My laptop's battery always run out after 3-4 hours. Since my class is more than 4 hours per day, the battery duration is not sufficient for me. Whenever I didn't use my laptop, I will change it to sleep(stand by) mode. It still consume small amount of energy. I try to use hibernate.(Sleep vs Hibernate)However, hibernate option is not available in my Window Vista. I have found a solution for this problem.
Why Option Is Not Available?
- The Disk Cleanup Utility and has been used to delete the Hibernation File Cleaner.
- The computer does not support the hibernation feature.
- The hibernation feature is disabled.
- The Hybrid Sleep feature is enabled.
How to Enable?
1.Click Start button, type command in the Start Search box, right-click Command Prompt in the Programs list, and then click Run as administrator.
*Note:User Account Control permission If you are prompted for an administrator password or confirmation, type your password, or click Continue.
2.At the command prompt, type powercfg /a.
The PowerCfg tool generates output that resembles the following:
The following sleep states are available on this system: Standby ( S1 S3 ) Hibernate Hybrid Sleep
The following sleep states are not available on this system: Standby (S2)
The system firmware does not support this standby state.
3.Done!
You should able to get a hibernate option in the menu.

i wish my notebook has 3-4hrs battery life...i own a sony vgn-c25g n i searched the net all vgn-c25g users mention that their battery life can last for at least 2-3hrs but for mine only 1-2hrs for normal use...i was thinking whether i got cheated by the seller which give me a used battery...damnit
chicken>> Are you using the power saver mode? If you are using high performance, your battery will run out very fast. To reduce the power consumption, you can reduce the brightness(acceptable range)
i personel feel that winxp hibernate are more faster then win vista. At vista, using shutdown is more faster if there are no program remain opening.
