My lenovo z50-70 is not resuming after i put the laptop in hibernation mode.

It gives a black screen on resume. I tried a solution - https://askubuntu.com/a/436389/411863

but it didn't work out.

ram-4 Gb swap partition size - around 10 Gb

Output for sudo blkid

  • Please edit your question and add there some information. Do you have a swap partition? What is its size? What is size of RAM? Add output of "sudo blkid" , "cat /etc/initramfs-tools/conf.d/resume" and "cat /etc/fstab"

  • Output for the last 2 is giving 'no such file or directory'. May 20, 2015 at 6:55
  • Do not retype commands, but copy them and paste to terminal. No quotes there.

[WORKAROUND]

It's possible disable Nvidia graphics under BIOS in Lenovo laptops like Z40-70.

To do procede:

  1. Press FN + F2 to in BIOS Configuration
  2. Under Configuration in Graphic Device change

    Discrete

to

UMA Only

This will disable NVIDIA graphics and Suspend will works on Debian, Ubuntu and derived Linux flavors. Not's the best, but is a option.

Found the solution on another forum. Technically speaking Z50-70 has two GPU's, Intel & nvidia. If nvdia is the default GPU, suspend and hibernate will have issues.

  1. Run "nvidia-settings" on terminal.
  2. In "PRIME Profiles" tab, select the GPU as "Intel" instead of "NVIDIA".
  3. Save and restart your machine.

  • Before you do the above, first try this answer given on an another question. That worked for me (Lenovo Z50 70), which isn't disabling the NVidea
