Hi pudelgrl, Thanks for your post. Adding additional parts to your computer will not void the warranty.  Just keep in mind that if you wish to troubleshoot with Dell's Tech Support, the unit will have to be returned to the original configuration. Regards,Robert
I'm setting up a law office and it has been suggested that I add an additional hard drive into my Dell computer that will automatically perform a daily backup. One thing that is not clear to me is how installing an additional hard drive would affect the warranty, so I thought I would ask my question directly: If I install my own additional hard drive, not purchased from dell, and assuming no damage occurs during the installation, does that void any part of the warranty? I do not need warranty coverage on the additional hard drive, I simply do not want to void any warranty on the existing hardware.
Warranty - will it be affected if I add another hard drive?
