How to replace the hard drive - HDD – Apple iPod Classic

Apple iPod Classic: DISASSEMBLING PROCEDURE 

Apple designed their iPods to be very difficult to take apart without destroying major components. Because of the metal face plate, the metal backing, and the 13 metal clips holding the case together, this is one of the toughest Pods to disassemble. Proceed with caution and the warning that you may significantly damage your iPod beyond its present condition. Also, you may want a few extra pairs of plastic
opening tools during installation, as they are easy to ruin when opening the iPod. Have fun! Before opening your iPod, ensure that the hold switch is in the locked position.

Opening this iPod is challenging. Don't get discouraged if it takes you a few tries before the iPod is opened. One thing to notice is the angle of the plastic opening tool's tip while inserting it into the iPod. Ideally, the angle should be as vertical as possible while still clearing the edge of the rear panel. Insert a plastic opening tool into the seam between the front and back of the iPod.

Insert another plastic opening tool into the seam between the front and back of the iPod, leaving at least 1.5 inches of space between the two tools.

At an angle, carefully insert a putty knife about 1/8 inch into the seam between the two opening tools. There are thin metal rails running along the inside of the rear panel, so take great care when inserting the putty knife.

Once the putty knife has cleared the lip of the rear panel, pivot the putty knife so that it is vertical, and carefully (but firmly) wiggle it straight down into the gap between the opening tools.

Push with your fingers on the rear panel behind the putty knife to minimize bending. Slowly flex the putty knife, as shown in the picture, to ensure that most of the metal tabs on this side of the iPod are disengaged. The theory behind this method is, rather than attempting to not bend the rear panel at all, to bend it in a favorable manner that allows you to easily restore it later. Therefore, any bend in the sides of the rear panel should be drawing the lip of the rear panel away from the iPod, rather than pushing out on the curved surface. This method also disengages as many of the side clips as possible.

Remove the putty knife from the iPod and reinsert it closer to the corner of the iPod, using the same wiggle method as before.

If at all possible, do not bend the corner of the rear panel.

Between the lock slider and headphone jack, insert a plastic opening tool into the seam between the front and back of the iPod. You may find it easier to carefully flex the putty knife downward in order to create more of a gap for the opening tool, but be sure not to bend the corner of the rear panel!

Near the center of the display, carefully insert a metal spudger into the gap created by the plastic opening tool. It is easy to create a noticeable bump in the rear panel here that is difficult to repair. When prying the tab free, try to have the metal spudger pivot on the edge of the rear panel rather than bending the rear panel outward.

Using the metal spudger, disengage the single clip on the top of the iPod.

Near the other top corner, insert an opening tool into the seam between he front and back of the iPod

On the other side, insert an opening tool into the seam between the front and back of the iPod. You may find it easier to angle the opening tool stuck in the top corner in order to create a sufficient gap.

Remove the plastic opening tool from the top corner and insert it into the seam between the front and back of the iPod, leaving at least 1.5 inches of space between the two tools (as done on the other side).At an angle, carefully insert a putty knife about 1/8 inch into the seam between the two opening tools. Again, there are thin metal rails running along the inside of the rear panel, so take great care when inserting the putty knife. Once the putty knife has cleared the lip of the rear panel, angle the putty knife so that it is vertical, and carefully (but firmly) wiggle it straight down into the iPod via the gap between the plastic opening tools. Push with your fingers on the rear panel behind the putty knife to minimize bending. Ever so slightly flex the putty knife to ensure that most of the metal tabs on this side of the iPod are disengaged.

The metal clips near the corners are notorious for tenaciously gripping the front panel. It is necessary to disengage these clips in order to open the iPod. Carefully insert a metal spudger into the area near the stubborn metal clip.

Gently wiggle the metal spudger down so that it is all the way in the rear panel.

Gently begin to disengage the clip from the front panel. It is easy to create a noticeable bump in the rear panel here that is difficult to repair. When prying the tab free, try to have the metal spudger pivot on the edge of the rear panel rather than bending the rear panel outward

Continue to push up on the front panel with the metal spudger until the metal clip releases.

There are two ribbon cables connecting the rear panel to the rest of the iPod. In the following step, be careful not to damage these ribbon cables. Grasp the front panel assembly with one hand and the rear panel with the other. Take a deep breath! Gently (GENTLY) disengage the remaining clips on the rear panel by pulling the tops of the front and rear panels away from each other (think of the bottom of the iPod as a hinge), taking great care not to damage the ribbon cables holding the two halves together.

