Two nights ago, I tried to shut down my HP Envy 15 m6-n113dx (I've only had it for about 3 months) which is running Windows 10. I thought that my laptop shut down because the screen was black but my power LED was still on and my fans were still running. I popped out and then popped in the battery but my computer turned back on with a black screen (power LED and fans were on). Tried holding down the power button but the laptop wouldn't shut off. I tried to launch BIOS and do a hard reset but it didn't work either. Whenever I plug in my AC adapter it just turns on with a black screen (power LED and fans were on). Please help because I don't wanna send it into the shop or open it up to void my warranty and HP customer support barely helped
