Lenovo Z360 occasionally does not suspend, cold up entirely

I have a new Lenovo Z360 laptop computer. Concerning 1 in 5 times, as opposed to putting on hold when I close the laptop computer cover, the screen goes empty and also the equipment ices up and also remains on, with the follower operating. I need to tough - boot then, which draws. I have not had the ability to limit the circumstance, specifically. This laptop computer does not have the NVidia card, simply the Intel video. I've switched off desktop computer results which really did not aid. It has actually taken place while connected in and also not connected in.

Update : Upgraded to Ubuntu 11.10 and also this concern still takes place.

Debug notes (per https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume) :

There are no blinking caps lock lights or comparable.

Establishing the boot param no_console_suspend and afterwards switching over to VT1 and also running the commands setfont /usr/share/consolefonts/Uni1-VGA8.psf.gz and also sudo pm-suspend will certainly cause suspend with this concern, yet there is no message result past the last command.

The computer system additionally ices up on closure (without in fact closing down) right after publishing Power Down on the console.

This is a well-known bug with suspend, and also however there appears to be no solution for it yet (regarding I recognize). I'll search for a link if I can to among the bug records (I bear in mind seeing it reported greater than as soon as).

In my experience, it often tends to take place under the problem that the system is warm, so I'm not exactly sure if that relates. It additionally takes place usually the very first time I suspend after a bit upgrade, after that discontinues to take place once more till either :

  1. The system is piping warm.
  2. I've done a kernel/driver upgrade.

My pointer, do not suspend if it is actually warm, instead permit it to cool down first (maintaining a high strength application working on suspend is a negative suggestion, also on home windows, and also usually is the source of the warmth trouble), and also reactivate two times after a bit upgrade (in some way that solutions it for me, not exactly sure why).
