Ever since I bought my laptop I never unplugged the AC adapter from my laptop, I've always kept it plugged in even when its fully charged. I didnt know I could use the laptop without it plugged in. Today I noticed after I unplug the adapter, the laptop wont turn on at all..It only turns on and there's power when the AC adapter is plugged in..the battery is inside the laptop so it's not just using the AC adapter. After plugging in the AC adapter and turn on the laptop, on the tray battery icon, it says it's 99% available complete plugged in,charging. Also, after I turn off my laptop, the orange light keeps blinking. I'm confused.
