Ubuntu zesty hangs at SMP configuration when running on battery

Asked by fabio.hipolito on 2017-05-15

Ubuntu 17.04 always hangs at startup when running on battery power, if plugged to power startup runs perfectly.
No problems with Ubuntu 16.04.

By booting via recovery it is possible to verify that start up always hangs up at:
"x86: Booting SMP configuration"

To the best of my knowledge I could not recover this information by other means than a photo

The machine in question is a Lenovo P50 running ubuntu-gnome
$ uname -a
Linux nebulosa 4.10.0-21-generic #23-Ubuntu SMP Fri Apr 28 16:14:22 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
The problem is also present with kernels 4.10.0-20-generic and 4.10.0-19-generic.

Do you have the latest BIOS?

No, the BIOS version is N1EET41W (1.15 ) released on 12/31/2015.

To the best of my knowledge Lenovo only provides software to update BIOS via Windows (and my machine runs Linux only).

Do you need more information?

Hi,

after updating the BIOS to the lastest version, this problem vanished.

Current BIOS version N1EET66N (1.39)

For those, like me, who do not know how to update the BIOS in a Linux only machine, follow the instructions at 'site' and also the recommendations below

site => https://workaround.org/article/updating-the-bios-on-lenovo-laptops-from-linux-using-a-usb-flash-stick/

This version of the BIOS for Lenovo P50 can be found here

Make sure that your laptop is connected to the power and not to a dock, the BIOS update utility will not run in that configuration

Also verify that your current BIOS setup is compatible with the recommendations regarding "Affected Setup menu items" in the instructions in the README file (n1eur23w.txt). I used "[Disabled] case" configuration.
