Satellite M100-152: RTC jumps back one hour every hour

Hello

I have a Satellite M100-152 for about 14 months now and I am very happy with it.
Since about 2-3 weeks, I have a problem with the clock (RTC).

If I set the clock at the moment (e.g. 09:23), he runs for an hour at 10:23 and then jumps to 09:23 then run again until 10:23, jumps at 09:23 and so on until I put the time again. The date does not change, of course, given that the clock does not receive at midnight.

There is no warning when starting, the battery is low or empty (the warning is enabled in the BIOS) and it must not be empty now, right?
I tried to disable the synchronization and automatic summer/winter-time, no effect.
The problem seems to be totally independent of the laptop turned on, turned off, plugged into the electric network or disconnected.

Do not take each piece of information for granted, but that's how I feel it right now.

I have no idea and I have found nothing so far on the web.
All advice and tips appreciated!
Thanks in advance
Torben

Hello Torben

Please check if the warranty is still valid. If so contact authorized partner in your country and let Exchange them CMOS battery. Please don't do anything yourself, especially if the warranty is still valid.

    Hello

    where did you downloaded the driver? On the toshiba Web site? Maybe you should try the driver from realtek home page because they are native and absolutely clear things from other manufacturers. I think you should try "www.realtek.com" and install the driver downloaded from there, once you have uninstalled the driver for your machine.

  • Satellite M100-152 does not start

    Title says it all.
    When I'm back from the IGC-pause the screen was empty but of cold cathode (backlight) have been turned on yet.
    Fact a reboot by turning the PHONE works but the screen remains dark with cold cathodes offshore.

    Hard drive starts spinning so the cd rom (with disc inserted i.e.) but nothing happens otherwise.
    The only thing is that cell phone ring 4 times.

    Cannot change the boot sequence / device
    Don't start with the restore cd.

    Any suggestions / ideas what could be wrong?

    > The only thing is that cell phone ring 4 times.
    Looks a bit like a hardware problem. Usually, if the laptop will beep then an error has been detected on the Board!

    Seems that the portable technician should take a look at this machine.

    But have you tried to remove the battery and the AC adapter from the laptop for a while?

  • Location of the slots of RAM on my Satellite M100-152

    Hi people!
    First of all, sorry for my English :).

    I want to upgrade my memory from 1 GB to 4 GB, the maximum capacity (2 modules with 2 GB each). I already have the new RAM, but I'm not really sure of its specifications:

    My motherboard supports 667 Mhz with CL 4 (or 5) modules? (Now I have 2 x 512MB 533 Mhz)

    But most important:

    WHERE can I FIND THE 2ND SLOT for MY MEMORY of EXCHANGE IT (1 is on the back of my laptop)?

    Already read it is located under the keyboard... but how to get to it then! ??

    Thank you...

    > I want to upgrade my memory from 1 GB to 4 GB, the maximum capacity (2 modules with 2 GB each). I already have the new RAM, but I'm not really sure of its specifications:

    Why do you want to upgrade the RAM to 4 GB if the 32 bit Windows OS will not recognize all of the 4 GB?
    The 32 bit OS recognizes only 3 GB. Check the Microsoft page for more information!

    > My motherboard does not support 667 Mhz with CL 4 (or 5) modules? (Now I have 2 x 512MB 533 Mhz)
    It is not serious if CL4 or 5. Important is that you use modules 200-PIN SODIMM PC2 - 4200, as shown here in this page:

    > WHERE can I FIND THE 2ND SLOT for MY MEMORY of EXCHANGE IT (1 is on the back of my laptop)?
    As you say it s under the keyboard and the keyboard must be removed to gain access to the memory module!

  • Discussion of 'Windows 7' on Satellite M100-222 - complete

    Good day everyone! This post on 'Windows 7' on 'Toshiba' 'Satellite' M100-222.

