[Bug 1552985] Re: [Dell Inspiron 14 3000 Series] System hangs on poweroff
Today I updated my laptop's BIOS to A12 version, and now I'm able to shutdown the computer without problems. On the BIOS update details (http://www.dell.com/support/home/mx/es/mxbsdt1/Drivers/DriversDetails?driverId=RCK0N&fileId=3543381893) a fix and an enhancement are mentioned: Fixes - Modify the output value of memory module manufacturer ID (from SPD) to hexadecimal ID. Enhancements - Update IO define for FreeBSD OS. Don't know which one fixes the shutting down problem.

I tried a Live USB using the Lubuntu 16.04 iso. Hardware: Dell Inspiron 1545 laptop; Core2Duo; 64-bit, 4 GB RAM; USB 2 currently running Lubuntu 14.04 fully updated; uname -a: Linux vasa1-Inspiron-1545 3.13.0-83-generic #127-Ubuntu SMP Fri Mar 11 00:25:37 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux I used mkusb version 10.5.1 (http://ppa.launchpad.net/mkusb/ppa/ubuntu/ trusty/main amd64 Packages) to make the Live USB on an 8 GB Transcend USB 2 pendrive. If the Live USB is made without persistence, while everything runs fine, shutdown doesn't work. The screen blanks and a cursor flashes at the top left corner of the screen. I can wait for a few minutes but still nothing happens. I need to long-press the laptop's power button to shut down. However, I can confirm that using the same version of mkusb and iso to create a persistent Live USB, the shutdown is normal. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1552985 Title: [Dell Inspiron 14 3000 Series] System hangs on poweroff To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1552985/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1552985] Re: [Dell Inspiron 14 3000 Series] System hangs on poweroff
Booted via grub-n-iso shutdown works for me, but not when the pendrive was created by cloning the current Lubuntu Xenial i386 daily iso file, xenial-desktop-i386.iso Today I tested with USB-creator-gtk 0.3.2 and mkusb, but can get the same result with other cloning tools, e.g. gnome-disks, dd. In other words, my live drive is affected when booted from a cloned system, but not from a grub-n-iso system made from the same iso file. I suspect that this bug is the same or closely related to the bug that also affects virtual machines, https://bugs.launchpad.net/ubuntu/+source/casper/+bug/966480 It is described as a race condition by Chris Bainbridge: https://bugs.launchpad.net/ubuntu/+source/casper/+bug/966480/comments/58 -o- Details: I tested this in a laptop bought 2013 (that I am often using for iso testing), http://www.toshiba.se/laptops/satellite-pro/c850/satellite-pro-c850-19w/ and in a desktop computer with the following motherboard bought 2008, http://www.asus.com/Motherboards/M2NVM_DVI/ A Sandisk Cruzer blade 4 GB USB drive cloned to a 'live-only' system with USB-creator-gtk 0.3.2 and mkusb is affected by this bug in both those computers. The same USB drive made into a grub-n-iso system with the same Lubuntu daily iso file according to the link http://ubuntuforums.org/showthread.php?t=2259682&p=13302278#post13302278 or made into a persistent live drive with mkusb according to this link https://help.ubuntu.com/community/mkusb/persistent can be shut down or rebooted properly (so these systems booted via grub are not affected).
