The “sleep” or “hibernate” functions that run by default in Windows 7 can prove to be problematic. I advise my clients to restrict hibernate/sleep functions for usage only in absolutely needed circumstances. It is commonly problematic and seldom ever fixed. Myriads of causes you can spend weeks trying to find. Just not worth it.
FIRST: If you are running a desktop PC, shut down all sleep and hibernate functions. They are of no value and will cause you problems eventually. But, for some notebook PCs, where the computer is used in a truly mobile sense, where house power is not always available, you need these functions to extend battery life.
Background: The concept of sleep/hibernate was designed to extend battery life. If you are not running on a battery or never do, the very idea is quite useless. If you are doing it because your computer takes a long time to startup, fix that problem. Under normal circumstances if you are finished using the computer and do not plan to use it again for at least several hours, shut it down. Leaving it running continuously is a sure way to shorten your computer’s life
You can change how these functions behave here:
- Start globe
- Type Power options in the text box that pops up
- Desktop computers:
- Set all hibernate/sleep functions to NEVER
- Notebook computers:
- Again, set all hibernate/sleep functions to NEVER, EXCEPT when it is battery powered.
- In the Power Options window, Click Change Power Settings
- Change Advanced Power Settings
- Set hard disk to turn off after 20 minutes of non-use
- Under Sleep, several settings:
- Sleep After NEVER
- Hybrid after: Never
