I installed mint on my laptop. All works fine, except suspend (sleep in windows). When I push that button on my laptop, the display is powered of and that's all. The laptop is still working. My model is Extensa-2511. I searched for information via Google but nothing helped me.

My system is:

  • Please run whatever command gave that output (looks like lshw) with LC_ALL=C. For example LC_ALL=C sudo lshw -C display. That way, the output will be in English. – terdon Sep 6 '16 at 12:00

I've solved this issue by installing new linux kernel "4.5.2-040502-generic" following this guidelines:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1574125/comments/26

Install new kernel (4.5.2):

cd /tmp

wget \
kernel.ubuntu.com/~kernel-ppa/mainline/v4.5.2-wily/linux-headers-4.5.2-040502_4.5.2-040502.201604200335_all.deb \
kernel.ubuntu.com/~kernel-ppa/mainline/v4.5.2-wily/linux-headers-4.5.2-040502-generic_4.5.2-040502.201604200335_amd64.deb \
kernel.ubuntu.com/~kernel-ppa/mainline/v4.5.2-wily/linux-image-4.5.2-040502-generic_4.5.2-040502.201604200335_amd64.deb

sudo dpkg -i linux-headers-4.5*.deb linux-image-4.5*.deb

Reboot your system and try if suspend works.

In case something goes wrong with new kernel (4.5.2) reboot your computer and select Advanced options for Linux Mint 18 Cinnamon 64-bit in boot menu, then select your old kernel (4.4.0-21).

Go to update manager and click on view and install the latest version of kernel in my case that is 4.4.0-57
