LG Optimus G Pro – Disassembling procedure – How to remove the case – How to remove the battery


LG Optimus G Pro
Once you have access to the phone, there is a small indent on the bottom left side. Use your fingernail or a plastic opening tool to pry from here and pull off the back casing.
Once you have properly removed the outer casing, the back should look as so. To remove the battery, pull up from the red mark using your finger. The battery should come up at an angle, and easily be able to be removed. Once the battery is removed you may safely proceed to the next step.
Make sure you remove the battery first. You will see that there are 14 screws on the back of the inner case. Use the Phillips head screwdriver to remove each of the screws, make sure to put the screws in a safe place where they will not get lost.
Once you have removed all the screws, you can begin removing the inside cover. Insert the opening tool using a sliding motion into one of the corners and move it along the edges of the inside cover. This will loosen the edges and the inside cover will pry apart from the shell.
The inner cover is now removed, you now have access to the many parts on the inside of the phone.
Using a plastic opening tool, pry the connection between the cable and the phone. With even pressure the cable should disconnect from the logic board easily.
After removing the the Ribbon Cable, the Rear-Facing Camera should be able to be removed easily with your fingers.
Using your plastic opening tool, disconnect the connection between the phone and the ribbon cable. Make sure to use even pressure as you apply it to the cable.
In this next step it is easy to pry the wrong piece. Make sure to pry at the metal platform that the sister board sits on, not the orange printed circuit board itself. Using your prying tool, pry at the right red marked corner, making sure to pull at the metal platform under the circuit board. Once it is raised slightly, pull along the underside until the left red mark. This should loosen the board and allow it to be removed. If it's still unable to be removed, try to pry at the orange mark, making sure to pull at the same metal platform.
You can now raise and remove the sisterboard with your plastic opening tool or your fingers.
Use the plastic opening tool to disconnect the 4 ribbon cable connections and the antenna attached to the logic board.
The logic board is connected to the under side of the phone with a bit of adhesive. Using a spudger, place it under the logic board from the top right corner and gently slide it toward the center orange mark where the adhesive is. Apply a little bit of pressure parallel to the logic board and the Logic board should loosen from the phone.

Lenovo Y480 – Y580 – How to test the battery pack – How to test the AC Adapter – How to check the Optional charger


Lenovo Y480 – Y580
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 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.
How to remove the Battery pack
Unlock the manual battery latch. Holding the spring-loaded battery latch in the unlocked position, remove the battery pack in the direction shown by the arrow.

Jazz Ultratab C954 – Disassembling procedure – How to replace the battery – How to remove back cover – Tablet repair and service


Jazz Ultratab C954:  DISASSEMBLING PROCEDURE 
On the top of the tablet there are two 1cm screws that hold the back cover on. Locate these screws and remove them using a Phillips head #0 screw driver.
You now have to pry the back cover from the touch screen panel. To do this insert a plastic spudger into the seem. Then work your way around the panel until it is free. There are buttons on the top side of the tablet that go through the back cover. The cover must slide up when removed to avoid damaging the buttons.
This is what your tablet should look like once the back cover is removed. You are now ready to begin repairing your tablet. Follow the corresponding guide for instructions on repairing major components. To reattach the back cover begin by sliding the cover on making sure the buttons and the speaker are in their designated holes on the back cover. Then attach the two covers by pressing them together until you hear the plastic tabs interlock. With the two screens held together the last step is to put the two 1cm screws on the top of the tablet back in. Your tablet is now ready for use again.
First locate the battery on the tablet, all of the battery information is printed on the top of the battery. This information will allow you to purchase the correct battery for your tablet.
Before removing the battery it is necessary to detach the motherboard to allow yourself more room and to prevent damage. To do this remove the three Philips head screws marked by the red circles. These screws are also 1cm in diameter.
The two wires connecting the battery are located within the yellow box. They are soldered to the motherboard and must be cut. Using a pair of wire cutters cut each wire as close to the board as you can without damaging the board.
Now it is time to remove the old battery. Before removing the battery use a pencil to trace its location, this will allow you to place the new battery in the same place. The battery is glued to the screen and must be removed using spudgers. Gently peel the battery from the screen until it is free.
CAUTION: Be careful not to damage or tear the battery, it contains harmful materials and should not be opened or cut in any way.
Using a hot glue gun glue the new battery in place making sure the battery lines up with the marks you made and that the wires are facing the correct direction. You want the wires to be on the side with the motherboard.
Before connecting the new battery to the motherboard locate the positive and negative wire locations. You must connect the black wire to the (- ) location and the red wire to the (+) location.
It is now time to solder the wires in to their correct locations. To do this hold the wire on the old solder, using a small amount of solder melt the solder and wires to the old connection points. The black wire on the - location and the red wire on the + location. Soldering irons are very hot and can cause serious injury. If you do not know how to use a soldering iron please seek help from someone who is experienced.
With the new battery connected you can now re-secure the motherboard with the three screws you previously removed.
With the new battery fully connected you can now reattach the cover and begin to enjoy your tablet again. For instructions on reattaching the cover refer to the prerequisite guide on cover removal and attachment.

