HP Pavillion pc doesn't boot up ... no fan, no start sound, nothi


Bad Power Supply.

The blinking green light on the power supply, is a diagnostic light that indicates this.

Suggestion is to;
1) Test the Power Supply voltages
Or
2) Replace the Power Supply with a Known to be good, Compatible unit, for a test.

[Compatible:

A) It is an ATX style of power supply.
The style used by 90 percent, of personal computers out there.

Example: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4975140&CatId=106

The test Power Supply unit should be mounted in the computer, for testing.
The power cables only reach so far, plus it is safer.

B) At least a 250 to 300 Watt unit, for a test unit. More Wattage is okay.

(The power supply that comes with the Pavilion a1310n, is a 300 Watt unit.

The 250 Watt unit stated above is just for a Test.
You are testing to see if the Power Supply is the problem.

More wattage is okay as a computer only uses what it needs.
If you have a 1000 Watt power supply installed, and the computer only needs 100 Watts; the computer only uses 100 watts.

The computer Will Not burn up, by installing a power supply with more Wattage than the original)

C) Correct amount of power cables, and correct kind.

Observe the power cables from the existing power supply, that are plugged into the various hardware components in the computer, and to the motherboard.

The test unit has to have the same power cables, and the correct amount of them.

Need help identifying these power cables, reply in a Comment.

The above may sound funny. Who has a spare power supply laying around, other than someone really committed to computers?

You may find yourself, or someone you may associate with, has a computer sitting in a closet, basement, attic or garage, that has a working power supply, (And is compatible), and can be used for a test unit.

Test the Voltages.

There are three main Voltages, produced by a personal computer power supply.
(DC. Direct Current)

1) 3.3 Volts (Wires that have Orange insulation)
2) 5 Volts (Red wires)
3) 12 Volts (Yellow wires)

(Two D cell flashlight batteries are 3 Volts {DC)

ANY Black wire is a Ground wire.

Use an economical multimeter to test the Voltages, or a power supply tester.

Multimeter:
Power Supply on.
Positive probe lead (Red) connects to the power wire to be tested.
Negative probe lead (Black) touches ANY Black wire.
(Black insulated wires are Ground wires)

This is one example of a power supply tester,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5250576&CatId=5471

What causes Power Supply failure?

A) Inside of computer is dirty, as well as the inside of the Power Supply.

Computer unplugged from power, (Computer case open, and anti-static precautions observed), a can of compressed air for computers is used on a regular basis as needed, to help prevent this.

There are two cooling components for a SMPS.
(Switched Mode Power Supply)

1) The internal fan
2) The Heatsink's inside

http://en.wikipedia.org/wiki/Switched-mode_power_supply

A Heatsink, is an object used to draw heat from whatever hardware component, it is placed against.

A Heatsink is generally just a flat, square piece of metal, that has tall, thin fins protruding from it.

The flat metal base absorbs heat, whereby it is absorbed by the tall thin fins, and radiated away.

In the case of a Power Supply, there is an internal fan which draws air in-between the fins, helping to carry the heat away.

Once the fan blades, (Plus center hub, and surrounding cage), become coated with gunk, and the Heatsink fins become coated, the cooling capacity drops tremendously.

Heat = Wasted Energy.
The Power Supply has to produce more power, to keep up with loss of energy.
Eventually hardware components inside the Power Supply fail.

B) Cheap quality components used in the power supply. (Cheap quality power supply)

Awaiting any question you may have regarding this.
Post in a Comment.

How can I test my Antec True 380sp is working properly


Would you like to do a full scale test or just see if it turns on?

Just to see if it turns on just hotwire it!
http://www.overclock.net/faqs/96712-how-jump-start-power-supply-psu.html

For a full scale test you need to buy one of these:
http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&Description=power%20supply%20tester&bop=And&ActiveSearchResult=True&Order=PRICE

Or if you have the patience you can use a multimeter.

Gateway yellow power button, nothing starts, no fan, nothing. opened up computer and see mobo led light is lit. newton ps has a test button. tried to test with various components plugged in and the test...


Power supply has several voltages. Just because the 5v power is active doesn't mean all the voltages are OK. You need to have the power supply tested for 12v and 3.3v. A quick test is to unplug all the wires from the power supply. There is a single green wire on the motherboard main plug. Connect (use a bent paper clip) that green switch wire and any black wire. Plug in the power supply and it should run (fan starts)

Computer does not turn on


you can try your power supply if it works by jumpering its pin. try to insert copper wire in pin 11 and connect it to pin 12. and turn o your power supply. But if it won't works then used tester and test its circuit boards particularly  is capacitors, resistors and even the transformer inside the power supply. Or if you can't make it then you can call a technician either in computer or electrical to test your power supply if it still working or not. In that wy can be sure in making decision if its really your power supply got problem or not.

E-machine Model D2246 does not power up


E-machines are notorious for having weak power supplies. Although not impossible, it is unlikely the motherboards are damaged.

You may also look online for rebuilt power supplies that are beefed up from the originals.

Be sure you have a good surge suppressor and surge suppression on your phoneline if you use dialup. I also recommend surge suppression on your ethernet connection as well.

Testing a power supply


Most commonly it is the power supply. Rarely it is the motherboard when it just stops working with no other signs. You can take a power supply from another computer and test but I bet it is definitely the power supply. You can purchase a power supply tester for around $20 or so but you can get a power supply for not much more than that and test it that way.
