I have a dell inspiron 13 7368, running Ubuntu 16.04 Everything is fine and smooth except that it happened more than once that it just shuts down suddenly, like if you unplug the power without battery, it is always running on battery when this happens.

any suggestions ? where to look or what to test?

EDIT: syslog entries (last entry is after the crash)

  • Need details. Are you using Nvidia proprietary drivers? Have you applied updates for all packages? What are you doing when crash happens? I did have your problem for first month of Ubuntu 1604 on a Dell 5510. Updating Intel video driver along with many other updates has solved freezes. If you have consistent kernel panic, some folks here can help recover error files. In your /var/log folder, text logs should have evidence of crash cause. Look at messages files – pauljohn32 Sep 26 '16 at 3:33
  • no Nvidia. I had everything updated. not kernel panic, I checked that. about what I was doing.. more like everything.. I use my laptop almost all the time.. never shutdown.. more than 5 programs open at any time (Chrome, IDE, office, mail, terminal, etc..) most likely Chrome is active when it happens I'll edit to share the latest syslog entries, I believe it is clean – Geda Sep 27 '16 at 4:50
  • We need to see the part of /var/log/syslog that happened just before/during the shutdown. Cheers, Al – heynnema Sep 27 '16 at 13:08
  • Does this shutdown occur when it's plugged into AC power? Cheers, Al – heynnema Sep 27 '16 at 13:09
  • Please see my updated answer, below. Cheers, Al – heynnema Sep 27 '16 at 13:45

It sounds like a bad battery. But lets try and reset the power manager.

Unplug the computer from AC, and remove the battery (if it's removable). Hold down the power button for 10-15 seconds. Reinstall the battery and reconnect the AC adapter (if you wish) and see if that solves your shutdown problem.

You can also check the system log file by, in terminal, type more /var/log/syslog and find nearby the time that you had a shutdown. Look specifically for any temperature related messages. If found, it would indicate that your machine is overheating, causing the shutdowns.

There's also a BIOS (and a firmware) update available that might help. See http://www.dell.com/support/home/us/en/04/product-support/product/inspiron-13-7368-2-in-1-laptop/drivers, and select BIOS (or ALL) as the category.

Cheers, Al

  • Can you please explain exactly what this long press of power button does, looks like it worked for me on ubuntu 18.04 dell n7110 with phoneix bios A13 – Rajat Verma Dec 17 '18 at 4:39
  • @RajatVerma sometimes the power control circuitry gets confused, and the long press resets it. – heynnema Dec 17 '18 at 13:16
