Battery not calibrated, should replace?

Hi, I have a HP G61 laptop, product no. VR523EA #ABU.  I noticed for a long time now, that when I run only battery only, it was only lasting about 20 minutes before having to recharge.  Then it came down to about 10, and now as soon as I get a 12% left warning, the laptop stops immediately.

I used out them to check the battery and it says the battery is at 100% power, but is in need of calibration.  So I followed the instructions but it does not complete the calibration.  I continue to try again and try to calibrate, but I'm just going around in circles.  In the end, all he says is "contact HP".

97% of the time I used the power supply so I really do not understand why the battery has deteriorated so quickly. I use Windows 7 64-bit.  Laptop is used only for net surfing and e-mailing, maybe a few powerpoint files.  Any ideas what to do?

In addition, if I need to replace the battery, in doing so, I will lose everything on the phone?  He restore default values or keep current and data settings?

Thank you very much... Celine

There is no memory in the modern laptop batteries. This advice was good there, but not more than 12 years. Running the battery up and down allows the synchronization of battery Windows with the chip inside the battery Manager. It is simply the most accurate meter. It does not affect the health of cells. If they are dead or moribund there not that you can do. The cells seem just like the AA batteries and battery that see you as a piece of plastic on the outside is actually a series of these cells all wired with a smart chip (brain) control the battery and its reporting to the computer status. When you get the new one that you can consider using 100%, run it at 40-50% then it away from store when you need it. You need a battery that is compatible with your machine and you have three choices. Buy the right to HP. It's more expensive, but you are guaranteed to get a new battery strong. The second choice is to buy authentic HP from a dealer. EBay has dozens. It will be a little cheaper, but you run the risk of getting the older stock. Batteries lose power just laying around. If you buy from a battery seller on eBay with tens of thousands of comments, you probably will not have this problem. Finally, you can buy a 'knock-off' Chinese (in fact they are all manufactured in the far East) battery. Budgetbatteries.com seems to be to distribute this type of batteries, but we know not. If they were selling the product "geniune" they would say so. Also their prices seem not that good for me on those that they have actually listed on the site. Counterfeits are very cheap and can actually be very good; they use the last cells of battery, but I wonder how they make batteries (child labour?) and what is their quality control so I tend to avoid. Once again, eBay is full of them. You can say their batteries because they will say "compatible", but not "authentic." Batteries for real HP say HP on the label. Finally, HP guarantees only batteries a year, even with their extended warranties. Guarantees that you buy at the point of sale as Best Buy often cover the battery so if you have this type of warranty check it out.

  • Qosmio G10-133 - battery not detected after upgrading to Windows 7

    Hello, I hope someone can help my frustrations here.

    In recent weeks, I successfully upgraded my laptop to Windows 7, an increase of memory to 2 GB, bought new power cord for laptop, new battery and resolved all the issues that Windows 7 has cast on me. The laptop and runs like one dream other than a question that seems to have had worse.

    The laptop no longer recognizes the new battery. (battery with a cross through it and a photo of current) For about a week after installing the battery, this has worked fine but now does not detect everything. I don't have any errors in Device Manager and windows recognized the ACPI etc battery inputs and has no problem. I also loaded the package of Toshiba value added that Windows 7 has found for me but still nothing. Battery not charge even though sometimes the battery works for about 30 seconds to start up if the battery is back removed and implemented, then stops again (once Windows loaded) I tried many things like the disabling of the driver, reinstall battery etc, but nothing. I tried the iniitally of battery with Windows XP and worked well.

    I have also searched the web and saw that many other laptops with Windows 7 have had this problem, including Toshibas. Some say update the BIOS, but Toshiba have not released an upgrade from the original in 2004 (which is for WIn XP Media Center), and there is no settings in my BIOS for ACPI etc.

    In addition, I can not calibrate the battery because I can't do anything with it. I don't think it's a question though.

    If anyone has any ideas I would really appreciate it or all the links to the drivers etc.

    If this is sorted my laptop should last for 5 years!

    Thanks for reading this.

    Hello

    First of all, I doubt that many other laptops equipped with Windows 7 have this problem. I've never heard of this and normally charge the battery will not be controlled of the OS. It happens automatically and your battery will be charged if the AC/DC is plugged. If the OS doesn't affect it!

    To be honest, I also don t know why your battery isn't detected, but what happens if you turn off the laptop and let the AC/DC adapter plugged in for 24 hours? After that, it should be possible to work on the minute of the battery for 1 hour or more.

    If this isn't the case, it seems to be a hardware problem, maybe the battery doesn t work correctly and should be replaced. You should contact the retailer where you bought

  • Satellite U400-119 - battery not recognized

    Hello

    I just bought a laptop TOSHIBA Satellite U400-119. The operating system is Windows Vista Home basic.
    Before I turned on the laptop, I plugged on the CC adapter and let the batteries reload for 24 hours.

    However, after 24 hours, battery LED icon is orange and blinks (which means that the battery is low according to the user manual).
    When I tried to turn on the laptop without the adapter DC laptop computer did not respond. So I installed Vista while the laptop was still connected to the DC adapter.

    After installation, the Vista battery icon displays a red cross on the battery icon, which means that it is not recognized.
    This is a brand new laptop so I think the battery needs to be replaced, but I don't know.

    Someone at - it had a similar problem?
    Any sollutions to my problem?

    Thanks in advance!

    A display really interesting because one of my friends got the laptop U400 and a similar one issued what s happened too.
    Suddenly, the battery did not recognize I thought that it s a malfunction of the battery. But I was wrong.

