How to remove a small dent on MacBook Pro 13 2022

I agree with @steve359 that a case is a bad idea. Every time I work on a laptop with one of these cases and remove the case there has been all sorts of disgusting dirt & grime inside the case which has actually damaged the finish of the laptop. Plus the cases are always cracked and split with many of them loose. I've almost dropped a few laptops because the laptop slid out from the broken case. Plus it can be very difficult to remove the case from the Display Assembly (aka lid) as some cases are extremely tight which could possibly lead to the glass or LCD panel becoming cracked which definitely would necessitate an extremely expensive repair to even continue using the laptop. I hate removing "protective" cases from any devices for these reasons.

Except for having the damaged part replaced which is very expensive ($600+ US), there is no way to remove any dents from the laptop for multiple reasons. The display cannot be taken apart to even access the inside of the aluminum panel plus trying to remove any dents/blemishes will just make it worse. Just ignore the blemishes as every laptop will get them over time.

There is really no practical way to do as you wish.

To begin with, you'd have to remove all the internal and some how beat out the dent in much the same way dents are remedied on car bodies.

Then you'd have to have the body painted to match colors. I'd imagine a bit of "Bondo" would be involved along with some pretty precise sanding. Then comes the putting all the internals back in.

All things considered, I feel the best solution is to live with it.

A "tiny nick" might even be harder to fix as you'd still need to sand, fill and refinish all in a very small area.

replace the device

Extra case is not usually a good idea. Heat escapes through the back vent, the bottom, the keyboard and many of the cases block that venting. A "sleeve" to protect while transporting makes sense, though.

If you are like me, you will be trading in when the system is too old to be considered anything but "parts". Small dents will be irrelevant.

Take better care in the future, return the "hard case" in favor of a traveling sleeve.
