Bas$ically it’s hard to show but it’s star-shaped, and the size is T10. HP 8610, 8620, 8615, 20 20 30 and 25 they’re pretty much the same and they have same removal process.

8600 series and 8600 plus are similar, and will also have the same build on the inside if you want to replace the power supply, or the logic board.

So what we’re gonna do is, you can see on the front here, if you open this cartridge door there’s one screw that we’re gonna remove here but we’re gonna do a blast there’s two screws on the back that were first gonna remove.

And the screws are located in these two areas there’s one here and one here and this is the panel that we need to remove in order to get access to the power supply. So we’re gonna remove these two board, the screws here.

Two are removed and the reason why we want to do this site last is we’re gonna use it as something that will pop the panel open. So we’re gonna unscrew it and keep the screw in here, and we’re gonna use it to push the panel out, and that’s what it does.

You push it with the screw push it out and it’s a simple removal. There’s gonna put the screw out so we don’t lose it. So we have a logic board here, and a power supply there.
