    the current problem i have on my HP TX2000 laptop is that the wifi switch stays in the amber color , and no matter how much i play with the switch , doesn't change . i tried to initiate the " diagnose & repair " on it , but it keeps saying that a " plug is disconnected " :( . does anyone know any quick tricks or have had this problem before and fixed it ???

    thanks in advance for any help :)

    Check the flat ribbon cable connection to the mainboard.

    i have it apart already and have cleaned the dust out , and checked all the wiring and made sure connector's were all in . i've been trying to figure out a way to get to the underside of the internals without having to completely take apart the tablet . do you know if the ribbon wires are underneath the board where the switch is ???? looking at it from the top side , i don't see any wires but there is one connector , it has about maybe 8-9 pins , that doesn't have anything connected to it , about a half inch from the wifi switch , but no wires or connectors anywhere that look like it belongs there

    What tx2000 model tabelt is this? If you have the nvidia graphics based version then the non functioning wifi is usually a symptom of faulty nvidia GPU's. If its the tx2500 then this issue could be for the most part ruled out.

    There is a fix:
    http://forum.notebookreview.com/showpost.php?p=4792475&postcount=15
    Read from that point forward in the thread. It's risky but effective. The tx2000 might use a thin thermal pad, in which case a copper penny is too thick for a shim. But reflowing the GPU and replacing that pad with a copper shim is the way to go.

    I just fixed the link, it had a stray ) tacked onto the end. Long story short, you take your notebook apart, use a heat gun on the defective chip to melt the broken solder inside the chip package, let it cool, replace the thermal pad with a copper shim (optional but highly recommended), put it all back together and hope for the best.