    Perhaps, this method (and as some drivers & utilities) will be to apply successfully for other models M100 "Satellites". Because some very similar models on the technical level. For example, 'Satellite' M100-221 & ect. I want to share & discuss. Because reliable information and a practical guide on this subject on the Internet is virtually absent... or little information is not completely. I am having some problems. With these questions, I want to share. Perhaps, we will find a correct solution together. Please, join... Then...

    First of all, the BIOS update! This is necessary for 'Windows 7' If your BIOS version 3.00 update - Toshiba Satellite M100 BIOS update v5.60;

    Before install "Windows 7"... I updated my BIOS (v3.00) to v5.60 - Toshiba Satellite M100 BIOS update v5.60
    I did it by 'Windows' XP Pro x 32... Executable file simply run it and follow the steps.

    Note:
    There is two years that I posted the question in the present case (forums.computers.toshiba - Europe.com) on my CCF. Clock in the BIOS (I forgot the BIOS version. Original BIOS, I bought my laptop & no has not updated the BIOS then) was frozen. Sometimes the time indicators worked, sometimes not. Very little time. But indicators stood also hours. Time passing in the system. In the frozen BIOS - 13:13:13, for example. Can I update the BIOS - v3.00, I hope my CCF works again. Nothing... Two years, I worked with frozen CCF. Every day I corrected time in the BIOS manually. Seconds are frozen... Sometimes the time work... But really the time in the BIOS has been frozen. I know this isn't the RTC battery problem. Physycally battery is normal. I knew that it is a BIOS problem. Because tests revealed it - physycally battery is normal. BIOS no error message. As the problem of the RTC... Some gave advice on the forum, and I'm not a beginner... Nothing... The BIOS time is frozen...

    Thinking about upgrading the BIOS to... 'Toshiba' added value package v1.2.40 (Win7 x 32)... When installing I get the error message - 0x8146045B
    Tried to install different versions of "Toshiba" extra package. Same error... Guessed the BIOS update! Among the drivers & utilities in site 'Toshiba' BIOS for 'Windows 7 ' offer for Satellite M100 (PSMA1E) v3.00. But BIOS v5.60 shown for 'Windows' "Vista". Same platform, same core with 'Windows 7' (theoretically)... Basic logical approach! I downloaded & updated BIOS - v5.60! Great! BIOS has been updated... Perhaps, "Toshiba" value added package will install properly. I hope. I wait a few seconds after the system shuts down. I turn on my laptop & press F2 - looked at BIOS... Incredible... First of all, I've seen - seconds in my clock BIOS runs again! Each of us felt a sense of joy! But after two years... The BIOS time worked again! So, it's amazing! But don't be naïve. Certainly, there is a scientific explanation. I mean the BIOS update can help solve similar problems. But everything has to be studied in detail. After BIOS update, I installed "Toshiba" value package v1.2.40 (Win7 x 32)

    Then I found & download drivers & utilities. I checked with compatibility in "Windows 7". For two 'Windows 7' - x 32 & x 64 platforms... I'll find some utilities - Touch "Toshiba" & launch, its virtual, DVD - RAM software "Toshiba", silent acoustics, also central control Catalyst "ATI"... Here's a question open for me. But no problem, it's easy willingness...

    Then I install "Windows 7" x 64 ultimate (I managed to install "Windows 7" x 32 & drivers, before utilities).

    Always install the following drivers:

    Intel Chipset device software v9.2.0.1021 (Win7 x 32 & x64);)

    ATI Mobility Radeon X 1400 driver (Win7 x 32) or for (x 64 Win7) - requirement (download it on - http://catalog.update.microsoft.com/v7/site/Home.aspx & extract to the folder using any archivators.) Then update the VGA Standard of this folder drivers);

    During system reboot do the install & updates!

    And please, I beg you, help for the next:

    Everything worked fine! But yesterday I had the installation of material of "Toshiba" and receive the runtime error message! I know that "Toshiba" HW should be compatibility with BIOS! Please tell, anyone know what version "Toshiba" HW compatibility with "Toshiba" 'Satellite' M100-222? Or 'Satellite' model M100?

