Howdy all, having an issue with an old Acer Aspire 5515. I recently replaced the DC port on it, and everything was fine afterwards. It seemed to charge alright, turned on fine without the battery and everything, however I did notice the battery was dying/close to death, so I bought a replacement for it. So the replacement came yesterday, and at first everything seemed to work fine. This morning, however, I attempted to turn it on and...nothing, wouldn't get to the BIOs or anything, just a black screen. So I figured maybe it was the battery, so I took it out and tried turning it on with just the power supply and still nothing. I suspect it's the motherboard going bad, maybe I fucked up in replacing the DC port or something, but I'd like to be certain before I rip it apart.
