Lenovo YOGA 710-14ISK - YOGA 710-15ISK – How to check the ace adapter – Disassembling procedure – How to replace the battery

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. 5 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.

NOTE THIS FLEXIBLE RIBBON

Carefully lift up the board from the left-hand side allowing it to 'hinge' on the metallic ribbon connector you have just noted and allow it to lay flat

The freed connector for the screen should have unfolded

Now the screen can be pried from the outer case, but take care as you do so not to tear the metallic ribbon between the two casings

To detach the screen it can help to use a pry tool to push the screen from behind through the slot

The screen is detached and the connector can be wiggled out through the slot

Remove the old screen and connector altogether

The connector for the new screen now has to be wiggled back through the slot

Once the connecter is pushed through the slot, you should now stick the new screen into place using suitable adhesive strip.

Fold down the ribbon connector from the screen and carefully fold the two casing halves together again, making sure that the two connectors are sticking out of the side.

Reconnect the two connectors on the right hand side by pressing down

Reinsert the ribbon connector on the left hand side and push down the retaining catch.
