Portege M900: Battery and load problems

I hope someone here could have helped me out in my problem. I bought my last Toshiba Portege M900 2010. I always want to plugin the charger my laptop when I am at work.

It presents a time that when I turned on my laptop, the battery was about to be empty as the remaining 7%. I took my charger and plugged. After 5 seconds it turns off without any warning or so.

I checked the lights in the laptop, the "light of load" is not on although charger is plugged into the outlet. I tried to use my Toshiba Satellite laptop charger and it worked.

I tried to disconnect the battery from the laptop Toshiba Portege M900 its place and plug the charger again but there still does not turn on.

So I took my Toshiba Portege M900 to nearest service center. But surprise when I arrived and on the problem of the technician, the laptop turned on after it was plugged. The technician said, he saw no problem because the laptop was in charge and it works right.

But when I took it home, whenever I have remove the magazine from the taking of the laptop, it turns off immediately without any warning eventhough that battery is charged to 100%.

And there were times, even if I remove the battery from the laptop but always plug the charger... the laptop will always be NOT PUT on.

I tried to check the Toshiba PC Health Monitor, but it seemed that the battery works well. What do you think seems to be the problem? Is it the charger, the battery, or the power supply or the motherboard?

> Is the charger, the battery, or the power supply or the motherboard

I put t think its battery problem.
Why? Because the laptop does not power upward even if the battery is removed but connected to the power adapter.

Jack _Power? _
Perhaps. It might be possible to equip jack or connection between the power supply and the card mother isn t ok.

_Motherboard? _
It could be a problem with electronic control gear that is part of the motherboard but once more; It's just an idea

_Charger/AC adapter? _
Hmm, you said that the adapter has been tested with another laptop and it worked. So maybe it s question no AC adapter.
But are you sure that other phones have not run to the battery power?
The adapter has been tested correctly? It is an open question.

Another idea:
What version of BIOS you have installed the M900?
Find an update of the BIOS for the M900 protégé
+ Updated BIOS version 2.40 for Portege M900 and Satellite Pro U500 (for PSU56 *, PSU5C *, PSU5J *, PSU5Q *, PSU86 *, PSU8G * and PSU53 * ONLY) +.
http://PC.Toshiba-Asia.com/support/drivers/details/30516

You will find a detail on the correction of a problem:
+ System can not turn on without using the AC adapter / CC after the battery has been detached and attached again. This problem has been fixed. +

Please check if your Portege M900 is one of the mentioned models and check if a BIOS update is available for your device.

  • Satellite U 300 - battery and sound problems

    Hi, I was wondering if anyone has had similar problems as me:
    My laptop is only two years, but last year his work only intermittently. I get messages saying that the driver is not installed, until one day he will decide that the driver is installed after all and works very well. Until the next time it stops working. There seems no rhyme or reason for it. I gave up trying to reinstall the driver, because I know that (possibly) the sound will come back without intervention from myself.

    My second problem may be connected - I have problems every now and then close the laptop. I try to put in mode 'sleep', but is not complete the process, and the blue light comes on. When I then open the cover, very often, the screen stays black and I have to turn off the machine and turn it on again the force again.

    Then recently, I noticed a sharp drop in the battery life (less than an hour). He also annoyingly started losing all power and cut until the indicator showed all the usual warnings of low power.

    Anyone know if these problems can be linked, and whether they can be fixed? A new battery will fix it? To be honest, he arrived at a point where I think to buy another laptop do since they are really starting to get frustrating!

