SOURCE: can I use a PowerLine

No. It is rated at 600 MA which is way too small. The acer needs a 60 watt adapter. Please search online for the best price and get the proper adapter. About $40.00

SOURCE: No 12 volt power output from my acerpower 1000 motherboard

This seems to have a motherboard none too dissimilar to that of a laptop. It's hard enough to get information on a typical desktop motherboard, and those for laptops are even more obscure. You are not however dead in the water yet. The power supplies usually have fuses on the board, they are usually either blue or green, sometimes have a little "hourglass" on them. You can check them with an ohmmeter. If you're lucky, there's one blown from an earlier fan or drive problem. Hope you can find it and a replacement.

How do I hardwire this unit for an in home use installation?


You would need to have a stable 12 volt DC power supply that plugs into a 120 VAC outlet. You can google these, and they come in quite a few varieties. The most expensive are the variable voltage "lab grade" ones, then the bench grade fixed voltage variety, and then the cheap consumer grade 12 volt 1 or 2 amp device designed for CB's and small 12 volt devices. But this will not work, because you are transmitting and could be putting out 40 or 50 watts with that thing. So you will need a good 10 amp to 20 amp dedicated transceiver power supply, unless you just plan on receiving in which case you only need a couple of amps and the cheapie will do. It's always better to have more amperage in a power supply. You then need to think about issues like back-up power with a gel cell 12 volt battery, which also would allow you to use the cheapie supply, because you would have plenty of current to XMIT from the battery. Schematic shows a very basic 12v - 30 amp supply. Good luck!

Fault finding


Power is going to the motherboard, and you know this by assuming?

An assumption would be you see the Power Supply fan spin, LED lights light up, and maybe computer case fans spin.

Not an assumption, and you would have tested the 3 main voltage power rails, coming out of the Power Supply.

The Power Supply in your computer is an SMPS.
Switched-Mode Power Supply. (Also is known as the short abbreviation - PSU. Power Supply Unit)

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

The Power Supply in your computer is a Converter.
It converts HIGH AC voltage into 3 LOW DC voltages.

[Depending on country,
USA = 120 Volts AC. UK = 240 Volts AC. Japan is 100 Volts AC, but may depend on area. Australia = 240 Volts AC. India = 240 Volts AC. HOWEVER, do not write the above in stone. I may have made an error ]

The 3 low main DC Voltages coming out of the Power Supply is;
A) 3.3 Volts DC
B) 5 Volts DC
C) 12 Volts DC

Orange wires carry 3.3 Volts DC
Red wires carry 5 Volts DC
Yellow wires carry 12 Volts DC
ALL Black wires are Ground wires. They can also be called Negative wires.
This is a DC circuit now. There is a Positive, and a Negative.
Orange, Red, and Yellow wires are power wires, and also Positive wires.

The first part of your diagnosis will be to test those 3 main voltage power rails.

[Digressing;
Using an example;
There are many Red wires coming out of the Power Supply.
These are 5 Volt wires. They are Connected TO, the 5 Volt power rail in the Power Supply.
ALL 5 Volt wires end in one place, in the Power Supply.
The 5 Volt power rail.
When you test just ONE red wire, you are testing the entire 5 Volt power rail coming from the Power Supply.

This also goes for the Orange wires, and Yellow wires ]

With the Red 5 Volt wires, and Yellow 12 Volt wires, you could just use a 4-pin Peripheral power cable to check them,

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

Multimeter set to DC Voltage, the red (Positive) probe lead of the multimeter; touches the female metal terminal connector, for the Red wire.

http://www.mcmelectronics.com/product/28-9420&utm_medium=Affiliate&ref=cj&utm_campaign=CommissionJunction&utm_source=CommissionJunction?t=2&utm_expid=8634549-14

The black (Negative) probe lead of the multimeter, touches a female metal terminal connector, that goes to a Black wire.

You should be reading 5 Volts DC.

Same thing for the Yellow 12 Volt wire.

With an Orange 3.3 Volt wire, this changes.
A straightened out paperclip is inserted, down into the BACK of the ATX main power cable's connector; AND into a socket hole with an Orange wire in it.

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

The straightened out paperclip, slides down into the socket hole, with the Orange wire in it.
Slides down into the socket hole, RIGHT NEXT TO the orange insulation of the wire, and MUST go down far enough; to Touch that female metal terminal connector.

EVERY wire going down into the ATX main power cable's connector, ends in a female metal terminal connector.

Same thing is down with a socket hole that has a Black wire in it.
ALL Black wires are Ground wires. (Negative)
You can choose ANY socket hole that has a Black wire in it.

Now touch the two probe leads of the multimeter, to their respective straightened out paperclips.

Red (Positive) probe lead of multimeter, to straightened out paperclip in Orange wire socket hole.
Black (Negative) probe lead of multimeter, to straightened out paperclip in Back wire socket hole.

