Using the power button (on/off) for the purpose of various fixes
The on-off button (switch) present on all laptops/PCs/servers can be used for purposes other than power on/power off/sleep/hibernate/closing the screen (or other options made available through the operating system or integrated firmware). In general, the applicability of the following method also extends to other devices that employ ram memory (and capacitors), such as smartphones or printers.
Situations that can be fixed include, but are not limited to the following examples:
-non-functional laptop keyboard
-laptop keyboard that responds incorrectly or clumsily to pressed keys
-occasionally helps with BSOD fixes
-allows the detection of devices/peripherals/components that would otherwise not be recognized (including certain SSDs, in which case it is recommended to save the data on them and replace them with a model that does not show this symptom).
