laptop shows battery charge is at 100%. when I unplug the ac power the laptop immediately shuts down even with new ifixit battery. ive tried several different ways to reset it. looking for more suggestions.
Hi, Just to verify that the battery is OK, create a battery report to check it status. Compare the Design Capacity value against the Full Charge Capacity value. With a good battery they should be nearly the same. Does it do this if you reconnect the old battery again?
