hp zbook 17 flashing power light will not turn on

HP Recommended
hp Zbook 17
Microsoft Windows 8.1 (64-bit)

hey there people looking for a little help with a Zbook 17 (2014) I just picked up its running intel i5 8 gb ram 500gb hdd it will not turn on  when connecting the power cable i'm using a  dell 10 amp power supply until the hp one turns up all I get is the light next to the plug is on the power button light flashes the caps lock button flashes the power light on the front flashes and the battery light flashes yellow

i'v tried the normal things like remove one part at a time like the hdd the ram etc still the same flashing also the hard reset holding the power button down did nothing

any other ideas would be great

the dell power supply I tried looks the same size (its a big supply) as the hp oem one I ordered only difference is the hp is 11.8A and the dell is 10.8A

BIOS Flashing light error codes for Computers released between 2011 and January 2015.

On some computers, the motherboard can flash or change the colour of lights on the outside of the case, such as the power button LED and the hard drive activity LED. For computers that support this technology, lights blink and provide a beep to indicate a failure condition.
