Re: acer aspire V3 771G VA70
these are the voltages on U8800 BQ24725:
pin 1 = 19v
pin 2 = 19v
pin 3 = 19v
pin 4 = 25v
pin 5 = 3.2v
pin 6 = 2.6v
pin 7 = 0v
pin 8 = 3.2v
pin 9 = 3.2v
pin 10 = 3.0v
pin 11 = 3.2v
pin 12 = 3.2v
pin 13 = 3.2v
pin 14 = gnd
pin 15 = 0v
pin 16 = 5.9v
pin 17 = 5.9v
pin 18 = 3.2v
pin 19 = 3.2v
pin 20 = 19v
on pin 20 of the kbc U3001 I measure 3.2v AC_IN_OCComment
