Power-Up in Standby (PUIS) mode allows devices to start up in standby mode, saving energy by only activating when needed. Quick start functions can be added for easy use, and inactive components return to standby mode to conserve energy. Not all systems support PUIS, but it can reduce energy consumption and extend the life of devices. Consumers can look for products with this feature or ask sales representatives for assistance.
Power-Up in Standby(PUIS) is a mode available on some electronic devices that allows them to start up in standby mode, rather than active. When the user actually needs access to the device, a signal tells him to switch to active mode. This saves energy by ensuring that the equipment is only fully active when it is needed and remains on standby when it is not. Some computer systems have components programmed automatically with a power-on-standby setting, and it may also be possible to adjust equipment and accessories to enable this feature.
Historically, when power was supplied to a device such as a hard drive, it immediately booted up and went into active mode. This created a power drain, although it also made the content instantly accessible to the user. With power on standby, when you power on, the hard drive or other device recognizes it and starts up in standby mode. Uses less energy, waiting for a command from the user.
To facilitate ease of use, a quick start function can be incorporated into the equipment so that the user receives an almost instantaneous response when signaling the equipment to wake it up. It switches from standa mode to active mode, starts up and prepares for use. The system can be programmed to return the device to standby when it has not been used for a specified period of time, allowing inactive components to conserve energy by returning to a mode that uses less energy. When the user needs to access the equipment again, it restarts in active mode.
Not all systems support power-on-standby, which can be an important consideration when ordering a custom system or modifying an existing one. Manufacturers that produce devices that can support this feature may have documentation to help users determine what specifications their systems need to support them. You may also need to go into system programming to adjust the settings to turn the ignition on in standby mode to turn it off if you don’t want to.
This is one of the options provided by computer manufacturers to reduce energy consumption. As well as being kinder to the environment, this can help systems last longer by reducing heat and not overworking the cooling system. Consumers who want a power-on-in-stand option on new computers and accessories can look for products that specifically advertise this feature or ask sales representatives for assistance.
