Question Battery's energy when full is way more than energy (design)


Hi,

I'm writing about my packard bell laptop (dot M/U, model number ZH7), on which I am running Ubuntu 12.04. For some time now, I held its battery for dead, but since it works fine with the AC power plugged in, I didn't pay too much attention to it (I had other projects to look after). Now I wanted to finally find out if I should get a new battery, and what's up with the old one. I checked the power statistics, and I realised it won't charge beyond 3%.....of its 'energy when full', or 30% of its 'energy (design)' (??!!!?). In particular the power statistics show the following:

Quote:
native-path: /sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0A:00/power_supply/BAT1
vendor: SIMPLO
model: UM09E71
serial: 0027
power supply: yes
updated: Mon 15 Sep 2014 10:07:38 CEST (7 seconds ago)
has history: yes
has statistics: yes
battery
present: yes
rechargeable: yes
state: charging
energy: 19.0809 Wh
energy-empty: 0 Wh
energy-full: 584.659 Wh
energy-full-design: 48.84 Wh

energy-rate: 1.24753 W
voltage: 11.434 V
percentage: 3.26359%
capacity: 100%
technology: lithium-ion
What surprises me is that "energy-full" is so much more than "energy-full-design". In all the questions about battery problems I have seen so far, this was never the case, and these values where either equal or the "energy-full" was less than "energy-full-design". What is going on here?

The laptop powers off instantly when I unplug the AC power, and I have tried taking the battery out and putting it in carefully again.

when I type
Code:
acpi -b
it gives me:
Quote:
Battery 0: Unknown, 3%
I have tried installing powertop and running it with the autotune option:
Code:
sudo powertop --auto-tune
The overview says:

The reason I say strangely is that yesterday I clicked on all the items that said "Bad", which turned them into "Good", apart from the first one which wouldn't change. Today that I ran it again to copy paste the output here, they all returned back to "Bad".

I am a newbie and I have no idea what all this means, and how come my Energy (full) is so much more than my Energy (design). The battery won't charge beyond this "3%", no matter how long I leave it plugged in and shut down.

Any help would be greatly appreciated!

Oh oh? Right before I wrote the above, i installed acpi, since
Quote:
sudo acpi -b
wasn't recognised, and it was given as an output to other battery related questions I found online. After I posted the above, I restarted, updated and upgraded (though that didn't add anything) and now my battery on the top right of my desktop is marked as "not present"!!!!!! But when I go to power settings it gives me its specifications...? In particular, typing
Code:
 upower -i /org/freedesktop/UPower/devices/battery_BAT1
in my terminal, now gives me:

I'm confused...

The odds are that your battery is kaput. Stuff wears out.

I recently started up a five-or-so year old Dell laptop on battery power (it's usually on AC) and GKrellM told me my battery was at 133%. Five minutes later it was on 88%.

Since that was the computer I usually take to my LUG meetings, I ordered a new battery from Dell, after reading the reviews of after-market batteries.
