Re: Lenovo laptop, series 3000 Is 45% battery capacity sufficient to upgrade BIOS?

Old battery cannot be recharged beyond 45% capacity. BIOS upgrade requires battery and AC adapter. New battery will not charge without BIOS upgrade.

Troubleshoot battery


If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced. Rechargeable batteries will fail if stored in a discharged state for long periods.

Battery lenovo G570


Extend your life laptop battery:
1. LENOVO G570 Remove the battery from the computer and disconnect the power cord if you do not plan to use your laptop for more than two weeks. Because the battery will discharge during storage out of the computer, it must be recharged every three months to expand its capacity and cycle to avoid problems loading or autonomy in the future.

Lenovo x201, new battery, after 30-1 hour computer shuts down, no warning, not an issue when using AC power, original battery never had that issue


If this is a aftermarket battery that would explain your problem, they don't have the same specifications that the original has, and the power capacity is less, the only way to solve the problem is to replace it with a genuine rechargeable battery.
