Standby and Hibernate were two functions in pre-Vista operating systems that would save the current PC state either into computer memory or on the hard drive before shutting down most of the computer to save energy. Microsoft has changed those states in Windows Vista and kept them this way in Windows 7.
The new power saving modes sleep and hybrid sleep replaced standby and hibernate. Sleep is just another name for standby. The data is saved to computer memory in this state before most PC components are turned off. Hybrid Sleep is a mix of sleep and hibernate as it saves the work both into memory and on the hard drive. The latter is turned off by default on mobile devices.
The reason for hybrid sleep being turned off on mobile devices is that they will automatically switch into hibernation if they run low on battery.
Some Windows users have problems with the Hybrid Sleep mode as it uses settings that can put a PC into the mode even if it is not idle.
Dont Sleep is a portable software program for the Windows operating system that can block the OS from going into sleep and hybrid-sleep mode. The program will display a list of options upon startup, namely to block:
- Standby, Hybrid-standby and Hibernation
- Shutdown
- Logoff
- Screensaver and turning off the monitor
The user can place the icon in the system tray from where it will do its magic. It is further possible to set a timer to turn the program off at a specific date and time so that the modes are not longer blocked.
Don’t Sleep is a portable software compatible with 32-bit and 64-bit editions of the Windows operating system.
