HP ML115 G5

Hi

On boot up nothing appears on screen, it can't get to POST PROMPTS. The fan just continually stays on.

Any ideas?

Re: HP ML115 G5

my bet is CPU or RAM, try swap testing.

Re: HP ML115 G5

Thanks for the reply

Your suggesting to swap CPU and the RAM to see if it works, however I have nothing to swap it with. Or am I misunderstanding you?

Re: HP ML115 G5

well if you have enough DIMMs in it then you can take out half and try them in two goes, guess a single CPU is a problem though, try seeing if you have anything else with a compatible CPU, doesn't need to be the same, just compatible.

Re: HP ML115 G5

I only have 1 piece of RAM though. So I can't move it about, can I?

Re: HP ML115 G5

also, How do I find the serial number, where would it be stamped or written?

Re: HP ML115 G5

Hi

Update...

When I switch it on I notice 2 LED's light up. One just staying on - normal.

However there is one which is flashing which flashing. - Which is shown in attachment. (RED CIRCLE)

The writing (Vertical - Highlighted in BLUE square) reads from RIGHT to LEFT:

"CPU_FAN_FAIL_LED"
(Cant read this one as well as the others - might be wrong):
"DIMM_ECC_EFFOR_LED"
"OVER_TEMP_LED"
"System_FAN_FAIL_LED"
"HEART_BEAT_LED"

As you can see the LED is flashing above the "HEART_BEAT_LED", however it seems there is some sort of cover on the LED. Where as the other ones like "CPU_FAIL_LED" don't have these 'covers'. Does this LED symbolise something wrong with just the "HEART_BEAT" or any of the others.

Also, I am pressuming this flashing light is bad.
I am also pressuming this is causing me to not get any visual on the monitor and no POST.

any ideas?

Matt

Re: HP ML115 G5

heartbeat blinking seems normal to me.
it indicates some process is operational.
off or steady indicates an error.

according to the document in the link Larry gave. an ML115 G5 only has a single diagnostics led on the Mainboard.

Your description tells something else.
this maybe a connector for a flat-cable where the "cover" you mention is a LED someone mounted directly on the connector?

Re: HP ML115 G5

Ok, thanks.

I thought that as well. When I saw the PDF file saying it only had one LED, I was confused.

I'm going to try and recover the BIOS today with the Jumper.

Lets see what happens.

Hi

Update...

Got it working. I took the jumper out, put the ROMpaq for USB on USB stick. Booted the server up with USB in. Waited for a little beep melody. Turned off. Took USB stick out. Put jumper back in. boot up!

Thanks for the help
