Replace power jack

Power supply failures in a HP computer can cause your computer to fail to turn on, to operate erratically or cause certain system components not function.

However, the power supply is one of the easiest parts of a computer to replace.
You don't need any special skills to do this.

If you're nervous about opening up your computer case and potentially damaging a computer component, don't be.

All you are really doing is plugging in power supply cables after securing the power supply.
The process should take 10 minutes maximum.

Shut down your HP computer.
Disconnect the power cable from the power supply on the back of your computer.

WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. - rules
Only work inside the computer case when the power has been switched off and disconnected. Never open the power source.

Some of the below steps recommend removing physical parts within the computer.
While in the computer it is highly recommend that you be aware of ESD and its potential hazards.

Unscrew the side panel from the back of the case and slide it off.
Newer HP computers may have a case door you can open for access or have access buttons to press.

Look at the back of your HP computer case for a set of four screws near the top of the case. Remove these screws and set them aside.
Carefully slide your power supply out of the mounting brackets and set it on a clean working surface.
Do not disconnect any of the power connectors yet.

Slide your replacement HP power supply into the case and use the mounting screws to attach it to the chassis.

Use your old HP power supply as a guide to connect your new power supply to all the computer components.

Switch the power cables from each device from the old supply to the new supply so you don't miss connecting any cables.

Check that all the components have power cables inserted and the old HP power supply is completely disconnected from the system.

Close the HP computer case and plug the power cable into the new HP power supply.

Will this graphics card work with my computer?

1) HP xw6200 Workstation desktop computer,

Power Supply: Maximum rated Wattage - 500 Watts.

XFX ATI Radeon HD5750 graphics card,


1) Install the software F-I-R-S-T, then physically install the graphics card.
Windows running, put the Installation disk that comes with the graphics card, into the CD/DVD drive.
Load all software. The drivers, and Catalyst Control Panel.

Windows will NOT use the software until the graphics card is installed, so don't worry about not having graphics in the meantime.

2) Computer unplugged from power FOLLOW Anti-Static Precautions.

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

Relieve your body of Static BEFORE reaching inside your computer, AND before removing any parts out of their anti-static bags, or cartons.

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.

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

3) Physically install the graphics card.
(The Lock Lever on the PCI-Express x16 slot, goes UP to install a graphics card, or to remove a graphics card. It looks as though you should push down on it)

Looking at the black PCI-Express x16 slot, with it's green Lock Lever, it looks as though there should be room for the graphics card.

Looking to the right of the green Lock Lever, look at the 4 gold colored Choke Coils. It may be tight, but the graphics card should clear the first two.

Areas of concern, though;

1) Power Supply:
The XFX Radeon HD5750 graphics card, requires a minimum of a 400 Watt Power Supply.

The graphics card doesn't use 400 Watts, of course. This is the minimum power requirement by the graphics card manufacturer, and based on the power the card needs, and the rest of the computer.

XFX, just like all graphics card manufacturers, uses a computer system set up to the maximum, for a test unit.

Gamer style motherboard.
Powerful Processor, that is probably a dual core, or quad core.
Maximum amount of ram memory.
Two optical drives
Two or more computer case fans.
Two or more harddrives.

You get the picture.

Power consumption has to be based upon what each individual hardware component will use, AND the graphics card.

Power Supply:
Problem is, the computer has some age on it. From searching it seems to have been made in 2004. Makes it 8 years old now.
Makes that Power Supply 8 years old now too.

A) Pre-built computer manufacturers, such as HP, Gateway, Lenovo, Toshiba, etc., have their components made by someone else.
The Power Supply is one such component.

Usually a generic Power Supply manufacturer, such as Bestec, or HiPro, or Delta, for HP computers.
Low quality electronic components are used in these power supply's.

Isn't a big deal usually, until you start to tax the limit on the Power Supply, such as installing a powerful graphics card.

Power Supply manufacturers also had a great tendency, to overate their Power Supply's back in the day. Made the Power Supply sell better, 'fudging' the actual Wattage rating.

Wattage was actually more like 60 to 70 percent, of what was stated.
300 Watts (60 percent) to 350 Watts (70 percent) is more actual.

The XFX ATI Radeon HD5750 also requires a 6-pin PCI-Express power cable, coming from the Power Supply, and connected to it.

