Remove any non-original parts before shipping the system for service.  
so the day I got my laptop in the mail I took it to best buy to use a gift card and had them upgrade my hard drive, add a second hard drive and upgrade the ram to 16gig. if I have to send my laptop in for service do I remove my upgrades or do I leave everything in it? I don't have the original parts I gave them to a co worker.
Depot service, remove added hardware first?
