[Bug 363822] Re: battery design capacity is reported incorrecly
I have the same problem on a HP Compaq NX6110: the "design capacity" decreases every time, when I discharge the battery totally. But it never increases, so the actual value is 90mAh! I have no idea what the solution could be for us, but there is a solution for an MSI laptop: https://bugzilla.kernel.org/show_bug.cgi?id=11632 ** Bug watch added: Linux Kernel Bug Tracker #11632 http://bugzilla.kernel.org/show_bug.cgi?id=11632 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/363822 Title: battery design capacity is reported incorrecly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/acpi/+bug/363822/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

okay i see, it's just that in my case the battery also won't charge any further than the wrong value. at least that's what i can say from the discharge time. but i would really be good to recheck that stuff in windoze, but reinstalling and deleting again that's to much time. maybe i can find a matching HP machine with installed windoze somewhere for checking the battery values. -- battery design capacity is reported incorrecly https://bugs.launchpad.net/bugs/363822 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Unfortunately I also have just Ubuntu single boot on my nx9420, but I think that it is unlikely to be HW failure of battery controller chip - how would than battery managed to be able to last significantly more than specified by value from controller chip (shouldn't it also control charging of the battery and thus preventing it from charging to the full capacity - which is obviously not the case?)? -- battery design capacity is reported incorrecly https://bugs.launchpad.net/bugs/363822 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

i also got such a problem on my nc6400 and lucid. in my case the design capacity is just 1000 mAh. but i am not sure if this is a software thing, but rather a hardware failure such as that the battery controller chip is reporting wrong values to the notebook. to clarify this can someone check it if the values are reported correct with the vendor delivered operating system (Windoze)? i would do myself but i have a single boot machine. ** Changed in: acpi (Ubuntu) Status: New => Incomplete -- battery design capacity is reported incorrecly https://bugs.launchpad.net/bugs/363822 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 363822] Re: battery design capacity is reported incorrecly
After recent update to Ubuntu 10.04 I still experienced the same problem (at that time I had design capacity = last full capacity = 0.681 Ah). I also tried clean install of 10.04 but described behavior didn't change. This problem is more complicated by the fact that in 10.04 power manager no longer offers option "do nothing" when battery reaches critical level - instead I had to find exact registry key (/apps/gnome-power- manager/actions/critical_battery=nothing) with Gnome Configuration Editor to force my laptop not to suspend/hibernate after 10 minutes. Battery is older but still able to last around 50-60 minutes, so this is obviously problem in software detecting the correct capacity - it shouldn't be changing the battery "design capacity" value at all and it should change only "last full capacity" value. If there is some possibility to set the battery "design capacity" manually to the right value please let me know, it would be helpful. -- battery design capacity is reported incorrecly https://bugs.launchpad.net/bugs/363822 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Is there any chance that this bug will be resolved? It is especially annoying when I used my laptop on AC power for a while and my battery capacity now drooped to 1.380 Ah, which means about 30 min. of battery life and than inconvenient waiting for sudden shut down:(. -- battery design capacity is reported incorrecly https://bugs.launchpad.net/bugs/363822 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The same problem is with my HP Compaq nx9420. On new Ubuntu 9.10 (I upgraded recently) it behaves exactly in the same way as on Ubuntu 9.04, which I used before. The label on the battery reads ~4.8 Ah, but these are the last seen capacities, which I noticed over time: 2.802 Ah 2.600 Ah 2.380 Ah 2.177 Ah - 2.562 Ah 2.616 Ah 2.651 Ah It seems not to detect "design capacity" at all and instead it sets it to the same value as "last full capacity". When I let the battery to discharge to complete 0 (by disabling automatic hibernation in power manager) it decreases the capacity as can be seen from the first 4 capacity values. When I let the battery to discharge below the critical level but not to total 0 (the laptop usually works 15-30 more minutes after the critical warning) battery capacity goes up - last 3 capacity values. This indicates that the battery HW is OK (2.5 years old) only it's detected wrongly. I assume that capacity gets decreased when discharged to complete 0, because it doesn't save "last full capacity" correctly, when the battery gets empty and sudden shut down occurs. Don't know if this assumption is correct (I just deduced it from observing the battery behavior over time), but anyway I use simple workaround, which is to disable automatic hibernation in power manager and this enables the laptop to use all battery capacity. But the cost is of course sudden shut down, when the battery gets empty - maybe not so good for my HDD I guess:(. -- battery design capacity is reported incorrecly https://bugs.launchpad.net/bugs/363822 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
