MacBook Pro early 2011 random shutdown

Hi,

I have a Macbook Pro Early 2011. 4 years ago, I replaced the keyboard. Two years ago, I believe the logic board was replaced due to a faulty GPU that was a known issue. A couple of weeks back, I started receiving warnings that the battery should be replaced. Soon after, the laptop would randomly shut down. I recently replaced the battery so I do not have the battery replacement warning anymore but the random shutdown has not disappeared.

I have noticed that it happens more when I am running on battery power. Example. I have downloaded Cinebench’s GPU/CPU tester. When running on power adapter, the test runs fine but if I run the test on battery, the laptops shuts down as soon as the CPU test starts (Even if I have full battery).

All help is appreciated!

Try downloading and install Coconut Battery to see if the new battery is according to standards..if you enclose a screenshot of what you see with your answer it might help evaluation. Sounds like there’s a problem with peak power requests, that’s understandable with an old battery but not with a new one..it might be you got a troublesome replacement.
