Painless battery replacement

Mi Problema

Started getting "Service Battery" message and the battery was only lasting about 2 hours on a full charge. Plus the computer seemed to be running warm a lot.

Mi Solución

Very simple. This is one of the best Mac laptops for DIY service Apple ever built. Ten screws on the back and the four most serviced components (memory, hard drive, optical drive and battery) are right there. I've been in there before to max out memory and upgrade to a 1TB hard drive (thinking about SSD options, but macOS Sierra isn't going to support this model, so we'll see) so this repair was familiar territory. The battery replacement was a piece of cake.

An added benefit, my track pad, which I thought was failing, works normally again. It seems that the old battery was bulging in several places and preventing one corner of the track pad from moving. Glad that old battery is out of here!

Mi Consejo

Don't delay if your old battery isn't doing the job. There is nothing to fear if you follow this guide.
