Because of the large power saving, most laptops automatically enter ...
Advanced Configuration and Power Interface (ACPI) is an open standard that operating systems can use to discover and configure computer hardware components, to perform power management (e.g. putting unused hardware components to sleep), auto configuration (e.g. Plug and Play and hot swapping), and status monitoring.
Needing more sleep during the winter may also be due to what’s known as “social jet lag,” experts said, meaning that the fun, late nights you had all summer may be why you’re having ...
