Disable Hibernation
March 9th, 2009 Posted in Server 2008If you’re in need of disabling hibernation on your 2008 servers (or your Vista desktop, as the case may be), open a command line and type this:
powercfg.exe /hibernate off
To turn it back on, replace “off” with “on”.
This will do away with that annoying file (hiberfil.sys) at the root of C:\ (or whatever your system volume’s drive letter may be) that is the size of your physical RAM – thus freeing up much space.
Keep in mind, however, that hybernation cannot be turned on if you have Hyper-V installed. I’m curious, though, why would you hybernate a server? And before those of you that use 2008 as a workstation complain, why would hybernation be enabled by default?
