[Solved] ACPI Battery State Unknown

Hi, I'm having some issues with charging my Lenovo V130 laptop. When I plug in it doesn't charge.

$ acpi
Battery 0: Unknown, 94%

Here is another status for my batttery

$ sudo tlp-stat -b
--- TLP 1.2.2 --------------------------------------------

+++ Battery Features: Charge Thresholds and Recalibrate
natacpi    = inactive (no kernel support)
tpacpi-bat = inactive (laptop not supported)
tp-smapi   = inactive (laptop not supported)

+++ Battery Status: BAT0
/sys/class/power_supply/BAT0/manufacturer                   = CPT-COS
/sys/class/power_supply/BAT0/model_name                     = L17C2PB3
/sys/class/power_supply/BAT0/cycle_count                    = (not supported)
/sys/class/power_supply/BAT0/energy_full_design             =  30630 [mWh]
/sys/class/power_supply/BAT0/energy_full                    =  31470 [mWh]
/sys/class/power_supply/BAT0/energy_now                     =  29800 [mWh]
/sys/class/power_supply/BAT0/power_now                      =      0 [mW]
/sys/class/power_supply/BAT0/status                         = Unknown (threshold effective)


Charge                                                      =   94.7 [%]
Capacity                                                    =  102.7 [%]

It was charging yesterday. I didn't attempt any changes on battery. I did powertop --calibrate and did some minor tweaks on tlp config 3-4 days ago but it was no problem.

Re: [Solved] ACPI Battery State Unknown

After some time discharging battery to ~70%, battery is back to normal and it is charging. Thank you guys.
