Red led Light blinks twice

HP Recommended

 

light blinks red twice

Hi all,

 

"light blinks red twice" is what I get when I attempt to put on one of my systems.   On checking the meaning of the code I find that it means "Processor thermal protection activated".   What is this and how do I resolve it?

 

The system is HP Dc7700 SFF and is running on Win8.1 (32bit) that is giving the problem.

  

Please help.

Broaden your search.  Turns out quite a few of the higher level business class HP workstations use the same crisis codes as the high level HP workstations do.  Look up the HP standard for two blinks, two beeps.  It makes sense..... how can the processor get too hot?  I'd look at the fan for the processor's heatsink first.

 

If the fan it not working well then look at both sides of it... one will have the fan's label at its center, and you generally can buy a HP equivalent via eBay or Google search.  Don't get a non-equivalent because that will unbalance your system.  Voice of experience...

Some HP beep codes overlap, and it appears to depend on the BIOS being used by that PC/workstation.  When I did a search for HP + 2 beeps there is quite a variability in causes.  Are you sure you found the beep codes for your specific HP Business PC?

 

The rapid shutdown you describe is not due to a fan issue..... it takes some time for a processor and the heatsink plate above it to heat up to a thermal shutdown even if the fan is not plugged in or has failed.
