Optical drive

[IsiahSheffield]

I do not know how to open the dvd tray on the HP all-in-one desk top computer. I pressed it but pressing it is not opening the tray. How do I open the tray?

All CD/DVDs have a TINY pin hole to eject disc.  Use a paper clip, push it in the hole.  You have to push quite a bit to eject it.

There is normally a button on the tray cover.  It can be small and very hard to see, but it is there.  You press that button to have the drive pop open.

If that does not work, then you open File Manager, look for the CD/.DVD device, right-click it and select Eject.
