简介
The click wheel receives the feedback of your fingers and transmits it to the logic board.
你所需要的
-
-
Remove the following 3 screws:
-
Two 3 mm Phillips screws near the dock connector.
-
One 4 mm Phillips screw along the edge of the logic board.
Note that the 4mm screw has slightly wider pitch; you'll need this when putting the unit back together.

Insert the flat end of a spudger between the battery and the headphone jack side of the front case to pry the battery up off the adhesive securing it to the front case.
-
Rotate the battery out of the iPod and lay it next to the iPod. The battery is still soldered to the logic board by three wires, so don't remove it entirely.
-
-
-
Grasp the end of the logic board near the battery connector with one hand, and hold onto the rest of the iPod with your other hand.
-
Slide the logic board out of its holding brackets on the rear of the display.
During the disassembly of the board I somehow "delaminated" the display. The result was that the display (after the battery was changed and the device closed again) looked "cloudy". From some angle you couldn't see anything at all anymore. The solution was to heat up the hole device with a hair dryer and rest it on it's front side for about an hour. After that it looked absolutely perfect again. I am not sure whether the heating is really necessary (maybe just lying the ipod on the front side over night would have the same effect) and surely one should be careful to not overheat the device.

Use a spudger to flip up the black plastic tab holding the orange display ribbon in place. The black tab will rotate up 90 degrees, releasing the ribbon cable.
Both ribbon cables were especially difficult to put back in. I can't say I succeeded in getting the nano to work again. If you can avoid detaching the cables, do it. If you're replacing the clickwheel, there's no way of avoiding it unfortunately.
A little tip if you are replacing the screen: Reconnect this ribbon cable from the new screen BEFORE affixing the screen to the adhesive! It will make it much easier. Also be sure that the little black things are UP before trying to put the ribbon in, and make sure you put them DOWN before closing up! The black things on the receptacle "lock" the cable in place, so it is important that you have it STRAIGHT or it wont work. Good luck!

Use a spudger to slide the display ribbon out of its connector.
Getting the display ribbon back in place is the most difficult maneuver in the whole fix. I actually broke the black plastic tab in half while trying to close it back down, (be very gentle with it!). Managed to put the broken half back in(tweezers and patience) and get that ribbon in and put it back down. This battery replacement was the most difficult/tedious repair I have ever done. Don't do it unless you are brave and stubborn.
You can leave out this steps with disconnecting the two cables.
Without disconnecting the two cables, one can separate the two pieces only 1/2 inch. This is enough to work carefully with the soldering iron and change the battery.
It's a little bit difficult to work with the needle to open the three holes after removing the old battery - but you can do it.
From the reading of the other notes it seems to me easier than to disconnect the two cables

Don't do this unless you have to. Getting this ribbon back in is nearly impossible.

Try using tweezers or medical clamps to reach in that tight spot. Use these tools to also connect the click wheel ribbon back to the logic board.
Stamp tweezers worked great for the ribbon cable! (Search eBay or Amazon, or your local hobby store.) This would be a useful tool for iFixIt to add to their inventory.

Use a spudger to carefully pry up the adhesive holding down the edge of the display.
Be careful when you are trying to remove a working display from the nano it came on (when replacing the faceplate as well). Because of the adhesive, too much force or pressure can cause the display to crack and cause the display to "bleed"... resulting in replacing that part if it was still good. Try using a hairdryer to gently warm the adhesive to then remove the display. Warning: Too much heat can also ruin the display or melt the front panel.
Also watch out as the display is in two parts that can separate.
I replace 2 displays, and they are still white,nothing else...maybe I damage

Lift up on the click wheel cover and carefully thread the orange click wheel ribbon through the slot in the click wheel cover.
-
Lift the click wheel cover out of the iPod.
The click wheel cover is secured with extremely strong adhesive, so "lifting the click wheel cover" out of the iPod will only come after prying it up with a razor blade or something equally thin.
Ma è saldato? Non riesco ad estrarlo

Lift the click wheel out of the front panel.
I've opened up a number of macs but the Nano was far tougher. Make sure you have tweezers and great light.
