Replaced burnt out Power Supply Unit but don't remember which connector goes where. Unfortunately I didn't take note of it when I took the old power supply out. Any help?
Not a problem, Dawn.

Scroll down to the motherboard illustration, and motherboard photo under it.
A) 24-pin ATX main power cable:
Illustration:
Look to the right of the Ram Memory slots, DIMM 1 and DIMM 2.
Look at the rectangle with ATXPWR1
Scroll down a little to the motherboard photo.
To the right of the black Ram Memory slots, with the white Locks on each end, is the 24-pin ATX main power cable connector on the motherboard.
Whitish connector with 24 socket holes. Two columns of 10 socket holes.
This is an example of an average 24-pin ATX main power cable, and it's respective connector on the motherboard,
http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24
[Note* Color of connectors does NOT matter ]
Note the power cable connector in the middle photo, and the photo to the far right with the power cable plugged into the motherboard.
Note the Lock on the side.
The Lock has a hooked end that goes over a tab, on the motherboard's connector.
The Lock operates like a see-saw on a playground.
Squeeze the top of the Lock in, to bring the hooked end away from the tab on the motherboard connector, when removing the power cable.
When the power cable is plugged into the motherboard correctly, and properly, the Lock will be locked over the tab.
B) 4-pin ATX +12 Volt power cable:
Illustration:
The Processor socket is represented by LGA775.
To the left of it is ATX12V
In the motherboard photo it is the square whitish 4-socket hole connector, to the bottom left corner of the Processor socket.
This is a general example of a 4-pin ATX +12 Volt power cable, and it's respective connector on the motherboard,
http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4
Note that it has a Lock also.
That's it for power cables that plug into the motherboard.
Product specifications specifies that the harddrive is a SATA unit.
It uses a SATA power cable from the Power Supply,
http://www.playtool.com/pages/psuconnectors/connectors.html#sata
Note that a SATA power cable's connector has 15-pins, and has the longer connector when compared to the SATA data cable.
The SATA data cable's connector has 7-pins.
Example of a SATA data cable, it's connector, and matching connector on the motherboard,
http://en.wikipedia.org/wiki/File:SATA_ports.jpg
Note the SATA data cable connector, and it's matching connector on the motherboard have an L-shape key.
So does the SATA power cable, and whatever it plugs into.
(Harddrive / Optical Drive )
This is an example of a 4-pin standard Peripheral power cable.
Has been misnomered as a 'Molex' power cable,
http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral
IF, your SATA harddrive has a provision for a SATA power cable, AND a 4-pin Peripheral power cable, ONLY use just the SATA power cable.
Using both will burn up the SATA harddrive.
(Maybe not right away, but I assure you it WILL happen)
Do not use just a 4-pin Peripheral power cable on a SATA harddrive.
NOT enough power.
The Optical drive (DVD burner) is not stated whether it is a SATA unit, or IDE. (PATA)
If it is an IDE (PATA( unit it will use a 4-pin Peripheral power cable
It will also use a 40-pin flat ribbon data cable,
http://en.wikipedia.org/wiki/Parallel_ATA
http://en.wikipedia.org/wiki/File:PATA-cable.jpg
[May be 39 holes with 1 hole blocked off ]
CPU_FAN on the motherboard up above, and to the right of the Ram Memory slots, is where the Processor fan plugs into.
SYS_FAN below the processor socket, and to the right of ATX12V connector on motherboard, is for a computer case fan.
A computer case fan can also use a 4-pin standard Peripheral power cable, with an adapter cable, or may use a 4-pin small Peripheral power cable,
http://www.playtool.com/pages/psuconnectors/connectors.html#floppy
This power cable is also used for a Floppy Drive, and for newer computers is used on a Card Reader.

i had the same problem, i called hp and there is a recall on the mother board they will fix it for free, they did mine.

hi,
Might be the issue with display panel cable as well so please first try to refix it.
SOURCE: ''My HP Pavillion ZE5300 Laptop Doensn't Come On At All!''=v.v=
when you press the power button, does any light flash for 1 second?
remove the memory, hard disk, cd writer from the laptop. then try to switch on again. do it using the power adapter.
if it doesnt come on then its an internal problem. you will have to open the laptop case and remove all parts for test
good luck

Hi,
I think it would be better if you order the bottom base cover for the machine, because the bottom base cover have the power port connector installed with it and its connected to the Motherboard, the power port is not built-in to the Motherboard for the model of your machine.
Here are the Phone List of Lenovo.

SOURCE: My Asus Altec will not
There is no reset as such, however you can try the old trick of removing the battery and ac adaptor, pressing the power on button and holding for 30 seconds, then reconnecting the mains supply (not battery) and see if it will then boot.
If this fails, you need to check the following:
After that, the likelihood is that there is a fault on the board and will need more specialist investigation

Even though it's older the computer worked fine until the power supply went. Now that I replaced the power supply & I know it's hooked up right, well now the issue is that the monitor, keyboard, & mouse aren't connecting. I even tried my spare monitor/keyboard/mouse & still nothing.I'm wondering if when the power supply burnt out maybe it damaged something else, maybe something on the motherboard itself?

Dawn; Did you follow Anti-Static Precautions when replacing the motherboard? Did you clean the gold plated contact pins on the ram memory module/s ('Stick') with a pencil eraser? Replace the CMOS battery? Seem like I'm 'Clutching at straws'? Yes, and no. Trying to eliminate every possibility. A weak CR2032 battery will cause havoc. Ram memory that sits in a ram memory slot, develops 'corrosion' on the gold plated contact pins. Doesn't take much to make a bad contact.
Just out of curiousity also; Is there any bad Electrolytic Capacitors on the motherboard? Note Electrolytic. There are solid Polymer capacitors on the motherboard too. (One example of the solid Polymer's are the ones next to the Processor)http://www.capacitorlab.com/visible-fail... NOT advertising, just went looking;http://www.ebay.com/itm/HP-Compaq-5188-5...
Sorry it takes so long for me to respond. With my computer down I can only get top my brothers bout once a week to use his. Anyway I did take out the memory sticks & check them. I didn't clean them but they looked ok. I'll recheck them. I also took out the battery & put it back in but maybe I'll replace that too. I didn't replace the motherboard. I'm leavin that as a last resort. I'll check the capacitors also when I get home.
Thanks again for all your help!
Cleaning the contact pins of the Ram Memory modules; Use a pencil eraser. If you are using the eraser on the end of a pencil, and not a solid eraser, refrain from letting the metal band of the pencil touch the gold plated contact pins. Handle the Ram Memory module by the BODY. The Body is everywhere on the ram memory module, except the gold plated contact pins on the bottom,http://en.wikipedia.org/wiki/File:Generi... Rub up, and down on EACH contact pin. Both sides. Doesn't take much pressure, nor rubbing, to clean a contact pin. In fact when you are done they may not be bright, and shiny. You have cleaned them though, I assure you. Use air to remove the eraser dust. If you have a can of compressed air nearby, use it. If not air pressure from your mouth will be sufficient. Also do not assume a new Power Supply is OK. May have gotten a bad one. Weak voltage power rail. Definitely watch out over a used one, unless you saw it power up a computer OK. I'll be right here every week if needed.
Did everything you said, checked all the capacitors & cleaned the contact pins & the computer is connecting just fine now! I'm usuing it right now. Thank you Joe for all your help!!! No one I spoke to offline knew why it wasn't working. You saved me the expense of having to take it to a repair shop.
You are Most Kind! I just get lucky I guess, ha! (That and I'm a computer tech with years of knowledge)
