CHAPTER 5: Managing Power

60

Changing power modes

You can use the following power modes to lengthen 

the life of your notebook’s battery:

•

Sleep

 - while your notebook is in Sleep mode, it 

switches to a low power state where devices, 

such as the display and drives, turn off.

•

Hibernate

 - (also called 

save to disk

) writes all 

current memory (RAM) information to the hard 

drive, then turns your notebook completely off. 

The next time you turn on your notebook, it 

reads the memory information from the hard 

drive and opens the programs and documents 

that were open when you activated Hibernate 

mode.

•

Hybrid Sleep

 - while your notebook is in Hybrid 

Sleep mode, it switches to a low power state 

where devices, such as the display and drives, 

turn off similar to Sleep mode. The notebook also 

writes all current memory (RAM) information to 

the hard drive similar to Hibernate mode. If your 

notebook experiences a power outage while in 

Hybrid Sleep mode, the notebook reads the 

memory information from the hard drive and 

opens the programs and documents that were 

open when you activated Hybrid Sleep mode. If 

the notebook does not experience a power 

outage while in Hybrid Sleep mode, it restarts 

using the information in current memory, thus 

reducing startup time. You must turn on Hybrid 

Sleep mode to use it. For more information, see 

.

Using power saving modes

Always save your work before using Sleep mode. In 

Sleep mode, your notebook reduces or turns off the 

power to most devices except memory. However, the 

information in memory is not saved to the hard drive. 

If power is interrupted, the information is lost.
