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... -

Any ideas? Screen is not too bright. -
Hi,
Could someone help trying to unlock this BIOS, seems that Dell have changed the layout of new Dell Pro 8FC8 bioses from checking HXD - 4000 bits do not need changing, only 2000.

Has anyone found a way to crack this extra layer of security Dell have implemented? Seems both HP and Dell have upped bios security to match Lenovo by implementing extra measures on a separate... -
I would like to share my experience about charging issues with Dell power supplies with the tech community. I am working on a Dell Inspiron 5590, Mainboard 18778-1 with charging problems. The device can be switched on and works so far, only the message appears at startup:
Alert! The AC power adapter wattage and Type cannot be determined. The battery may not change. The System will adjust the performace to match the power available.
The power supply unit is not recognized in the Bios and the charging process is set to "idle". I use original Dell battery, type... -
A couple of days ago I finally got my hands on a locally sourced Trinitron and after lugging all 175 LBS home I gave it a good cleaning inside and out. The guy said it had been in a shed for 2 years, but the outside wasn't too bad. The inside was another story and while there was no evidence of mouse, it had certainly been kept in a VERY dirty home.
I cleaned it to an acceptable level of grime, at least clean enough to where nothing would heat up from the dust insulation. I then tried it out and it worked!
I'd say I had it on for about 15 minutes or so and then lugged...
