Motorola Atrix HD:  DISASSEMBLING PROCEDURE 

How to remove LCD & Touch Screen

On the bottom left hand side of the Motorola Atrix HD is the door for the SIM card and MicroSD.
Open the door and remove the cards before proceeding with your disassemble.
To take the back cover off the phone, use the plastic opening tool to pry it off. Un-snap each clip carefully as you work around the perimeter of the phone.

Remove the back cover from the Motorola Atrix HD.

There is a small amount of adhesive on the center of the back to attach it to the battery. Using the spudger, separate the adhesive to free the back cover from the phone.

There are ten T5 torx head screws that secure the rear chassis onto the phone. Use the T5 torx bit screwdriver to remove these screws and free the chassis.

Once all of the screws are removed from the chassis, utilize the plastic opening tool to separate the rear chassis from the body of the Motorola Atrix HD.

How to remove Speaker Assembly

With the rear portion of the chassis removed, use the pointed end of the spudger to gently pry the speaker assembly up out of its location. It is held down with a small amount of adhesive.
You can now remove the speaker assembly from the Motorola Atrix HD.

How to remove Battery

To remove the battery, go back to the main body of the phone. Using the appropriate screwdriver, remove the two T5 torx screws that secure the battery’s terminals down to the case.

The battery is also secured down by a small amount of adhesive. Using the spudger and battery pull-tab, pick the battery up out of its location in the phone.

Remove the battery from the Motorola Atrix HD.

The frame that housed the battery is secured to the body of the phone by ten T5 torx screws. Using the

T5 torx bit screwdriver, remove these screws.
With the ten screws removed, you can now remove the frame from the Motorola Atrix HD.

How to remove LCD

The touch screen connector is the first connection to be removed. Put the flat end of the spudger under the connection. Turn the spudger so it pulls the plug up and out of its socket.
Follow the previous steps to remove the LCD connection. The connection is next to the touch screen connector that was just removed.

The motherboard is next. Removing the motherboard from the phone will require the spudger in order to pry it up from the display assembly. Make sure the LCD is not stuck to the bottom of the motherboard with adhesive.

There are three layers to the phone: the touch screen, the LCD, and the motherboard.
If the LCD is stuck to the motherboard like ours, use the spudger to separate the LCD from the bottom of the motherboard.
Remove the motherboard from the Motorola Atrix HD.

Use the spudger, and a little force, to pry up the

LCD from the touch screen. The LCD and touch screen should now be separated.
Remove the LCD from the Motorola Atrix HD.

How to remove Touch Screen

To separate the touch screen digitizer from the front frame of the phone, use patience and the spudger to pry it up. With these, the separation will come easily.
The adhesive that secures the touch screen to the frame is minimal.
Remove the touch screen digitizer from the Motorola Atrix HD.

How to remove Front-Facing Camera

Now turn your attention to the motherboard. Use the spudger to pry up the front-facing camera connection.
With the connection out of its socket, remove the one
T5 torx screw that secures the camera assembly to the motherboard.

Use the spudger to maneuver the front facing camera from the Motorola Atrix.

Lenovo Z41-70 - Z51-70

To verify a symptom, follow the steps below:
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.

Restore of factory default

The Lenovo Z41-70/Z51-70/ideapad 500-14ACZ/ideapad 500-15ACZ computers come with pre-installed OneKey Recovery System. In order to save application files and the initial backed up files of the system, the hard disk in a Lenovo computer includes a hidden partition when it is shipped. If you need to restore the system to the point of your first boot up, just enter Lenovo OneKey Recovery System and run System Recovery.

2. Remove the battery pack and measure the voltage between battery terminals
1 (+) and 7 (-). See the following figure:

3. If the voltage is less than +11.0 V DC, the battery pack has been discharged.

Note: Recharging will be continued for at least 3 hours, even though the indicator does not light on.
If the voltage is still less than +11.0 V DC after recharging, replace the battery.
4. If the voltage is more than +11.0 V DC, measure the resistance between battery terminals 5 and 7. The resistance must be 4 to 30 KΩ. If the resistance is not correct, replace the battery pack. If the resistance is correct, replace the system board.

Battery pack removal

Unlock the manual battery latch 1. Holding the spring-loaded battery latch in the unlocked position 2, remove the battery pack in the direction shown by the arrow 3 .
