Power Problem

Hello there, I have HP Folio 9470m and now am having a bit of issues with the PC.
The problem with the laptop is that, when the battery is placed in the laptop without booting, the orange and White LED light will be blinking.
If I take off the battery and plug in the AC directly, the same thing happens.
In any of the situations, when I try booting the laptop, it doesn't boot.
I have taken off the battery, disconnected the AC source and pressed the power button for 60 seconds and later connected the AC and tried to boot but it won't boot.

Can somebody please help me out?
Will be very much appreciated...
Thanks in advance
