 sleeps? At the moment when the machine wakes the drive is unmounted and I get a warning message telling me the drive was not put away properly. This happens on battery and mains power.

Administrators Hervé Posted July 17, 2012 Administrators Share Posted July 17, 2012 Yes, the USB ports are not electrically fed when the computer goes to sleep and, consequently, cannot supply 5V to connected devices. Not really a surprise, it is an expected behaviour during an energy-saving mode after all. This can be somehow/partially controlled in the BIOS. If you enable the USB wake feature, the USB ports will remain electrically fed when the computer is connected to the mains but not when operating on the battery.

djpumpkin Posted July 18, 2012 Author Share Posted July 18, 2012 Thanks Hervé I did find that setting in the bios but it seemed to have no effect - I've since found that the USB key I was using to test it with was defective. Now - when on power supply - USB ports are kept alive when sleeping / waking. Great! Link to comment Share on other sites More sharing options...
Administrators Hervé Posted July 19, 2012 Administrators Share Posted July 19, 2012 Pity this does not work on the D620. If you enable Wake on USB, the D620 won't go to sleep at all (or it does, only to wake up immediately). Link to comment Share on other sites More sharing options...
