What are the implications of running a laptop via the battery connector instead of the DC jack? (feddit.nl)

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.

I've seen battery to wall power conversions before. As long as you're feeding the laptop the power it expects from the battery, I don't think it will care.
