If you are not satisfied with the information provided, contact your mobile PC manufacturer. If you purchased the battery separately from the notebook computer, contact the manufacturer of the battery.

I've also included some tips on how to prolong the life of your battery

How to extend your battery life

The storage capacity of the battery will degrade over time, based on the use of your laptop. This degradation is normal for all rechargeable batteries. If you run your laptop on battery often, requiring one or more refills per day, the battery will degrade more quickly and requires a replacement more quickly than a battery that is used occasionally. Temperature and humidity influence the battery's storage capacity. Store the battery and the laptop somewhere cool and dry.

Under normal conditions, a battery should run well for more than a year, but it will retain less fresh whenever he reloads.

Tips to maximize the life of the battery:

  • Turn down the brightness of the screen.

  • Use the energy saver power Plan.

  • Buy another battery to limit the number of re-charge on a battery.

  • Remove the battery from the laptop when not in use.

  • Store your laptop somewhere cool and dry.

  • Do not charge the battery for more than 8 hours.

  • Remove the battery from the laptop when using current alternative to avoid the short charge and discharge cycles.

Note

  • When you store a battery for a long period of time, it must be stored in a cool, dry place with about 50% charge on the battery. A battery stored with little remaining load can completely discharge and not being able to be recharged.

  • Satellite C50-B-19V - RTC battery low

    Hi all

    I ask your help.

    I have 15-inch Toshiba Satellite C50-B-19V laptop.
    It is 2 years old.

    I get RTC battery low message the laptop turned OFF for awhile (without adapter).
    When I turn it on, I have to re - set the Date and time in the BIOS.

    So I fully recharge via an adapter, and every time I put it to sleep the clock stops just when I put on standby.
    So if I put for example standby at 10:00 on March 2, 2016, and I turn it on at 12:00 on March 2, 2016, the clock says 10:00 and March 2, 2016 (the date is not lost).

    Laptop works well when on battery (without adapter).
    I have WIN 8 is installed.

    RTC battery low message is displayed after the laptop is off (no adapter) for a while... (a few days).

    Above mentioned laptop is NOT a pile of separate clock when back cover is removed (no battery is visible on the motherboard)...

    What to do in this case?

    Waiting for your response.
    Thank you very much!
    Ivan

    I would say that the RTC is low and that maybe it's the other side of the motherboard. Find and download the manual for your machine. All PCs have batteries for the CCF and to keep some of the BIOS settings. If it is not under an agreement of service of any kind, take it to a technician, you trust and let check. Otherwise repair by the company with which you have permission. The battery will be there somewhere. They can be painted, I saw that with some motherboards desktop.

  • Satellite C580 - plugged says a "Full load", unplugged it indicates "battery low 4%."

    My laptop is plugged (Satellite C580-1 kN) it says "completely charged 100%", but when unplugged, it indicates "battery low 4%."

    Does anyone know what is the problem?
    Thank you!

    How old is your battery?

    It is possible that the battery is not working properly...
    You must know that sooner or later any battery will lose their effectiveness.

    So even if the battery charge notification says battery is fully charged, the charge level may be very low...
    In this case only the replacement of the battery could help you.

  • Internal battery low - error 601 before Windows starts

    I have a HP Pavilion dv6 (XG737UA #ABA product number and model dv6 - 3163 cl) under Windows 7 Home Premium.  I tested, tried callibrating and nothing helped.  My battery meter shows that it gets only a max of 77% support and then stops to load.

    Then I turned off my laptop, unplugged the power cord from the laptop, then took the removable battery Pack, connected plug it back in and then laptop powered on with only the power cord is plugged in.  I don't have the 601 error message while booting.  Issues related to the:

    (1) this means that small piece of internal clock battery is not the problem, but rather the removable battery black, great is the question?

    (2) If Yes to the above, just replace the battery 593554-001?  I want a 6, 9 or 12 cells (I guess that the largest cell, the years more it will last)?  I found these: http://www.battdepot.com/us/search/opn/hp/593554-001.aspx

    (3) while I wait for the battery to arrive, is - it safe power the computer with the battery pack intact and functioning, or I want to only run the laptop with the battery and connected computer?  The latter will be difficult because I need to walk from one place to another with the laptop.

