Other Server will not turn on!!

Hi people I'm hoping someone can help!!

I have just received an HP ML310 G3, after some tinkering I got it started and booting by removing a defective RAM stick, shut it down and went to bed. The day after it will not power on at all!
motherboard has a green light and the power light on the front is solid amber which is normal

so far I have tried:
removing and replacing RAM
tried a different PSU
disconnecting everything one by one
disconnecting the power lead and holding the power button down for a min or two

All with no joy it sits there tormenting me!

Any ideas are welcome please any advice!!

Thanks in advance

 

Was it working when you received it?

 

no, was turning on but not booting to OS, removed a RAM stick and that worked fine, starting using it and then shut it down for the night, returned the following day and nothing since

 

Did you buy it new or used or ?

I'd be contacting the seller / retailer...

 

is it that it will not power up at all or do the fans spin then nothing? or power slightly and fail? or something else?

 

was given to me used, had not been on for 6 months prior but last person said was working fine.
No power at all, motherboard light is green and light on front is amber. no fans spinning no life at all. was starting to think maybe the mobo is dead but is shows a slight sign of light in that the light is on green when power is connected

 

Aye I'd say mobo or PSU, Try pulling the PSU out and giving it a clean on the contacts. Unless its not a removable PSU in which case that server really isn't worth saving.

 

Could be the switch itself?
Normally with the HP servers... even if the board is knackered it'll power up the fans at full pelt and stay at full pelt.. not do nothing at all....

 

I haven't tried playing with the switch/button itself yet, I will try this evening and post my findings
knowing my luck with this thing its probably the switch

 

still have nothing, still seems very strange how it wont turn on after being used, restarted and then controlled shutdown. im out of ideas

 

Does the power button click when pushed?
Is everything 100% in the correct place (especially memory in the correct channels)?
Is the PSU in the correct slow at the back?
Is it still showing the orange light?
Have you pulled the CMOS battery & left it for an hour (unplugged from the mains as well)?

 

Yep tried all that!
Im starting to thing that the mobo has died but part of me thinks not hence the 2nd opinions needed!
starting to think it wont be joining the other stuff in the cabinet at this rate!

 

RAM ECC or NON ECC some server require it some don''t?

 

RAM is ECC

 

On the front of the server does it have any Lights amber etc? Aldo have you tried removing the PCI cage if there is one(cant remember the last time i open an ml310).

Reset the CMOS/BIOS remove everything but the ram cpu etc

thanks have come across that link before which led me to believe it might be the switch but haven't tried anything yet.
It has an amber light on the front which is the standard standby light i assume and the mobo light appears green inside with power hooked up so all seems good inside.
I also removed everything one by one and replaced one by one and still the same.

 

Quick update, I tried the old screwdriver on the pwr switch pins to see if it was the switch that wasnt working but still nothing starting to think I will have to admit defeat on this one

 

What does iLO say?

 

Sorry for slow reply but moving house and revising has taken priority!! after more tinkering and diagnosis the mobo seems dead! hoping to pick a cheap one from eBay!
Thanks for all your help/advice!!
