Well, in case I don't get on A2K for a while I will give a possible solution to the sleep/hibernate problem.
This solution assumes that the ability to set your computer to hibernate was turned off and gives instructions on turning it back on.
- Right click your desktop
- Click on "Properties"
- Go to the "Screensaver" tab
- Click the "Power" button to change the power settings.
- In the power settings choose the "Hibernate" tab.
- Verify that you have enough space on your computer to hibernate*.
- Make sure the box "Enable hibernation" is checked.
- Click " Apply" then "Ok" you way out.
*Your computer needs space on the harddrive to hibernate as it will write temporary files to store your hibernation information to the hard drive.
It does this to preserve the information in your RAM etc at the time, so that when you turn it back on it is restored as it was when it started to hibernate.
To verify that you have enough space to hibernate you can look at the box on the hibernate tab. It will tell you both how much free space you have and how much is needed to hibernate.
If you do not have enough space to hibernate you have a problem. It means your disk is very very full (as hibernation usually only takes about as much space as the RAM you have on the box).
Letting your hard drive get almost completely full is dangerous. Your harddrive needs empty space to perform maintenance tasks. For example defragmentation is a process in which your files are moved to a blank portion of the disk while it's being reorganized.
Your RAM settings might include use of disk spac as memory as well.
So if you are that low on space you need to rectify it. You should always keep some free space on your disk.
