When you resume Windows XP from hibernation, it occasionally stops responding on a black screen.
This behavior may occur when you have at least 1 GB of RAM.
To workaround this behavior:
1. Shutdown the computer.
2. After 1 minute, restart Windows XP.
3. If you receive The system cannot resume from hibernation. Do you want to restart again? select Restart the system again.
4. If you receive the same error again, select Delete restoration data and proceed to system boot menu.
