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.

      oh neat, there’s a new standard that pushes up to 240W

        though laptops are notorious for proprietary charging.

        I’ve seen dells that can charge via USBc at full 140w but only on a Dell dock. On any USB PD charger it will only do 60w, and complains about it as it throttles everything.
