LENOVO IDEAPAD Z560 – HOW TO TEST THE AC ADAPTER VOLTAGE – HOW TO TEST THE BATTERY PACK

Lenovo IdeaPad Z560 – How to test the AC adapter Voltage – How to test the battery pack

Lenovo IdeaPad - Z560

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.
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 overdischarge protection mode, pre-charge the battery with AC, please replace the battery if battery capacity can not 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.

LG G PAD 10.1 – HOW TO REPLACE THE MOTHER BOARD

LG G Pad 10.1 – How to replace the mother board

LG G Pad 10.1: MOTHER BOARD REPLACEMENT PROCEDURE 

To remove the back panel of the device, start by attempting to fit the plastic opening tool in the crease between the screen and the back panel of the tablet.
You can use your hands to push against the corners of the device to attempt to make the gap larger for your plastic opening tool to fit in. If you are replacing your screen because it is damaged, it may be useful to pick away at some of the glass to expose the clips in the edges of the plastic.
Insert the corners of your plastic opening tool into the slots that are on the very outside edge of your device to start disconnecting the panel.

Once the edge of your device's panel is separate from the screen, continue moving around the outside of the device while continuing to pry the two pieces apart from each other.

Insert another plastic opening tool (or a similar tool) between the screen and the back panel on the opposite side of the device to hold it open.

There is a piece of double sided tape on the back of the battery holding it in place. Pull the battery with enough force to pull it apart from the tape.

Remove the five 2 mm Phillips #000 screws securing the motherboard.

The silver EMI shield may come off during this step. Just set it aside until reassembly.

Remove the two 5 mm Phillips #000 securing the motherboard,

Disconnect the cable from the battery to the motherboard by grabbing the cable and pulling upwards.

Using the spudger, pry up the connector on the motherboard from the back camera to disconnect it.

Then move to the front camera towards the end of the motherboard and disconnect that by using the spudger to pull up on the clip.

Now that all of the wires and screws are disconnected, use the spudger or a prying tool on the bottom corner of the motherboard to release it from one of the clips holding it in place.

Once the corner is removed, repeat the same action at the far end of the motherboard to release the second clip.

LG G Pad 10.1:  disassembling procedure 

To remove the back panel of the device, start by attempting to fit the plastic opening tool in the crease between the screen and the back panel of the tablet. You can use your hands to push against the corners of the device to attempt to make the gap larger for your plastic opening tool to fit in. If you are replacing your screen because it is damaged, it may be useful to pick away at some of the glass to expose the clips in the edges of the plastic. Insert the corners of your plastic opening tool into the slots that are on the very outside edge of your device to start disconnecting the panel.

Once the edge of your device's panel is separate from the screen, continue moving around the outside of the device while continuing to pry the two pieces apart from each other.

Insert another plastic opening tool (or a similar tool) between the screen and the back panel on the opposite side of the device to hold it open.

There is a piece of double sided tape on the back of the battery holding it in place. Pull the battery with enough force to pull it apart from the tape.

Locate the cable connection from the motherboard to the screen. It is a rectangle chip on the edge of the motherboard. Use the spudger to pry the clip to disconnect it.

You need to melt the glue holding the screen to the device. Turn on your heat gun or hair dryer and hold it approximately one-inch from the edge of the device. This step may take some time, so be patient. Continue melting the glue around all edges of the device.

When the glue is melted, it is time to remove the screen from the device. Starting at the corners, use the suction cup to pull up the screen as much as possible. The screen should lift enough to fit the plastic opening tool in the gap. If the screen is not pulling up at all, continue to use the heat gun or hair dryer to melt the glue before returning to this step.

Once the screen starts to detach from the device, insert the plastic opening tool into the gap and begin to pry the screen. Continue prying the screen by slowly sliding the plastic opening tool around the edges of the device until the screen loosens. It may take several tries to get the screen to detach from the device. Every time you circle the device with the plastic opening tool, be sure to put increasing amounts of pressure to release the glass. Since the glass is being replaced, it is okay when it starts to crack. This may even make this step easier.

Use the plastic opening tool to push the screen up entirely from the device, You may need to use your hands for this. If you do, it is advised to use gloves to avoid any of the broken glass from getting in your hands. If the screen is still hard to remove at this step, continue using the heat gun or hair dryer to melt the remaining glue while you are trying to pull up the screen.

Now that the screen has been removed, clean up the remaining glue and glass shards around the edges of the device.
