Hi, can anyone tell me whether,  vaio VGN-TX1HP/W and VGN-TX3HP/W motherboards are interchangeable??

My notebook suffered power surge due to loose power jack  and i would like to replace it with a higher model (same series) motherboard to replace my failed one.

Also, does VGN-TX3HP/W has 1.8" drive interface or standard 2.5"??/

All help is much appreciated..

Thanks
