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.
It depends on the laptop. My old Thinkpad had a removable battery, and it actually ran fine without the battery installed. My Surface Book 2 has a completely broken battery stuck at 0%, and there’s basically nothing I can do except run it off the wall plug until the batteries start expanding and prying apart the computer.
I mean, I believe in you. You technically CAN do something about that. It will probably break in the process though.
