ericbsmith -- DON'T RMA YOUR n800 YET! Read on...

Woohoo! Same thing, different day. I'm glad I'm not the only one who has trouble with my finicky tablet. Last night I turned my fully charged n810 off and went to bed (not because I'm a massochist, just because I want to keep testing until I am sure what the problem is). In the morning, it would not turn on. After plugging it in to the AC power again it began to respond to the power button, lighting up the LED blue and showing the Nokia logo screen briefly, but then briefly showing the battery charging image, and then sitting in a mode where the backlight was on low but nothing was displayed. After trying the power button a few more times to no avail, the green charging LED indicator stopped. Now it is back in non-working mode again. It has been about 10 minutes since I started with it this morning. I just unplugged it from the power and plugged it back in again, and I will let it sit for a bit. Nothing after five more minutes, so I unplugged from AC and removed the battery. Replaced battery, and VOILA! It turned on with first press of the power button (no special spot, just right in the middle).

I am now convinced that the power button is physically fine, but as some have theorized before me: for some still unknown reason the system (on these effected units) almost always goes into an apathetic mode where it doesn't care what you do with the power button.

With the battery out, I noticed a "2005" stamp on the circuit board beneath... could other n810 owners please report back what their production date stamp says? If there were a small number of these produced in 2005, and a larger number produced in 2006 and 2007, perhaps the older units from 2005 are the units with this power issue. That is my current idea for narrowing down the possibilties here.

REMINDER: n810 OWNERS, please post what year is stamped on the your circuit board beneath the battery. Thanks in advance!
