    I've just noticed my system is no longer sleeping. I'll wake it up after closing the lid, and the battery is almost gone.

    It is trying to go to sleep, judging from the Event Viewer. I get:
    Code: 
    The system is entering sleep.

Sleep Reason: Button or Lid
    But this is followed immediately by:
    Code: 
    The driver \Driver\USBHUB3 for device USB\ROOT_HUB30\4&dbf172b&1&0 stopped the power transition.
    The USBHUB3 driver seems to correspond to "Universal Serial Bus controllers/USB Root Hub (xHCI)" in Device Manager, however, "allow the computer to turn off this device to save power" is ticked, and "allow this device to wake the computer" is unticked, and greyed-out.

    I've updated the BIOS, Thunderbolt firmware/drivers, USB3 drivers to the latest versions on the Dell site, but no change. Any suggestions?

    If it is not, set "Hibernate after" in Advanced power settings to Never, and do a hard reset (5 sec pwr button).

    Hibernate is turned off completely (via powercfg)

    Check if this condition happens to be caused by a prior event. I've had this situation when the 9550 was waking a couple of seconds after going to sleep or hibernation or even soft shutdown. Only a hard shutdown put it to sleep. Then it would sleep reasonably for a while while testing... but it would wake up in my backpack, and wouldn't stay in sleep again. In Event viewer I found that it woke up after an hour for auto switchover to Hibernate, but the hibernation failed, and it would enter a weird state.

    You can also try creating a new UEFI boot partition in BIOS, and move it to the top (mine got corrupted somehow once).

    I don't recall anything about this USB root hub, so you may have a different issue, or perhaps an USB device? Try debugging with the powercfg command + options in admin command prompt.

    Had this issue a few times but never looked that far into it as the fix that worked was to hold the power button down for 5 seconds to force the laptop off, but do this from the diagnostics to avoid corrupting windows, when the laptop is fully powered down hold D while tapping the power button then when the diagnostics starts hold the power button until it forces the power off.

    See if it helps.

    Exactly the same problem here !
    GoNz0 solution doesn't work on my XPS.

    I have had this problem twice now; the only solution that has worked for me is to re-flash the BIOS.
