Would Apple replace my chipped trackpad?

That is not covered by Apple's warranty as it is accidental damage. People have got away with worse however.

 

Warranty specifically excludes damage from accidents. It only covers manufacturing defects.

 

1) You would get better responses if you posted this in the perrifels section, not the iMac
2) being under warranty is not relevant you dropped it!!! The warranty covers manufacturing defects only
3) It is possible they may swap it but unlikely.
4) maybe if it stopped working the would replace it but it is still working for peets sake!

Thats like going to a car dealership and asking them to give you a new car after you crashed it.

 

Probably not, but you can always try. Drop by the Apple Store and ask a Genius, then report back here

 

Does that affect the performance of the device? No.

Will Apple replace a device that that is functionally sound? No.