Apple Watch 42mm – Disassembling procedure – How to remove the AMOLED Display


Apple Watch 42mm:  DISASSEMBLING PROCEDURE 
Heat the screen up so that the entire display and watch are warm. Be sure to turn the device off first by holding down the crown then sliding to power off. Using a sharp blade start at the bottom right corner and lift the glass up enough to create a gap, once you have a large enough gap use a plastic tool to break the adhesive bond around the edges
Disconnecting the LCD assembly
When inserting the knife & plastic tools around the edges be sure not to go further than 1mm into the AMOLED. The force touch gasket lies directly underneath the glass and is easily damaged if pushed on too hard with a knife or other metal object. The FPC clip is tricky but is easily removed using sharp point tweezers on the battery edge.
Desoldering the proximity sensor power supply
use a solder iron tip that was larger than the solder pads. Turn your soldering iron up to a high temperature, 350C. DO NOT add any solder, just use the heat & tweezers to pull back the tabs. After unsoldering pull the flex cable out of the way and use tweezers to peel back the proximity sensor from the AMOLED. CAREFULLY.
Separating the Digi flex from the LCD
After desoldering use a plastic spudger in the exact area as the picture shows to loosen up the adhesive holding the digi flex in place. It's best if you use a small amount of heat, around 150F, to help soften the adhesive bond. Fold the digi cable back as shown in the second picture.
Separating the AMOLED from the glass
Begin by preheating the entire screen to a uniform temp, letting it sit under warm air for 10 minutes. keep heat gun on 300F-350F while holding the screen 3"-6" away from the nozzle to vary the temperature. Carefully insert a business card under the screen on the dig flex side. Use alcohol to weaken the OCA tape bond then move the card in slow
Keep inserting the card slowly while using alcohol as a de-bonder and lubricant as well as keeping uniform hot air blowing on the screen. While holding the outside of the glass continue rocking the card back and forth until the AMOLED is completely separated.
Cleaning the AMOLED
The AMOLED screen is extremely thin, but not as fragile as you might expect, remember to be gentle and use heat through the entire separation process. To remove the old OCA adhesive use your finger and "roll" the glue off, pure isopropyl alcohol also helps to de bond the adhesive. The screen is "waterproof" alcohol seeping into the edges is okay.
Tips
Be careful of the force touch flex cable that sticks into the frame on the bottom left of the display while removing the display assembly from the frame. The force touch gasket sits around the ENTIRE edge of the watch and is a thin silicone membrane. Test your AMOLED after separation before proceeding to the next steps.

Disconnect the touch screen & display flex cable. Remove the main board.
If the glass is broken, put some scotch tape to prevent it breake to pieces. Use a hot air to make adhesive tape more soften. For this operation you can use a hairdryer. Use a cutter and make small room to insert a plastic pick.
Continue with the separation by using a plastic tools. If necessary, use the hot air again
Unstuck the Touch screen flex cable from the display. If you have a broken glass, you can cut the touch screen flex cable, otherwise unsolder it careful like in the next step.
The display edges are glued to the glass with adhesive tape. Use only thin plastic tools for the separation.
Remove the blue sticker. With a soldering iron, remove the touch screen flex cable and install the new one. Put back the blue sticker.
If the spare part is without tape, install a new one.
Carefully put the display in place, then install the glass.
Start with reassembling.
