Good afternoon, colleagues. I have a Lenovo ThinkPad S440 with the 1-3-3-1 beep sequence. I've seen videos about removing the memory because it won't connect properly, but that's not it. I don't know if the issue is with the internal memory, and I was wondering if anyone had a way to disable that memory and test if that's the case.
The power-up sequence is that when you turn it on, it makes those beeps, and the fan and the laptop turn off.
My suspicions are either the CPU or the internal memory. Has anyone had a computer with similar problems?
I'm adding information. I've seen that there are several sulfated components and others that are missing. I would need the schematic and boardview if anyone has it.
