So my laptop wouldn’t boot tried new external batteries nothing, new charger nothing and different breaker in my house nothing. I was exploring the internet when I came a crossed an article talking about CMOS batteries. I read it and learned that the CMOS is attached usually to the motherboard and is responsible for running bios and booting the laptop. If you need to find it you can’t miss it, it looks kind of like a watch battery in a plastic socket. Anyway I swapped it and my laptop is back to normal. Hopefully this helps anyone with the same issues. It’s worth a shot if you don’t hear any mechanical noises, the caps lock flashes, pc won’t boot or you get battery error 601 I had all these symptoms when my computer malfunctioned. Good luck to all who are having computer trouble.