The maximum amount of Wattage a PCI-Express x16 slot can deliver, is 75 Watts.
The 6-pin PCI-Express power cable delivers an additional 75 Watts,

"This cable is used to provide extra 12 volt power to PCI Express expansion cards.
PCI Express motherboard slots can provide a maximum of 75 watts.

Many video cards draw significantly more than 75 watts, so the 6 pin PCI Express power cable was created.
These high-power cards draw most of their power from the 12 volt rail so this cable provides only 12 volts."

(Yellow wires are 12 Volt wires. Red wires are 5 Volt wires, Orange wires are 3.3 Volts. All are DC voltage. Black wires are Ground wires)

Will your Power Supply have a 6-pin PCI-Express power cable?
I doubt it.
In the Playtool link, see the 6-pin PCI-Express adapter power cable, shown on the right?

Takes TWO 4-pin Peripheral power cables,
(Commonly misnomered as a 'Molex' power cable),

If you are going to use one of these power adapter cables, you NEED TWO 4-pin Peripheral power cables!

HAS to have TWO Yellow 12 Volt wires going to it.

Will using a 6-pin PCI-Express adapter power cable, and One 4-pin Peripheral power cable work?
Most of the time yes.

Over time the;

1) PCI-Express x16 slot contact pins -> BURN

2) Gold plated contact pins on the bottom of the graphics card -> BURNS

3) Connection on graphics card for the 6-pin PCI-Express power cable - BURNS

4) 6-pin PCI-Express power cable's connector -> BURNS

No if's, and's, or but's; it WILL happen.
Result is usually throw the motherboard away, and the graphics card.

So you may be looking at getting a better Power Supply.
Here is one example that will work,

A) 600 Watts. Gives you an additional 100 Watts of power. Less strain on the Power Supply.

B) 120mm fan. A larger fan turns slower, therefore makes less noise.
Puts out more air flow than an 80mm fan, even though it turns slower.

C) Has all the power cables required, plus more.

D) Has TWO 12 Volt power rails.
12 Volt 1 is capable of 23 Amp's.
12 Volt 2 is capable of 20 Amp's.
Total combined Amperage for the two 12 volt power rails is 43 Amp's.

Gamer computer?
Not IMHO. Uses ECC ram memory.

That is Error Correcting Control ram memory. The ram memory runs the data through it twice, in order to make sure everything is correct, before using the data.
This is the type of ram memory a Server computer uses.

Could be wrong, and it could be used as a gamer computer, though. We will see when you are done, IF this is the intent.


Reasons for not using ECC:
"A performance decrease of around 2-3 percent, depending on application, due to the additional time needed for ECC memory controllers to perform error checking;"

1 Answer

It wont turn on when its plugged in

Pertaining to a Compaq Presario SR1500NX Desktop PC;

Let's see if the problem is a $5 ATX Power On switch, or the Power Supply.

Use a jumper wire on the 20-pin ATX main power cable.
Bypass the Power On switch.

IF, the Power Supply comes on you have a bad Power On switch.
IF, the Power Supply does Not come on you have a bad Power Supply.

This is a look at your motherboard with no hardware components installed, and no cables,

Scroll the page down to the illustration, and photo of the motherboard.

Looking at the illustration look at the Right/Middle.
The ATX Power Connector, is the female connector on the motherboard, that the 20-pin ATX main power cable plugs into.

Match that up to the photo. Whitish long connector, with two columns of 10 socket holes.

This is a general example of a 20-pin ATX main power cable, and it's respective connector on the motherboard,

[NOTE* Color of the connectors NEVER matters ]

The photo to the right shows the 20-pin ATX main power cable, plugged into the motherboard. This is how it should be for the test. Also the Power Supply should be plugged into power.

Look at the Green wire, going into the Back of the power cable's connector.
This is the Soft Power On wire. Abbreviated as PS_ON.
This wire is briefly jumped to A-N-Y Black wire.
ALL Black wires are Ground wires.

The preferred jumper wire is a paper clip. The paper clip is straightened out, then bent into a U-shape.
The middle of the U is wrapped a few times, with black plastic electrical tape.
This area is for your fingers, and thumb to hold onto.

Turn the U upside down. The 'legs' of the U-shaped jumper wire, is what is used.
Look at the squarish socket hole for the Green wire, in the Back of the power cable's connector.
There is room for the 'leg' of the U-shaped jumper wire, to slide down in.

