Apple iPod Shuffle – Disassembling procedure – How to remove the case – How to remove the Battery

Apple iPod Shuffle:  DISASSEMBLING PROCEDURE 

Before beginning, be sure your Shuffle is turned off as shown.

Use the edge of an iPod opening tool to pry the plastic cover off the headphone jack side of the Shuffle.

Remove the plastic cover and set it aside.

Remove the two Phillips screws from the headphone jack side of the Shuffle.

Use the edge of an iPod opening tool to remove the steel cover from the headphone jack side of the Shuffle.

Use the edge of an iPod opening tool to pry the plastic cover off the controls side of the Shuffle. Remove the plastic cover and set it aside.

Use a pair of tweezers to remove the hold and shuffle sliders from the Shuffle.

Remove the two Phillips screws on the controls side of the Shuffle.

Use the edge of an iPod opening tool to remove the steel plate from the controls side of the Shuffle.

Use the edge of an iPod opening tool to slightly pry the steel plate on the headphone jack side of the Shuffle away from the lip cut into the outer case.

Use your iPod opening tool to push the logic board assembly out of the outer case enough to grab the logic board by its edges. Pull the logic board assembly out of the outer case.

Use the edge of an iPod opening tool to peel the adhesive under the battery that secures it to the logic board.

Flip the battery upwards to reveal the solder pads soldered to the logic board. Before desoldering the battery, be sure to scrape the protective resin off both solder points.

Desolder the battery from the logic board by heating up the solder joint with a soldering iron and simultaneously using a pair of tweezers to pull the battery wire away from the logic board.Do not touch the + and - leads together.

Apple iPhone 6 – How to replace the display shield of Apple iPhine 6 Apple iPhone 6

Display shield replacement procedure

Power off your iPhone before beginning disassembly. Remove the two 3.6 mm Pentalobe screws next to the Lightning connector.

The next three steps demonstrate using the iSclack, a great tool for safely opening the iPhone 6 that we recommend for anyone doing more than one repair. If the plastic depth gauge is attached at the center of the iSclack, remove it now it's not needed for larger phones like the iPhone 6. Close the handle on the iSclack, opening the suction-cup jaws.

Place the bottom of your iPhone in between the suction cups. Position the iSclack's upper suction cup against the display, just above (but not covering) the home button.

Open the handles to close the jaws of the iSclack. Center the suction cups and press them

firmly onto the top and bottom of the iPhone.

Hold onto your iPhone securely and close the handle of the iSclack to separate the suction cups, pulling the front panel up from the rear case. The iSclack is designed to safely open your iPhone just enough to separate the pieces, but not enough to damage the display cables. Peel the two suction cups off your iPhone.

Front Panel Assembly

If you don't have an iSclack, use a single suction cup to lift the front panel: Press a suction cup onto the screen, just above the home button.

Be sure the cup is pressed securely onto the screen to get a tight seal.While holding the iPhone down with one hand, pull up on the suction cup to slightly separate the front panel assembly from the rear case. Take your time and apply firm, constant force. The display assembly is a much tighter fit than most devices.

Using a plastic opening tool, begin to gently pry the rear case down, away from the display assembly, while continuing to pull up with the suction cup.

There are several clips holding the front panel assembly to the rear case, so you may need to use a combination of the suction cup and plastic opening tool to free the front panel assembly.

Pull the plastic nub to release the vacuum seal on the suction cup.

Remove the suction cup from the display assembly.

Pull the home button end of the front panel assembly away from the rear case, using the top of the phone as a hinge.

Keep the front panel supported at a 90º angle in relation to the rear case until you remove it allowing it to fall flat will strain the display cables and their connections on the logic board.

Several clips along the top edge of the front panel form a partial hinge, allowing the front panel assembly to swing open like a book. During reassembly, align the clips just below the top edge of the rear case. Then, slide the front panel upward until its top edge is flush with that of the rear case.

Remove the following five Phillips screws securing the front panel assembly cable bracket:

Three 1.2 mm screws

One 1.7 mm screw

One 3.1 mm screw

Remove the front panel assembly cable bracket from the logic board.

In the next four steps, take care to pry up only on the cable connectors, and not on their sockets on the logic board.

Use the flat end of a spudger to disconnect the front-facing camera and sensor cable connector.

Use the flat end of a spudger to disconnect the home button cable connector.

Use the flat end of a spudger to disconnect the display data cable connector. When reassembling your phone, the display data cable may pop off its connector. This can result in white lines or a blank screen when powering your phone back on. If that happens, simply reconnect the cable and power cycle your phone. The best way to power cycle your phone is to disconnect and reconnect the battery connector.

Use the flat end of a spudger to disconnect the digitizer cable connector.

Remove the front panel assembly from the rear case.

Remove the two 1.9 mm Phillips #00 screws securing the home button bracket.

Remove the home button bracket from the front panel.

Use the point of a spudger to disconnect the home button cable connector by pushing it up and away from the home button.

Remove the following Phillips #00 screws securing the LCD shield plate to the front panel:

One 1.7 mm screw

Six 1.6 mm screws (three on each side)

Lift the front-facing camera end of the LCD shield plate up slightly. Do not attempt to remove the shield plate entirely, it is still attached to the front panel via home button cable.

Slide the point of a spudger behind the shield plate to gently lift the home button cable up off of the front panel.

Remove the LCD shield plate.

Peel the black backing tape away from the home button cable. You may need tweezers to start peeling, however the tape is brittle and it may be hard to complete the job with tweezers alone.

Carefully peel the home button cable up off of the adhesive holding it to the LCD shield plate.

Lenovo ideapad 310 – AC adapter testing procedure – How to remove the key board – How to test the babttrey pack

Lenovo ideapad 310:  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.