    Thank you!

    Hello mikechicago,.

    I see that you have an error message internal battery low. I'll try to help you.

    To answer, you have any questions.

    (1) is based on the fact that if the removal of the battery at the back, the error is gone, this would imply that the question is indeed with this paste and not the battery cmos.

    (2) on page 53 of the maintenance and Service guide, you will find the support of the spare laptop battery you with reference numbers. Who should answer this question.

    (3) it has not recommended to continue to use the battery. For now until you receive the replacement, it would be better to use it plugged in.

    I hope that it has been able to answer all your questions.
    Thanks for posting on the HP Forums.

  • On Satellite C55-A-19(r) battery low level

    I bought my laptop to 31/12/2013 and yesterday Toshiba Pc Health showed me that the State of the battery is low (red)

    I m using several hours a day and I find it very weird...

    Can someone help me with this?

    Hello

    How long the laptop runs on battery power?
    How long the battery does not load?

    The point is that your laptop is new and battery needs to be calibrated before it would have reached the performance.
    To calibrate the battery you must load and unload completely. This procedure should be repeated two, three times in the line.

    If this does not help, contact the ASP from Toshiba for the new battery.

  • RTC battery low - where is battery CMOS? C50 - B - 14 D

    I also get a message at startup and strangely in Windows, low battery RTC. The laptop will simply shut down.

    I suppose there is a fault or battery CMOS is actually dead. I removed the bottom to expose the jury and watched various tear downs, but still cannot locate the battery. I removed the main Board and the CMOS battery isn't here. Is there one on these units?

    It is a fairly new laptop and otherwise in good condition.

    Any help appreciated.

    Some models do not have an RTC battery, they rely on the main battery to keep the time.

  • Satellite L30 - 14F - battery low CMOS and delivers after BIOS update

    For 1.5 years, I have a Toshiba Satellite L40 - 14F PSL4CE.
    I encounter the error of CMOS LOW battery but I was unable to find to replace. Where he is?

    Second problem: after a BIOS update (version of the site) with the same setting in Windows XP, after I left the lid downwards and then save the workbook hesitates for about 2 seconds and the music stops. These problems were not present before the BIOS update.

    Thank you for the cooperation.

    Hello

    The BIOS battery can be replaced by only authorized service. to do this the laptop everything must be dismantled. By the way: see s operating manuals. You will find info how to load the BIOS battery.
    If I remember correctly the laptop must be connected to the adapter sector more than 48 hours. Check in the manuals.

    Maybe is my bad English, but I do not understand second problem.
    Can you please try to explain it again? I'm sorry.

  • Satellite A500 - battery low noise-how can I turn this annoying its judgment?

    Hello world

    I recently had the fantastic A500-1GL which was great... all out of this really irritating noise that occurs when the battery is less than 10%.
    I have already disabled the warning sounds in:

    Hardware and Sound - System change sounds - sounds - warning low battery alarm and critical battery level.

    Two of these sounds are different from that which is me crazy Drivin'. Its a very basic system beep and plays every 10 seconds or more. I NEED to know how to disable this feature because it drives me crazy! I can lower the sound, but having ovious disavatages!

    Can someone help me please?

    Thank you
    Mike

    Please enter the advanced power settings and check battery options here.
    Change settings for low and critical battery level (lower level fixed) and also check the battery notification low option. Here you can disable.

  • Satellite A45 - S121 RTC battery low or unstable CMOS

    I have a Toshiba A45-S121 that I got from a friend who has left the country...
    I keep going back to the same message over and over again and cannot activate it because it keeps doing again and again.

    The message is: "RTC battery is low or CMOS checksum is inconsistent, press F1 to reset the date and time." It would have been great if it was, that I should have done, but at this stage no button does nothing, and the only thing I can do is to restart... I looked on the net, and someone said to recharge, the main battery for 8 hrs, will do... NOT.

