After using the Nokia 770 ( SU-18_2007HACKER_4.2008.7-1_PR_F5_MR0_ARM installed ) a heck of a lot ( to the point that even after repeated starts the machine shut off by itself more than twice ) I put it to charge at 8.30 AM in the morning.

In the beginning the Nokia AC adapter got rather warm but then it got to normal room temperature. Nokia 770 showed that it was " Charging ' (vide the charging icon seen on the screen).

This icon stayed on the screen till about 4.30 PM the same day at which time the screen showed " Battery Full " icon. During this whole time period the Nokia 770 was not on , used or the AC adapter disconnected from the Power even once.
