Over the past few months I noticed a decrease in the battery life on my Apple MacBook Pro 15″. Initially the drop was not that significant but over time it became more noticable and a few weeks ago it began to turn itself off even though the battery was at a claimed 23%. I also realised that the power levels were falling quite dramatically even when the laptop was turned off.
As I do not use my MacBook on battery power all that often it didn’t bother me that much but last week I was using the MacBook on my lap on the train. I suddenly became aware that the bottom of the MacBook was getting VERY hot and the aluminium base was uncomfortably hot against my leg and the top was pretty warm too.
Realising that this was a sign that I should probably investigate what was going on I decided to unscrew the bottom of the MacBook and to take a look at the battery.
As I released the screws the bottom suddenly sprang open and the battery pack itself had burst!
So, if you have any of the symptoms above it’s definitely a good idea to either take a look at the battery or else take it to the Apple store and have them take a look at it for you. Who know’s what might have happened if I had continued to use it like this!
