Satellite R850 - faulty battery indicator? How to calibrate?

My Satellite R850 stops at about 70% of the battery capacity. It is not suspended, just power off. Market is possible only when the AC adapter is reconnected. My first guess is that (after only a year of daily use), the battery had its best time and must be replaced.

But why the battery indicator only shows the right capacity, so I can get a warning to low battery power?
Is there a tool or method for recalibrating the battery?

Hello

To me, that shows that your battery is defective.
Usually sooner or later each battery needs to be replaced because the battery life is limited.
I have no idea how old your battery is but in my case the battery is 5 years old and he hold the power for about 2 min only. But the funny thing is that the battery indicator indicates battery is fully charged (100%).

However, you can extend the lifetime of battery a little bit. You need to calibrate the battery from time to time in charge and discharge of battery. This procedure should be repeated several times is the row
But I guess these calibrations and your battery failure doesn't help much.

    Hey Buddy,

    I'm not quite sure, but AFAIK this low battery beep could be also caused by the BIOS

    If I remember well in the BIOS there is an option called beep, beep PC or similar and you should disable this option. That means the computer won't no beep sounds.

    You can confirm s work?

    Then plug in the power adapter and charge the battery until the battery indicator (LED) would turn to green.
    This must be done and repeated 2 - 3 times in the line.

  • Re: Satellite A100-811 main battery indicator is OFF

    Hello

    I have a toshiba satellite a100-811 and the problem is the following:
    When it is plugged in, the main indicator should be blue (full load) or orange (charge).
    Now it is off (no light at all).

    I unplugged DC and back is plugged and the fire was orange for a few seconds and then went off again. Battery is charged at 99%.

    What is a battery or a motherboard problem?
    The laptop is old. Should I be backing up my files?

    > Should I be backing up my files?

    You should always have a backup of your files in case something bad happens to your laptop or HARD drive.
    But the battery issue would not affect your files directly.

    However, try this:
    Remove the battery and unplug the AC adapter.
    Now hold down the power button / stop along 30 sec.
    Then, plug the battery and plug in the AC adapter and check if the battery indicator would be IT.

    But I think that if the laptop is still running even if the AC adapter is not connected, then the battery should be ok

  • Satellite C650: Battery indicator is always orange even after a full charge

    My toshiba laptop C650 has indicator sistem to always load amber.
    Even if it is fully charged.

    If I disconnect from charger it works on battery long enough, that tell me may battery is ok.
    But why this indicator stay amber? Is there a problem?

    I have to worry about this?
    Thank you.

    Hello

    Usually, the battery indicator should go green (color depending on phone model) if the battery is fully charged.
    If the battery indicator changes not amber green/blue then this would mean that the battery is not completely charged
    Well, maybe you should try to calibrate the battery once more
    Discharge the battery to his completely empty, then load it again until the battery status would show 100% charge then discharge the battery once again this procedure should be repeated two, three times in the line!

    If this is not enough, well, you might try a new battery but I put t know if its worth it to buy a new battery if the current battery still works well.

    Dear support,
    I have a problem with my battery and have searched online help.
    (it says "recommended to change the battery")

    My problem is that I can't ask since TOSHIBA says that there is no such thing as my type of pc support online!
    Seems strange to me.

    Toshiba Satellite L500-1W5, that is what is written below my pc.
    Also there is no serial number... 3A467845K

    Could you please show me how to do?

    I will follow the recommendation and use it without battery?

    Hello

    Sometimes it of possible to increase the performance of the battery if you calibrate the battery.
    The battery must offload until it is completely empty.
    Then recharge the battery until the battery indicator (led) turn to the green or blue (this depends on model laptop). This procedure should be repeated several times in the line
    But if it does not help, I guess that the battery must be replaced.

  • Satellite R850 uses only 25% of the CPU

    Hey, my toshiba satellite R850 uses 25% of the CPU, I got 8 GB of ram, and most of the higher quality games have 20-30 FPS, is there a possibility to make it higher?

    Thanks for the help!

    How do you get this value or how do you know that only 25% of the CPU performance can be used?

    Have you noticed this behavior of the laptop is running on battery or power?

    Usually, you can change the max and min of CPU performance values in Windows power management. This allows you to decrease the CPU heat dissipation and to increase the working time of battery.

    In contrast to Intel CPU support between that the enhanced SpeedStep Technology puts both voltage and frequency in tandem up and down level to processor support.
    Simply said: the CPU runs with only if more high performance s necessary!

    I think the game frame per second question is more related to the graphics card than the CPU.
    Not quite sure this graphic card your laptop stand, but in case you want to have big game performance, the laptop should be equipped with a GPU external nVidia or ATI.

  • Satellite L755-11J battery low charge question

    I have a laptop Toshiba Satellite L755-11J for nearly three years.

    It is now stated the battery down and to replace.

    What is the average time that the battery lasts? Understand that they take some time, but seems a little earlier.

    Looking for a replacement online through Toshiba but can't seem to see it.

    Thank you.

    > What is the average time that the battery lasts?
    To my knowledge, the common battery would have started loos performance around after 500 cycles of carbonization.

    However, to keep the battery performance the longer possible, you need to calibrate the battery from time to time. The battery should be completely discharged and then recharged until the battery indicator should appear green (or blue).
    This process must be repeated 2.3 times in the line.

  • Re: Satellite M60-188 - battery won't charge

    Hello

    I recently received a Satellite M60 and this morning when I plugged back the charger the battery indicator in the taskbar has shown a full battery when there was in fact only 4% left. And sudenly my computer stopped after a few minutes bipping because the battery is low.

    It's my second Satellite (the other was aM70 and I changed the battery and the charger of the M70, but the problem remains the same) and now with my M60, it seems to be exactly the same problem (I only got the M60 for two weeks), I don't understand how the battery may already be damaged after 2 weeks.

    If anyone can help me, thanks

    Hello

    I guess that your new laptop Satellite M60 was not new and it s a laptop second hand. Then the battery and the adapter AC Lentivirales, second hand, coins, or you use the Satellite M70?

    However, I think that your battery is simply defective and must be replaced. If your laptop works with the AC adapter plugged there should not be a problem with the motherboard I think but a laptop technician can check this

  • Satellite C850-A823 - battery quickly

    Hello everyone,

    I just bought a * Satellite C850-A823 * with a lithium-ion battery, Win7 Home Basic 64-bit battery. The problem is that the battery is from 30% to 5% in no time. And in no time, I want to say that I check the battery and it's 30%, a minute later I check and that's 5%!

    The rate of the consumed battery is normal when it is greater than 30%. But when he reached 30% it goes nuts and fled to 5% in one minute!

    What will I do guys?

    Hello

    Calibrate you the battery while using the notebook for the first time?
    The battery needs to be calibrated at the beginning.

    Charge the battery until the battery indicator would turn to green. Now, disconnect the power adapter and run the laptop on battery until the battery runs out. This should be repeated several times in the line.