    Thank you very much

    Gooday,

    I also own a U300 I bought about 2 years ago now, I had no problem with the sound but didn't have any other problems with my 1-2 months battery life after life - 20-30 min. I just baught a new battery and it is promising, I just did the first load and it lasted long, however the windows said it had 0% remaining, but I pulled out another 30-45 minutes the dough until it went flat. If you look in your event log do you get the message

    ": The embedded controller (EC) has failed in the specified time-out." This may indicate that there is an error in the EC hardware or firmware or BIOS is accessing the EC incorrectly. You should check with the manufacturer of your computer for an updated BIOS. In some cases, this error may cause the computer to function properly. »

    It is listed under ACPI in the event log.

    see you soon

  • Laptop HP ST09 long duration of life: battery secondary load problem

    I recently bought a HP laptop computer ST09 long battery life, but it does not load how as I expect and cause me pain.   My computer is a Zbook of 15.

    Both batteries are detected by my Windows 7 number of functioning, however when an AC adapter is connected only the original battery charges.  This way in order to charge the secondary battery, I need to physically disconnect the original battery and have only the ST09 in.

    It is a very annoying procedure have to do whenever the secondary battery is discharged.  Is anyway at the same time load at the same time or just charge the secondary battery when the two are connected?

    OK done something that essentially solved the problem. There is a 'Quick Battery Charge' feature that can be enabled in the BIOS which stop the primary battery to 90% charge and launched a secondary battery loading to optimize the charge cycle.

  • Satellite Pro A100 and load problems

    Hello everyone. New Member here.

    Got a huge problem with my laptop. I have a satellite pro A100-830. Part number: PSAACE-00W002EN. About 2 years ago

    I can run on the current system. But it will not work on battery. I just bought a new battery and it shows on the computer.
    I get indications are:

    battery charge amber lit.
    Light on power
    Power meter indicates the battery charge. I connected new battery and it shows 47% and now 3 hours later its still 47%
    If I unplug the power to the computer shuts down and will not work on battery.

    the AC light seems to be slightly duller than the one next to him, if that makes sense.

    Ive tried updating the BIOS etc but I'm ideas if im honest as im not a computer pro. I searched the internet but I can't find an answer

    Huge thanks in advance

    Stand by.
    We need more explanation here.

    You have the same problem with the battery and you have bought one new in the hope that everything will be OK?
    Have you noticed the same problem with the battery?
    You bought original Toshiba battery?

    In my view BIOS update won't help you much. I think electronic power is responsible for this BIOS update ahs no influence on this.

  • Charging battery and power problem problem.

    The problem occurs only once I have start the load the laptop after that I used the battery for either a small or for a long period of time.

    The battery will begin to charge and the laptop runs from the power supply for 5 minutes at a time. After that 5 minutes, the laptop switches the power source primary battery mode, even if the laptop is plugged.

    Another 5 minutes after that, the primary energy source to switch back and the battery will begin charging again. It will constantly continue to do that, even when the laptop is turned off.

    This is asif that is defective, however, is the second adapter I used and the same thing happens again. I tried looking in the power settings as much as possible and can't seem to find anything that can cause this problem.

    Just today, I noticed that the battery light flashes sometimes white when the laptop has its power as the main primary energy source. I don't know if this has anything to do with this problem. I looked through the manual and support documents as possible and impossible to find a solution to this problem.

    If the battery is low, when I start the laptop loading, that means I have to stop using my laptop, that this process will continue to arrive and finally the battery will stop and the laptop will be extended even if the plug is connected.

    Help, please!

    Hello

    A friend of mine had a similar problem but on non-Toshiba laptop. The reasons because it is a dysfunction of the taken power there was a loose contact between the socket and the motherboard

    The technician said that the motherboard needs to be replaced because it would be too difficult to solder this Jack once again

    If the mobo was replaced, but it was a costly affair

    Don't know if this could be the case even, but this looks a bit like the issue of power supply...

  • Satellite Pro A30 - life battery and load

    First my laptop warranty has passed some time, so I can't send it back unless I can and do pay
    but recenetly my laptop battery life is a bit dead lately, it may last an hour or so on it

    But I recently discovered that it will charge to 86% then start discharge even still with the AC adapter is plugged
    Any ideas? I think to the replacement of the battery, but I was wondering if this is what is causing the problem

    See you soon

    If the battery is 3 years +, then there might just need replace.

