My A30 battery was about 4 years old when I decided to have it refilled. I notices an asterisk next to the Full Charge Capacity reading under Battery Health. After getting the battery back with the new cells the asterisk was still there, and I never got the laptop to run for more than 20 minutes unplugged running Windows. But in safe mode the refilled battery was good for at lease 3 hours.
My guess is the asterink indicates the microprocesor in the battery pack is shot, but that's a guess since I found no documentation to that effect on the IBM/Lenovo site.
Can anyone verify my hunch?
By the way, the refill vendor refunded my money when I returned the battery to the.
