How to replace the mother board - Samsung Galaxy S5

Samsung Galaxy S5:  DISPLAY REPLACEMENT PROCEDURE 

Insert a fingernail or plastic opening tool into the divot to the left of the rear-facing camera. Gently pry and twist the flexible rear cover off the back of the phone.

Insert a fingernail or plastic opening tool into the recess in the bottom right corner of the battery and lift upward. Remove the battery away from the phone.

Using a fingertip, pull the microSD card straight down out of its slot. Remove the microSD card from the phone.

Repeat the above procedure to remove the SIM card.

Use a plastic opening tool to pry up the plastic midframe connector panel. Remove the connector panel with a pair of tweezers. There should be enough adhesive to readhere the panel upon reassembly, otherwise use a small amount of double-stick tape.

Use the sharp tip of a spudger to pry the home button cable connector straight up off its socket.

In the following steps you will be using an opening pick to separate the adhesive securing the front panel glass. Only pry where directed. If you experience resistance, stop sliding the opening pick and reapply heat. Insert the edge of an opening pick underneath the bottom right side of the front glass.

Slide the opening pick up along the right side of the display

Carefully slide the pick around the corner, stopping before the speaker grille at the top of the phone.

The adhesive securing the top of the phone is only a narrow strip above the earpiece speaker. Slide the pick along the top of the speaker to avoid damaging internal components. Slide the opening pick across the top of the phone, being very careful not to insert the pick too deeply.

Carefully slide the pick around the upper left corner. If you encounter any resistance from cooling adhesive, reapply a heated iOpener to the left side of the phone.

Slide the opening pick down along the left half of the phone stopping at the lower left corner.

Slide the opening pick all the way to the bottom left corner of the phone, making sure it is securely placed. In the following step you will be placing an iOpener over the home button end of the phone, you won't want your opening pick to slip out.

The bottom end of the phone contains the soft button and home button ribbon cables. If you insert the opening pick too far into the phone you risk cutting these cables. Slide the very end of the opening pick across the bottom edge of the display to separate the last of the remaining adhesive.

Twist the opening pick to detach the glass from the phone. If the front panel does not detach easily, it may require additional adhesive cutting.

If the front panel is not easily freed, the adhesive on the soft button cable may need to be separated. These cables are thin and easily damaged, therefore be certain you are only peeling them off the display assembly and not lacerating them. Insert an opening pick under the soft button icons on the display and pry the button cables down off the inside of the front panel.

Slightly lift, but do not remove, the home button end of display assembly. Do not remove the front panel entirely. It is still attached by a connector. If you are reusing the home button flex cable, be careful not to sever the cable from the home button. Adhesive can cause the cable to rip apart from the home button. While the home button will still work, the fingerprint scanner will not.

Use the sharp tip of a spudger to lift the front panel assembly cable connector straight up off its socket on the motherboard. Safely remove the front panel assembly from phone

Remove the ten 3.4 mm Phillips #000 screws from the display side of the midframe.

Flip the phone over and remove the following screws from the battery side of the midframe: Two 4.4 mm Phillips #000 screws near the USB port on the battery side of the phone
One 4.4 mm Phillips #000 screw

Gently run a plastic opening tool down along the left inner side of the interior frame to separate the three white plastic clips.

The midframe is composed of two halves that encase the motherboard. Gently pull the long sides of the silver bezel out away from the phone to separate the two halves of the midframe. It may be helpful to gently push in from the inside of the battery compartment, but be careful not to flex the interior half of the midframe, as the motherboard is mounted to it.

Continue on to the right side of the silver bezel, pulling away from the interior section of the midframe to separate the two halves.

Use a plastic opening tool to pry any remaining corners out of the silver bezel.

Carefully remove the interior midframe/motherboard assembly from the white inner midframe.

Carefully wedge the tip of a spudger underneath the antenna cable connector. Delicately lift the spudger directly upwards to disconnect the antenna connector off its socket on the motherboard.

Remove the single 3.0 mm Phillips #000 screw securing the motherboard to the midframe.

Pull, but do not remove, the camera end of the motherboard up from the midframe to allow access to the connectors on the rear. Do not attempt to fully remove the motherboard as it is still attached to the interior midframe by the Micro-USB port daughterboard connector.

Use the flat end of a spudger to pry the daughterboard connector straight up off its socket on the motherboard.

Use the flat end of a spudger to disconnect the front-facing camera connector off its socket on the motherboard. Remove the front-facing camera from the motherboard.

Use the flat end of a spudger to disengage the rear-facing camera connector straight up off its socket on the motherboard. Remove the rear-facing camera from the motherboard.

Lenovo ThinkPad P40 Yoga:  Power system checkout
To verify a power symptom, do the following:
1. Turn off the computer.
2. Connect the ac power adapter.
3. Turn on the computer. If the computer can be turned on, it means that either the battery pack or the ac power adapter is functional.
4. Insert a straightened paper clip into the emergency reset hole to reset the computer. If the computer is still powered on, it means that the ac power adapter is functional.
5. Turn off the computer.
6. Disconnect the ac power adapter and turn on the computer. If the computer can be turned on, it means that the battery pack is functional.
If you suspect a power problem, see the appropriate one of the following power supply checkouts:
“Checking the ac power adapter”

“Checking the built-in battery and operational charging”
“Checking the coin-cell battery”
Checking the ac power adapter
You are here because the computer fails only when the ac power adapter is used.
If the power problem occurs only when the docking station or the port replicator is used, replace the docking station or the port replicator.
If the system-status indicator does not blink three times when an ac power source is connected, check the power cord of the ac power adapter for correct continuity and installation.
To check the ac power adapter, do the following:
1. Unplug the ac power adapter cable from the computer.
2. Measure the output voltage at the plug of the ac power adapter cable. See the following illustration:

Note: Output voltage of pin 2 of the ac power adapter might differ from the one you are servicing.

3. If the voltage is not correct, replace the ac power adapter.
4. If the voltage is acceptable, replace the system board.
Note: Noise from the ac power adapter does not always indicate a defect.
Checking the built-in battery and operational charging
To check whether the battery charges properly during operation, do the following:
1. Discharge the battery until the remained battery power is less than 50%.
2. Connect the computer to ac power to charge the battery. If the battery status icon in the Windows notification area indicates that the battery is not charging, remove the battery and let it return to room temperature.
3. Reinstall the battery. If the battery is still not charging, replace the battery pack.
4. Check the battery status icon again. If the same error still exists, replace the system board.

Checking the coin-cell battery
To check the coin-cell battery, do the following:
1. Disconnect the battery connector.
2. Remove the coin-cell battery.
3. Measure the voltage of the coin-cell battery. See the following illustration.

If the voltage is correct, replace the system board.

If the voltage is not correct, replace the coin-cell battery.
If the coin-cell battery discharges quickly after replacement, replace the system board.
