A new laptop manufactured 4+ years ago and never used since then. It has an internal battery that was not detached during the whole storage time.
The battery cannot be charged even after official reset procedure (via pinhole at the bottom of the laptop, holding "Power On" button for some time etc.) and after being on charger for several hours. Windows reports that battery is present, but it's 0%, plugged in, not charging.
BatteryInfoView utility (and other similar diagnostic software) reports this:
Battery Name: AC14B3K
Manufacture Name: SANYO
Serial Number: 2699
Power State: Critical, AC Power
Current Capacity (in %): 0.0%
Full Charged Capacity: 51,051 mWh
Designed Capacity: 51,051 mWh
Battery Health: 100.0%
Voltage: 4,557 millivolts
Charge/Discharge Rate: 0 milliwatts
Chemistry: Lithium Ion
Low Battery Capacity (1): 2,787 mWh
Low Battery Capacity (2): 3,557 mWh
Number of charge/discharge cycles: 0
So, I assume the battery discharged so much that it cannot start charging for some reason.
Is there any way to refresh/revive the battery, so it starts charging? Or is it an irreversible degradation of cells and I need to get a new battery?
