Warning. Lengthy, detailed reply ahead:First of all, let me explain the usage of this notebook, so you all can judge for yourself, if the battery wear is reasonable or not (I'd say it's not).
Treatment has been fair and respectful. That means, handled like the fragile, delicate thing it is. Has seen no outdoors usage, or exposure to any inconvenient environments.
Since it first came out of the box in August's first days, it had only a couple months, if that long, of (standard, nothing odd) usage. After that, it spent the vast majority of the time at tech support, for multiple hardware issues that are apparently unrelated to the battery (two HDD failures. WD model they used for this notebook produced several faulty units. It's on its third HDD now, which, being a different brand and model, is safe it seems).
Yes, I'm talking months after months just spent at tech support. They gave me all kinds of trouble and lies. If I'm rich someday, I'll get involved with Acer just to SINK that pit of thieves and liars
After that time at tech support, it's spent all the time in my hands, turned off and neatly inside the box (I admit, I never took out the battery to
preserve it further). I'm not giving it any use. I am only trying to get it all primed and ready so I can get rid of it. I need the money back. Thus, I'm not using it really, just preparing it for resell. That means, full XP install over the original Vista, plus some normal software (Photoshop, Nero, Office...), and fine-tuning to the best of my knowledge. That's not heavy usage, it's just an afternoon of installing and setting up.
Obviously, I cannot in good conscience sell it, without this battery issue solved.
What this all comes down to is: The usage has been very small, all things considered. It should be doing better I think. Though I admit, I've learned a good deal about just how fickle and expendable these batteries can be, and their quick burn-outs.
So, in reply to
starjax's useful post...
1) Drain battery, no problem. Drained it pretty fast by letting it stay in the bios. Don't think it lasted 40 minutes even.
2) Plug in done. BIOS is horribly scarce in options. Lots of things I cannot do there. Absolutely nothing involving the batteries or energy settings.
3) Done.
4) Done.
5) Tried both Everest and NHC. Mobile meter seemed a bit too basic and required me to install Google Desktop along.
All info I present now, is provided by Everest, though NHC served to confirm it, in all cases.
Let me detail the steps I took, and the info output by Everest in every case:
A) When I turned it on after 30 minutes of charging while off (after the full discharge while in the BIOS), I got a battery charge of about 51%.
B) Now, after 15 minutes of being turned on, and charging from the AC still, with Everest and NHC running, with
ePower management still installed but not really working (the window opens up but presents no power schemes and ALL options are unavailable, thus, not working really)...

C) Later on. Not a lot of time passed, all I did was uninstall ePower, and reboot. Still charging from AC.

D) Only change now, is that it's running on batteries, so now the full and remaninig battery lifetime values are present, and not "unknown" anymore. Btw, is this normal and constant? That no software can really tell you the lifetime of the battery if the notebook's running on AC? It does sound like an inconvenient limit that could be surpassed...also note how full battery lifetime is a constant, permanent unknow, regardless of circumstances.

E) Now, following the helpful info on the first link provided by
starjax, I plugged it back to the AC, let it reach full charge, then, using the
batcal software provided on that link, unplugged the AC and caused a full,
fast discharge (that is, battery was intentionally consumed fast by batcal).
Batcal timed the whole process, and battery readings reached 0% after
41 minutes. It didn't turn off right then, showing that the readings weren't entirely realistic, but it finally ran out for real and powered off instantly, being truly without any energy to go on, at
45 minutes.After that, I plugged the AC but left the notebook off, and gave it not the 8 hours mentioned under the link's instructions, but 12. These are the Everest details I got after that...
Power Management Properties:

As you can see,
wear level increased from 12% to 22% in one go.F) Finally, this is the info when, right after, I unplug the AC and let it run on batteries.

All I did, supposedly included a real battery calibration. But it didn't fix things. It only showed how the prior info was slightly inaccurate about durations, and pretty inaccurate about wear level. I'm still within the same notoriously low battery lifetimes, for something with so little usage.
So, should I just assume the battery needs replacing?
IMPORTANT: I also got to check the temperatures during the whole process. As I've said before, the fan always seems to be working at its hardest. You can just feel it and hear it, by the hot wind, and how hot the case gets on the notebook's underside, right by where the fan is (I assume the CPU itself is around there).
Everest presents two significantly different temperatures:
CPU Diode and
CPU. NHC presents only CPU, but matches Everest on the results. Don't quite get the difference, so I'll refer to CPU diode and CPU as presented by the software.
Now,
CPU temperature, when the notebook is just on starts on
47 degrees Celsius (116 Fahrenheit). Then, under the simple usage I've been giving the notebook, to test it, it picks up until it gets to around
57C (134,6F), and stays around there for the duration of this simple usage. When it gets pushed hard by the
fast discharge through batcal (see
step E, above), it reaches
73C (163,4F), and stays around there for the duration of this hard usage.
On
CPU diode: Just starting,
57C (134,6F). Under simple usage as described above, picks up until around
65C (149F), and stays around there for the duration of this simple usage. When pushed hard, as described above, it reaches
80C (176F), and stays around there for the duration of this hard usage.
Now, I do know what to expect from CPU temperatures on a computer. I've underclocked, overclocked, worked with different manners of cooling, overheating issues, and so on and so forth.
It's safe to say
those temperatures are totally through the roof.My basic conclusions are these:
Battery's wearing down faster than it should, but apparently these things are unstable like that. Possible causes, beyond simple passage of time:
1) Not ever being taken off during long periods of no usage (under my possession at least. Tech support may have kept it with the battery out, though I wouldn't bet on it).
2) Exposure to high temperature and inefficient, high usage thanks to a CPU that keeps overworking, no matter the adjustments.
Also, the constantly low numbers on battery lifetime, which would be low even if we added it a 22% from the wear level, may be also due to the CPU constantly overworking.
Acer doesn't seem to provide any sort of BIOS and/or AMD CPU driver for the Aspire 5050 series, except for the one I already mentions, which reads "Athlon" in big letters. Should I try to install that one? This notebook has a Turion, I don't wanna try forcing an incorrect thing on it unless it's really necessary.
AMD's website provides a sort of multi-purpose, multi-model driver/BIOS/whatever download, that targets the Turion, and supposedly affects its usage and energy efficiency. I'll try that one for sure. About the one I mentioned above, the "Athlon" one, I'd rather get confirmation/encouragement from someone else, like one of you people.
In any case, I made a Ghost image of the whole drive before starting on all these tests, so if that "Athlon" driver makes the notebook go bonkers, I can just overwrite everything and have the system right back to the fully fresh, complete XP and software installs...
I hope someone else can make more sense of this than me. Thank you all for the help.
sarjax: Your post has at the very least, given me a bunch of info to better understand this whole deal. Thank you.
