When the computer goes into the sleep, hibernate, or hybrid sleep state, there is no indication on the display for users to notify that the computer is still in transition to the sleep, hibernate, or hybrid sleep state. Once the computer begins to go into one of these states, the display will black out at once. With this behavior, mobile users may think the computer has finished the state change and may carry and move the computer while the hard drive is still running. This may cause damage to the hard drive.
Sleep and Hibernate
- It is common for all ThinkPad 3000 Famiy notebook systems running Microsoft Windows Vista.
To avoid causing damage to the hard drive, mobile users should wait until the hard drive LED turns off and the sleep LED turn on when the computer goes into the sleep or hybrid sleep mode. You should wait for hard drive LED and sleep LED to turn off when the computer goes into the hibernate state.

After your computer resumes (or "wakes up") from hibernation, it enters hibernation again after two minutes of inactivity, regardless of the settings you have configured in the Power Options of the Control Panel.
Any notebook system running Windows Vista.
After resuming from hibernation, if you can make some operation, for example, moving the trackpoint or typing on the keyboard or running an application and so on, then the system will not go back into hibernation state.
