Hi
laptop powers on and working normal when no battery is installed, but when battery (not RTC battery I mean) Installed weird process happens when I measure:
As I plug in DC Jack, BQ24753(Changed by new one) Working and there is oscillation on Gates and 11V produces just for a second, then stop and charge(amber) LED Blinking and MB not powers on, ACDRV Signal is ON and We have DCBATOUT. Charge FETs changed by new one, Where I must dig?

Are You tried plug another battery?

Yes Another Working Battery Tested.

Voltage on pin 5 BQ24753?

check PQ1/PQ2/PQ32.
