Notebooks, Tablet PCs, and PDAs
              Tips for Buying a Notebook
• Consider a notebook if portability is important
    – Desktops are faster, cheaper, and easier to upgrade
• Do not buy extra features unless they are needed
    – Extra features are costly and add to notebook weight
• Purchase an extended warranty
• Select a well regarded brand
• Some guidelines for notebook components:
    – Choose an active matrix LCD panel (over dual scan)
    – Buy as much memory as you plan to use later
    – The best type of battery to buy is a lithium battery

           Special Considerations When
              Servicing Notebooks
• Diagnostic tools provided by manufacturers
    – Used to pinpoint a problem component
    – Sources: setup CD or manufacturer’s Web site
    – Example: PC-Doctor
• The OEM operating system build
    –   Notebooks are sold with the OS preinstalled
    –   OEM: original equipment manufacturer
    –   OS build: customized operating system build
    –   Diagnostic software is customized to the notebook

• Alternatives to fixing (or upgrading) it yourself:
     – Return notebook to the OEM or other service center
     – Substitute an external component for internal device
• Guidelines to follow if you choose to replace device:
     – Obtain instructions for replacing an internal device
     – Back up important data and take safety precautions

               Replacing the LCD Panel

• Diagnosing a problem when panel is dim or black:
     – Connect an external monitor to the video port
     – If external monitor works, LCD panel is likely broken
• Causes of a malfunctioning LCD panel
     – Video inverter card is not working (relatively minor)
     – Faulty LCD panel assembly (major)
• A few tips for successful a disassembly

   –   Writing: laser beam writes -100 V image to drum surface
   –   Developing: toner is applied to -100 V areas of the drum
   –   Transferring: toner drawn off drum and onto the paper
   –   Fusing: heat and pressure used to fuser toner to paper
