Screen not responsive, what do I do?

After holding the power switch for 40 seconds don't panic if it doesn't immediately reboot. Mine just took about 30 seconds before showing any signs of life. It's okay now.

I just had this problem too with my Kindle 3 (keyboard).

I forgot to close the window yesterday, and it got cold and the air was slightly damp while charging, so I thought I had completely broken it. I don't think anyone here mentioned that kind of condition in which it happened, but I thought I would - maybe it is a factor of why it happens and nobody thought about it.

Anyway, I had a standby-screen and holding down the power didn't do anything, and neither did anything else I did. So eventually, about to give up I actually found a solution mentioned nowhere else.

I just typed "reset" into the keyboard and hit OK - and it started to reboot!

(not the new-line button, but the one in the middle of the arrow keys)

I admit I didn't think it would work, it was just frustration which made me do it, but it worked :)

PS: I posted this on this thread earlier today - I hadn't realized it was a Kindle-2 thread at the time, as there were some other kindle-3 posts on there

I had the same problem. The only suggestion I found was to hold the power switch in the on position for 40 seconds then release. It did not fix mine but it won't hurt to try. I did contact help from the Amazon site and they had no suggestions. They did offer me reduced prices on both new and refurbished models. Looks like I am due for a replacement! Can't complain after 4 years of heavy usage. Good luck!