    Another said to rest with charger for 15 h and have the laptop on at the same time... NO help there.
    Another was told to change the battery Cmos... Did this... NO help.

    I tried F12 thing... the computer is located in the startup Toshiba logo, and as soon as I press another key, it goes back to this message... I can't do the BIOS, and I can't run it from a CD, until I have this message.

    HELP PLEASE.

    Hanks a lot.

    > The message is: "RTC battery is low or CMOS checksum is inconsistent, press F1 to reset the date and time." It would have been great if it was, that I should have done, but at this stage no button does nothing, and the only thing I can do is to restart

    Usually this or similar message appears if the battery CMOS/RTC would be empty.
    In this case, you should be able to solve this problem of the RTC battery.
    How to recharge?
    The laptop must be turned on and connected to the power supply for approximately 24 hours.

    But I see you've also already replaced the RTC battery and this message still appears.
    In addition it seems that you are not able to access the BIOS to change the date/time settings.
    Well, this would mean that there is a serious problem on the motherboard

    I think that only a laptop computer technician would be able to help you.

  • Satellite C855-18J-battery low after only 9 months

    Hi all

    I bought my C855-18J Satellite in October, there is, so just 9 months, and since last night, I get the message to consider changing my battery! I've never seen a battery that doesn't last even a year... How is that possible? and if I want a new one it's more expensive than 100dollars (excluding P & P)...

    They are now on low batteries?

    It is my first Toshiba computer (used from other brands before).

    > I've never seen a battery that doesn't last even a year... How is that possible?
    Possible is everything

    > and if I want a new one, it is more expensive than 100dollars (excluding P & P)...
    As far as I know the laptop is covered by the standard warranty that is valid 12 months.
    Then why you n t contact your dealer or a service of Toshiba and ask the new part/difficulty under conditions of warranty?

    In my eyes without any doubt the best solution here

  • Alarm of battery low battery/criticism on Equium A100-027

    I bought an Equium A100-027 running on Vista Home Premium this Feb. Since then, I installed some software, for example a software phone Nokia, bluetooth, Virus-A drivers & all updates from Ms.

    When the battery is low or critical, I get no sound alert, despite this option checked in the Advanced Power Options settings and using the template to default sounds Win.

    The card sound & speakers work certainly I get sound notifications of Win and can play CDs, etc.

    Is there a driver/software that can be reinstalled to get this working again as system restore would only let me go back a month.

    Thanks for any help,
    Markus

    Hello

    I saw your post before, and I understand that you need help.
    I can give you the following suggestion:

    -Updated to the latest version of the bios. (Check this site out: http://eu.computers.toshiba-europe.com/cgi-bin/ToshibaCSG/download_bios.jsp?service=EU&mode=allMachines)

    -Pick up your machine and update all THE drivers/tools/etc, but before installing some 'foreign' software, check if the "beep" is working properly (for things like go here):
    http://EU.computers.Toshiba-Europe.com/cgi-bin/ToshibaCSG/download_drivers_bios.jsp)

    -Install other software (Nokia Manager, etc.) and check after each newly installed software, if it still works. If after you install specific software, the "beep" doesn´t work anymore, then you know where the installation problem and you have some good software troubleshooting. ;)

    If you have questions: just after :)

  • iPhone 3GS force "battery low" startup

    Ok.

    If last year, I got this 3 g iPhone I tried to go to work. He had a kind of logical card error or something. After hours spent trying during a week or two, I gave up. Since then, I have collected 8 others. But today, I decided to give it another shot. It 'won't' always reload. Already, I have determined that there is a hardware problem. I hit it hard enough and it will say that it charges for a minute and then stops. Even when he says not that he is in charge, it does not start. However, I know that there a load because when I unplug it, it shows the low battery symbol plug. When it does not start, it will load up and work for a few days or stops automatically because of the "stack". So, is there a way to force the phone to start and bypass auto power off low battery? any help is appreciated! Thank you!

    No - honestly it sounds like this iPhone battery is just worn out.  Until or unless you put a new battery in there, I doubt this will never be usable again.
