WiFi routers and modems
With rising electricity prices, more and more people are paying attention to where unnecessary electricity consumption and the associated additional costs can be saved. Some devices are worth unplugging when not in use as they use more power in standby mode than they should. However, one should note that not all devices should be disconnected from the network, as t3n explains. For example, WLAN routers and modems should not be completely disconnected from the power supply, as this means that many things such as the house telephone, smartphones and tablets can no longer be used without restrictions. In addition, if these devices are switched on and off frequently, providers may assume that there is a fault in the router due to the lack of feedback. However, if you are not at home for a long time, such as on vacation, you can and should switch off the router to save electricity, explains EFAHRER.com.
PCs and notebooks
According to t3n, it is also less advisable to unplug PCs and notebooks from power outlets that can be switched off. This could have two negative effects on the devices: On the one hand, the BIOS battery as a power reserve always ensures that the basic settings, such as the boot sequence and built-in hardware, are retained. If the computer is only switched on for a few hours a week when it is used, the battery will have to be replaced in the long term. While this is still relatively easy for experienced users to do themselves with a computer tower, going to a workshop or dealer is necessary for ultrabooks at the latest. As t3n reports, there is another reason for Windows 11 users not to disconnect the notebook from the power supply, namely the battery management, which ensures that the notebook battery is always serviced.
OLED TV
OLED televisions should also not be unplugged. These regenerate the individual self-illuminating pixels with each start, so t3n. If you now regularly disconnect them from the power supply, this can lead to a deterioration in the image quality in the long term. In addition, many televisions download updates during the night when they are in standby mode.
printers and multifunction devices
According to t3n, you should also refrain from regularly unplugging printers and multifunction devices such as printer-scanner-fax combinations. The reason for this is the self-cleaning and the self-test, which are carried out with every new start and which lead to unnecessary ink or toner consumption.
