HP Microserver Gen8 Cannot boot up

[carxman]

Hi all,

I really need your help. 

A few days ago, my microserver Gen8 was not up, I only see the power button LED was blinking Green. I try to press or long hold the power button, no respond. I could able to login to ilo but it only said my server was not power on.

I read many post on internet and found one of them have similar symptom and he fix it by change the cmos battery. I changed my CMOS battery.

After I changed the CMOS battery, the power button LED was amber now, I try to press or long hold the power button still not response. 

Tried unplug all hardware and re-sit, still the same. 

Please help. Many thanks.