Slides RIGHT NEXT TO the Green wire.
Slides past the insulation of the green wire, and goes down in far enough, to touch a metal terminal.

Every wire going down into the connector, of the 20-pin ATX main power cable's connector, ends in a metal terminal.
Looks like this,
(Except the left side is crimped over, on the insulation of the wire),

The right side is what you barely see, in the middle photo on the Playtool link. The, what look to be almost black spots, (24 of 'em), are the ends of the metal terminals. (Right side)

For this reason you need to ensure the 'leg' of the jumper wire, is going down past the Green wire's insulation, and actually touching the metal terminal. Otherwise you have made no contact with the jumper wire, at all.

The other 'leg' of the U-shaped jumper wire, goes down into A-N-Y socket hole in the Back of the power cable's connector, that has a Black wire in it.

The contact made is no more than 2 seconds.
(The Power On switch is a Momentary Contact Switch)

Worried about Shock?
1) There may be a small spark. This is just the way electricity acts when you complete a circuit, and touching an open wire.

2) The Soft Power On circuit is 5 VOLTS DC.
In comparison two D cell flashlight batteries store 3 VOLTS DC.

For me? Shock is none, or minimal. YOU, may wish to wear a glove, on the hand that holds the U-shaped jumper wire.
Just want you to feel safe.

[Your Power Supply is an Inverter. It converts AC electricity from your home, or business, into low DC electricity.
120 or 220 Volts AC down to three low DC voltages;
A) 3.3 Volts
B) 5 Volts
C) 12 Volts
All are DC voltage.

{ Just like a line pole transformer steps down 7,200 Volts AC single phase, into 220 Volts single phase, for your home} ]

BEFORE reaching into your unplugged from power, computer, FOLLOW Anti-Static Precautions;

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.

{You are 1/10th less concerned about getting shocked, as you are about Static shocking your computer hardware parts }

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

Replace Power On switch:

The Power On button is a plastic assembly. Inside the assembly is just a regular ATX power on switch. The following example is used in a LOT of Desktop PC's,

The Front Panel of the computer is removed, to access the Power On button assembly.

BEFORE removing the Front Panel, make notes, and a drawing, as to where on the motherboard, ALL the wires go to from the Front Panel. This is in case you accidentally bump a wire loose }

The plastic of the Power On button assembly becomes brittle with age, and heat from the computer.

Once removed from the Front Panel, here are two methods I have used, to remove the Power On switch without breaking the plastic Power On button assembly;

1) The Power On switch has been deemed to be no good. Doesn't matter what happens to it from here on out.
I use a small bowl of VERY hot water, and dip the plastic Power On button assembly down into it, while holding onto the wires.

Once it is felt the plastic has softened, I ease back on one tab, at a time, and ease the Power on switch out.
You have to use finesse, and feel if the plastic is soft enough, before you start bending on any tabs.
If not, re-dip in the very warm water, until you feel it is.

2) Use a hair dryer, and heat the plastic up.

In both cases you are dealing with a very warm to hot plastic object, so use gloves, and caution.

[Want to buy the entire Power On button assembly? Sure.
A) If you can find one. If so from an 'auction', remember the Power On switch inside, is U-S-E-D. Who knows how long it will last?
Same if a local computer shop has one.

B) HP Parts? May have one. If so, can you say OUCH? $$ ]

Replace Power Supply:

The Power Supply is just a regular ATX style, and 250 Watt.
Approximate size is 6 inches Wide, 5-1/2 inches Long, and
3-1/2 inches Tall.

This is one example of a Power Supply that is reliable, and compatible,

120mm fan is larger, than the 80mm fan of your old Power Supply
Larger fan turns slower, but produces more air flow.
Turning slower also makes it quieter.
(Unless you are gaming at full throttle! But the game sounds will overshadow the fan noise! Lol! )

550 Watts. Means your computer won't strain for power.
(Note* A computer ONLY uses the power it needs, and NO more.
If it only needs 100 Watts, for example, when surfing the internet, it ONLY uses 100 Watts )

Has all the power cables you'll need, and more.
(Tie the extra power cables up out of the way with plastic ties.
If you need them in the future, you'll have them)

The ATX main power cable has a 20 + 4-pin connector.
Means it can be used as a 20-pin ATX main power cable, which you need; or a 24-pin ATX main power cable.

