    Hi everyone,
    I just received a shock, when I touched my power adapter. It was extremely hot and I wasn't even able to hold it for more than a second, actually not even a second. I could barely touch it and I noticed the connecting wires seemed equally hot at the connections with the adapter. I have noticed the adapter getting hot, but never this hot, not in this laptop or any other laptop. It's just been a week of ownership. Anyone else experiencing something like this? I am assuming this is normal, although I can't get over the heat I experienced when I touched the adapter as it was just too hot. It was so hot that my instant reaction was to just unplug it fearing it might just blow. It seems I might have burnt my fingers a little and I am not exaggerating. People spend so much money on products thinking they are getting the best but then such things happen...it's a little disappointing.

    Keith.

    Keith.. two questions:-
    1. Were you using the Tablet AND charging at the same time?
    Doing this puts a lot of strain on power adaptors and if it is underrated it will become excessively hot.

    2. What power rating is your adaptor?
    Is it 65W?

    My adapter is 65 W as mine is the X61t, the 7764-cto model with the SXGA+. I used it as a tablet only for a few minutes, not for an extended period of time and yes, while I was using it as a tablet, it was charging too. But as I said, I used it as a tablet only for a few minutes. I still don't believe it was that hot. Do you think this is normal? Granted that I don't have much experience with tablets, but it doesn't seem right for a normal laptop either.

    Keith.

    The adaptor on my R1 can become hot enough to be uncomfortable to hold but burning your fingers in less than a second seems to be in a whole different league. I'd ask for a replacement.

    It may be faulty but I would like to hear from another user who has the 65W adapter.

    Personally I would use the 90W type as it has sufficient power to charge the battery AND power the Tablet at the same time.

    I have a 65w adapter for the X61t and it does get very hot to the touch, but that is only after a few hours of use with the ac adapter plugged in.

    Mine is also 65W and I've never noticed it get hot. After a few hours of charging/usage of the tablet, it'll get a bit warm, but whenever I go to unplug it, the adapter is usually cooler than the tablet itself lol

    I have the 65W and when charging and on the Ultra Base it barely even gets warm.

    Thank you for your inputs guys. I just want to make one thing clear that my adapter didn't get red hot (if i can use that terms for a black adapter) just after a few minutes of charging. Let me give you the whole picture:

    I was using it with the adapter for some hours and during one of those hours I used it as a tablet for a few minutes and then I went back to using it in the laptop mode. After using it in the laptop mode for a while and then when I unplugged it, it was very hot.

    @P8rson: I think everyone with an X61t has an adapter with 65W, isn't it? Is is possible to ask Lenovo for an adapter with more Wattage? If I said it got too hot they will just say it is normal.

    Keith.

    Yep, I had the EXACT same problem. Called lenovo, they sent me a new adapter in 2 days and it works fine. From your previous comment it sounds like you called them and they said its normal? The person I talked to said it was definitely a problem and immediately suggested shipping a new one. Also does your adapter make a buzzy sqeaky noise? I think those 2 problems are related so you can make an excuse for having that problem. ;)

    Edit: I would also like to know if there was an adapter with more wattage. :)
