Need to know how to quickly send back your Dell hardware to be repaired? You will need to contact Dell directly and tell them your situation. Verify your hardware is under warranty with your service tag.
They will most likely ship you out a box and return shipping label so that you can return your failing hardware into their depot service. Once they verify you have failing hardware, they will then ship you back new replacement hardware. You can check out this web page with Dell phone numbers for technical support information.
I recommend calling them at their #800 tech support line to get your hardware replaced as fast as possible.
