Thinkpad T430 Flashing battery indicator, no power

Just a week ago my ThinkPad T430 had refused to start after I had swapped out a battery.

Just on battery power the laptop is completely powerless, holding the power does nothing, there is no indication of power as far as i can tell, nothing.

 

When plugging in, the only sign of light is the battery indicator, there isn't anything else. Holding to the power does nothing.

  • The battery LED pulses 2 short 1 long 1 short, stops and repeats.

 

What can I do to fix this? Do I need a new FRU (motherboard), can I replace the motherboard for one with dedicated graphics without compatibility issues?

Can soldering fix the issue?
