Dell Studio 1737 PP31L - LED error codes

[uberplasma]

I ordered a replacement main board for my Studio 1737, installed it and I get 4 orange then 1 green flash from the LED at power plug. The original board still works, I am using it to type this post. The new board lights the power switch, spins the DVD and HD for a second or two, no noticeable backlight activity and no LCD image either, and then goes into the flashing LED sequence. Put old board back in works as it should.
Anyone know what the 4 orange then green flashing means?
Cheers

try removing the battery and see if it do the same. looks like it is a battery not recognized problem or ac adapter not suit for the mainboard.
