Does anyone know how to fix this?Įdit: after leaving the laptop on AC power attempting to charge the battery I've booted Windows again. I tried another AC plug, plugging the battery in and out and rebooting Windows without any effect. Furthermore, the device manager shows two devices in the battery section: 1) battery that complies to Microsoft ACPI-method 2) Microsoft AC-adapter. I've installed all windows updates and the device manager shows one device without driver called "SM-buscontroller" (hopefully this is the same name as in English?). The power led is blinking amber, which means according to the manual that "The battery has a charge of 20% or less and the AC power adapter is connected to the computer."
It says "0% available (on power, battery is not charging)" (translated). I've installed Windows 10 on the laptop now and suddenly the battery is not recognized anymore. It came with Windows 8.1 pre-installed with the battery working fine. I have a brand new Lenovo B50-80 since this week.
