What if the triwing screw is flattened by me

Hi everyone,

I just tried to use the triwing screwdriver to remove the battery of my MacBook Pro 15" i7. I managed to remove the 1st screw, however, the second one was gradually flattened by me and now it looks like a circle inside.

May I ask in this case, what should I do?

Many thanks for your answer in advance!

Can anyone be a little more specific on what tool I might need to get this out? I also have managed to flatten this exact Triwing with the tool i bought from this site.

That screw was SUPER tight and it's also a softer material than the screws in the bottom of the case. It really didn't take much to strip it; it didn't turn at all.

:(

you need a new MacBook Pro!

or maybe a small flathead screwdriver, it should be a little bit larger than the circle you created with the triwing - but be careful, there are many ways to damage the logicboard!

use the screwdriver and a little force to "fit" the blade into the circle, then try to unscrew the screw.

you can use a dremel or file to make a small straight groove in the middle of the screw head which will help with markus's suggestion of using a flathead screwdriver. it takes a bit of patience and some trial and error, but eventually you will be able to fit the flathead and remove the screw.

update

The answer I provided is pretty funny to me now... I had to do a teardown on mine and I stripped the EXACT same screw on the EXACT same model :)

I ended up using a small pair of grooved grooved pliers to turn the screw from the outside. Maybe this needs to be noted in the battery removal guide, seems like they extra-loctited that screw or something.

It is tricky to do on a small screw, but you can use a drill bit that is slightly smaller than the head of the screw to separate the head from the screw shaft. You can then use a pair of pliers to remove the remaining threaded piece of the screw that remains in the threaded hole. Sorry, This is a little difficult to describe with just words. Maybe I'll Try to get a picture of what I'm talking about.
