Will a swollen macbook pro battery cause the machine to reboot intermittently

Dear mineng: I'm assuming that when you upgraded the ram you reinstalled the back cover correctly.Yes a swollen battery can cause a rebooting problem insofar as it may start to fail. Assuming that the battery is bad ( I think there's a way to show how many cycles it has remaining? coconut-battery??)** then it needs to be replaced. This you can do yourself, with the help of some tools, time and a new battery. try ifixit.com for a rough guide on how to do this

or....take it in to your local iFruit store

** apparently, if you Option+Click on the battery icon in the menu bar, it'll tell you something....

I don't know if your MacBook Pro has an easily replaceable battery or not. if not, see the ifixit thing

A swelling battery can fatally damage other internal components. Stop using the computer and get it to an Apple Store for a battery replacement NOW.

Your model does not have what Apple considers to be a user-serviceable battery. They do not sell batteries as replacement parts, only installing them in-store while you wait. Avoid batteries sold by third parties. Many are counterfeit and were defective before they left whatever sweatshop made them.

An expanding battery should be taken out immediately. It matters not if the CPU is throttled. What matters is the very real possibility of damage to the MBP. Allan Jones is 100% correct.
