Hi , I had an issues with a 5420 Latitude, it would not boot and I tracked it down to the pmic which I changed and now the device boots. Now the battery is not detected, I get 1 white and 4 amber flashes when battery connected. I tried two batteries, one was new, and the issue persists. Can anyone point me in the right direction please ?

Can have a reason that the communication does not work. Or that the battery voltage is not detected by the controller. I would check the communication and the voltage at the controller. -
Hi FriedFred, I have looked at this but I have no comparison and it seems that this is a schematic that is hard to come by. I have ordered a new isl and will test with a new component.Comment

Measure the voltage to ground of each pin on the battery connector. Post the measurements.Comment
