Ubuntu – Ideapad 300 suspend not working on 16.04

16.04lenovosuspend

I was unable to get my Ideapad 300 running properly with 14.04(no wifi and lan not functioning), so I decided to try LTS 16.04.

Everything works well untill I tried going to suspend mode. Either when I closes my laptop lid or I click suspend. The screen just when off and did nothing to suspend. There is no way for me to recover the laptop from the state unless I press the power button long enough to shut it down and then power it back again.

Best Answer

It's seems that it is a 4.4.0 kernel bug, installing 4.4.8 solves the problem. You can either wait for a 4.4.0 kernel fix, or install the 4.4.8 kernel.

I recommand waiting for 4.4.0 fix, but i installed 4.4.8 and i've seen no problem whatsoever.

Execute following commands in order to install 4.4.8 kernel:
