Hardware, Utilities and Options

If your computer is configured with more than 3 GB memory, the memory might be displayed as approximately 3 GB only (depending on the computer’s hardware specifications).

This is correct because the operating system usually displays the available memory instead of the physical memory (RAM) built into the computer.

Various system components (like the video adapter’s GPU and PCI devices like Wireless LAN, etc.) require their own memory space. Since a 32-bit operating system cannot address more than 4 GB of memory, these system resources overlap the physical memory. It is a technical limitation that the overlapped memory is not available to the operating system. Even though some tools might display the actual physical memory built into your computer, the memory available to the operating system will still be approximately 3 GB only.

AC adaptor	The AC adaptor provides power to the system
	and recharges the batteries when they are low. It
	comes with a detachable power cord which will
	either have a 2-pin or 3-pin plug enclosure.
	As the AC adaptor is universal, it can receive a
	range of AC voltages from 90 to 264 volts,
	however you should note that the output current
	varies among different models. Using the wrong
	adaptor can damage your computer. Refer to the
	AC adaptor section in Chapter 2, The Grand
	Tour.
