Cyril Soler, to clarify, if/when you had Windows installed on the laptop, if you didn't utilize the WORKAROUNDs would it suspend/resume successfully?

What's the difference?? There's a key in the USB port in the - first case. So I tried suspend/resume with the *installed* version when - a USB key is present: it works. + WORKAROUND: + 1) Resume works perfectly when any USB key is plugged in. + 2) Enable "USB Wake support" in the BIOS. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1617599 Title: Resume from suspend causes reboot, except if USB key is plugged in To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1617599/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
