I need to replace the battery in my late-2013 rMBP due to swelling. The trackpad still works, but has limited clickiness, whilst the laptop itself rests on the aluminium backplate rather than the black rubber feet. I've read some stories and watched some DIY battery replacement videos where removing the backplate causes a lot of tension, making removal of additional screws difficult and subject to shearing. I'd like to avoid this, if possible, so I'm wondering if placing the MBP in a vise/clamp (with padding) would be advisable whilst removing the screws? Or is there something monumentally stupid that I've not thought about?
