Refurbishing for a charity, PSU's failing regularly.

Does anyone know if this a common failing? We refurbish for a spinal charity, and the units are donated by a local hospital - but we are having a surprising number fail upon being connected to the power supply and switched on. The units are clean, and fairly free of dirt and grime. Any info would be welcome!

This is a common failing on the d530 desktops - we run about 300 of these and have had quite a few PSU failures

Computer won't boot - fan on cpu does not run - cd drive does not power up -


If there is no sign of life, then it is usually a power supply problem. Check PSU connector. If PSU fan does not turn on check the power cable. If power cable is good, test power from PSU using a multimeter and eventually replace PSU.

Refurbishing a Gateway that has a Microstar ms-6389 motherboard

If you would visit the website, there's a search box in which you can enter your MS number. You should find links to your drivers, and even the user's manual with all the specs., including what ram is compatible.

I need the color codes, and more importantly, the polarities of the tips that come with universal notebook power supplies. Thanks for any help.

Depends on the brands you are looking at.
The most common are these:

As Far as I know, the notebook PSU's follow the same industry standard colour coding as a regular ATX PSU.

(numbers expressed as V)
Blue -12
Red +5
Orange +3.3
Grey Power good signal
Green Power switch
Purple Stand by power
White -5
Black Ground
Yellow +12

Dell gx270 power and orange flashing light

Hi Mikeabcde,
I'm not sure how much help I can be in this matter. When I had the problem of a dead PC, showing only the orange flashing light, I was unable to do anything with the machine. As nothing seemed to work except the light, I randomly decided to (a), just push in the button for less than a second (which did nothing, then (b), hold the button in for 5 - 10 seconds, which immediately resolved the issue. Afterwards I talked to my son who is quite a guru in these matters, and he told me that this was "standard procedure" for resetting this machine. I had gotten into trouble when I was reconnecting a CD burner power supply while the PC was on.
I believe my machine is a 2004 model, which had been "refurbished" I have to say that I could find no evidence whatsoever of any refurbishing - it looked brand new in every aspect. In researching online, there does appear to be a capacitor problem with this model, although I have had no such problem in over a year of use. I don't believe that overheating is a major issue with the Dell GX270. I have never known dust in the CPU fins to cause excessive overheating. Obviously, if the machine is located in a way which would prevent reasonable ventilation around the case, overheating might then occur, but this would be unlikely.
Replacing a bad capacitor might be a solution, although it might be difficult to identify the problem cap., since they can go bad without any visible indication. Replacing the power supply unit is a possibility, but the cost might not be justified for this relatively inexpensive machine. Good luck, Mike. Hope everything works out successfully for you Have a great day!

Old Computers.

not likely. They may not have anyone that's up to speed on that old of a system. I'd run a craigslist ad, and see if you can find a tech folk person, that likes to do this sort of thing(like the Victrola version for computers, eh?)

Tower wont turn on

Your power supply inside the CPU has finally failed. I agree with Smooth_Gecko, to be on the safe side, borrow one and test it first.
