Hi,

I had a similar problem while using my N900 with the in-car charger. I was using the N900 as a GPS and it failed half way through the journey with that well known dry-swallow noise and getting very hot indeed.
Luckly I could switch it on later on without loop-reboot but I've got another issue.
My keyboard started to mis-behave. The "upper-case" key, the letter "t", and left and right arrow keys no longer work. The letter "e" key while pressed produces "et". Is that "E.T." trying to phone home?
It feels like a joke but it is not funny at all!
I've tried to change this behaviour by trying different foreighn keyboards but still no joy. Changed the language, no joy. Flashed OS (thanks God the U key still behaves as U) but no joy.
The phone also "dies" at least once a day for no apparent reason, i.e., it swallows hard and deep and faints, going into deep sleep!
Any other suggestions appreciated. This is the first phone that dies on me so often and that I feel I cannot rely on in times of need.
I haven no guarantee as I've bought it in working order on ebay.
Thank you kindly.
