My laptop’s battery kept getting worse and worse. Eventually it couldn’t keep a charge. Laptop would still run on AC power but it would randomly power off abruptly. I changed the battery. Powered up and it seemed ok. It said that it was charging. At one point it reached 100%. I kept it plugged in in order to calibrate the new battery. Then the original issues returned. I’ve also gotten messages that it doesn’t recognize my charger even though it’s the official one that came with my laptop. I updated everything and it happened again. Now it will not start for more than a second. There’s a blinking orange light near the trackpad but doesn’t blink a consistent amount of times. Any info is welcome. Thank you!
