Hello N770 friends,

My N770 has now Alzheimer's disease and feels just happy with OS2005.

I have OS2006 installed on my N770 and it was nearly allways connected
to the powwer supply. (over the last two years)
Today i noticed that i got WLAN connection problems and then that the
Akku was loosing power faster than normal.

I bought me a new Akku but that has changed little.
The Akku can now be full loaded but the device has still a power leak.

After lots of tests i found out that OS2005 works well.
No abnormal power lost and well WLAN funktion as normal.

Nokia_770_SE2005_5_2006_13_7.bin (good)
SU-18_2006SE_2.2006.39-14_PR_F5_MR0_ARM.bin (bad but once ok)
SU-18_2006SE_3.2006.49-2_PR_F5_MR0_ARM.bin (bad)

SU-18_2007HACKER_4.2008.7-1_PR_F5_MR0_ARM.bin (bad)

I am testing a  hacked version (which looks realy good by the way)
but WLAN doesn't work.
I was hopping that old bugs were fixed:

Over the top buttons (+ and -) i can measure a temperature of more  
than 35C and on the right side of the device
30C, when the device is switched off. (30C is nearly room 	 
temperature - hottest part on a active N810 is here 32C)

1.	is virtual memory essential for versions above OS2006 ?
	(to reduce error sources i have taken out the mmc card )
2. 	selfdiagnostic tools ?
	(would be nice to have a hardware diagnostic beside the boot flasher  
on the devices !)
3.     could be done something wrong during flashing that is not  
obviously  ?
4.     any suggestions are welcome :-) ?

happy summer :-)
