Have looked through the forum, I did not find anything related.

I bougth my T520 in April in the United States. It has a battery 6-cell 55 ++. Its capacity should be 57Wh 10.8V (this is what is written on it), but my reports Power Manager only 47.7Wh and it has been like this since I bought it.

design fees: 47.52 Wh

design voltage: 10.8 V

Full charge: 47,70 Wh

Other fees: 47,70 Wh

voltage: 12.21 V

FRU part number: 42T 4791

Serial number: 22793

Number of cycles: 7

Bar code number: 1ZHFH13JLXP

I paid and charged twice already and nothing has changed.

Also it can reach 4 hours on battery.

  • Qosmio X 770 battery capacity

    Battery on my new X 770-107 a condition of 36% out of the box, lasting 45 minutes or less.
    I had been replaced by another in the authorized service center. The next day, having a new battery wear level of 17%. Obviously, something is wrong with batteries in this notebook or applications with which I tried to test it are bug (BatMon, battery Eater...).

    I want to make a comparison.
    Could someone post the maximum battery capacity and level of wear using BatMon (or another application)?

    I called today on the limitation of emissions and the instant battery of 21% on the box.

    It is perhaps false readings of chip set API to reading the other post.

    However, these two issues have been promised escalation and a response until my return rights are on the rise.

    If all goes well they will address this forum directly?

  • Satellite A100-19: battery capacity lower when using Vista

    It is my another problem with Vista Ultimate after using XP. Before installing Vista (I mean using XP), my battery capacity is almost 2 hours but after installation of Vista, the capacity fell suddenly. After fully charging, when I plug in the adapter, the battery shows 44 minutes remaining understood fully charged.

    I would also like to add that this 44 minutes is seen in the energy saving mode and brightness is at the minimum level.
    What can be the problem? My battery is dead?

    Do I need a new battery?

    Hello Alain

    read the various PC magazines, last 12 months, I found a lot, but really a lot, articles on Vista and all of the issues using the Vista operating system. All those who wrote all that was unique in one thing: Vista needs much more resources than Windows XP Home edition and you shouldn't be surprised with your discovery.

    Sorry I don't have any other comment. Maybe you should take more time and pick up info on Vista read different magazines PC or simply Googling autour.

  • iPhone 6s more battery capacity < 90% after 4 months

    If the image below got me concerned enough to my phone. My battery capacity has fallen by 10% over the past 4 months, that would mean in the next four months, I'll be below the 80% that Apple sets for a track of 2 years. Should I pop to the store right now to get the snippet or they will decrease just my complaint?

    Other people with the same problem?

    First of all, where do you have this image of the screen of?  I wonder about the accuracy of the information.

    In any case use the iPhone until it automatically stops.  Ignore any alerts that may appear.  Then charge it overnight using the charger and cable provided with the iPhone.  Finally, check your ability.

  • Unable to determine the battery capacity

    Hey guyz m not able to detect the device battery capacity according to the (documentatiom)

    For my Volt application, I use battery.h BPS, there is battery_info_get_battery_full_charge_capacity(), but you should not trust this value based on my experience, it always points to 80000, which is the value for BATTERY_INVALID_VALUE. Instead, use battery_info_get_battery_design_capacity() but be warn that it will return the size of the normal battery for the device. So, for a Z10 with an oversized 3800mAh battery, it will return 1800 (size of battery default Z10).

  • Portege Z930 - high loss of battery capacity

    I have the laptop since July, 2013. At the beginning I had good battery life, the battery has a duration of 6 hours, which, with the time declined to something, like 4 hours.
    Now, I have been using the laptop plugged in for a while, and found out last week that I have a huge capacity loss, about 55%. The strange thing is that it's much worse in a few days, and now the loss is 77%.

    In addition to buying a new battery (which I'll do in the future - btw, a tutorial on how to change it?), what can I do? This capacity loss is permanent? I've been measured it with a tool of acpi.

    Thank you
    Jose

    Since the last post, the loss of high at 83 percent capacity. Any idea?

  • Drop sudden battery capacity T430s

    Hello

    I have an eye to my stack report today and found something really awkward. I bought the computer seven months ago and the beginning of the battery with the theoretical capacity 44, 000wWh, while the load capacity full is much closer to the rated capacity. However, in the report of battery it shows that two weeks ago the nominal capacity suddenly drops of 44000 to 40734mWh in a week, then later it drops to 39000mWh. And the actual full load capacity seems to linger around 37000mWh. Y at - there is something wrong or my battery just wear out naturally?

    Best,

    Eddy

    Run a battery to reset the power manager. 7 months is late for a reset of the gauge.

  • End 2011 13 "MacBook Pro battery capacity

    I noticed the battery on my end 2011 13 "MacBook Pro does not seem to hold charge for a long time, I can take the machine off and he will die in about 90 minutes of light use from 100 to less than 10%

    I tried a full cycle of discharge and recharge and checked the number of cycle in the details of the system (screenshot below):

    Any ideas why the battery loses capacity so quickly? I'm not under all the apps that are starved for power and it drains quite quickly sleep when disconnected from the power supply.

