OK this is a WTF moment my laptop display quit working so it got opened it up and reseated everything except the CMOS battery and it didn't work, so i opened it up again and in the proses i lost the original CMOS so a new one got stuck into the laptop and it works now! so did the new battery fix the issue and if so could a dead CMOS battery be the cause of the "dead" displays on some of the laptops that i repair at work?

You must have a sad, sad boring life if you hate on people harmlessly enjoying life with an animal costume.
Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

You are welcome.. For related interest.. I just got a desktop in that the guy had removed a third party graphics card from because it failed. He tried using the motherboard's onboard VGA but it would not boot, so he brought it in.
Of course, the BIOS was set on using the seperate card and had no fall-back setting to use the onboard if the seperate card was missing.
A BIOS (CMOS) reset did the trick.Comment

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.

Hello everyone,
Mark and model: ASUS X571
Symptoms: not turning on. There is only the LED battery indicator working. The owner of the laptop told me this problem arrived one week after having changed the battery. He then managed to power on the laptop only once, and then it never powered on again.
