TIP: bevore putting in the new batterie, check that the batterie connector is centered, and alingned with the main board. Else you cannot nicley plug in the connector and the battery cannot be screwed in any more.
Thank you for putting this together. I’m back again with my notebook. It took me 4 hours, and I skipped steps 5 to 34.
In my case it leaked through the trackpad…. I had a transparent film (instead of aluminium) and it did not damage the screen.
I skipped steps from 5 to 33 and directlychanged the battery (before disassembling all). Worked fine.
