Ubuntu

power issue - computer won't wake up from suspension

Asked by Yochai

Hello,

I would very much appreciate any help with a power issue on my lenovoG70 (Intel® Core™ i5-4210U CPU, GeForce 820M/PCIe/SSE2).

Even though I'm not very good in programming, I've been a huge fan of linux for many years! So I hope I could fix this issue without having to do sophisticated programming.

I've been using Linux Mint cinnamon 17, and yesterday I switched to Ubuntu 16.04 (because of a bug I got tired off). Everything works fine, except that when I put my laptop into suspend mode / hibernate, it won't wake up. It seems as the computer does wake up, but the screen stays black no matter what.
I've tried going back to mint, but the problem stayed. So I also tried mint 18, ubuntu 14, elementary os, and nothing helped. I googled and tried switching to kernel 4.4.8 and yet nothing helps.

Did I screw my hardware somehow?

Any suggestions? Maybe a specific driver for Lenovo g70?

Any help will be much appreciated!

Cheers

What does programming have to do with Linux use?

What is the output of:

sudo lshw -C display; lsb_release -a; uname -a

All the distributions you tried are Ubuntu with a slightly different set of applications. All the things doing the actual work are 100% the same.

Thank you actionparnship for you answer,

I actually realized as well that all theses distros are similar to ubuntu, so I switched to opensuse. I tried puting the comand "sudo lshw -C display; lsb_release -a; uname -a", but the system doesn't recognize it.

It tells me:

yochai@linux-r9tu:~> sudo lshw -C display;lsb_release-a;uname -a
sudo: lshw: command not found
If 'lsb_release-a' is not a typo you can use command-not-found to lookup the package that contains it, like this:
    cnf lsb_release-a

Anyway, the sleep mode/suspension mode, doesn't work here either. I had to turn off the laptop in the million time by long-pressing the power button, and it almost fried my computer.

This is really depressing, never had such a difficult time with linux.

Thanks though!

If you copy and paste the command it will work.

I tried again, it shows me this message:

Then you are using Suse and not Ubuntu.

You want the Suse forums.

Thanks, yes you are right, I was using opensuse.

Anyways - good news, I decided to go back to an older version of ubuntu - 12.04 and now it works!

Thank you once again.
