Hey guys, I was wondering if maybe you can offer some advice. A couple weeks ago I was using my 4210 and all of a sudden it just shut off on me and would not turn back on. I sent it in for warranty repair at a place locally (authorized Fujitsu repair shop). Turns out the motherboard was fried and they had to order a new one. (my laptop is about 2 months old) Now that I've brought my lifebook home, I've noticed a couple things different: 1) The wireless on/off switch will not move anymore. I tried as hard as I could to shift it from the off position to the on position but it will NOT budge. The wireless and bluetooth are working though. So I'm assuming the technician installed the motherboard and did not connect the external wireless switch? 2) The wireless card is different. When I had ordered it, I had ordered the Intel wireless card with bluetooth. Now after the motherboard switch I have the atheros card (I know it's not a huge deal, but it's still not what I had initially ordered) 3) My battery life of the modular bay battery has significantly been reduced. I'm not sure. Before, my laptop had a monstrous battery life however now, it's battery life (especially of the mod bay batter) has been significanly been reduced. I'm weary to go back to that authorized fujitsu repair center. Would it be better for me to call Fujitsu directly and maybe send it in to them? This is so disappointing considering the laptop is only 2 months old.
