Inspiron 7568 2-in-1 shuts off on log-in and battery not holding charge.
My company has an Inspiron 7568 2-in-1 that was showing signs the battery was not changing, now it shuts off right after putting in a password to log in. When I start the computer, I get a message "Alert! The AC Adapter wattage and type cannot be determined. The Battery may not charge. This system will adjust the performance to match the power available." It seems all I can access is the BIOS. Please advise how I can fix this. The laptop is still under warranty.
