Solved No power up dell optiplex sx-270

August 18, 2012 at 10:49:23
Specs: Windows XP, P4/Dimm
I was given this computer, but it does nothing when I push the power button, no beeps, no fans, no lights, no sound, no picture, no HD spin up..... nothing. I swapped out the cpu and memory ...... still nothing. The only signs of life are two lights.... one on the power suppy, the other on the motherboard (opened unit). (The power switch light does not go on.)
Any suggestions would be appreciated.
Thanks,
...... john

Likely a power-supply failure (or hopefully, a loose cable), or possibly bad caps. SFF (small-form-factor) units tend to be somewhat skimpy on the power supplies, and sadly (assuming it is the problem), you'll have to find a replacement specifically for that unit.

If it's bad caps (GX270's were known for such) then look here for replacements:

Hi,
Was the SX-270 also known for the bad caps problem?
Thanks,

Yep:

Also, link above is to the GX270 replacement caps; should have posted this one for the SX270:

Yes...... I see the culprit, one of the large caps... has brown crust around it's top. I don't think I'm going to bother repairing it. From the sound of the link you sent me, it's probably going to give me more trouble.
Well, it was free anyway. I'll just strip it for parts. By the way..... how can I get the board out. I removed all the screws, but it still seems firmly set in.
Thanks,

"From the sound of the link you sent me, it's probably going to give me more trouble."

Actually, if you replace all the caps (as sold in the kit), you'd probably never have any more trouble, capacitor-wise, anyway.

If your determined to scrap it:

Hi T-R-A,
No, I'm not determined to scrap it, but I have 4 computers here, and no real need for another.
Thank you very much for your help. I appreciate it.

No problem. And I can understand; having 20+ machines myself, another "mouth to feed" sometimes doesn't seem too appealing...

Twenty ........ WOW!!! You must be saying to yourself, "Why doesn't he want another machine; after all..... he only has four." ;--)
Oh.... one more question. This system has a 160GB 21/2" drive (much larger than any of my 31/2 inch drives). Is there any reason I couldn't use it in my 'large' desktop? And .... why don't people regularly use the 21/2" drive instead of the 31/2"?

To use a 2½" drive in a 3½" bay, you'd just need an adapter similar to this:

http://www.delock.de/produkte/G_610...

(sorry, that's the first link that Google found---I wouldn't expect you'd want to buy it from a German website). Make sure that your "large-desktop" would support a drive of that size first.

Since they're a little more compact than the 3½" version, they're a little more expensive to make; being designed primarily for laptops and, as you've found out, Small Form Factor machines (both where real estate is at a premium). That's generally why you don't see them in larger machines...

Thank again T-R-A,
Yes..... I think it will work. I connected it to my machine using a USB adapter, formatted it, and cloned my OS to it (using XXClone); but I can't run it from the USB port, so I'm not sure if the clone will work or not.
Thanks for the shortcut. I'll get one of those and try it out.

Hi T-R-A,
After I bought the adapter (2.5" >> 3.5") you recommended, I connected the 2.5" clone drive (I made of my desktop OS via the USB port) to my desktop master.
At first it looked good, even booted into windows (xp) and seemed to run well. That really surprised me, so I decided to run it through windows disk checker, which repaired a LOT of errors. Thinking it might be alright I started to use it, and found that I had no sound. So I recloned it by attaching it as a slave this time (using the adapter you suggested). This way it works fine. To make a long story short.... the clone produced through the USP port, worked, but had a lot of flaws.
Thanks again for your help.
