I have a Toshiba Satellite C855D-S5307. The computer came with Windows 8 and all the power functions seem to work fine with Windows. Whenever I install Ubuntu 13.10 (or any equivalent ie. Linux Mint, Xubuntu, Lubuntu, Kubuntu) it does not stay asleep. It suspends for about 1 minute, then the fans start running like crazy and it gets very hot. This continues until the battery is completely drained. I can't imagine it's good for my hardware either.

I have triple checked the power settings and even tried re-installations. I'm not an expert Ubuntu user, but I have used it before. This is the first time I'm having power issues on a laptop (This laptop is relatively new and I have not tried to run it before).

I've tried changing the suspend/hibernate in Ubuntu and in the Tweak Tool with no luck. Has anyone else had this problem? Any help/fix would be greatly appreciated.

I figured it out. Not sure why it made a difference, but I installed 12.04 LTS and tried this fix. Seems to have worked. 12.10 and up didn't seem to work with that bit of code. But whatever, I'm happy. it's working now.
