What do you need the laptop for? It is a large machine, and quite heavy looking at the specs, do you move it around? Could you use it as more of a desktop machine? Assuming you're not a heavy gamer, that will handle normal use with ease.
Update, on my Dell laptop the battery drained the same, due to the firmware. On boot, I did get an instant white screen warning me the charger was not recognised, with click to continue. This meant it wasn't using mains power. The battery drained so much, it was down to 4%, I managed to download the firmware updater but it didn't update as the battery was so low. I switched the laptop off, and left it connected. It did charge, but super slow. I left it for a few hours, then it was charged enough to run the firmware updater. I hope that isn't the case for you, but from what you have said I thought I would let you know what happened to me.
