This old workhorse lasted 5 years before needing a new CD. Glad i found these instructions.
I had a bit of trouble following the jumble of instructions on this, so i have melded them into one, to clarify the disassembly procedures for the Gateway 200ARC :
Remove all screws on the bottom of the unit, including the one under the HD cover.
Turn-over the unit, and remove the keyboard. Lift the keyboard near the rear of the machine, and tilt it forward. To remove the keyboard’s ribbon-connector at the motherboard: the ribbon-clasp on the motherboard slides forward (toward the front of unit), then tilts up to release the ribbon. When the keyboard is out, remove the two ribbon-connectors found near the center of the exposed motherboard. The one near the rear is to the power and controls at the rear of the unit. The one toward the front is to the mouse.
To remove the LCD screen: Each hinge of the LCD has a small cover on the top (same surface as the power button). There is a pry-hole to the inside-side. Pry the cover at that point, then pry around the front until the two catches release. Lift the covers (with some pressure) untill the screw can be accessed and removed. The cover on the right hides two wires, which unclip, and lift out. The cover on the left hides a ribbon-connector. Lift (unplug) the connector, and lift out. Lift the LCD up and away from the unit, and lay aside.
Unclip the top-cover (surrounding the keyboard) from the unit, by using a pair of small flat-blade screwdrivers to separate the cover from the front, right-side, and back. The cover needs to be pushed slightly to the left, to un-clip it from the left-side panel.
Lift and remove the cover.
Unclip the CD’s ribbon connector. The CD has two screws, to the left, holding the CD’s two metal tabs. Remove these screws, and move the CD about 1/4 inch to the right, where it can be lifted out.
