My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?
Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?
My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -
Hi Guys,
I am seeking some assistance with a Dell Inspiron 3593 FD155 LA-J081P (REV 1.0) (A00) laptop
The laptop is working fine with the adapter plugged in and also with a charged battery.

ac adapter is listed as 'Not Installed'. So for instance, when a charged battery from another source
loses its charge, it stays on 0%.
Measurements taken
Charging IC (ISL95522HRZ) 32 pins
Voltage to ground with ac adapter only plugged in:

At startup of the laptop, the following error message is displayed by Dell SupportAssist: "Alert! The AC power adapter wattage and type cannot be determined. The battery may not charge. The system will adjust... -
Hi, i have problem with dell E7440, battery is not charging. Idk all story. Original Dell Adapter broken up (its not give 19V) i guess first ac adapter broken up and it broken charging circuit in laptop. Laptop has clone battery (Green Cell)
Laptop works on clone adapter, and its not charging battery. Like on photo. I checked mosfets near battery plug. They are not shorted. But on PQ809 and PQ810 are low on diode mode (both 0.25V) I desoldered them and check on bench and they are good both 0.5V on diode mode. I checked only drain - source way. So its board circuit it should be higher,... -
