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.
If it’s from the last few years and the barrel input has an adjacent usb-c port it may accept usb power delivery
The port may not even be labeled for it
It just so happens that there’s a USB-C close to ir, but I think that’s just a coincidence as this laptop eats a lot more than even the beefier USB chargers. 20V, 14A. Some sort of square 4 pin connector I haven’t seen elsewhere.
ouch, usb c caps out at 100W afaik
The standard is up to 240w now
