Notebooks

1. A portable computer (Laptop or notebook) uses similar technologies with that of desktop PC, with important adaptations.

   • Some specificities are added on the new models like reader DVD and TV output.

2. General presentation of hardware of notebook.

   • A motherboard (23) including the inputs/outputs: graphic card, wearing of communication series and parallel, chipset, controller E-IDE and diskette.
     • A processor (24) often directly welded onto the mother chart (no-replace).
       • The microprocessor can be of type mobile or standard.
         • The standard processors are used in the office automation PC and not optimized for a reduced consumption.
         • The processor mobiles use advanced techniques to reduce their speed in the event of nonuse, even of short period.
   • Memory: Just like the microprocessors, a portable the bottom-of-the-range one uses standard office automation memories.
     • A monitor (1) of flat type.
     • A monitor (1) of flat type. . A battery. It allows an endurance until 3 hours, much less if the processors and memories are standard.
     • . A power supply also being used as battery charger.
   • The external connectors are identical to the ports of the office computers with some characteristics. To reduce space, the number is often reduced.
     • Generally, a port screen makes it possible to be connected on an external screen.

3. Mobile processors

   • Portable specific mobile microprocessors
     • INTEL was a long time the only manufacturer of this type of processor
       • AMD produces also processors with low fuel consumption of energy, provided with systems of economy
         • The CRUSOE, specific for portables, having disappeared from the market
           • Portable processor is not different from that of a standard microprocessor, only of the mechanisms of energy saving are added. These processors are generally followed letter M for mobile

4. INTEL

   • INTEL installed in its series M 2 functions ofLEEP and the function speedstep. energy saving (as well CELERON as Pentium IV): function DEEPER
