A few things to try:
First remove the battery from the laptop plug in the power adapter and see if it powers up without the battery in. If this works there is a problem with the battery or the battery driver. If it works login go to device manager and disable the Microsoft ACPI-Compliant Control Method Battery. If battery works then it was the driver if still fails its a dead battery.
Try with just the battery it is probably dead though as its had no power to charge it.
Check if the power adapter has a light on it some have lights that indicate its receiving power. Also check if the lights on the laptop to say the battery is charging even though you indicated it isnt.
Let me know how you go or if you need further help.