    The solution is very easy.
    You must update the BIOS and this should help get rid you of this strange issue.
    My friend did the same thing and it worked!

    So check it out. Download the BIOS compatible and right and update!

    Good bye

  • Toshiba A300 PSAGCE battery not detected

    Hello everyone.

    I have a Toshiba Satellite A300 (PSAGCE) which worked well since I. Recently, he showed "battery not charging". I went to see what I could do and someone advised that I should update the BIOS. So, I went to the website of Toshiba and downloaded the update for my BIOS. I have install without problem. He now has the version 2.20. The problem of "battery not charging" had disappeared.

    I had a new problem: battery not detected!

    The battery worked well and he gave me 2 hours of normal use. Now, it is not "detected". I did everything I could think of. Do you have the BIOS reset (pressing on the WE / OFF button / stop for 30 seconds), I left it with the battery for a few days, etc...

    When I connect the battery, it shows an orange light for 5 seconds and he died later. I don't know what more I can do. I contacted Toshiba in my country without success. They have not yet responded to my email.

    Any ideas? I tried with another charger than computer shows the same.

    I have install as a program of "batterycare.net" and it shows that I have 1.40 hours of battery, but as soon as I remove the cable ca, the computer shuts down without power.

    I guess I won't be needing help... I flashed my BIOS with a lower version that I had (2.20 > 1.80) and now it does not start even upward.

    I'm kidding not things for good.

    Any changes to save it?

  • Satellite L500 - battery not charging

    I have a Satellite L500-13W. This was bought to the Portugal, it is not listed on the website of the United Kingdom.

    I have a problem with the battery. It will not charge although it will run when plugged in. I read on another blog that an update of the BIOS cured the problem on another model. I found an update on the Portuguese site, but I do not understand the language, especially when it comes to my laptop.

    I was wondering if anyone was aware of this problem and the cure and also suggest how I would go about updating the correct BIOS

    Hello

    First of all, you can download all the drivers on the European driver of Toshiba download page where everything is written in English:
    http://EU.computers.Toshiba-Europe.com > support & downloads > download drivers

    Here you can also search for your model, as far as I know Satellite L500-13W belongs to the PSLJ3E.

    More info on BIOS update: this update is a bit complicated because it could destroy your ROM module so before making the update, close all programs running also your antivirus and firewall, disconnect Internet and make sure that you are logged on as administrator. Do not stop the laptop during this procedure.

    If the BIOS update work doesn t it seems to be a malfunction of the equipment. Maybe your battery needs to be replaced

  • Real battery not attached! ?

    I have laptop Lenovo Z570 after my installation of drivers, I tried to install the software Center solution for the control of hardware device and system of Lenovo. I have solved all the problems, but there is always a message in the center of solution showing this real battery not attached. I checked the battery series and the number of piece and found it's prescribed parts that came with your laptop and user written in textbooks. What really is the problem, it is the true message please see the snapshot of the message.

    Note of the moderator; photo showing s/n, edited for the protection of its own

    If you're referring to this "Solution Center":

    http://support.Lenovo.com/en_US/product-and-parts/detail.page?docid=PD022501

    See under "supported systems": download page

    http://support.Lenovo.com/en_US/downloads/detail.page?&LegacyDocID=MIGR-73784

    Your Z570 is not supported for this software. Most of the functions will work on your system, but the battery report no not because you do not have the "Power Manager" in your Z570. I think that you have the software of "energy management".

    I have the Toolbox Lenovo's ThinkVantage (LTT) installed in my Y470 (Win 7). This software is also 'not supported' for my Y470. Really, it was created for the ThinkPads, but everything works, EXCEPT the "unloaded" because I do not have the installed "Power Manager". The error, "genuine battery not attached" isn't the truth and false. You should put your faith in the software of management of energy says.

    There is no "difficulty" to do this, because this software was not created for your 'Z' Ideapad series.

    I hope that this clears the problem for you. Be happy, if all the other "Solution Center" programs in your Z570.

    See you soon

  • Pavilion dv6-6026tx: battery not

    The battery on my laptop dv6-6026tx stopped to load, but windows still says "plugged in, charging" just the percentage remains that never was it when it is plugged in (currently at 15%, for the last 2 hours).

    If I unplug the charger, the battery will be discharged normally.

    If I take the battery while the computer is running, your laptop will stay on and he's supposed to run on the charger.

    I tried to recharge the laptop both while on and off and tried to start it is plugged and unplugged.

    Help?

    Run the HP battery health test in the HP Support Assistant. It will read the data in the farm as the number of cycles, like the odometer on a car and also the health of every cell. The most likely thing is that the battery needs to be replaced. They do not last forever.

  • How will I know when my PC battery needs to be replaced

    Windows Vista sp1 - Home Premium 32 bit IE 8 not networking

    How can I know when / if my PC battery needs to be replaced? Computer has been installed may 2008

    Hello.

    There is not a really good to this answer unless you notice that the battery life is much shorther immediately when you first purchased the machine.

    Computer manufactureres that batteries in laptops are parts that suffer from wear, to this effect, there is only a 1 year warranty on it, opposes the computer that may have 2 or 3 years warranty.

    When a battery is 3 years old, very often, it will be shown signs of wear as fast discharge and the computer to stop suddenly even if it is 10 to 30% remaining battery life. When these events occur, it is time to put in place a new battery.

    Because your computer is 2008, and I guess you have not replaced your battery since then, I would say it might be time to change, but if you experience any of the symptoms I described above, or that doesn't bother you, there is not no need to replace it yet.
