Don't remove the ribbons, just move the keyboard slightly forward to remove the old battery and insert the new one (just make sure they are all connected when you put it back)

Now that the ribbons have been detached from the bottom cover, carefully remove the keyboard plate cover. Once it has been removed, place it in a safe and moisture free area so it does not get damaged.

Now, that is a stupid question! Of course! As I am working on 551M, I naturally have to have nails painted orange, with blue accents!

this spacer may be a cd rom drive or potentially a second storage device like an ssd or hard drive. Either way the process is the same, remove the single screw, and slide to the right.

Remove the wires by easily pulling them parallel to the motherboard's surface. The wires are very fragile. Be sure to pull carefully so that they do not break!
