Armada M700 power problems

I have seen others complaining about their Compaq Armada M700 laptops
refusing to boot. My one has the same problem. If I start it on
battery alone then there is no drive activity but the caps, num and
scroll lock lights all flash. If I start it on AC then the capslock,
numlock and scoll lock lights stay on but now the power and charging
lights flash. I've tried disconnecting the RTC battery for a while to
see if that cures it, and I've taken the laptop apart and reseated the
power board and all the cables. None of these has cured it. I can't
get the FN+F11 combination do anything either. Does anyone know I
it's possible to tell if there is a hardware failure, perhaps the
power board, without having to take it for a service? If not, can you
recommend anyone near Edinburgh in Scotland with experience of these
laptops who can fix it for me?

 

please can you tell me what was the problemds, with your compaq armad
laptop and how did you fix it, I have the same exact problem, don'
know if it is worth repairing or not
