    I 've been using mine for 9 months so far. I faced weird issue recently. When I lock m80ta with a power button for a LONG time (more than say a couple of mins) my touch stop working but pen still works. In list of devices I see that some UI interface device got the '!' sign. This does not happen when I lock tablet for a short period of time, say 5-10sec and then unlock. The workaround which I found is deleting of a PEN device from the device list and hard reboot (long pressing of a power button and power up). This helps, but only till next 'long' sleep. Thus I have to shutdown and power on it each time. What may be the reason? software or hardware? thanks

    I would guess it is the same cable failure issue, but the only way to know for sure is to replace the cable and see if the problem goes away.

    Thanks OP! I just opened up my tablet, and tried to secure the two cables. We'll see if the pen stops responding in the future (fingers crossed).

    Just a warning to you all. A friend of mine recently attempted the fix, and, when trying to pull out the cable, the connector (opposite the motherboard) sheared right off of the PCB. As the poll above shows, the success rate is very high. This is only the second time I've heard about the tablet being damaged as a result of an attempted cable replacement out of probably hundreds successful fixes, but risks are involved any time you attempt a DIY fix.

    Thanks for the warning. It seems like the chance for causing damage is low, but it's a good warning that the chance of catastrophe is there.

    Yeah, that kind of thing can definitely happen. Back when I was all-Apple I did that to a tiny cable in my new i7 27" iMac. I was following the iFixIt instructions to replace the HD with a SSD and they happened not to mention or show this particular cable, so I pulled the LCD free thinking I was clear. And the connector ripped apart, part with the cable and part still on the board.

    Because I wasn't a cute young girl the Apple Store guy didn't look the other way about it being my fault (kidding, but not really--cute girls DO get better service like that at the Apple Store, and elsewhere... I should have hired one for an hour to take my iMac in for me). Motherboard replacement would have cost $1600 plus labor. I bought an external monitor instead. S-word happens. :eek:

    Well the friend is a cute girl, so maybe she will have better luck than you did =P

    Her case is a little better off than yours was though. Nothing broke that wasn't already broken anyway, and I think the warranty is expired, so sending it into Asus to fix wasn't much of an option (they probably would have charged more than the value of the tablet to fix it)... Still sucks though.

    Which solutions are you thinking of ? The board itself is free of damage and the pins are big enough to solder again with a flux pen (the cable directly or a few mm of the same kind of cable 1° solder to the broken connector then to the pins). The original connector is solder in oven, to much time consuming to disassembled it I thing. Maybe as a temporary solution, reattach the broken connector like that if the 2 plate at each side offer some resistant (or are gently tighten). Anyway, there is hope for a repare shop specialised in mother board.

    She no longer lives near me, so I wasn't thinking of any solutions, other than throwing my hands up in the air. She attempted to glue it back on, and (as expected), that didn't work =P

    The funny thing is we both have PhD's in electrical engineering (technically), but neither of us know much about this type of stuff. I've never soldered anything in my life. We both did research in upper atmospheric science for our thesis... Although, she has less of a good excuse, because her undergraduate degree was EE whereas mine were in physics and mathematics =P

    I'll pass your suggestion along though. Maybe she could pull it off =P
