MORE INFORMATION

When you enable Hyper-V technology on a Windows Server 2008-based portable computer, you lose the sleep power feature and the hibernate power feature. These power features are available before you enable Hyper-V on a Windows Server 2008-based portable computer. Additionally, you cannot re-enable these power features.

Because the sleep and hibernate power features are not available, these features are not enabled when you close the lid of a portable computer. Then, when the battery of a portable computer runs out of power, the portable computer may shut down or turn off, and the portable computer does not go into hibernation. Because the portable computer does not go into hibernation, you may lose any unsaved data.

Note Hibernation saves a desktop session.
