You need to lay your pc down flat and take off the side. Once you do that be sure to touch the casing to ground yourself and start unplugging all the power leads from your cd/dvd drive(s), harddrive(s), etc..
Once you have all the leads unlugged there should be 4 screws on the back of your PC holding the power supply. Take those out and carefully pull the power supply out from the side that is opened.

Think I should read the dates on the posts before i reply, lol:P Oh well maybe it'll help someone else:)

You're going to have to go, where no man has gone before


No not that bad just kidding.


Your body carries Static electricity.
An All-In-One desktop computer is set up like a laptop.

Once you remove the outside covers, the Static sensitive hardware components inside, are exposed.
You CANNOT just touch any metal frame, as you would for a regular desktop computer, and relieve your body of Static.

This means you need to wear an ESD wrist strap, and have it's alligator clip attached to a good ground source.

This is an example of an ESD wrist strap,

I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.
(I feel an Anti-Static mat is unwarranted)

You can set a large metal serving tray (Unpainted), on the table you're working on, and connect to it.
Or perhaps a large metal knickknack (Unpainted)

Just from a quick search for the Power Button Board and cable,

(The Power On Button assembly presses against the Power On switch.
The Power On switch is what should be bad. Of course you will know once you get to it.
The Power On switch is part of the above assembly)

I need to dismantle the HP IQ770 to get at the 3.5mm headphone socket on the front - I have opened the casing and can remove power supply, HDD and DVD Drive but no obvious way to get any further without...


I too needed to get to the jack. We broke the tip off inside. I could not get to the jack, but I did find the plug for the front jack on the board. Unplugged it and the speakers worked fine, and the headphone worked off of the rear speaker jack (green).
