1st gen ipad have charging symbol but percentage not rising
Hi , i have a 1st gen ipad which does not seem to be charging , i got some charge back into the battery ( about 30 %) using a bench psu , so i'm assuming battery is ok
I have been checking voltages around the board , ( ive included the schematic , page 17 , i couldnt save 1 page for some reason )
i have 4.2 volts at L1900 & L1950 .
Which line should be charger voltage back to the battery ?
Is this a good question?
