If it was working then it is possibly a spare from the power supply for a different mother board.

P4, P5 and P6 cables are unconnected. Where do they connect

Not necessarily. Most computers have extra power connector for modifications and expansions.

How to remove and replace dvd rom and dvd rewrite in hp m9300t

1) Computer off, computer unplugged from power, open the computer case,

FOLLOW Anti-Static Precautions:

2) Anti-Static Precautions:
Your body carries Static electricity. Static WILL fry out (Short Circuit) the delicate hardware components inside a computer.

Computer on a table, computer unplugged from power, computer case open.
TOUCH an unpainted surface, of the metal frame of the open computer case.
This action will relieve your body of Static.

Should you leave your computer in the middle of working on it, be SURE to Touch the metal frame again upon your return.

3) Remove the Front Cover,

4) Removing and replacing a CD/DVD drive,

The HP Pavilion Elite M9300t Desktop PC, is supposed to come with a SATA type of DVD R/W optical drive, and a SATA type of DVD drive, (Unless you have Bluetooth types of optical drives, of course),

This means they use a SATA power cable,

Note the L-shaped opening. Lines up with the L-shape on the optical drive power connector.

Note that there may be a small lock tab on top, that you depress on the SATA power cable's connector, in order to remove it from the optical drive.
(Some SATA cable connectors have it, some do not. Referring to power cable, and data cable)

The SATA power cable has 15 contact pins. Between it, and the SATA data cable, it has the longer connector.

This is a general example of a SATA data cable's connector.
7 contact pins,

(Top photo)
Here you can see the L-shaped opening more clearly.

When you are finished make SURE all cables are connected in tightly, on the inside of the computer. Sometimes when replacing hardware they get bumped loose.

Also make sure the Ram Memory module/s ('Stick'), are plugged in tightly. They also get bumped. Doesn't hurt to push down on them/it in the ram memory slot. Also make sure the Locks on each end of the Ram Memory module is locked in towards the Ram Memory module.

When the Locks are engaged, the Ram Memory module is properly seated.

P35-611 shuts down while plugged in but not while on battery

using a multi-purpose duster spray can seems to have solved this for me. i dusted the keyboard and a few other areas(carefully) with a q-tip. i wasn't able to fully open my laptop but i sprayed and q-tipped a little on the inside(i couldn't get to the fan which supposedly gathers the most dust) and when i feel the computer getting too warm,i'll spray the keyboard and the back of the computer and my computer ,which was shutting down **** near constantly, hasn't spontaneously shut down since,and i took out the battery. if your problem is dust,this might be at least a partial solution. if you need to take your laptop apart,there are videos on youtube,although like i say i wasn't able to take my p35-s611 all the way apart without possibly damaging the machine.

I want to install a CD/DVD RW drive. This is in addition to the installed CD/DVD already in place. The new drive has a SATA connection on the back, and the only available connector is an IDE connector....

There are IDE to SATA adapters and cables, such as this one linked below. IDE to SATA Adapter
You would simply plug this adapter into the available IDE connection on your motherboard, then use the SATA data and power cable to connect from the adapter to the CD/DVD drive. You can look around online for similar products, but they should get the job done!
