Apple iPad Wi-Fi – How to replace the Speakers

If your display glass is cracked, keep further breakage contained and prevent bodily harm during  your repair by taping the glass.
Lay overlapping strips of clear packing tape over the iPad's display until the whole face is covered.
This will keep glass shards contained and provide structural integrity when prying and lifting the display.
Do  your best to follow the rest of the guide as described. However, once the glass is broken, it will likely continue to crack as you work, and you may need to use a metal prying tool to scoop the glass out.
Wear safety glasses to protect your eyes, and be careful not to damage the LCD screen.
Insert a metal spudger between the top edge of the display assembly and the rear panel assembly.
Rotate the spudger away from you to release the tabs along the top edge of the display.
Insert a second metal spudger between the top edge of the display assembly and the rear panel assembly to keep the tabs from snapping back into place.
With one spudger, work your way along the right edge of the iPad.
The front panel is held to the aluminum back by metal clips on the top, bottom, and left sides. The right side has plastic tabs which slide into recesses in the backplate.
Once the clips are released, lift the left side of the front panel up and slide it to the left to clear the tabs from the aluminum backplate.
Lift the display assembly away from the rear panel assembly by its bottom edge.
Do not attempt to remove the display at this time, as it is attached to the rear panel assembly.
In the following steps, you will disconnect the three cables attaching the display assembly to the logic board. The cables are for the following components:
Digitizer
Ambient Light Sensor
Display Data Cable
Use the edge of a plastic opening tool to flip up the retaining flaps holding the digitizer ribbon cables in their sockets on the logic board.
Be sure you are flipping up the retaining flap, not the socket itself.
Pull the digitizer ribbon cables straight out of their sockets.
Use a plastic opening tool to remove the ambient light sensor connector from its socket by gently prying upward.
Disconnect the display data cable from the main board by flipping up the metal retainer by its black plastic pull tab.
Pull the cable connector away from its socket.
Pull the connector parallel to the face of the logic board.
Remove the display assembly from the rear panel assembly.
Remove the two 4.56 mm T5 Torx screws securing the dock connector cable to the main board.
Remove the single 2.84 mm T5 Torx screw connecting the dock connector cable to the rear case assembly.
Remove the two 2.84 mm T5 Torx screws securing the dock connector cable to the rear panel assembly.
Carefully remove the plastic cover over the WiFi/Bluetooth board and dock connector cable using a plastic opening tool.
Pry the Wi-Fi and Bluetooth antennas up off their respective sockets on the Wi-Fi/Bluetooth board.
Remove the dock connector cable from the rear panel assembly.
Use the edge of a plastic opening tool to disconnect the speaker connector from the logic board. Pry up from beneath the wires.
Remove the two 2.84 mm T5 Torx screws securing the speaker assembly to the rear panel assembly. If necessary, remove the tape covering the Wi-Fi cables.
De-route the Wi-Fi antenna through its channel in the speaker assembly.
Deroute the speaker cable connector through the left side of the rear panel assembly.
Lift the speaker assembly and push it forward until the ports clear the bottom side of the rear panel assembly.
Remove the speaker assembly out of the rear panel assembly.

Lenovo YOGA 910 – Disassembling – How to check the AC adapter – How to check and remove 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.
If the computer does not charge during operation, go to “Checking operational charging”.
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 fgure:
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 is not lit, 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 is still not lit, replace the system board.
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.
