MacBook Air logic board components identification

I'm working on a macbook air a1304 logic board which has been liquid damaged. It gennerally looks fine, except from two tantalum capacitors marked with s7 Aw. and the component marked with white tape and text hdd com on some images and 4.7 UH 0815K on the actual chip. This looks like it has overheated.

Any suggestions to how i get and replace these? can't seem to find any info on these on the internet. Searched for an hour now :-(

Thanks

anderskiel the logic board is a 820-2375. This answer is not to diagnose your board error etc. just to identify the components.

Reference designator L7900 is a 4.7uH 7.5A IHLP4040CZ inductor

Reference designator C7930 is a 47UF 10V 20% Poly-Tant capacitor in a Case-B2 package.

Parts should be available at places like Digikey.com or mouser. com and will require some soldering to replace.
