Hello, I have a 15 month old HP SpectreXT bought off Amazon. Over the past few months I have noted a dramatic decline in length of use on a full charge and have run battery test through the HP support assistant as well as through the start-up "esc" button method and both say the battery is fine...then the laptop shuts off at 50% charge. When charged 12 hours, it only gets to 74%-79% charge. I left the thing charging for 3 days and it only got up to 84% and then it says "plugged in not charging" when I mouse over the battery. Given that I can only get less than 2 hours use on a "full (3 day) charge" it seems the battery is obviously NOT "ok"...but I can't figure out what to do next to get my laptop to last a functional amount of time...3-4 hours with 50% screen and WIFI was probably the best i ever got, but 1-2 hours just doesnt cut it, when I charge it only 1 day, I might get 45 minutes...Very aggravating. Any ideas?
