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... -
Hello,
after seraching a long time i not can find a schematic or boardview for the DELL Optiplex 5070 SFF. gen 8/9 CPU
The numbers on the mainboard i found and searched for are:
Dell P/N

Hi,
I have a Dell XPS 9300 that's working perfectly fine with an external display plugged, from windows the internal display isn't detected. At boot I can see the Dell logo then when it should display the boot/bios or whatever the screen goes black (no backlight, no image using a flashlight). I tried unplugging everything on the motherboard except the eDP cable but it didn't helped (so it's not the lid sensor). LCDVDD/backlight power are powered down when this happen, PANEL_BKEN_EC and ENVDD_PCH are also down to 0v. It's weird, it almost feels like the motherboard is shutting down the display...
