The computer provides the following two types of suspend modes for you to save power: Suspend mode. In suspend mode, all tasks are stopped and stored in memory to save power. When the computer resumes normal operation, the tasks are automatically restored. RediSafe suspend mode. Create a hibernation file before using this mode. In RediSafe suspend mode, all tasks are stopped, and the memory data and the status of the computer are stored on the hard disk drive. This prevents accidental loss of the data during suspend mode. Resuming normal operation is faster from RediSafe suspend mode than it is from Hibernation mode; the computer resumes normal operation when you press the Fn key in RediSafe suspend mode. If all battery power is used and the computer turns off during RediSafe suspend mode, install a fully charged battery pack or connect the AC Adapter; then press the power switch to resume operation. All tasks are restored. Chapter 4. Using Battery Power 65
