Thanks a lot for the clear and thorough guidelines, worked like a charm and saved my 2-year old C940 after its original battery has bloated on its own!

Purhcased a replacement laptop battery from CanadaLaptopBattery, they shopped it from overseas (AlosteCell). Followed this guide to replace the battery. Replacing that little rubber piece was probably the biggest pain in the butt (the wire for the right speaker wraps around the rubber at the bottom as you squeeze it in). Thanks to the guide, this was one of the rare times I grabbed the right Torx bit first-try! Just a note; My laptop took several minutes after putting the new battery in (as well as being plugged in) to turn on. The laptop was on as indicated by the powerlight on the side, and the laptop was charging (orange light on the other side), but probably took 2-3 minutes to POST (Lenovo logo on screen). Just thought I'd mention that in case anyone freaks out.

Thanks for the helpful instructions! I have a question though: do you think it’s a bigger problem that I didn’t get the little screw underneath the small rubber thing back in? Because the new battery was built in a way that it wouldn’t fit.
