Without being able to access the bios, on a server running CentOS 6.4, is there any way to disable the C6 and C7 power saving states from the kernel?On my install this does not exist:
So I noticed when I went to go use one of my apps that uses GPS the other day it said the phone had to come out of power saving mode to turn on the GPS, so I did that. Now I can't seem to find where to enable and disable Power Saving. I am not talking about the Extreme Power Saving feature that we don't have yet, just the normal power saving feature.
In the wiki at https://wiki.archlinux.org/index.php/Po … interfaces it is explained how to enable power saving for all wifi devices using a udev rule.That should also work the other way round to disable power saving, just replace "on" with "off".
As I have mentioned the school MinecraftEDU server before, now I need to disable the power button. The computer is in a place where many kids are a lot, so we need the power button disabled so nobody can turn off the computer.
