Try to do something proactive and this is what happens.
« on: July 27, 2014, 03:28:17 PM »
I noticed my home computer was looking a lottle dusty.  Some canned air later and the innards are nice and spiffy again.  Plugged it back in but no power.  Nothing.  Not even a flicker.  The only thing lit is the line power indicator on the power supply.  Other than that, zilch.

Gah.  This is all I need right now.  Hoping it's just a flakey connector.  Second best would be a knackered power supply.  I can swing that no prob.  I'll be more than slightly miffed if it's popped system board or processor.  I'm trying to keep the spends to a minimum since I'm job hunting.

Any way to bench test a power supply by jumpering a control circuit?

Not too old Dell desktop, by any chance?

I've got a customer whose Dell will (some of them) do that after a power glitch.  What fixes is it disconnecting power supply from everything, letting it die good and dead, then reconnecting.

About five years old. Dell Studio series.  Left the power unugged for more than five minutes to reset.  No joy.

Well, that's not good.  Found the power supply pinouts. Jumpered the control circuit and the power supply spun right up.

Sigh.  I think it's something on the system board.  Reseated all connections.  Verified that the power switch on the panel is operating.

I wonder... Would it help to try removing the CMOS battery to make sure I'm getting a full board reset?

EDIT TO ADD... It didn't.

Found a NOS factory board on evilbay for a whopping $45.  Impressed that the seller is in TX (Carrollton).  Crossing my fingers it's the system board and not the processor.  Guess I'll know in a couple days.  I haven't replaced a system board in over a decade.  What's the latest procedure on CMOS battery... leave out until board is powered up, or have installed before board power up?

Are you sure it's not your power supply?

CMOS battery.  Boards usually come with one installed.

When I jumper the control circuit on the mobo power connector the power supply spins right up.  Connected to the board, nuthin.

UN-educated question time.
Can you replace your jumper with a toggle(or whatever)switch?Is there something important on this board that an external switch couldn't replace?

I could, and pretty easily.  Don't really want to power up a questionable board and risk popping the processor, gakking a card, or killing a hard drive.

Any of those results are really unlikely.  Disconnect the hard disk, remove any cards in expansion slots, hook up the power supply to the board, and manually short the power switch header pins on the motherboard with a screwdriver.  See what happens.

Will have to wait until tomorrow. Currently in a relaxed physical state and enjoying no-cost libations.  (Translation... Sitting on my butt and drinking someone else's beer.)

I had a computer that I booted with a screwdriver for 3 years. I couldn't get my case's power switch to work so I just shorted the pins together on the header labeled "PWR". It would have been inconvenient if I rebooted a lot or if I put the side on the case.

The last power supply that died on me was working fine until I rebooted, then never came back up.

Up and running.  Turned out to be the power supply after all.  The 5v side was hosed which killed the power control circuit on the mother board.

Kinda grouchy that I blew $45 on a mobo but I still count myself damned lucky.  For ninety bucks I'm not only back to operational status, I also have a spare system board just in case.  I like that the new generic power supply has a genuine contact-style master power switch.  That'll come in handy during severe storm season.
