I have a new e627 used only once before today. Battery connection was partially out and screen indicated low battery. After five minutes screen went black and now I cannot power up.

Ry to connect the AC adaptor of your laptop and plug it to the wall outlet and let it charge for 3 hours or more. When you plug it on the wall socket, it won't show the laptop's led blinking since it was totally drained. But after 3 minutes or more, it will start to show the blinking led to indicate charging. When blinking stops led light disappears, it is fully charged and ready to use.

Remember: Do not use your laptop while it is plugged in to save your battery life. When at home, remove the battery while it is fully charged and plug the AC adaptor directly to the wall outlet. It will still work without the battery as long as it is plugged directly to the wall socket.

Maybe your battery is totally drained.
