The different power managements fro a laptop and a Desktop.

Laptop- Are portable so that means they have a batteries to power them which are usually chargeable.

To configure power settings you need to:

2. Locate and enter the Power Management settings menu item.
3. Use the appropriate keys to enable ACPI mode.
4. Save and exit BIOS setup.

There are differences between power management  on Laptop and Desktops. Laptops have batteries while desktops have to be plugged intno power. The advanced  figuration and Power Interface (ACPI) standards create a bridge between the hardware and OS for people to get the best power management for there computer or l.

The difference between laptop and desktop components are that you can take out and fix laptops easier than desktops. Also they are easier to take to places if you wanted it to repair. Although you cannot take laptop components and put them into a desktop as they are different sizes. Plus laptops are wirless and are portable unlike desktops which have to be pluged into with and internt cable. XD
