Fan voltage must be the same as the one you want to connect it to

    First priority is voltage compatibility, if the voltage is not correct, you can't use the fan. Most PS fans are 12 volts, you could tap on of the 12 volt leads to power this fan

How to replace power fuse

You have to unscrew and open the charger. Inside you will see the main board and the Power Suply Unit (black box). If the problem is in PSU have to open it and change the fuse inside. May need some soldering skills there. The position of the fuse and the type depends on the manufacturer. There are many fake imax models and never have the same PSU . Even the original has different psu.
Now if the problem is on the board you need more experience in electronics and soldering. In this case better buy another one from ebay.

Wont start

If you're not getting a beep code then you can be almost certain the problem does not lie with any of your hardware aside from your CPU.

It is possible your CPU is overheating, in which case you can try to increase the fan speed in the CMOS setup. For further troubleshooting I recommend using isopropyl alcohol to remove the old thermal paste from the heatsink and CPU die, and apply a new, small, pea-sized dab of thermal paste to the CPU die (after which you remount and lock into place the heatsink and CPU fan).

Sometimes these startup problems are very simple, and since you said the fan slows down rather than stopping, it could simply be you have a loose connection somewhere. I'd start with the PSU cables for the motherboard and CPU, and then the fan-monitoring plugs on the motherboard.

Also, it never hurts to load the default CMOS setup, and if you have any expansion cards you'll want to reseat all of them.

When turning computer on, fans start then shuts down with one long blue light flash around power button. Suspect power supply

You could be right in your analysis, however, before replacing the PSU unit (a weak point with both Medion and E-machine computers) check the following:

  • That the Power button is not sticking in the case
  • Inside the computer case, the PW wire is firmly making contact with the motherboard (switch to motherboard 2 pin wires)
  • That the PW wire does not have a kink in or is broken giving an intermittent fault
After checking those:

  • Disconnect HDD, DVD Writer, remove 1 stick of ram and test with each removed, replacing each in turn. If the computer still does not boot, then check the ATX connector to the motherboard and the 4 pin auxiliary CPU connector (black and yellow) if fitted
  • Remove the motherboard and check underneath to make sure there are no items of metal that might be causing the board to short out. Check the board underneath for signs of blacking or burning.
  • Replace the board and refit all connections.
  • Inspect the capacitors on the board (small cylinders) if any are bulging at the top, leaking and with a brown residue, the board is failing and will need replacement.
  • Finally, remove the PSU and test with a known good one.
  • If this fails and the board shows no blowing capacitors, the problems may now lie with a blown CPU or micro damage to one of the motherboard circuits

Hp pavillian a235 no power. main lead and fuse ok

By "fuse" I'm assuming you mean the fuse in the AC lead

There are several possible cases.

  • If the led on the back of the PSU (if fitted) is not glowing, then assume the PSU has failed. Usual causes of this are some of the capacitors going, resulting in power not being converted to the 12 volts that the system uses. Best way to check is to substitute a known good psu for the one installed and see if that works.
  • If the psu is known to be good, visually inspect the motherboard for blown or leaking capacitors, they will show as bulging at the top and sometimes with a brown residue.
  • Check the connections from the psu to the main atx power socket. Make sure they are tight.
  • Disconnect all peripherals and try to power on with just the fan and 1 stick of ram installed. Sometimes a faulty component will stop power getting to the system
  • Check the cpu, a dead cpu again can sometimes stop power getting to the board, you can also see if the heatsink is getting warm as it is powered up, if it is not, then the cpu is likely dead. Check also with a multimeter, the voltage from the 12 volt rails ( connectors that fit into the hard drive etc) red to red black to black, if there is no voltage showing, there is no power reaching the rails from the psu.
  • (on no account try to check the inboard power to the psu, or attempt to dismantle it).
After that, it would seem that the problem lies in a burned out circuit on the motherboard

Computer is not booting up. Usual blue light over power switch is red.

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they are probably old and faulty a computer needs its connections to have an end so any faulty leads will end up with a computer error

hope this will help

Hp530 Ultra Slim starts and stop after 3-20sec

I have had this once before, and then it was one of the hard disk cables which was interfering with the fans inside the case. In my PC it was the PSU fan which was being halted. Try moving the cables around inside the case and ensure none of the corners where they are folded are protruding into any of the fans.

Intel Cpu Fan ReWiring

Here is the pinout for the wiring:

Pin Name Color 1 GND black 2 +12VDC yellow 3 Sense green 4 Control blue

In case this doesn't show...Black is Ground and Yellow is +12VDC.

Not sure if it will work w/o a Sense (Green) and Control (Blue) line though.

Are there any fans moving in the case? As in, are you getting any power? If no fans are moving, it's possible it's:
1) the power supply (PSU)
2) your 'jumper' from the power button to the motherboard has come unplugged
3) you're grounding out somewhere

One cheap-o way of testing a power supply is:

Turn your power supply off.
Unplug your power supply.
Get a paper clip.
Bend it into a U-shape with the ends close together.
Put one end of the paper clip into *the* green wire in the plug of the PSU.
Put the other end of the paper clip into a black wire of the PSU.
Plug in the PSU.
Turn on the PSU.
If the fan runs in the PSU, it's safe to say this PSU is in working order.

If the the power supply was fine, but when you hit the power button and it no fans inside the case move, check the plug from the case to ther "power on" jumper on the motherboard. if that's correct, I'd suggest removing the entire motherboard from the case and setting it onto a phonebook and see if it'll turn on there.

If fans are moving when you hit the power button, but no beeps, fans turn back off after a moment, ect:
1) Motheboard is bad
2) Processor is bad

These are the situations that are most likely.

Computers are picky about being played around in. You can look at them wrong and they'll stop working. Sometimes it's as simple as pulling them apart and putting back together again to make them work... at least in my experience. I wish you the best of luck.

Fan not lightning up

there should be 3/4 small led (light emitting diodes) on the inner of the fan check the integrity of the solder on the wire to this led strip if there are any breaks in this then it can be re soldered.

if the fan is part of the PSU (power supply uinit then consult your local pc repair shop do not open the PSU.

If its just a case fan it would prob be easyer just to replace the fan.

hope this helps
