I had a very similar experience . I had a battery start swelling , and it started getting really hot so I took the back off to take the battery out to prevent the logic board from getting damaged . When I opened it , the battery plastic looked like it was melting and it eventually ruptured burned a hole through the plastic . There were several holes ranging in size from a grain of rice to about 14 the size of a dime . I took it in thinking I was going to have to pay for a new battery or possibly a new laptop since it was well out of the warranty period and walked out about 15 minutes later with a brand new MBP . <| sep |> Agreed . Twenty spankings seems like the bare minimum . <| sep |> I didn ' t know , and it ' s hilarious !
