Hi, not sure this has been reported before. I have my n770 for a couple of months now. Just a week ago, I started to notice the top portion of the frame, around the power button, was bit too warm (hot) in both "Charge" and "ON" modes. At least it seems hotter than before. I further found the battery would not last for more than 10-15mints after charge. Any ideas? I bought it from buy.com and I guess there is little chance Nokia would honor their warranty.

Thought to properly close this ...

I sent back the faulty unit through UPS. Never got any receipt acknowledgment from them after UPS's delivery confirmation for 2 weeks. Phone calls and e-mails many times, and they never went anywhere.

At the time I was about to give it all up, there comes a US post service parcel with a replacement unit from Nokia with a note saying the original unit could not be repaired.

Anyhow, the end of story.

Oh, there are two hot pixels on the new unit, well ...

I have this same issue on an N770 that is about 10 months old. I thought it was a bad process, so I installed a cpu monitor, but even with low CPU load, the thing heats up at random and drains the battery. Any ideas before I send it back to expansys? thanks

Update after some fault isolation: this seems only to happen at work (where I use bt, but not wifi).

Is it plausible that there is noise, or jabbering, in the bt or wifi spectrum that is causing induction, or chatter? On current form, if I send the thing back, Nokia not going to be able to reproduce this problem... rrggg
