Battery level stuck at 0%

Hello everyone, and sorry for my bad english.

I've installed Arch Linux a couple of days ago on my laptop (Toshiba Satellite L50-A-1EL). So far so good, the only problem is that the battery level showed is stuck at 0%, even when if it's fully charged. If I unplug the AC when the system is already booted, the battery normally works (and drains), but the level showed is always 0%; if, on the other hand, I unplug the AC while the laptop is off, and then I try to turn it on with the AC unplugged, the laptop reaches the Toshiba logo and then turns off, like if the battery is fully drained. I already tried to drain completely the battery to calibrate it, but it didn't solve the problem. I've also tried to install various power management tools, like acpid, tlp and xfce4-power-manager; they work, but they detect the battery level at 0% too.

Here's some console output:

# cat /sys/class/power_supply/BAT0/uevent
POWER_SUPPLY_NAME=BAT0
POWER_SUPPLY_STATUS=Charging
POWER_SUPPLY_PRESENT=1
POWER_SUPPLY_TECHNOLOGY=Li-ion
POWER_SUPPLY_CYCLE_COUNT=0
POWER_SUPPLY_VOLTAGE_MIN_DESIGN=15200000
POWER_SUPPLY_VOLTAGE_NOW=16084000
POWER_SUPPLY_POWER_NOW=23145000
POWER_SUPPLY_ENERGY_FULL_DESIGN=45300000
POWER_SUPPLY_ENERGY_FULL=0
POWER_SUPPLY_ENERGY_NOW=0
POWER_SUPPLY_CAPACITY=0
POWER_SUPPLY_CAPACITY_LEVEL=Critical
POWER_SUPPLY_MODEL_NAME=G71C000FP210
POWER_SUPPLY_MANUFACTURER=PEGA
POWER_SUPPLY_SERIAL_NUMBER= 

# acpi -i
Battery 0: Charging, 0%,  until charged
Battery 0: design capacity 2801 mAh, last full capacity 0 mAh = 0%

Any ideas?

Re: Battery level stuck at 0%

reaches the Toshiba logo and then turns off

does not sound like any SW issue, the battery probably really reports the zero capacity.
Since however the battery still works, it cannot be overdischarged.

How long can you run the notebook on a presumingly fully charged battery? How old is it, where did you get it and has it maybe encountered some "incident" (short, fire, trauma,…)?

Ceterum censeo: if there's a parallel windows installation, disable windows fastboot, https://wiki.archlinux.org/index.php/Du … t_Start-Up

Re: Battery level stuck at 0%

The notebook is indeed pretty old (around 5 years old), it never had any incident and I bought it new. The battery still works pretty good, it reaches around 3 hours or moreof screentime in Arch Linux (that's the time it took to drain the battery, with the screen always on but almost without actually using the computer) . I don't have Windows installed, but I had it before Arch Linux; the battery wasn't really good (around 1.5/2 hours of activity) but still, the level was showed properly.

Re: Battery level stuck at 0%

What bugs me is really the "reaches the Toshiba logo" because that's before any OS kicks in.

Anyway, what's the output of "lsmod"? There've been recent issues reg. thinkpad_acpi.

Re: Battery level stuck at 0%

Yeah, that's weird, because if the battery would be fully drained the computer doesn't even reach the Toshiba Logo. I should also add the at every boot, after the Toshiba Logo, "Checking media presence... No media present..." appears on the screen, like if the pc can't detect the OS or the Hard Drive (I should have specified this, my bad); after some seconds, anyway, the systemd menu appears and the OS boot up normally. Maybe this is the problem? I'll try to investigate. Anyway, here's the output of "lsmod":

Re: Battery level stuck at 0%

BIOS/UEFI update?
You probably also don't have /sys/class/power_supply/BAT1 ?
The thinkpad_acpi module isn't (accidentally) loaded, so dead end here.

Re: Battery level stuck at 0%

I think i've got similar problem.. but with thinkpad E580
After latest update and reboot it stopped detect of AC adapter plug/unplug.
thinkpad_acpi loaded

Tried ubuntu live cd, and it's working there

I don't have /sys/class/power_supply/BAT1 indeed, but I do have /sys/class/power_supply/BAT0. I will try an UEFI boot as soon as I can.

I should check if it works on Ubuntu too

downgrade of upower to 0.99.7-1 solved my issue with ac plug detect

Re: Battery level stuck at 0%

On Ubuntu Live the battery level isn't detected properly; at this point I don't think it's a problem of the OS. Even downgrading upower doesn't solve anything.

EDIT: I tried to update the BIOS using FreeDOS, but Toshiba provides only one executable that needs Win32 to run.
