Question about Dell Inspiron 531s Desktop Computer
Hmmm, P4 is usually a designation, for a 4-pin ATX +12 Volt power cable,
I see though that they have P2 as the 4-pin ATX +12 Volt power cable, and P4 as a SMALL 4-pin Peripheral power cable,
This type of power cable is used on a Floppy Drive, or a Card Reader.
Not a Harddrive, or Optical Drive. (CD/DVD drive)
The Standard 4-pin Peripheral power cable, is used on an IDE (PATA) harddrive, or optical drive,
Rounder corners on the Top of the plug connector.
Only plugs in, in one direction.
Owner's Manual > Page 109 -
Power Supply DC Connector Pin Assignments
P1 = 24-pin ATX main power cable,
P2 shown above - 4-pin ATX +12 Volt power cable
P3, P5, and P6 are SATA power cables,
If you have a SATA optical drive (CD/DVD drive), the above is the power cable used.
Uses a SATA data cable,
SATA data cable connector on motherboard, is shown below the SATA data cable.
Color does NOT matter

Unplug the power cable from your power supply and open up your computer Don't forget to wear your antistatic wrist band. Determine which drive bay you are going to install a CD-ROM into. You should pick on of the uppermost drive bays. Before you install a CD-ROM, make sure you have the proper jumper settings. Since we are only installing a single CD-ROM, set the jumpers as MASTER. The jumper settings are different for each CD-ROM drive, so consult your owner's manual so you know which pins to cover up. Once you have the jumpers set, install your CD-ROM in the computer's case. How you secure the CD-ROM in one of the uppermost drive bays depends on your case. Some CD-ROM drives have to be screwed into the drive bay, while other cases come with brackets (like mine) to attach to the CD-ROM drive so that it slides into the drive bay and locks in place.
Connect the power to the back of the CD-ROM drive, then connect the ribbon cable to the back of the CD-ROM drive. Your ribbon cable has three connectors, one in the middle and one on each end. The middle connector is a "SLAVE" connector that is used if you would install an additional CD-ROM or DVD-ROM drive.
Connect one of the end connectors to the CD-ROM drive, and connect the other end connector to the appropriate spot on your motherboard. Note, hard drives and CD-ROM drives have the same style of connector on the motherboard. You want to connect your CD-ROM drive to the motherboard slot that isn't red or is the highest numbered of all the IDE slots.
Power on your computer after you plug it in. Your computer should recognize the new CD-ROM. If it doesn't, Click start control panel administrive tools,computer management,device manager scroll down cd-dvd rom drives you might see a yellow question mark ? right click to update driver,roll back driver,or select properties general troubleshoot, select driver click to reinstall drivers click update driver
Hope this helps
