Removing battery solved laptop not starting initially

My laptop wouldn't turn on this morning and there was no light indicating it was charging. I ended up removing the battery to see if this was the issue and the laptop turned on twice for me. So I assumed the issue was due to. A dead battery. I've had the laptop for 8 or so years.

I went away and came back a few hours later and now it won't start again. So now I'm confused at to what could be the cause.
