What! not if you know what your doing and that doesn't take much skill.
Replacing the power unit is a real pain on the rc500
1. You have to remove the motherboard to get it out
2. A replacement is hard to find, acer and acer parts don't stock one and have only found a couple on ebay which are really expensive.
3. Hard to migrate to a new case because of the form factor.

solution: Get a new pc or unit and salvage some of the parts

You cannot change a power supply unit on a computer, you will damage the whole computer or you can even fry yourself.

Buy a new computer.

Have a E-Machine that keep displaying in powersave mode


eMachines are a budget computer.

Designed to save the consumer money.
One of the items used that cost is saved on, is the Power Supply.

Power Supply is generic, and of low quality.
1) Low quality Electrolytic Capacitors
2) Low quality Power MOSFETs
3) Low quality Rectifier Bridge
4) Too small a gauge of wiring is used

Plus most consumers do not keep the inside of the computer clean, and if they do the Power Supply is usually neglected.
The two leading causes of desktop computer failure; the computer is dirty inside, and/or the Power Supply is bad.

With a weak voltage power rail you may see LED's light, and maybe fans spin, but there won't be enough power to turn the Processor on.

[No Processor operating, no computer. No computer = no video signal to the monitor. No Signal, Power Saver Mode, or Sleep Mode is indicated ]

1) If ALL of the LED's were lit up they would use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can use from 51 to 125 Watts of power.
Just depends on what Processor it is.

See if there is an unused working computer that has a KNOWN to be good, Compatible power supply; that you can use for a test unit.

Or use a multimeter to test the three main voltages, coming out of the Power Supply
3.3 Volts (DC) [ Orange wires ]
5 Volts (DC) [ Red wires ]
12 Volts (DC) [ Yellow wires ]
[ALL Black wires are Ground wires ]

I had lost power in my house & we had unplugged the computer. Now power back on in the house , we plugged the computer back in but the computer won't turn on. Only a green blinking light. We unplugged...


hi , if the computer was plug ed in while power went out and computer was on .you might of got a surge , in that case your power supply is out , its very easy to take off. open the case find the power supply unit dissconect the color coded wire clip from the mother board , also the ones on cd rom and hard drive once disconnected , there are 4 screws on the side of the power unit take those off and the power supply should slid out. next take it to best buy computer store . and they can match the power supply unit foe you its to get higher voltage power unit hope this helps

The computer powers on but will not pass the compaq bios screen, i cannot access bios either, it is totally frozen???


It may be a number of things but first I would try the poer supply as if the voltage is too low as the computer tries to load it draws more power and will seize up, next I would try some new RAM as if there is no available RAM the computer cannot function.
If it were the hard drive, I would expect a hard drive error report.

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.

Had a power surge... a of my external harddrives work; however, can't get either computer to power on... Gateway GT5654 or my wife's Gateway GT5408.. on my wife's motherboard, there is a green light......


You can get a powr supply for this, but if the surge went passed that and smoked the motherboard then your going to need to replace that as well but a new poer supply should shore this up and you can get them from frys.com,tigerdirect.com you be glad you did!

Hard drive i not recognized - and clicks


Is this an external hard disk?  If it is it probably indicates that it cannot get enough power from the USB.  You need an external power source.  use wither a second USB port or a plug in poer supply.
