I have a Inspiron 17R SE-7720. The battery is no longer charging, even when it is plugged in with the AC adapter that came with the laptop. The blue light on the plug is on when the adapter is plugged in. Unfortunately the battery is now completely dead, so I am no longer able to turn the laptop on. Before the battery died, I checked the BIOS and noted that it was not registering the AC adapter. Not sure where to go next with this issue. Any help is greatly appreciated, thanks.

Before the battery was totally dead (when I try to power up, power light comes on for 1 second and shuts down again), I checked the battery health and it stated it was fine. I'm unable to run any diagnostics now with the battery fully dead.
