because the seller suggest this. When I put the new motherboard in my laptop it cannot boot up and turns on. Only the power led is on but nothing else happends. So I take out the bios battery and I put it back. So when I press the power button now the led blinks 3 times.

Is problem with my new motherboard because it is not the same version???My old is DEV E and the new is DEV D.
Please reply me soon to send the motherboard back and take my money back.
Thanks my friend.....
