The HP Pavilion DV4 Series MultiBay: Weight Saver, Optical Drive, Hard Drive

[ Edited ]

This is a guide for the HP Pavilion DV4 Series of notebooks.


The expansion bay is an HP MultiBay, which means you can use it for multiple purposes:

  • Hard Drive
  • Optical Drive (CD/DVD/BluRay)
  • Nothing (Dummy Slot Cover)

HP MultiBay Hard Drive Kit

If you'd like to install a second hard drive, you'll need to order the Multibay Hard Disk Drive Hardware Kit.  You can purchase it here from HP for $74.10 USD.  You might also check using the Product Number (PN) from the tag beneath your notebook in the event that there's a different part available/needed.  The kit does not include a hard drive, so you'll need to purchase it seperately.  You'll need a standard 2.5 inch SATA hard drive of your liking. (here)


Notes about using a hard drive in the HP MultiBay:

  • Hot Plug and Play (Needs to be safely ejected through Windows)
  • HP ProtectSmart also works with the MultiBay.





The HP MultiBay Weight Saver ships with most of the DV4 notebooks, and can be used in place of a drive to reduce the weight of the notebook. If you've lost yours, you can order a replacement through the HP Parts Store.  You can order the standard cover here, or if you need a color-matched cover (bronze, onyx, etc) then you'll need to search using