Want to test the Power Supply before buying a new one?
You need a multimeter. An inexpensive, but good enough for this test, multimeter, can be purchased for as little as $8 to $12.
Available in a multitude of stores. An auto parts store is but one example.

Post back with multimeter in hand, and I'll guide you.

My 1620n HP pavilion will not start. The push button will not light or start the computer. I tried different outlets and power cords just in case, but it will not power up. I presume it is the power supply...

larry_moo748 I'll tell you how to see if it's the Power Supply, or the Power On switch that is the problem.
(The Power On switch is located inside the plastic Power On button)

I would also like you to reconsider taking it to a computer repair shop, IF the problem is a bad Power Supply, and replacing the Power Supply yourself.
It isn't that hard, and it will save you money.

The test to diagnose whether the problem is the Power Supply, or Power On switch, involves bypassing the Power On switch.

A jumper wire is made from a paper clip straightened out, then bent into a U-shape. The middle of the U-shape is wrapped with a few turns of plastic electrical tape.
This is where you hold the jumper wire.

The voltage involved here Larry is 5 Volts DC.
Two D cell flashlight batteries produce 3 Volts DC.
However there may be a small spark.
Just want you to know what is involved.

Also,...your Power Supply is a voltage converter. It converts 120 Volts AC, (USA), or 220 Volts AC (Europe), to three main DC voltages.
1) 3.3 Volts
2) 5 Volts
3) 12 Volts

I would like you to look at your Pavilion a1620n motherboard on HP Support,

Looking at the motherboard photo at the top, observe the Ram Memory slots.
The long Blue, and Black slots to the right, with the White lock tabs on each end.

To the right of ram memory slot 4, (Black slot all the way to the right), is the 24-pin ATX main power cable connector, on the motherboard.
It is a White vertical connector (In this photo orientation), and has 24 socket holes.
Two columns of 12.

This is where the 24-pin ATX main power cable from the Power Supply plugs in.
Let's look at a closer view of a typical 24-pin ATX main power cable,

Observe the photo to the far Right. This shows a 24-pin ATX main power cable plugged into the motherboard.
Observe the Green wire, and look at the Black wires.
The Green wire is the Soft Power On wire. (Also abbreviated as PS_ON)
This is a 5 Volt DC wire.

Observe the Black wires.
ALL Black wires are Ground wires.

The jumper wire goes down into the socket hole with the Green wire, RIGHT NEXT to the Green wire.
At the end of the Green wire is a metal terminal. The jumper wire must go down into the socket hole far enough to Touch the metal terminal. (Approximately 1/2 inch)

The other end of the jumper wire goes down into a socket hole with ANY Black wire.
The jumper wire is a U-shape. Both ends of the jumper wire go down into the above named socket holes, at the same time.

The connection made is no more than 2 seconds.
Power Supply comes on? You have a bad Power On switch.
Power Supply does Not come on? You have a bad Power Supply.
(Should have added before, that the Power Supply is plugged into power for this test)

Disconnect all cables to the computer tower, except for the power cord. Open the computer case. Lay the computer on it's side, open side up, on a table. You can lay the computer on a towel to keep from scratching the table, and the computer case.
(Doesn't hurt the computer to run laying on it's side. You can run a computer upside down if you wish. Kinda' hard to put a disk in the optical drive, though! lol)

After you have achieved this test, and if you have found the Power Supply to be bad, post in a Comment if you wish step by step instructions (And a video, or two), of how to replace the Power Supply.
I will also recommend a few Power Supply choices if you wish.

[ It's an ATX power supply.

Install hard drive in hp a1310n

You need to do a number of things:

1) You need to carefully remove the door and the whole front face of the desktop (the front face opens like a door it swings open from left to right)

2) Once you have the front pannel open take a philips screwdriver and unscrew the memory card readers that is show in front of the deskop (there is one screw holding this card reader in place probably on the upper right hand corner.

3) Carefully remove the card reader by jiggiling it lightly till the unit comes off.

4) After you remove the card reader, you will immediatly see the hard drive directly behind the reader that you just removed.

5) Now look inside the desktop (because you removed the right hand side door: the big one that alows you to see inside the pc) and remove all cables from this hard drive before you read #6 below

6) Inside the desktop, Locate the hard drive, put your hand on the back of it and lift on the green plastic part along side the hard drive where you can see the harddrive screw which is on a metal track stopped by a green plastic stopper.

