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.
The battery is DC. How do you plan to provide DC to the battery connection from AC outlets without a convertor?
Using a DC power supply, I assume.
Okay but why go through the battery interface and not try the old converter cable one? Much easier to splice the cable past the box than try to rig a connection to the underside of the laptop. Would also prevent any ‘no battery’ issues too.
I’m pretty sure OP had that converter in mind when writing “[…] emulating it with a power supply with matching voltage […]”.
