Lenovo ideapad G700 – G710 – How to test the Battery charge – How to test the battery pack Voltage

Lenovo ideapad  G700 – G710

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 KW. If the resistance is not correct, replace the battery pack. If the resistance is correct, replace the system board.

Samsung Galaxy Ace II – Disassembling procedure – How to remove the case – How to replace the display

Locate the small hole on the left side of the phone near the volume rocker, which you can slip your fingernail into to pull the battery casing off.
Remove the battery by pulling up on the small dip at the bottom, and slide the SIM sideways out of its enclosure. You can also tap the bottom of the phone with the display up against a surface to allow the battery to fall out.
Remove the 8 screws highlighted.
With the screws removed, push a spudger no more than a centimeter into the device. Gently pry all around the outside of the phone where the gray plastic meets the glass of the display.
The plastic backing will separate entirely from the device. You might have to force it a little, but don't use too much or you risk damaging the plastic or the internal components
Behold the motherboard of the phone. Remove the one screw holding down the motherboard. Do not try and remove the motherboard yet!
Gently spudge the power button connector off of the side of the device. Starting from the bottom right corner of where it is in the first picture is the best way to go about this. Gently disconnect the highlighted ribbon cable from the motherboard.
DO NOT PULL THE MOTHERBOARD AWAY FROM THE DISPLAY HOUSING YET! The last picture shows the ribbon cable connecting the speaker and headphone jack assembly. You do not need to disconnect this if you are only replacing the digitizer.
Gently lift up the side without the white plastic on it to see the ribbon cable plugged into the bottom. Pull this ribbon cable connector off with a plastic spudger and remove the motherboard from the display chassis.
If you need to replace the unit's main camera, it's right here for you to disconnect.
You now have exposed the Thin Film Transistor housing.
Disconnect this ribbon cable by flipping the black tab at the very left (relative to this picture) upwards to the right, and gently pulling the ribbon cable out.
Heat the entire front of the display up with a heat gun. A hair dryer will work as well. Stick a finger nail in an area with a small seam - I found one around the top right - and pry it open just enough to fit a spudger. Run it all the way along the edge of the display. There are no sensitive ribbon cables to break, but pay close attention to the silver speaker at the top, and the home button at the bottom.
You should also pull up on any surface of the digitizer which has separated from the metal TFT housing. This is to prevent it from re-sticking and introducing aggravation. While using a spudger to remove the adhesive, be sure to always drag the spudger along the digitizer side (towards the glass) and not towards the metal body, or you will scratch the TFT.
Carefully pull the ribbon cable connector through the slot here, ensuring it doesn't catch on any parts.
If you are replacing the digitizer, you do not have to be gentle to the ribbon cable but it is recommended anyway.
To reassemble, simply follow all these steps in reverse,

Samsung Galaxy Tab 10.1 4G – Disassembling procedure – How to replace the headphone jack

Samsung Galaxy Tab 10.1 4G

Power off your tablet before you begin disassembly.
Screen side facing you, rotate device 180 degrees so the SAMSUNG" logo is upside down.

Using the plastic opening tool, start in the center near the charge port and wedge the angled tip between the plastic back and the glass screen.

Create a wedge and apply pressure. Use the tool to separate the screen from the back until you hear an audible “pop."
Continue to wedge the tool about every inch along the current edge.

Once the bottom edge has been loosened, work towards a bottom corner from the other edge and continue to wedge gently until you can “pop” the corner out.

Continue this process on the other bottom corner until it can be popped out as well.

Place your hand between the device and the back panel. Then continue the wedging motion along the top edge of the device until the back panel comes loose.

Do not wedge the tool directly on top of the power buttons and headphone jack. Wedge nearby so that you don’t damage internal hardware.

Remove the back from the device.

Excessive force shouldn't be necessary here. If the back panel is sticking, find the area of the edge closest to the sticking point and wedge the opening tool there until the back panel pops free.

When working with electronics, it's important to choose a tool that's ESD-safe to avoid accidental damage to the device. The regular black nylon spudger or a plastic opening tool should be used whenever possible.

The connection between the battery and motherboard is a group of four wires in black housing that can be found near the top middle of the device. Using a plastic spudger or a flat, slim tool, lift the black connector housing upwards to disconnect it.

Use a Phillips #00 screwdriver to remove all 4 black 2.5mm screws securing the silver SIM card reader to the motherboard.

Using a plastic spudger, gently pop the SIM card reader connection off the motherboard.

There are 5 connection points all in a row. The one you want to pull off is the one furthest to the left.

Lift up SIM card reader and remove it.

You should be able to just pick it up with your fingers. If the piece is hard to grasp, slide the metal spudger tool under the reader to lift it.

Lift the SIM card reader off the motherboard, and replace it with a new SIM card reader.

Be sure to retrieve your SIM card from the old reader.

Using a plastic spudger, gently lift the connector off of the motherboard.

When working with electronics, it's important to choose a tool that's ESD-safe to avoid accidental damage to the device. The regular black nylon spudger or a plastic opening tool should be used whenever possible.
If you have removed the SIM card properly, the headphone port connector will now be the furthest left connector.

Firmly tug on the connector to remove the headphone jack.

If necessary, use the metal spudger tool to pry the headphone jack out of it's housing -- it will be attached with some strong adhesive.
Don't worry about losing adhesive, your new headphone port will have new adhesive for you to apply.