You should be reading 3.3 Volts DC.

(Or if your multimeter kit has special probe lead, that would take the place of a straightened out paperclip, of course use it instead)

Know this;
A) If ALL of the LED's ('lights') were on at once, they would use less than 1 Watt of power.

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

C) A typical CPU (Processor) can use 51 to 130 Watts of power.
Just depends on what Processor (CPU) it is.

This is why a Power Supply with a weak voltage power rail, will not have enough power to turn the Processor ON, but will have enough power to light those simpy LED's, and spin fans.

Hp computer tower will not go on


Would that be an LED (Light Emitting Diode), blinking on the back of the Power Supply?

If so, instead of being an LED that indicates the Power Supply has power to it, it has now turned into a diagnostic LED (Light), and is telling you the Power Supply is bad.

Do you have an economical multimeter, so I can guide you in testing the 3 low DC Voltages; that come out of the Power Supply?
An economical multimeter can be purchased for as little as $5 to $12.
I have seen them on checkout aisle racks, in major discount stores.

The dangerous high AC voltage, is kept contained within the metal case of the Power Supply.
(100 to 240 Volts depending on what country you are in)

The Power Supply is a Converter.
It converts the high AC voltage into 3 low DC Voltages;
3.3 Volts, 5 Volts, and 12 Volts.
In comparison two D cell flashlight batteries produce 3 Volts DC.

OR;
Use a KNOWN to be good, Compatible power supply; for a temporary test unit.

{"Honey, I'm going to borrow the Power Supply out of your computer.
I'll put it back when I'm done."
"What? I'll be sleeping on the couch? K"} (Lol!)

Also, is the inside of the computer dirty?

I have a dell computer. when i turn on the tower and monitor i get just a black screen on the monitor. i have pushed a few buttons on the bottom of the screen and it just says power save mode please use...


No, it's the Power Supply.

Power Supply has a weak voltage power rail.

The monitor goes to Power Saver mode because it is not receiving a video signal. (No Signal)
This is because the computer is not working.

{You can also test the power coming out of the Power Supply.

The Power Supply in your computer is an SMPS.
Switched-Mode Power Supply,

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

It converts the AC electricity from your home, or business, into DC electricity.
There are three main voltages produced;

A) 3.3 Volts (3 point 3)
B) 5 Volts
C) 12 Volts
All are DC voltage

Two D cell flashlight batteries produce 3 Volts DC.
(In case you are worried about being shocked.
The 'bad' electricity is contained inside the Power Supply's case)

If you do not have a multimeter, an economical unit can be purchased for around $8 to $12. A LOT of stores carry them. An auto parts store is one example.

Orange wires are 3.3 Volts
Red wires are 5 Volts
Yellow wires are 12 Volts.

ALL 3.3 Volt wires end at the same 3.3 Volt power rail in the Power Supply.
Same with 5 Volt wires, and 12 Volt wires.

You can test ANY Orange wire, or any Red wire, or any Yellow wire.

ANY Black wire you see is a Ground wire.

The red probe lead of the multimeter is the Positive lead. The black probe lead is the Negative lead.

The Positive probe lead is touched to a positive wire.
Orange, Red, or Yellow.

The Negative probe lead is touched to ANY black wire. ALL black wires are a Ground wire.

The function knob on the multimeter is set to DC voltage. (Dotted line over a solid line, with a dotted line under the solid line. The curved S line over a solid line is for AC voltage. This = No)

If there are different scale settings, set the function knob to 0-50 Volts. (DC)

Roadmate 2000 power supply over-voltage


The roadmate operates on five volts dc. Look at the back of the unit and it says so there. Inside the cig lighter plug that comes with the roadmate 2000 is a transformer that converts 12 v dc to five v dc. You used the wrong charger and put twelve volts across a unit that only handles and requires five volts.
Check to be sure that you used the correct charger. it sounds like you did not. It may be possible that the charger was still wet or was damaged when wet and that it shorted out.
Radio shack sells a charger for the car that is made for magellin roadmate 2ooo. It includes several different tips including the one that fits this gps unit and the output is five v dc. It is possible that what you smelled was the charger cord and not the gps unit itself.
I used the wrong charger on mine and had a similar problem. I bought this charger and all is well. radio shack cat no is 20-151. Get it soon because it is on sale for about thirteen dollars and is discontinued. As of today, sat jan 12, 2008 they still have them in stock at most stores. You can call ahead or look online and it will even tell you which stores have them, or you can order online as well.
No, if it is the gps unit titself, do not try to mess w the circuit board. Its cheaper to buy a new one. good luck to all w similar problems and ALLWAYS check to see that voltage and ac or dc symbols, as well as polarity, match up. If not bring your electronics to radio shack Before powering up and they can check all of this ffor free if you are unsure.
