Computer Power Supply Troubleshooting – How Mr. Ronaldo Repaired His Computer's Switch Mode Power Supply

If you're having some problems with your computer power supply troubleshooting, then you definitely want to take a few moments to read the following story.

This story will give you some insights on how to effectively troubleshoot and repair computer power supplies – specifically switch mode power supplies (SMPS).

It's about Mr. Ronaldo, a former futsal player turned electronics technician.

WARNING: This story has a VERY tragic ending…If you cry easily, please keep some tissues by your side.

Mr. Ronaldo used to dislike repairing computer SMPS because unlike linear power supplies, he founds SMPS designs too complicated to figure out. Plus, he was still a beginner technician.

So here's what he did…

First, Ronaldo downloaded a thick, user-friendly service manual on how to conduct proper computer power supply troubleshooting. By the way, you may click here for details…

See, Ronaldo knew the importance of using a fully illustrated technical guide on repairing switch mode power supplies.

He knew that he'd learn better and faster by reading step-by-step illustrated guide, as opposed to reading a text-only SMPS service manual.

Ronaldo has read all the necessary details including schematic diagrams, how to identify the components available in various SMPS, block diagram, common issues of SMPS etc.

All these and more were fully explained in the downloadable guide. So Ronaldo was ready to perform his first computer power supply troubleshooting.

First, he took the necessary measurement and found that the power supply had overvoltage problem. Next, he took off the casing and came across several dilapidated electrolytic capacitors.

And that's not all!

He also discovered that some of the major components were stained with decayed glue! So Ronaldo promptly scraped off the decayed glue. He did it very carefully because he did not wish to compromise the components.

Ronaldo also replaced the dilapidated electrolytic capacitors with new ones. Next, he plugged the SMPS to a "test" hard disk and motherboard.

As a precautionary measure, he did not straightaway plug the SMPS to the actual CPU.  Ronaldo learned from the repair guide he downloaded earlier that the high output voltages problem might still linger.

Thankfully, the power supply works on the test hard disk and motherboard. Measurements were made and the output voltages were deemed stable.

Finally, Ronaldo connected the SMPS to the actual CPU. Success! To celebrate his first successful SMPS repairing work, Ronaldo went out and grab a cold beer.

And then he sat on his favorite couch, turned on the TV to watch his favorite football/soccer team, Real Madrid. They were up against Barcelona…

Barcelona won 2-0! Mr. Ronaldo was so upset with the outcome that he committed suicide…A tragic ending to an up-and-coming electronics technician.

R.I.P Mr. Ronaldo…

Still if you need a step-by-step downloadable manual on how to conduct precise computer power supply troubleshooting and repairing like the late Mr. Ronaldo had, then go ahead and follow this link now http://www.smpsrepair.info

Pay a visit to the supply of energy - Analysis of laptop computer energy adapters and upkeep Laptop computer energy adapter will be the source from the function power, that is a high-quality switching energy provide, supply-batteries  its work Rules and color Tv and other appliances in the switching energy provide will be the very same, its part would be to present a steady notebook Low-voltage immediate current (normally among 12 ~ 19V).
Universal laptop computer AC adapter Notebook power adapters are totally sealed little quantity set Bucks, though its usage of energy is frequently up to 35 ~ 90W, so the inner temperature is higher, specially in sizzling summer season Day, touch the energy adapter will function in a sizzling feeling. Because of this, the energy adapter failure Rate relative to other elements of notebook computer systems is still fairly higher. Harmed energy adapter soon after the buy of a complete New to spend a lot of hundred bucks, from used vehicle markets may also must hundred pounds. In truth, countless of damage and power adapter Not significant, a bit information of the consumer to understand a lot of the circuit can try to repair, this article are going to be IBM's "meat bone" energy Source adapter (16V, four.5A), as an example, describes the disassembly and painless upkeep for the reference.

While the PPTC device can not prevent failure, but they are able to respond rapidly to restrict the current to a secure degree, thus helping to prevent harm to the downstream gadget failure. Furthermore, varistor  gadgets in little type element tends to make them simple to use space-constrained purposes.

As data price grows, circuits turn into more compact and far more delicate to shield equipment from damage triggered by transient voltage circuit will become much more necessary. HDMI, USB and DisplayPort requirements: the finish user can touch the electrical connector have to have overcurrent safety. Overcurrent protective gadget must be no consumer handbook intervention is usually automatically restored, and its pre-set the set off threshold should be higher as opposed to permissible transient current protection to prevent accidental movement.

can i rigg a computer power supply to work as a normal power supply?

i want to run a mini fridge off of a power supply from a computer. it's a small (300W) ATX 12V 2.0
i have tried just hooking up a case fan to it and it wont work. i took a multimeter to it and it shows nothing... is there a block in the PSU if it's not connected to a motherboard? if so, how do i bypass it?

The tough question would how many watts does it take to run mini fridge and do you know there is two side to PS +/-5 and +/-12 Even if you figure out the swicth part you would have to fiqure out the controled voltage part. So don't try it for you own good.

Here a cheep Idea that could be work out with a little Tech as your self.

You would still need to rig up the mini fridge to a male plug but you can get them allmost anywhere even off you car cell phone charger. I have 3 or4 laying around in my house.

Origami stroller folds up with the push of a button (Gizmag Emerging Technology Magazine)

Appropriately enough called the Origami, the new baby product from 4moms is
billed as "the world's first power-folding stroller." This means that it will
fold itself down into a compact car-trunkable bundle, at the press of a button
- another press gets it to open back up again. Evidently, however, that one
feature just isn't enough. It also has running lights and headlights, plus it
will charge your cell phone. There's no word yet on whether or not in can
perform diaper changes... Continue Reading Origami stroller folds up with the
