The battery status toggles between not charging, not used, and unauthorized battery after it was calibrated using one key. Before that, the battery was working perfectly, lasting close to 5 hours. Now the laptop shuts off when unplugged and the battery status is constantly changing. I've had this laptop for approximately a year now and it was unused and left in an unopened box for the first 8 months.

Hi, Denkendale –
Thank you for writing in to the Lenovo Forum - happy to have you here today.
Do this test -
1) Switch off the laptop.
2) Disconnect power supply. Keep the battery connected.
3) Try to Turn ON the laptop.
If the laptop does not turn ON, the battery is faulty.
Also, Try turning the laptop off, removing the battery, unplug the AC adapter, press and hold the power button for thirty seconds, install the battery back into the laptop but don't connect the power cable and try to start the laptop on battery power.
Update us how it goes.
