My 2011 MacBook Pro...
Posted by: Rolando
Date: June 18, 2023 06:37PM
Fired up my 2011 MacBook Pro to check on something, and the trackpad felt funny... stiff.

The left side appears to bee slightly high, no longer sunken below the level of the wrist rest area, but the right side still is.

Guessing the battery is swollen.

Can I run this Mac on power adapter only and pull the battery, or should I get rid of it?

Any other suggestions?

EDIT: This is the 2nd Battery. I did replace the original, barely running, but not swollen battery with a model from our sponsor. Kept it going. Now I keep the old one as a museum piece, and to run an old Photoshop on the OSX Lion Partition.

Will probably just remove the battery, my 9 month old M1Pro MBP is wonderful!

Any idea what to do with a swollen Li Ion battery?

Yes, a swollen battery.

Off the top of my head, I don't know if it will run without a battery but you can get a new battery from our sponsor and replace it yourself.

It will run without the battery however it will only run at it's minimum 800 MHz speed and not the 3.x GHz it's supposed to run at. You will notice the new slowness quite a bit but it'll still run.

PM me if you're interested in getting a new battery, I may just have a line on a really good deal for you.....

IIRC, OWC sells a battery for that model.



It is what it is.

Battery is probably the problem but also could be need to clean and reseat the track pad switch. Check online for videos on that .

13" integrated GPU or 15" with both integrated and discrete GPU, the discrete one which will fail, not if but when. I reflashed my FPGA to bypass it completely.

Refresh the FPGA?, must be for professional user only? Or one with the proper equipment?. Have a 2011 and no problems as of yet.

Reflash, not refresh.

I bought the Lattice HW-USBN-2A ICSP FPGA Programmer from eBay and a pogo pin kit also from ebay. I think you need to make sure the pogo pin kit has 0.5 1.27 mm pitch (I was thinking of 0.05"). Let me see if I can find the link to what I got


EDIT: this is the pogo pin kit, 1.27 mm pitch

And this is the reprogramming tool
