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

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

    Graham

    AFAIK, you can't order directly in battery Toshiba but each service provider authorized in the United Kingdom can get the original for you battery.
    I recommend checking the Toshiba support page under http://eu.computers.toshiba-europe.com > support & downloads > find an ASP.

    Any tips?

    Sonaya

    Hi Sonaya

    I can understand you but cheaper battery unfortunately isn't the best solution. What you need is compatible and original battery for your laptop.

    If possible, wait a bit, save the money and buy the right one.
    When you remove the original battery, you will find the exact reference. To order a new one.

    Anyway, I think battery cheaper than you can find on ebay. Check it out and compare prices.

    Carol

    I put t know where is the cheapest place to purchase the battery, but in my opinion, the offers online are the cheapest.
    You can see the Toshiba site options and accessories:
    HTTP://EU.COMPUTERS.TOSHIBA-EUROPE.COM/CGI-BIN/TOSHIBACSG/JSP/OPTIONSANDACCESSORIESHOME.DO?SERVICE=EU&ID=ONLINE _ SHOP

    Here, you can select your model of laptop, and you will find the compatible battery.
    You didn t write about you model exactly but I think that the battery pack (Li-ion, 12 cells, 6450mAh) with the PA3382U-1BRS part number must be compatible. But check before you buy!

    In any case, you could Google for that number and I m you will find many offers online.

  • Question about volume adjust the volume knob - Satellite Pro U300

    Hello

    I have a problem with the volume control. When I adjust the volume using the button on the left side of the laptop, I can only choose 3 levels of "loudness":

    No volume, very quiet volume and maximum volume (from rabies).

    Is this normal, is not anyone have problems with this?
    I hope that the problem is because of the digital volume adjustment screw. The adjuster does not record the exact position of the volume button. Every time when I get a phone call at work (I listen to internet radio), I turn off the radio by using the adjustment screw on the side of the laptop. When I end the phone call, I always need to open the laptop and the volume on the windows task bar, because when I use the device volume control on the left side of the laptop, it will just immediately at maximum volume.

    Welcome them

    Hello

    It s very strange that your volume control contains only 3 levels of volume
    I noticed that Toshiba has released a new driver (v. 6.0.1.5473) sound on the European driver page.

    How about if the update driver sound?
    Audio driver certainly controls the volume sound and in my opinion it s worth a try.

    Good luck

  • Re: Satellite U300 hibernates when the battery is very low

    Hello

    I bought my satellite U300 141 two weeks ago.
    The computer is not put into hibernation when the battery is very low.

    I checked the settings of vista, default 2% of the battery capacity, the laptop must Hibernate. But mine is not.
    But I noticed that the battery level does not fall below 5%. I tried to change the setting of vista from 2% to 5%, but it has no effect.

    Telephone toshiba support told me to update the package of the value 'stretched out' or something like that, but it has no impact too.
    the problem is still there.

    Anyone have an answer?
    I also tried to update the BIOS, but during the upgrade process, the software told me that I can't because I'm not the administrator of the computer, I am sure I am.

    so, if someone can help me please...

    Please check first if hibernation was enabled in Vista power options.
    Then you can assign to hibernation level up to 10%

    Maybe then your laptop will be able to enter hibernation mode

  • Re: Satellite Pro L670 - can I turn off the sound when the battery is empty?

    Hello

    Is it possible to disable the bios beep when the battery is empty or the laptop's Hibernate?

    I have a Toshiba Satellite Pro L670.

    Even when the sound in Windows is turned off the laptop do a annoying sound.

    Thank you!

    Maybe it sounds silly, but I put t understand why that should be disabled. When the battery reaches the critical battery level you will be informed about this and portable must be connected to the power running or you have to save your work and turn it off.

    Do you really want to work until the battery is completely discharged?

    Anyway, AFAIK this notification level BIOS cannot be disabled.
    Let's see if someone else is better informed than me.

  • L50 - B satellite will not start when the battery is completely discharged

    Hello

    My Toshiba L50 - B won't start when the battery is fully drained but connected to the power outlet.
    I try to work most of the time on the battery to keep the battery in good shape, but when I forgot to turn off the battery drains and the system will not start when I plug in the adapter.

    The battery charge indicator is orange light as it should. Only when the battery is fully charged to 100%, it will run at startup and function normally after that. I tried to turn on the laptop several times during the charge cycle, but only when the charge indicator changes from yellow to white it starts. Tested for 2 bodies.

    My old Toshiba always immediately turned on when I plugged the adapter even when the battery has been completely drained. Am I missing a setting somewhere?

    Thanks for responding... I hope well :-)

    Toshiba L50 - B
    Windows 8.1
    Any standard/original setting since I only acquired this laptop a month ago.

