HP Compaq nx7300. Pin has broken off from the power cord supply. Mains input cord now won't work as part of pin is possibly stuck inside. Took to original supplier who quoted £220 to replace entire motherboard and power supply. This can't be only option?

Absoloutly not!!!!! if the pin has broken in the external power cord and not inside the PC itself then all you have to do is replace the PSU ( power supply unit ) and the lead, this should cost you no more than £35 and its easy to replace yourself

When I turn it on monitor reads vga no input and the power is on, the fan is still running.


Bad Power Supply. Weak voltage power rail.

Has enough power to light LED lights, and maybe spin fans, but not enough to turn the Processor on.

1) ALL of the LED lights on at once use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts.

3) A typical Processor uses 51 to 125 Watts. Depends on what Processor it is.

The Compaq Presario SR2013WM desktop computer, comes with an AMD Athlon 64 3800+ processor, that fits in a Socket AM2.

1) http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00777760&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&lang=en&product=3300335


Can use up to 62 Watts.

2) http://en.wikipedia.org/wiki/List_of_AMD_Athlon_64_microprocessors#.22Orleans.22_.28F2_.26_F3.2C_90_nm.29

No Processor operating, no computer.
No computer operating, No Signal to the monitor. (No video signal, or also known as No VGA Signal)

The Power Supply used is just one of the common ATX form factor power supply's.
Used in over 80 percent of PC's out there, and readily available.
(ATX size of the power supply case, is approximately 5-1/2 inches Long, 3-1/2 inches Tall, and 6 inches Wide)

It is 250 Watt, and a generic model. Probably made by Bestec, Delta, or HiPro.
(You can use a larger wattage Power Supply with NO problems.
A computer ONLY uses the power it needs, and NO more)

A) The ATX main power cable is a 24-pin ATX main power cable. All of the new power supply's have an ATX main power cable, where the connector can be used as a 20-pin, or 24-pin.

B) Uses a 4-pin ATX +12 Volt power cable.

C) Past the two power cables above, just make sure the Power Supply has a SATA power cable, (For the SATA harddrive), a Floppy Drive power cable, (Used for the Card Reader), and enough 4-pin standard Peripheral power cables.
(Misnomered as 'Molex')


3) Typical 24-pin ATX main power cable,

4) Typical 4-pin ATX +12 Volt power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

5) Typical SATA power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

IF, the SATA harddrive has a provision for using a 4-pin standard Peripheral power cable, AND a SATA power cable, ONLY USE THE SATA POWER CABLE.

If you use both you will burn up the SATA harddrive.


6) Typical 4-pin standard Peripheral power cable,

How do I replace a power supply on a Compaq Presario SR5110NX Desktop PC


you can purchase a power supply from any computer store *********** board supports both standard IDE and Serial ATA connections, so you want a power supply that does SATA power as well. Unplug the power cord from the back of the computer. remove the cover from the case and verify that there is no green LED on the board that is lit up (if there is, there is still power on the board). unplug all connections from the current power supply, including all drive power and the large 24pin plug (actually a 4 pin plug that is combined with a 20 pin plug) on the board, then unplug the 4 pin plug near the processor. careful that the 24 pin plug and the additional 4 pin plug near the processor have latches on the side. Remove the 4 screws that hold the power supply in and remove the power supply, install new supply and reinstall the 4 screws. first plug in the 4 pin plug that connects with the 20 pin, the 4 pin plug has no latch, it is held in place by the 20 pin plug. then plug in the 20 pin plug and the 4 pin next to the processor. then plug in the drive power to all of the drives. Install the power plug at the back of the system and you should see a green LED on the board when you insert the power. replace the cover and power the system up.

Not sure about upgrading power supply


In many cases the additional 4 pin section slides up and off of the main power plug for use in your particular unit.

Might be stuck in hibernation. Pull the battery and ac power for about 1 hour. Replace and try to boot. If fails, pull the battery and try to boot just off ac power.

Psu blinking green light, no power


I read all the solutions, followed the manufacturers instructions exactly, replaced the cmos battery and nothing solved the problem (blinking light on PSU after a power failure and no startup at all). I had ascertained that the PSU was intact by disconnecting all the PSU connections to drives and motherboard at which time the PSU LED stopped blinking and was constantly on.
Just before throwing my computer away I decided to follow the instructions listed by "guest" to unplug the power to the motherboard and then with the power supply back on to plug the cables back into the motherboard. No only did sparks not fly, but it started up and ran perfectly! Many thanks to "guest."

No power


1. Please check with the power supply of pc from a/c plug. 2. if power supply is ok then ensure that the input poewer cord is at right position in behind of cpu. 3. If you are using old type power supply (which do not autumatically turned off by operating system) then there is problem with power switch or SMPS. 4. If you are using advance power management (generally used in now-a days computers which is automatically turned off by O.S., then there may be a problem with power pin that is connecting thae mother board and power button. Shut down your computer and open the cpu chasis and tighten the pin and ensure that it is properly inserted (the location of the pin is near hard disk lid pin, power lid pin). 5. If this pin is ok then check with pconnecting wire of pin and power button and also the power button. 6.Then turn the computer on. If it does not work then check the power connectors from SMPS to mother board are properly installed and inserted. 7. If power connector is ok then there is posssiblity of problem with your SMPS (power supply) of computer. 8.Generally due to heavy load of power and long usage the condensers of smps get mailfunctioned. Take the smps or computer to a local hardware expert.