Use a spudger to slide up the connector holding the orange battery ribbon in place. You only need to lift the locking bar up about 2 mm to free the cable. Slide the orange battery ribbon out of its connector.

Place the rear panel next to the iPod, being careful not to strain the orange headphone jack cable.

Lift the hard drive up with one hand so you can access the headphone jack ribbon beneath.
Use a spudger to flip up the plastic tab holding the headphone jack ribbon in place. The tab will rotate up 90 degrees, releasing the ribbon cable.
Slide the orange headphone jack ribbon out of its connector.
The rear panel is now free from the iPod.

Now to repair the damage caused by liberating the internal parts of the iPod Classic! It is highly likely that at least one of the metal clips in the lower case has been bent upward. These clips must all be pointing downward in order to reinstall the rear panel. Take the broad, flat side of the metal spudger and push the clip down, taking care not to tear the thin metal rail from the rear panel. Be careful not to damage any of the headphone jack parts while shaping these clips!

On a clean, hard surface, lay the rear panel on its side. Carefully but firmly push down on it, rolling the entire lip side back into its proper spot. It may be necessary to do this multiple times in order to achieve optimal straightness on the sides. It is better to have the edges of the case pushed in slightly too far rather than not far enough, because the reseating of the front panel will bend the rear panel into its correct alignment. Now that the rear panel is back to a beautiful condition, you can move on to repairing the iPod.

Rotate the hard drive out of the framework and place it so that the connector is facing up. Use a spudger to flip up the plastic tab holding the orange hard drive ribbon in place. The tab will rotate up 90 degrees, releasing the ribbon cable.

Slide the orange hard drive ribbon cable directly out of its connector. If you are replacing the hard drive in your iPod and it did not come with the rubber mounting brackets and foam padding, transfer these items from your old drive to the replacement drive.

Lenovo N500: How to verify the symptoms 
1. Turn off the computer.
2. Remove the battery pack.
3. Connect the AC adapter.
4. Make sure that power is supplied when you turn on the computer.
5. Turn off the computer.
6. Disconnect the AC adapter and install the charged battery pack.
7. Make sure that the battery pack supplies power when you turn on the computer.
If you suspect a power problem, see the appropriate one of the following power
supply checkouts:
“Checking the AC adapter”
“Checking operational charging”
“Checking the battery pack”
Checking the AC adapter
You are here because the computer fails only when the AC adapter is used.
 If the power-on indicator does not turn on, check the power cord of the AC adapter for correct continuity and installation.
To check the AC adapter, follow the steps below:
1. Unplug the AC adapter cable from the computer.
2. Measure the output voltage at the plug of the AC adapter cable. See the following figure:

Note: Output voltage for the AC adapter pin No. 2 may differ from the one you are servicing.

3. If the voltage is not correct, replace the AC adapter.
4. If the voltage is acceptable, do the following:
Replace the system board.
Note: Noise from the AC adapter does not always indicate a defect.

Checking operational charging
To check whether the battery charges properly during operation, use a discharged battery pack or a battery pack that has less than 50% of the total power remaining when installed in the computer.
Perform operational charging. If the battery status indicator or icon does not light on, remove the battery pack and let it return to room temperature. Reinstall the battery pack. If the charge indicator or icon is still off, replace the battery pack.
If the charge indicator still does not light on, replace the system board. Then reinstall the battery pack. If it is still not charged, go to the next section.
Checking the battery pack
Battery charging does not start until the Power Meter shows that less than 95% of the total power remains; under this condition the battery pack can charge to 100% of its capacity. This protects the battery pack from being overcharged or from having a shortened life.
To check your battery, move your cursor to the Power Meter icon in the icon tray of the Windows taskbar and wait for a moment (but do not click it), and the percentage of battery power remaining is displayed. To get detailed information about the battery, double-click the Power Meter icon.
Note: If the battery pack becomes hot, it may not be able to be charged. Remove it from the computer and leave it at room temperature for a while. After it cools down, reinstall and recharge it.
To check the battery pack, follow the steps below:
1. Turn off the computer.
2. Remove the battery pack and measure the voltage between battery terminals
1 (+) and 7 (-). See the following figure:

3. If battery output voltage is less than +3.9V DC, the battery is damaged, replace it. If battery output voltage is less than +9V DC, perhaps the battery has entered into over discharge protection mode, pre-charge the battery with AC, replace the battery if battery capacity cannot be charged over 0% within 2 hours.

4. If the battery output voltage is more than +9V DC, measure the resistance between battery terminals 5 and 7. The resistance should be 4 to 30 KΩ. If the resistance is not correct, replace the battery pack. If the resistance is correct, check the system board function.
