Product: HP z820
Operating System: Microsoft Windows 7 (64-bit)

Hi, we need assistance with z820, it beeps twice and flashes red light twice and doesn't boot to Windows 7. We have tried to:

 

- vacuum the computer

- re-seat all possible components

 

We're considering:

- flash Bios

 

I was wondering if HP would give us a hint on this. We have a few hundreds in our institution and I was wondering whether there would be a way to rectify the situation.'

 

Thank you in advance.

Hi:

 

According to chapter 4, page 145 of the service manual, the two beeps, two red flashing power LED code indicates a problem with the CPU cooling system.