    However it could be caused by other things, supply or circuit of the DC IN jack on the motherboard may have a problem.
    I would like to send the laptop to an ASP for a quote.

  • 0% Apple pencil battery and does not load

    I use pro iPad Apple pencil to draw every day, and I noticed that my Apple pencil stopped working today.

    I plugged in the charger with the pencil and iPad widget, it shows that there is 0% battery left and the lightening bolt charge appears. Cool for 30 minutes, that the battery is always 0%. Unplug the charger pencil crayon disappears immediately of the widget. The same thing happens if I plug the pencil in the port of the iPad.

    I tried hard restart my iPad, rematching in pencil, but still a pencil appears in widgets display 0% battery and load relief icon and by unplugging the charger pencil / iPad disconnects the pencil of the iPad immediately, regardless of the duration of the load.

    Anyone had the same experience before?

    Make sure that the lightning connector is fully engaged in the iPad or the charger. When connected to the iPad, the cover of lightning in the pencil should snap.

  • BlackBerry Smartphones "BOLD" battery draining - overheating problems

    Hi all

    I'm new here I have BlackBerry for almost 2 years (curve 3000) and I was really happy with it (no problems) then I bought "BOLD" Saturday and has exhausted the battery - overheating problems! I downloaded the new software from T-Mobile Croatia site (they have one last but which did not help) after recharging and stay all night, he went flat within 6-7 hours so I went today (Monday) and they swapped the device for me, now I'm waiting to see what will happen. I have 4 questions:

    1 can I download new software version of the device from the BlackBerry site that even I bought in Croatia from T-Mobile and which will have consequences on the device? If yes what are they?

    2. what causes this battery drain - overheating problems and how they can be stopped?

    3. is Facebook app in conflict with "BOLD"? Yes I have it on mine.

    4 are all the other apps in conflict with it, i.e. Windows Live Messenger because I have too much that one on it?

    Thanks in advance!

    1. no consequence... the latest version of the "BOLD" OS device is located here:

    http://www.BlackBerryForums.com/General-9000-series-discussion-bold/194263-OS-9000-bold-4-6-0-477-4-...

    2 could be a number of issues, several. You have 3G enabled on your "BOLD", on the one hand, (manage connections > Mobile Network Options?, and you have a 3 G with Tmobile Croatia network?) I know not flippant, you could ask that. If your device is constantly looking for a 3 G network and not finding what will cause the big battery drain.

    Check your applications running in the background. There are usually four or five applications that will be always running (Messages, Call Logs/phone, BlackBerry Messenger, home screen and the browser; there are others such as BeamBerry and alarms which will run also). Ensure that the browser is NOT on an active Web page (must return the bookmarks page only). Close all other applications that do not need to be running (the camera or a game you were playing or Google Maps).

    3 No.The FB app is developed by RIM.

    4. What do you mean 'in conflict '?

  • Portege R500 - battery problems

    Hello

    I have problems with my battery. The battery seems to load OK, but sometimes recently, when I wake the PC, the light flashes orange and nothing seems to work. If I remove the battery and put back again, it starts again OK and the battery says it is fully charged.

    Any ideas?

    Angus Walker

    Hi Angus Walker,

    Why do you think that the problem is related to the battery?

    Awaken the PC way, it is in mode 'sleep'?
    If so, I think that it another problem that might be a software based on s. I average if you remove the battery and put it again, and then the computer starts the battery is charged, your computer is able to boot with the battery only, so it seems to be ok.

    In your ad, I can t find information on your operating system you are using?

    I would also try to load the default settings in the BIOS and test again. Also, make sure that all Windows updates are installed if you are using Windows as your OS ;)

  • Camileo load problem (solved) and a general question!

    Hi all!

