LED blinking 6 times red slowly then 3 times white quickly PC wont turn on

z240 work station tower T9U05PA
Microsoft Windows 10 (64-bit)

I cant turn my z240 tower back on.

 

I can't find the beep code or fix 

 

the power led light is flashing 6 times red slowly then 3 imes white quickly.

 

I've tried unlpugging replugging AC - unplugging and htting CMOS button (reset)

 

Holding power on 30 seconds then quick - a few other fixes mentioned along these lines

 

it's not doing anything, any ideas?

Hi

 

https://support.hp.com/us-en/document/bph07107

 

Is there a match?

 

Go to http://www.hp.com/go/techcenter/pcdiags . The HP PC Diagnostics home page is displayed.
 
 
OR
 
The closest I get is 5/3.
5.3  The embedded controller has timed out waiting for the BIOS.

Thank you for replying.

 

The link https://support.hp.com/us-en/document/bph07107 - is there a match - I came accross this last night and they did not work.

 

This I wasn't able to find but does seem most likely to be what is going on. 

The closest I get is 5/3.
5.3  The embedded controller has timed out waiting for the BIOS.
 
I have no idea how to adress this though.
