AN715-51 - System not recognizing battery

mcd1993

So I had this problem first time a few days ago. I was playing FH4 on ultra and out of nowhere the laptop switches off. It was plugged in, and I turned it back on again no problem - but then whenever I unplugged the laptop it would die immediately.

I did some searching and found this guy who had a similar problem with a Predator laptop:

I followed the steps he recommended, and carefully removed the battery cable from the motherboard, waited, and then re-inserted it. Hooray! Problem solved, the laptop worked even while it was unplugged. Fast forward to today, I boot up FH4, and again out of nowhere the laptop switches off. Back to square 1, the laptop now won't work again while it's unplugged. I can't keep opening up the laptop and removing the battery, is there any other solution for this or am I going to have to send my (3 month old) laptop for a repair already?
