My Satellite a105 is not that bad of a machine.
However, it does have its drawbacks.
Dust is everywhere inside and out.
Touchpad is uneven surface, probably food.
Keys (albeit very unused) are missing and wobbly.
DVD drive reads all CDRs as blank disks.
(taken care of, but wanting to help prevent) Dust in HSF area PEELS OFF OF THE HEATSINK, like you do with a lintscreen.
Fingerprints galore on screen.
(and WAY too glossy of a finish; black the screen, it nearly makes a perfect mirror.
Annoying dust IN MIDDLE, NOT EASILY REMOVED, OF SCREEN!
What is the best action for each of these steps?
