Hi, I got E7240 after water damage.
After cleaning laptop starts normally but is not recognize adapter (genuine one) and not detecting battery also (LAptop can work on battery but will not charge it)
It can work on adapter alone and with battery but is not recognized. I checked middle pin and 3.2V is present.
I tracked NB_PSID up to U38 chip pin A55 and there is 3.2V, I removed U38 cleared all pads and still this same with no change.
Please some1 help me where I can look for reason of this faults.
Many thanks
