Battery monitor on tray says "Laptop battery is fully charged" all the time

Bug Description

Binary package hint: gnome-power-manager

On Karmic, the battery monitor on the system tray says "Laptop battery is fully charged" all the time. However, when I click it, the drop-down entry would state the right battery charged percentage.

Also, even when my system is set to hibernate when the charge is critically low, it just shuts down when the battery charge runs out. Is this a connected issue or do I have to report another bug?

Hmm. Any fix? If not, any quick workaround? :)

Btw, the system recognizes that the battery is critical low. I'm using the default Ubuntu setting that only shows the battery icon when charging/discharging. This shows the icon when the battery is critically low, but it shows a fully charged battery icon.

Quite same problem on my HP Pavillion DV3550ev.
The problem comes with ubuntu 9.10 and not with 9.04.
If i disconnect the power cable from the computer the battery icon works good, but if i restart the computer or i switch on without the power cable the icon give to me:"the battery is fully charged", but if i clic on the battery it gives to me for example 23% and no idication regarding the discharge time.
Is the same for the video backlight that witout the power cable during reboot starts the computer with 100% of luminosity but if i plug the power cable and then disconnect it works good chainging the backlights from 100% to 60%.
So it seems that the gnome power manager doesn't start alone during a reboot (with battery) but only if you disconnect the power cable.
Best regards.

As a temporary solution you can change gnome-power-manager with kpowersave. It works flawlessly on my HP!

Allan, do you have the equivalent problem in Lucid, as shown in my screenshot? If so we should update the summary+description.

Hello MPT,

I'm not on lucid yet. I'll report when I upgrade.

Regards,
Allan

Confirm this running lucid of an hp dv3500ea really annoying because you also don't get a notification of the battery being low due to this and the laptop can just switch off during work.

I see this behaviour on a Dell Inspiron 1150 running Lucid.
The battery drains completely to the point of immediate power off.

Gnome power monitor in tray still reports AC online, and "Laptop battery is charged"
The problem I believe is causing this appears under the report for "Power Statistics".
If I switch to "AC Adapter", the figure for "Refreshed" can stretch to at least 6000 seconds.
I have seen the battery suddenly start to report correctly and see this counter reset to a figure
recording a recent check of power state.

The state information under /proc/acpi is always correct .

Please could somebody check if this behavior is still occurring under latest release included in Ubuntu Maverick? Thanks.

I have this problem on Ubuntu 10.04 LTS on a HP DV3500 laptop. The battery state is always on AC power if the laptop is booted on battery. If the laptop is booted on AC power and then the power cable removed, the battery state is fixed and it correctly shows the battery discharging.

This problem is unfortunate as it affects the rest of my power settings, for example the screen brightness does not go down when on battery and the laptop does not sleep when on battery as it always believes it is on AC power. (I have set it to never sleep when on AC power). It also means when battery reaches critical the machine pops off, instead of gracefully shutting down.

Any fixes workarounds please?
