Less than year old laptop will not charge past 99%, randomly goes down to 0% and shuts off

[LR_15]

I bought this laptop less than a year ago and am having some issues with the battery.

I first noticed the laptop would not charge past 99% for a couple of days. Then, while using the laptop on battery it randomly went into hibernate as it usually does when it hits 10% only it never gave me a low battery warning and I'm fairly sure the battery didn't indicate a low charge in the first place. One of the times this happened I plugged it in to charge and within 20 minutes it had gone from a 2% charge to 99%. I unplugged it and used it on battery but after 2 hours of continuous use the battery had not dropped from 99%.

The most recent time this happened I had just turned my laptop on from sleeping overnight. I checked the charge and it was at 47% but I only managed to use the laptop for five minutes before it shut off, upon plugging it in and turning it back on and the battery indicated a 0% charge. With only 35 minutes of charging it had gone up to 99%. 

I don't know if my laptop just isn't reading the charge on the battery right or if there's something wrong with the battery itself but any help would be appreciated!
