Lenovo Legion Y520-15IKBN Battery Replacement

简介

If your laptop will not start up or stay charged you may need to replace the battery. It is not a difficult project and the hardest part will be prying the back piece off.

For your safety, discharge your battery below 25% before disassembling your device. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

Shut down and unplug your device before beginning.

    • Flip the laptop on its side and wedge a spudger between the base panel and chassis, then pry around the perimeter until the base panel releases.

    • To get a better grip you may want to open the laptop slightly.

    • Lift the bottom panel off of the chassis.

    • During reassembly, make sure that the bottom panel clicks back into place on all four sides of the laptop.

    • Disconnect the battery connector by pulling the battery cable directly out of its port, toward the battery.

    • Do not pull on the socket itself or you risk damaging the motherboard.

    • If necessary, apply force and slowly wiggle the connector out of its socket. It should work its way out slowly.

I’ve damaged mine at step 4 and i don’t know how. Now the plug is loose and at the slightest touch, it goes into failure…I don’t now how to solve this, maybe replace the socket on the board by a new one. :(

Hello
I dont know if you are gonna read this, but you could try to glue the connector with Superglue to the board, but watch out to not tear it off or put superglue into the connector.

Has anyone had issues with Legion Y520 laptop saying that the "battery isn't recognized" (with the x through it via the icon in the taskbar) after swapping the battery? I have tried three different ones that all do the same thing (one is even an OEM Lenovo Legion Y520 battery). I am thinking that either, the machine wants it to be an OEM one (not a third party one) and has some sort of check done after POST to verify if it is an official battery or not (and the one I have is just DOA?) or that there is an issue with the connector on the board itself?
