I'd also recommend some kind of anti-static device, be it an anti static wrist strap or something you can gound the components to. You don't want to do a great job on the screen only to find that you've messed up the memory with a static shock. A typical static shock you can feel is about 2,000 volts. It only takes 200 volts to destroy your CPU, so you won't even know you've done it. I usually touch the pipes under my sink before working on the computers.
Some computers also allow you to turn them off and still be grounded through your house's earth, and you can just touch the metal case, but this probably won't work on a laptop.
I have always believed in the old saying - Teenagers are God's way of making it easier for mothers when they leave home.
As a father of course I grew a bit tired of the horrible, noisy, smelly, ungrateful creatures when they were about 10 but my plea to the wife to stop feeding them because it only made them stronger fell on deaf ears!
Mine are now well into their 20s and still living at home - bugger!
Of course I blame Gordon Brown for making it too expensive for them to buy a place of their own but that's a different story ... and not really much to do with computers - except they spend half their life playing games on the damned things!
