seering comes from power source, aka "charger"

nope not the charger, from my n900.. i'll check and see if disabling R&D mode works, can't remember enabling it though.

yup that worked.. i believe i enabled it because i was intending on mucking around with it.. so what do the flashing keyboard LED's tell me then, that it's in R&D mode or is it feedback of some sort?

okay the flashing keyboard lights have stooped after disabling R&D mode, but the searing sound has not stopped.. it's almost the same kind of sound the old school flashes made when loading.. except it sounds broken ... almost like small little bubbles bubbling in water, like when you look for a puncture in a tire under water, that's exactly what it sounds like actually.. anybody else had this?

"N900: The keyboard backlight behind the left and right side of the keyboard flickers in response to system activity."
From http://wiki.maemo.org/R&D_mode
Not sure about the sound though, could need a repair by Nokia.
