Hello, my server cannot open, neither can I enter BIOS.

It said, "chipset heat sink not detected, system halted "

Please help, what's the problem ?

Thanks!

The problem is exactly what the error message says - the heat sink has come
off the processor and the machine has shut down to prevent overheating. It
may be too late and the processor may already be fried, but you'll need to
open up the box, apply thermal paste, and reattach the heat sink and see.

Since you didn't understand this basic error message, call in a professional
computer repair person. I'm not saying this to hurt your feelings; just
being practical.

It could also be the processor chipset and not the CPU.
Open this pdf file from Intel and see page 11 of the document:

You also did not mention the brand of server you have, who made it?

It means exactly what it says--a missing (or perhaps just loose) heat
sink.

Since you don't understand the message that's a clear indication that
you don't know enough to fix it yourself. Get a pro. Don't be
surprised if the board is toast--thermal shutdowns don't always react
fast enough to save the equipment.

Just for grins, does this hardware detect the missing heatsink due to excess
heat, or is there some other sensor mechanism that detects its presence?

I've never encountered a board that would tell you that so I don't
know how it's sensing it. The intent is obvious even without the
knowledge of how it figured it out.

Maybe it is.... If it's just the device passing a threshold temp, then
there's really no way the system knows why, unless the fan is not turning
(another sensor). Saying the heatsink is loose in this case is just a guess,
and probably correct most of the time.

But if there's some mechanism that detects continuity or something through
the heatsink mount, then that's a new thing that I would like to know more
about. The Intel doc JS mentioned doesn't give any clue.

Nobody here has any idea what you are talking about. You're probably using a
website to view Newsgroups when most of us use a newsreader program such as
Outlook Express which comes with Windows.

Without replying to the original thread or quoting the original thread,
nobody understands.

I just noticed your post and you find this may
be a good solution if the spring loaded retaining
clips/connector are still good. I removed the heatsink,
cleaned the surface with Arctic cleaner #1 & #2
http://www.arcticsilver.com/arcticlean.htm

Then carefully removed any old thermal pad or grease
using a soft link free coffee filter from the ship on the motherboard

Next I applied a small dab of non conductive Arctic Ceramique
to the top of the chip and remounted the heatsink.

You could try this product
http://www.arcticsilver.com/arctic_s...ive.htm#aserev
to glue the heatsink in place, and solder a jumper wire between the pads
where the 2 U-shaped connectors are. This will complete the circuit for the
heatsink sensor, and the adhesive will hold the heatsink in place.
