How can I open the base of HP envy 27-b100la there's no screws in the middle plate

[MariArg]

I want to clean the dust in the PC, there is no video for this PC with out middle plate screws. I already took off 4 black screws and 2 gray ones, it's a all in one computer 🖥️

@MariArg -- there is no video for this PC ...

Do you mean that your computer is NOT producing any video-output onto your screen, or that you cannot find a video-recording either on HP's web-site or the YouTube web-site on how to disassemble your All-In-One?

Got any "computerphile" friend who can help you with partial disassembly, and usage of part of a can of compressed air?  Or, pay a professional computer technician.

yes, the second one, I cannot find a video-recording either on HP's web-site and the YouTube web-site on how to disassemble my All-In-One.

I have the air compresed can, and I'am the one who do the disassembly of the computers (mine or my relatives PC), but i couldn't disassembly this one and there are no experienced technicians in the area.

What about: OPEN ME UP! HP Envy 27 - YouTube

???

No that one it's very diferent. There is one that is similar but it has screws in the center, but in my case those do not exist and I have already removed all the screws, I do not want to force disassembly since I am not sure I can remove it without breaking any part.

Watch the video for the amount of "leverage" and "force" that is used to remove the back-panel.

Or, take the computer to qualified computer technicians, and pay them do the work.