    First of all, I was going to ask for help as to why the Camileo S10 wasn't supported (the orange light was not blinking) and I had seen a few people with similar problems.
    The solution?

    Give the contacts of the battery clean.
    The sticker of insulation that comes on it must leave some kind of residue on it, and just avoid the charges. [Now it blinks far fortunately:]

    So my general question was, is it possible/desirable to use the camera on the network?
    Instead of constantly drain and recharge the battery during long shoots, I prefer to leave it plugged!

    Thank you very much in advance!

    Paul

    Hello

    I think that the handling of the battery is always the same, regardless of what product it is
    From time to time the battery must be recalibrated.

    This means that the battery should be completely discharged and then after you need to load it again until the battery could reach 100%

    I do this with all my batteries; laptop battery, laptop battery and battery of digi cam.

  • Equium L10: Problem with the main battery and battery RTC

    Hello

    I have the Toshiba Equium L10 and it is about 14 months old and I have problems with the battery and how much time it takes after a full charge. I also have problems with the RTC battery and an ERROR 0271: check date and time settings message when I turn on the laptop.

    Regarding the battery, I can fully charge it upward in about 3 hours, but when I start to use it, apparently in the last few hours around one and a half or so and then it needs to be recharged. I can have down for about 40 minutes and then turn it off and come back later or in a day or two. How long should I expect from a fully charged battery?

    About the batttery RTC, it really becomes a pain and I only started to get the message of the ERROR 0271 start-up, in recent weeks. I can charge the battery pack and then leave for a few days, but when I turn it on, I get the message ERROR 0271 on the date and time incorrect. Surely after a full charge, the RTC battery should last longer than a few days?

    The manual says that if the RTC battery is exhausted or becomes weak, you must charge the battery of the CCF for 24 hours, in a different part of this manual indicates between 24 and 48 hours, but how can load you for long when the sections concerning the charging battery pack status after charging the battery you unplug the power adapter because leaving connected will shorten the life expectancy of the Battery Pack. So, how we can charge the battery of the CCF for 24 to 48 hours if we shouldn't leave the AC adapter plugged in once the battery is charged - which is nearly three hours. Suggestions about these problems would be appreciated.

    Besides we all know that it is easy to change the CMOS/RTC battery in your desktop base unit, but is it easy to change in a Toshiba Equium L10?

    Concerning

    Brave0

    Hi Brave0,

    The normal recommendation for the CMOS (RTC) battery is to leave the laptop connected to the power supply at least 12 hours when the main battery is fully charged. The charging circuit is going to hijack the current to the load automatically RTC battery and no current will be forwarded to your main battery.

    Recommendation do not leave the power adapter is plugged in the main battery is fully charged is really only applicable to older laptops that used no batteries Li - ion and therefore they had to be completely discharged before recharging to avoid any effect 'memory' of the battery.

    With modern Li-ion batteries, it is quite safe to leave the battery when fully charged and still power the laptop from the AC adapter. The charging circuit will pass all the battery charge if it is fully charged.

    Kind regards

  • Lenovo IdeaPad Y560 does not load, battery and charger are OK

    My 3 year old Lenovo Y560 laptop i5 does not load when I turn on with the battery in it everything works normally, but when I plug in charger nothing happens. I checked the charger and it works great, its output is stable 20V. When I remove the battery and try to power the laptop with charger only, LED indicators light up for half a second and nothing happened. With closed laptop battery and charger plugged in, battery light flashes orange, about 3 seconds 10, without the battery even after several hours. I had no problem with jack for charging so far, so I think that is not due to a problem. I tried something with the power for 30 seconds button now and it did not work. Does anyone have the same problem or at least an idea of how to solve this problem?

    It seems that your charger is broken despite the supply voltage. My guess what it cannot deliver sufficient power. Try to find someone with the same charger (voltage, socket and polarity must be the same. There may be several amperes/watt) and try to use it. If you do not know someone who might have a charger as it try stores electronics or services.
