I'm about to go off to college, and need to be able to use my laptop without having to plug it in. I ordered a new battery for it, and just got it in the mail today. I put it in with the laptop on, and my laptop identified it, saying it was at 74% charge, and charging.
But as soon as I unplugged my laptop from AC power, it shut off. I left it plugged in for a while, restarted it, gave the battery a few minutes to charge, and looked at the battery life only to see it was still at 74%. I tried doing a battery calibration through the BIOS, but I don't see any "Power Options" in it, and though I have the files to do so, I don't know how to update my BIOS and don't want to rick messing anything up, especially since I'm not sure it will even fix the problem. Can anyone help me with this?
