Linux 4.8 May Fix An Issue Of Some Laptops Burning Through Power While Suspended

It looks like some newer Intel laptops will be much happier when S3 suspended with the upcoming Linux 4.8 kernel.

For at least some newer Intel laptops with distributions like Ubuntu 16.04 LTS and Fedora was a case where suspending the system would still still be consuming much power: a hot laptop and losing around 12% of the battery life per hour while "suspended."

It appears that with the Linux 4.8 kernel this issue has been addressed, but it's not clear if it was directly addressed. A Phoronix reader who experienced this problem pointed out this bug report and reported his laptop's power problem was indeed addressed by Linux 4.8.

I'll be running some usual Linux kernel power consumption tests on various systems in the next few weeks to see if there are any other surprises as hopefully some icing on the cake to Linux 4.8's other exciting features.
