[QUOTE="thehumble1, post: 479420, member: 32765"] [b]In over your head probably, but keep trying.[/b] The small chip is the reed switch. It's job is to put your computer to sleep. This may or may not have anything to do with your symptoms, but you were correct in thinking that you needed to transfer this over. There is a chance that the switch was damaged in the process or somehow giving the computer a bad signal. You can test this by moving any magnet close to this chip. When you do so it will put your computer to sleep. It sounds though like your problem is that the computer is going to sleep a lot so maybe something for the narcolepsy is more important. The background may be helpful down the line, but the basic symptoms are: 1) with Original Optical drive, CD not booting 2) backlight working intermittently after new optical drive installed, after boot 3) boot taking more time with new optical drive 4) With the boot time going way up, I'm pretty sure you are having a hardware conflict with the new drive. Someone can correct me if i'm off base, but when the load time increases after a change of hardware, it probably means the computer is working to locate the hardware, figure out what it is and load drivers for it and probably failing every time. Since a lot of Mac hardware is proprietary, it's not set up for swapping with near-exact stuff (at least in my experience). I'd put the original Optical Drive back in and see if the other problems go away. If you don't have a know good exact replacement and you are having problems, I'd remove it from the equation for right now. If you do have access to another Mac, try looking at this page ([url]http://lowendmac.com/misc/06/0710.html[/url]) which is talking about installing OS X through firewire instead of DVD. Which begs the question: are you installing from DVD when the optical drive is only capable of reading CDs? Newer versions of OS X are on DVDs not CDs. That would spit things out quickly. Just checking. Your description is fairly confusing, but it sounds like everything was working fine on the computer before you started, right? But that you wanted to reformat (and reinstall OS X presumably) the drive to get it ready to sell. So at baseline there were no problems right? Could it read other CDs? Did the rest of the system function properly? You mentioned that "the laptop" reads the install disk but doesn't load it, which laptop were you talking about (sick one, or your friends) and when does it read it (while running OS or in hardware check on boot or at command prompt?). I'd put the original optical drive back in, fire it back up and see if you can get back to where you started, which would mean no damage done. Then I would research these optical drives and see if they are an exact match. If they are, you might have 2 bad drives on your hands and you could still sell it with a broken drive for a good price. But some specifics on what happens when in a more itemized or outlined style would help a lot. I hope this works out for you.