    It is certainly far maximum cycles count > https://support.apple.com/en-us/HT201585

    Just in case where, exit all open Applications before you put the Mac to sleep to see if that makes a difference.

  • Report battery level

    Virtually every application/widget I've tried don't give me a report on the level of the battery in 10% increments. Is it possible for me to get a more accurate report on the level of the battery?

    I use the Circle battery Widget. It works very well. Thus, it seems very accurate. It will show you even if the phone is charging.

    In my view, there are others on the market, but it's the only one I know. I hope this helps.

    How will you measure that? Apple does not battery management API expose in their software development kits, if you use a third-party application, so it is likely inaccurate. If you feel that your battery life is shorted than before, first follow these tips:

  • 15 au091-nr: computer HP laptop with good behaviour battery won't start.

    This is so the layout down, last night, I decided to play some (Minecraft modpack) Hexxit for about 5 hours. He was about 21:30 and had to go to bed, so I CTRL ALT DEL and clicking shut down. Forward to the next morning, I finished getting ready for school and take my laptop to check my mails as I do every day.  I open the cover and press the button power, slowly, realizing that something is wrong. I don't hear any fan from, but the power light turns on and is so light that recognizes the PC workload. I gave him a hard reset which did nothing. The battery is unremoveable so I can't reset it by these standards and if I try to do, my warranty will be void, which foreshadows the fact that I got this phone recently (one week to be exact). I realized that something was off because when you start a laptop computer, the fan will kick for a few seconds then die down until the PC Gets a task. If you people need more information just ask me, I'll be online I hope to have a working solution.

    Well, I went back to the Pavilion and I decided to go with an Asus laptop, where it won't break on me on the 12th day. HP is slowly dying anyway. Screw them.

  • When the capacity of the battery falls Satellite Pro U300 occasionally lose power

    Hello

    I suspect you have a defective battery (standard installed on the laptop) on my new Satellite Pro U300 - 11 k and I wonder if someone had a similar problem.
    When the power drops to 10%, my laptop occasionally loses power. In the range of less than 7% capacity always loses power, i.e. either fails to start the hibernation, or is unable to complete the process (I can always tell if power was lost during hibernation because of the characteristic of the system of protection HD sound). I did several tests, especially in the power saving mode. "High performance" mode power seems to be a little more reliable, but still fails to shut down less than 5% of the capacity. The level of Hibernate by default on the Toshiba Windows Vista pack is as low as 2%, so I can wait until it is able to work at this level.

    Overall the battery capacity is about 1 h (Media Player, fashion high performance, maximum intensity) at all about 2 to 2.5 hours (slowed or text editor, mode, brightness low power saving). Charging time is about 1 hour (seems too short). They are difficult to objectively assess that Toshiba avoids quoting the specifications of the battery, but I consider the question of the reliability of the above as being a serious (do not want to take the risk of damaging the HD). I am considering visiting the service center, but leaving both the computer and the battery with them would be a nuisance for me and I would rather avoid it if I can. I wonder if I can claim the warranty on the battery alone?

    Any suggestions would be welcome.

    Background information:
    -The U300 is a few weeks old.
    -The battery has been fully charged and discharged (approximately 15 times since purchase).
    -Cooldown takes 1 h - 1.5hrs
    -J' using Vista Business
    -J' went through the power settings to make sure they are ok and to change threshold levels
    -I am an experienced business user, I use a laptop computer at work which stops always perfectly to the power level of 3%

    Thanks for help

    Hello

    Reading your post, I do see no battery issues! Everything you say is right and not a malfunction.
    Please note that the Vista operating system needs much more computing resources and the battery is much more emphasized running Vista!

    Please also note that the level and time to discharge the battery can be different! Everything depands of the use of the laptop!
    All the portable devices and parts waste the power of the battery at the same time and that's why there are differences in the discharge procedure.

    Don t be afraid and take advantage of your laptop but if you think you will need to contact the ASP in order to clarify this issue, then feel free to contact service technician.
    They should be able to help you.

    Good bye

  • Replacement battery high capacity NB305 - PA3734U-1BRS

    Another question relates to one of my previous related post.

    It seems a good replacement battery high potential capacity for my NB305 PA3734U-1BRS.

    My question is:

    Someone at - he bought one of these and if so, is is much better / it lasts longer than the original battery?

    Thanks in advance

    Hello

    I think you are talking about this battery:
    http://us.Toshiba.com/accessory/PA3734U-1BRS/

    Mentioned here, its that the battery would go up to 9 hours in Normal Mode
    But I have to say that the working time of battery depends always on notebook use, this means that the brightness of the upper display, HDD high run time or high-performance CPU and GPU would decrease the battery considerably working time.