    The laptop should light up if the power adapter is plugged in and power the laptop corectly any if the battery is empty or during charge.

    Please check the version of the BIOS that is available on your mobile phone and compare with the BIOS available on the page of the Toshiba UE driver
    Maybe you need to update the BIOS, but to be honest, the history seems really odd to me and I m afraid that there could be some power supply electronic problem

    So in the worst case, the laptop must be checked by authorized service provider.

  • Satellite U300 turns off when the battery has been removed

    Hello

    I'm on the laptop with the battery in place, and the power supply plugged in.
    That's when I take off the battery (always plugged power) who, after 5 seconds the laptop powers off.

    It's not happened before and now it happens ALL the time every time I have to remove the battery.
    I noticed that when the battery is removed, the battery light is always on – if for some reason any cell phone still thinks the battery is connected.

    For me, it looks like an electronic power supply problem.

  • Use of AC when the battery is at 100%? (S7-391)

    Hello world!

    I have been affected by the worst support from Acer, I have no problem with the ultrabook himself (Acer Aspire S7-391) but I have some doubts about pilots and other things, that they have avoided answering many ways. So, here's the thing:

    This ultrabook has all drivers that could be use the AC power when the battery charge reaches 100% to avoid tampering with the battery?

    The thing is that while I have 100% of the battery and the ultrabook is connected to the power adapter, it always seems to be draining the battery power and recharging it back to being 100% all the time.

    When I ask about the drivers, who might or might not be installed, I just need to find a way to access this functionality if possible, and if I can't, I need to know as soon as POSSIBLE so that I can start unplug the laptop right after that the battery has reached 100%.

    Thanks in advance.

    As you said with Connector 2 power pins can also disconnect the battery charge. It can disconnect the power supply from the battery charging circuit when the battery reaches a particular % with the laptop running load in power cables. I do not think that your computers support portable setting the level of charge of battery to a % custom. Your laptop must have a particular hardware and BIOS that supports. In some laptops, the BIOS has the ability to define a particular % of battery charge. I read somewhere that windows 8 do not support this feature, old version of windows (Vista) support this feature.

    Some write up I found online to help you.

    Memory effect

    First of all, it is necessary to unfold a myth that persists in the minds of many people.

    The effect of stack memory.

    In the basis of lithium batteries, it is in fact a myth, it applies only to the old nickel-based batteries. Therefore fully discharge and recharge the battery are completely useless and even harmful as discussed below.

    The modern lithium battery can be charged independently of its current percentage, because he has absolutely no negative effect in his performances.

    Should I remove the battery when the a/c is connected?

    Many users of portable computers have this question and we will answer it right now:

    The answer is: YES and NO, it depends on the situation.

    Have a fully charged battery and the laptop is connected is not harmful, because as soon as the load level of 100% of the battery stops receiving the energy load and this energy is shorted directly on the power of the laptop system.

    However, there is a downside to keep the battery in the holder when the laptop is plugged in, but only if he currently suffers from excessive warming caused by the hardware of the laptop.

    So:

    -In normal use, if the laptop does not get too hot (CPU and hard drive around 40 ° c to 50 ° c) the battery must remain into the Jack of the laptop;

    -Intensive use, which leads to a large amount of heat produced (i.e. games, temperatures over 60 ° c) the battery should be removed the socket in order to avoid unwanted heating.

    The heat between the fact that he has 100% load, is the great enemy of the lithium battery and not the plug, as many might think so.

    Battery discharging

    Full battery discharges (until the computer laptop power shutdown, 0%) should be avoided, because he insists a lot on the battery and may even damage it. It is recommended to perform partial discharge to levels of capacity of 20 ~ 30% and frequent accusations, instead of performing a complete discharge followed for a full charge.

    Laptop PC battery contain a gauge of capacity that allows us to know the exact amount of stored energy. However, due to the charge/discharge cycles, this sensor tends to be inaccurate overtime.

    Some laptops include in their BIOS, tools to recalibrate the battery meter, which is nothing else than a full discharge followed by a charge complete.

    So to calibrate the gauge, it is desirable, in all cycles 30 discharge, a full uninterrupted discharge, followed by a too, non-stop, full charge.

    An inaccurate gauge may have to the fact that the capacity of the battery are values are false. The battery can report that he still has 10% of capacity, when in fact it has a much lower value, and this causes the computer to the unexpected shutdown.

    Cycles of discharge (or charge) are to use this charge battery (100%), but not necessarily all at once.

    For example, you can use the laptop for a few minutes in a day, using half of its e ability then it load completely. If you did the same thing the next day, it can be considered a discharge cycle, not two, so it may take several days before finishing a complete discharge cycle.
