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.

Why not replace the dc-dc converter? Seems like a much simpler fix.

I live in the middle of nowhere, so getting a new one with the right specs could take ages, same goes for the tools needed, as all I have is a crude soldering iron.

What I do have, however, is a place where I can get an adjustable power supply with the right voltage. They had to ship one in with enough wattage from a nearby warehouse, though, so they said they'd have it for me on Monday.

What I also have is ability to get a new laptop if all this goes wrong s9mehow, so I'm not that concerned.