7) Lift the green plastic stopper and push the back of the hard drive to the front of the desktop.

8) Unscrew all screws from old hard drive and rescrew them on the new one in the exact same spots at the old hard drive.

9)Once you finish screwing on the screws, slide the new hard drive back from where the old one was

10) reconnect all data cables and power supply cable.

11) follow steps 7 thru 1 to put unit back together again. Go thru steps 7 thru one backwards

I hope this helps

My card reader on my computer has stopped working!? ok i took my computer in to my computer teacher to get it fixed, well she put in a second hard drive in and said it should fine. well it does but...

Ah, My Bad, big_dude2010, perfectly understandable about the budget thing. The world is in an economic crisis right now.

As for reattaching the Card Reader cable, can't help you.

OH, I'm just PLAYIN'!

Before we go ANY further:

1) Computer off, and unplugged from power.

Unplug the power cable FROM the surge protector, and NOT plugged into the surge protector, and take it out of the back of the Power Supply.

With the power cable plugged into the surge protector, and unplugging it out of the Power Supply, you could create a voltage spike.

Result can burn out the Power Supply, and may go on to burn out the Processor, Motherboard, Ram Memory, and a graphics card. (IF used)

Many have stated, that they do this all the time. Eventually, they come back to state they fried out their power supply, and/or motherboard, and so on.

2) Computer unplugged from power, computer case open, TOUCH the metal frame of the computer case to relieve your body of Static electricity.

Static can fry out, (Short Circuit), the delicate hardware components inside your computer.
(For this reason also work on a table. If you have a carpet floor, refrain from swinging your feet back, and forth.
If you get up, walk away, then return, TOUCH the metal frame again)

If you already know the above, please disregard.

The Card Reader cable has a white sheath, and is approximately as thick as a No.2 pencil.

It should have 8 wires in it.
Orange, Yellow, Blue, Brown, Red, White, Green, and Black.

It will have a white rectangular connector on one end, that has 10 socket holes. 2 rows of 5 holes.
Only 8 socket holes are used.

The other end of the cable should have a Black connector. It also has 10 socket holes. 2 rows of 5 holes. This connector plugs into the circuit board of the Card Reader.

The White connector end plugs into the motherboard. It plugs into the Front USB 1 header on the motherboard.

(Connector on a motherboard is referred to as a Header)

Orienting the motherboard, so we are both looking at it in the same direction.
Processor to the top. Ram Memory slots to the right.
There are 3 white PCI slots down towards the bottom.

The white PCI slot that is closest to the edge of the motherboard, is PCI3. (PCI 3)

Down below the PCI 3 slot is a blue header. NOT the one you want.
That's for the audio ports in the front of the computer. (Front Panel)

To the right of the blue header, is a white header. This is the one you want. Front USB1. (The Front USB1 header, is below the Right/Bottom corner of the PCI 3 slot)

Note that there are 5 pins going along the top of the Front USB 1 header, and 4 pins going along the bottom.

The missing pin, or blank spot, helps you to orient the white connector of the card reader cable.

The card reader cable's white connector also has a missing socket hole, or blank spot.

There is No slot on the header for the motherboard, and No locating lug on the Card Reader cable's, white connector.

Line the card reader cable connector's blank spot, up with the blank spot on the Front USB1 header.

This is HP Support, and the Motherboard Specifications page, for the Compaq Presario SR1303WM Desktop PC,

Scroll down the page about halfway, and you'll see an illustration of your motherboard.

(To enlarge it for better viewing, you can right-click right on it, then in the drop down menu, left-click on - Save As
Put this in your My Pictures folder.

Then go to My Pictures, and double-click on the illustration of the motherboard.
Now go below in the window, and click on the + sign to Zoom In.
Use the bottom, and side bar, to move it around to the view you want)

Below the illustration is an actual photograph of the motherboard, with no hardware components installed.

The Black connector that goes to the circuit board of the Card Reader, plugs in like this.

There are four wires across the top. There are five wires across the bottom.

Looking INSIDE your computer, TOWARDS the Card Reader circuit board, the four wires go on top, when plugged in. (Not shouting)

Again, looking at the back of the Card Reader, the color code of the wires on the top, going from Left to Right, are:
Thin Black wire, Green, White, and Red.

Wires going along the bottom, starting from Left going Right,
Thick Black wire, Brown, Blue, Yellow, and Orange
