DADDY BOB'S COMPUTER Q & A

Q. Do I need to keep the hibernate feature active in my desktop if I never use it? If not, can I reclaim the uses hard drive space?

A. I covered this in an article back in December 2006, but since there have been two operating system updates since then and some procedures have changed, I'll do it again.

A note here: If you have 4 or more GB of usable RAM in your computer, there is no hibernation feature available. This will only occur if you are running a 64 bit version of Windows since the 32 bit version will never be able to use a full 4 GB of RAM even if that much is installed. To learn why this is, click HERE.

There are several ways to disable hibernation, and disabling it will automatically delete the "hiberfil.sys" file. This file is by default, the same size as the total usable RAM in your computer so this recovered space could be as large as 3.5 GB.

Here are several ways to disable hibernation. They all may not work in all versions, but at least one will work in all versions. Since Windows 7 is the current version, these all apply to it.

Enable or Disable Hibernate Through Command Prompt
Using the Command Prompt might be the easiest way to enable or disable Hibernation. Click on Start and type CMD into the search box and it will be listed under programs. Right-click on the icon and select Run as administrator. When the command prompt opens, enter powercfg /hibernate off and press Enter. To turn it back on, follow the same procedure but enter powercfg /hibernate on.

If you try this option to turn hibernation mode on but it still isn't available Then you’ll probably have to disable Hybrid Sleep by expanding Allow hybrid sleep and turning it Off. Then you should have Hibernate and Sleep as part of the power options in the start menu and will also be an option when you hit Ctrl+Alt+Del.

Manage Hibernation Through Control Panel
Click on the Start Orb and open Control Panel then click on Power Options. On the left side click on Change when the computer sleeps. Now click on Change advanced power settings.

In the Advanced Power Options window expand the Sleep tree then expand Hibernate after and change the minutes to zero to turn it off. You can also change the way the computer hibernates here if you so desire. Click OK to close the dialogs.

Disable Hibernate By Modifying The Registry:
To completely disable hibernation, you can modify the registry. This is not recommended for tose that are not totally comfortable with modifying the registry. To do this, click on the Start Orb, select Run and enter regedit. Now browse to HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Control\Power and change both HiberFileSizePercent and HibernateEnabled value data to zero. After you’ve made the changes close out of the Registry Editor and restart the machine.

If you always turn off your computer or never turn it off, you can disable the Hibernate mode to gain a bit of extra hard disk space. In this time when hard drives sizes are so large, this 3+ GB of restored space may seem insignificant, but if you can reclaim it, why not do it?
