Christo Design Further Diagnostic Questions and Some Fix Suggestions 1.   If the CD/DVD Drive Door Will Not Open: • See if the tray is obstructed. Stick a straightened out paper clip in the little hole and try to push out the tray. • With removable laptop drive, pull it out and shove it back in solidly. • With removable laptop drive, also clean the contacts of the drive with a pencil eraser. • With a PC, unplug the machine and pull the data and power cables and then reseat them firmly, being sure to connect completely. • With a volt meter, test the power cable going to the drive. It should have two wires with a 5 volt ~1 amp circuit and the other two with a 12 volt ~1 amp circuit. • From these tests, you can determine if the drive is mechanically and electrically sound and if the power supply needs replacement. • Note that there are usually several spare power supply drive leads which can be tested and used to replace a faulty one. • Purchase and use a "CD Lens Cleaner" or use a compressed air cleaner can to clean out the drive.
