Have a shinco ap14000 portable ac the p2 icon is on what does that mean ?


FAULT = ELECTRIC CURRENT IS TOO HIGH.
CODE = P2
CHECK POINT = 1. CHECK IF THE REFRIGERANT IS CHARGED TOO MUCH
2. CHECK IF THE VOLTAGE IS TOO LOW, POWER WIRINGS TOO THIN OR TOO LONG OR CONTACT BADLY.
3. CHECK IF THE OUTLET IS BLOCKED OR THE CONDENSOR IS DIRTY
4. CHECK THE OUTDOOR MOTOR WORK NORMALLY
COUNT MEASURE = 1. REGULATE THE QUANTITY OF REFRIGERANT
2. UPDATING POWER SUPPLY, CHANGE POWER WIRING
3. REMOVE OBSTACLE AROUND OUTDOOR UNIT OR WASH THE CONDENSER
4. CHANGE OUTDOOR MOTOR OR MOTOR CAPACITOR

Dell optiplex gx520 will not start, shows yellow light on matherboard with yellow blinking power light


Testing the Power Supply by unplugging the Processor, and Ram Memory?

UH, NO.

1) IF, all of the LED lights were on at once, 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 51 to 125 WATTS of power. Just depends on what Processor it is.

So yes,...a 2 to 3 Watt system fan will spin, with the Processor unplugged, and you have a bad Power Supply.

(Ram Memory typically uses 25 to 30 Watts for each module. { 'Stick')

You have a bad Power Supply. Probably dirty inside. It's a generic low quality power supply, anyway. Probably made by Bestec, HiPro, or Delta.

[ The cooling system for your SMPS (Switched-Mode Power Supply), are the Heatsink's used inside, and the internal Fan,

A Heatsink is a thin piece of metal with Tall, Thin, fins protruding from it.
The thin piece of metal absorbs the heat, then the tall, thin fins radiate the heat away,

The letter B is on top, of one of the two Input Stage capacitors.
(Radial Aluminum Electrolytic Capacitor's)

To the immediate right is what looks like a series of shiny Aluminum blocks, that are joined together.
(The blocks are fins)

This is a Heatsink.
To the right in-between C and D, is another one.

I Do Not recommend opening a Power Supply, even unplugged from power ]

Have an unused desktop computer sitting around, that has a KNOWN to be good, Compatible power supply?
Use it for a test unit.

A) Scroll down.
DC Power Connector P1, is a 24-pin ATX main power cable,

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

Make SURE the color code of the wires for the old Power Supply, match up with the one's in the test Power Supply, in this power cable.

Dell switched them around for a small period of time.

[ Orange wires are 3.3 Volts. (DC)
Red wires are 5 Volts. (DC)
Yellow wires are 12 Volts. (DC)
ALL Black wires are Ground wires.

What do you think would happen if a 12 Volt Yellow wire, was connected to a Black ground wire?

Yep, POOF!
Happened to a LOT of people in the past, with the computers in this small time period, when they refused to spend big $$$$ for a Dell power supply, and used an aftermarket power supply.

Check color code of 24-pin ATX main cable on the Old power supply, and on the test unit you are going to use. Also on the new Power Supply ]

B) DC Power Connector P2 is a 4-pin ATX +12 Volt power cable,

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

[ NOTE* Color of connector NEVER matters, on a power cable ]

Power for the Processor.

C) DC Power Connector P3.
These are just 4-pin standard Peripheral power cables. There are a few coming from your Power Supply. Misnomered as a 'Molex' power cable,

Dell Dimension L733R Windows Explorer hang


Hi, yes XP does have system restore, which you can access through safe mode, pressing the ESC key during bootup will get you there. I would not uninstall IE8, but disable by using Firefox which is a much safer browser for XP, you can down load this for free.
Hope this helps

get a tester and check the continuity of the wires on both ends of the plug...the 3rd wire is usually connected to ground but it's optional..it doesn't pose any danger to your system...

Dell 4700c will not power on white light on motherboard


Hi,
Is there any chance for you to check if the power supply blows air from inside of the power supply? If yes, on your motherboard, do disconnect the P1 cable or the main power supply cable that connects to the motherboard and the P2 cable which. and try to plug the power cord of the power supply and if the fan did not spin, power supply is the one causing the problem

You may also try to remove the RAM or memory card module from the motherboard and all of the PCI card connected to the motherboard. Try to turn on the system and check the power supply fan and the CPU fan if it will spin. If not then I recommend you to replace the power supply.

On the other hand, if the fan is spinning on the power supply after you remove all the RAM and PCI cards. And the power button light is flashing amber or solid amber color. Try to install RAM 1 by 1 to isolate the problem.

Let me know if the problem persist

Want to upgrade power supply on Dell Dimension 4700. Bought Rocket Fish RF-550wps 550 watt powersupply to install . Unable to proceede no schematics ror placing wireing


Hi there.
Rocket Fish RF-550wps PSU is standard ATX power supply.
Dell tend to use their own power supplies which differ slightly from standard power supplies.
I suggest you take or send the Rocket Fish RF-550wps PSU back as it won't fit and order one from Dell themselves, at least then you will have a guaranteed fit.
Once you have your new power supply from Dell (or a Dell ATX power supply) it should be easy to fit in.
Post back if you need any more help.

Good luck and thanks for using FixYa!!

you may consider reseating the P1 and P2 cables (from the power supply) connected to the motherboard.


you can go to www.support.dell.com and enter the service tag of your dell system (found at the back of your system) and look for the manual on how to add/remove the parts of the computer.

thanks.
