Yeah, tell me about it. I've been using my old laptop for 6 yrs now. The battery is completely broken now, and it's always on AC power. I had to use an SSD on it, due to its HDD failure which caused the loss of all my data. But other than that, it still is working, but only for trivial tasks, like downloading and stuff. I also replaced its broken DVD drive with a Caddy to add an extra HDD later. Oh, and there's now a bright spot on the monitor (IDK why)! This is obviously so messed up, but I figured it's "electrical" and not "mechanical", so I keep using it, esp. w/ Windows 10 which refreshed it! Although I really don't know what to do w/ the noise I hear from the motherboard (coil problem maybe.)
