Either try to box them or use the biohazard method:
Boxing:

Spoiler:

• Fill a cardboard box with dry ice the same weight as what you're supposed to be sending
  
• Close and tape up the cardboard box
  
• Kick the box around a bit, make it look like it's been beaten up. Cut the tape and retape it with a different type of tape
  
• Send it, they should think it's been stolen during transit
  

Biohazard:

Spoiler:

• Think of an excuse in which you could have gotten blood on the product (e.g cut yourself and blood dripped on the laptop or something, don't use that excuse though, think of something plausible)
  
• Tell them you tried to ship it back but you can't because of the blood
  
• If they ask for photo proof, photoshop your new laptop or a picture of somebody elses to have blood on it and send them that (photoshoping your new one may be slightly risky)
  

The Biohazard method is probably easier although the box method will probably have a higher success rate.

Thanks dude. I wonder what will happen if i dont send the "broken" one back
