Long story short, my laptops DC input is no longer working. Yes, I’ve tested every aspect of the power supply. I even measured the motherboard input voltage, and it is being properly fed. I suspect a faulty DC-DC converter.
So, I had this idea of removing the battery permanently, and instead emulating it with a power supply with matching voltage. I don’t really need the battery anyway (I mostly use a laptop for the form factor).
In theory, the laptop will then think it’s running off of battery power. Permanently. Are there any consequences in terms of performance that could arise from this? Of course, the power settings will need to be adjusted, but beyond that I’m wondering if there’s a hardware aspect that I cannot control.
It can be done I’m sure. But it’s still a whole lot of work instead of just fixing the issue. He’ll have to remove battery, disassemble it to get the control module inside, where his new psu to that so it fools the computer, drill through the case to run his wires and secure it to not be pulled on, and throw it all back together.
