Yesterday I discussed how laptop computers are designed. One important point I should mention is that laptops are not designed for user serviceability. The screws are small, the parts are tightly fitted, and one wrong move might ruin or destroy the unit. There’s enough energy in a laptop battery to start a fire, as I discussed in my posts from 15 August 2006 and 1 October 2006.
Most laptops have small doors that users can open to replace and upgrade RAM and hard disk drives. Almost every other kind of repair or upgrade should be performed by a professional who has the tools and experience for the job.
If you really want to look at some computer hardware, check my PowerPoint file in this 17 February 2008 post.
Warning!
Never attempt to open or service a laptop computer while the battery is installed, or while the computer is plugged in to AC power. Disconnect the power sources, but be careful, because the computer’s parts are still charged with a hazardous amount of electricity. To remove this charge, press the computer’s power switch for at least 10 seconds. This will discharge the capacitors inside the computer.
