Solved Are all internal laptop optical drives the same size?

Hewlett-packard / Dc7900

Specs: Windows 8.1, Intel e5200 dual/2gb
I would like to replace the DVD optical drive in my HP Compaq dc7900 Ultra-slim Desktop PC with a Blu Ray drive. Not yet decided whether that will be a full burner or just a BD ROM with DVD burner. My question is whether all internal laptop optical drives are the same size?

Would either work or do I need a specific model?

Many thanks

As far as I am aware they can vary between laptops, so your safest bet is to go to HP.
However you might get away with taking measurements and comparing that with whatever data is given.

It could be worth grabbing the HP number then googling for less expensive equivalents.

Always pop back and let us know the outcome - thanks

They often vary in thickness; more recent drives being slimmer/thiner than earlier drives.

Actual shape may also vary depending on make and model of the drive; as may the fixing points (the places where screws may be required to hold the unit in place). Some drives may be all in one; enclosed in a mounting case/frame, so not quite so, and you use the frame from the original drive (if it will fit/accommodate).Some may require you provide the bezel (the front plate) from the original drive, so not...

Many a given model drive may fit more than one brand of laptop; but always wise to check...

As Derek suggests, first check with hp, then maybe hunt on Amazon, possibly Egghead (if in USA/Canada); even eBay; as prices can/do vary. And if possible secure an option to return a replacement unit if it won't fit?

Many thanks to you both. Seems mean having to pick a best answer as both equally helpful to me.
