Optiplex GX520 Random Shutdown/Sleep
Hey Guys,
I am having some really wierd behavior, and random times my GX520 (Small form factor) shuts itself down (or sleeps i can't tell which) the screen goes blank and my power switch/led goes into a flashing amber state. This happens every so often, sometime while i am working other times when i look away. The only way to get it out of this state is to hold the power button until it turns off, and then turn it back on. Does anyone know what this might be.... i saw some threads on capacitor issues, but i haven't had a chance to open it up and look at all of the caps i thought i would ask here first to see if this is even an applicable issue. Any help would be apreciated.
Thanks,
Dinomight

Problem: Customers may report that Optiplex GX520 and Optiplex GX620 systems which ship in the Smith (MT) & Cypher (SFF) chassis shut down after 3-4 seconds of being powered on.
Discussion: The failure is caused by the power switch in the Front I/O Panel Assembly electrically shorting to a trace on the PCB which is directly beneath the switch.
The Front Panel P/N for the Smith (MT) chassis is X8921.
The Front Panel P/N for the Cypher (SFF) chassis is D9091.
Solution: The engineering teams are currently investigating this issue. If a customer reports this failure mode then it is likely to be as a result of a failing I/O panel.
Fix on Fail by replacing P/N X8921 on Smith chassis failures from service stock.
Fix on Fail by replacing P/N D9091 on Cypher chassis failures from service stock.

Hi Dinomight,
I have 16 GX520's and I have had the same problem on 2 of them. After a little research I discovered that the power supply fan slows down after being switched on for about 15 mins and when the temperature reaches critical, whammo and the amber light problem occurs as you've got.
Solution, get the power supply out, clean it and get a 70mm chassis fan replacement from any good parts store and replace it. That solved all my issues.

Tawnyman thanks for the post. You were absolutely correct, PC would shut down about 2 hrs after startup. I've done thorough test on HDD, reseated the processor, cleaned and applied fresh heat sink compound on the processor. Tested the voltages on the Power Supply and all is good, but keeps shutting down after about 2 hours.
Replaced the power supply fan and it has been running over 24 hours without fail. $3.00 fan beats the heck out of replacing $80 power supply!

You may have noticed a little bit more of noise also?
The CPU FAN has become noisier than usual; this means the PC maybe over heating.
I have the same issues and corrected them with the same steps.
Best of luck,

I have posted on this before Ketan,
My problem was the power supply fan slowing down after about 2 hours and overheating occuring. I replaced the 70mm fan in the power supply and the problem disappeared. These fans can be obtained over the internet or by recovery from other power supplies/pc's etc. The age of the pc's prevents an expensive fix in my opinion. Salvage a fan from somewhere and try it.
