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.

A lot of laptops still have a coin cell

Really? My laptop doesn't. Maybe it depends on if the battery is designed to be removed by customer or if it is hidden inside the laptop, making it accessible only with tools.

that's more likely the deciding factor yeah
that and whether or not you're me. I always seem to have the bad luck that whatever model want to buy doesn't have a coin cell lol

Actually even a lot of laptops with non easily removable laptops still have coin cells. My work requires me to sometimes to repairs and I’m surprised by how common it still is
