Hello,
I have a Dell Vostro 5490 that is giving me an LED code indicating "Invalid memory installed."

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.

I have tried multiple different Dell power adapters. My Dell... -

Hi friends, I have a problem with this laptop. It gives me a processor error, but when I measure the processor, it has power, heats up, etc.
But at first I thought maybe it was the BIOS. I tried reprogramming it, but nothing.
After that, I measured the graphics card and realized that the graphics card has no power.
So I lifted the power coils and checked that there is power, but when it reaches the GPU, they go to ground.
With a thermal camera, I realized that it apparently has a short in a VRAM. After removing the short, it goes to the GPU.
So my question... -
Hello,
do you know how to disable onboard ram on this motherboard? I have 4 beeps after power button press. Or how to check which module can be broken and take off it from the board.