    And... problems beetwen Toshiba value added utility support package & Toshiba Flash cards! Flash cards do not work... I uninstall both and reinstall again... Same situation... A few days ago worked well... But not now... I don't remember, maybe change the configurations in the settings of Flash cards... Do not remember... Help to solve these problems. It is very important!

    For example, I looked for laptop Satellite A500 - Toshiba value added package v1.2.26.64 (Win7 x 64) & complect Toshiba Flash cards support utility (Win x 64) v1.63.0.4C! Perhaps, Toshiba value added package v1.2.40 (Win7 x 64) incompatibility with Toshiba Flash cards support utility v1.63.0.4C (Win x 64)? Versions, I think that...

    Does anyone has any information about these utilities for platform "Windows 7":

    "Toshiba" Touch & launch;
    'Toshiba' virtual sound;
    DVD - RAM software;
    Acoustic silencer.

    and "ATI" Catalyst control center... For the full control "ATI" Mobility Radeon X 1400 graphics adapter "Windows 7". I can only update the graphics card drivers. But do not know which version is the compatibility with the graphics card "ATI" Mobility Radeon X 1400 "Windows 7".

    Thank you! I have very little time... Lots to do! I will try to fill the drivers on sharing files or torrent. But for this I need to collect all the drivers and utilities. I have to check. Week of rest, I set to work and share with you what I could.

    Thanks again!

    Hello Gabriel

    You wrote a very interesting announcement, but, as you can see, almost ten days later there is no one comment. From time to time I m here in this forum and I have noticed that people are not interested to read these stories.
    Problem is that you gave a lot of information and who should write the serious answer must create real concept how to proceed and has spent a lot of time for the full discussion.

    I put also t have time for an in-depth analysis, but what I can say is follow:
    If you want to install more recent OS on the old model of laptop as a first step, you should check if your model (your is PSMA1E) is supported for the operating system you want to install. I can see your model is not supported for 64-bit OS, just for 32 bit Win7.

    So what to do?
    You must have a list of all hardware components and try to install the drivers available for other models of laptops. Some 64 bit Vista drivers can be used on Win7. HwSetup designed for 64-bit Vista should work fine on your Win7 installation. I did several times in the past, and each time it worked fine.

    Toshiba touch & maybe I get m wrong but this old tools is known to me for WXP only. I've never seen in Vista or Win7.
    Virtual sound the same as for T & l. it was designed for Windows XP Home edition only.
    Two others can be also for WXP only.

    If you don t have such tools for Vista you'll them for Win7 too.

  • Lose Satellite M100 PSMA0A time but no date.

    Hello

    I have a portable Satellite M100 (PSMA0A-0J4002), who has problems with the hold time. He lost several hours in normal operation (mains or battery power or even with no battery and only AC). It stops when the computer goes into hibernation or is disabled.

    My Windows time zones are correct and I turned off automatic updates of internet time too.
    The strange thing is that the date never changes! It's not 1980 or similar when the battery is removed. That means it's not the CMOS battery?
    I disassembled the laptop looking for the CMOS battery, but it is soldered in. Is this correct?

    I don't know if it's relevant or related, but sometimes the screen turns black after emerging from hibernation and the laptop must be turned off and when he comes back he asked something like: clear memory and reboot or restart.
    I have to choose erase the memory and restart. Very rarely, I also have the blue screen of death with count upwards saying that memory dumping (I think).

    I deleted my firewall and AV programs but still lost time.

    Anyone is able to help please?
    Is it likely to be material, battery CMOS or software?

    Thanks in anticipation!
    Lewis

    > I disassembled the laptop looking for the CMOS battery, but it is soldered in. Is this correct?
    I m not very well how it s mounted on laptop M100, but in many cases the CMOS batteries are not easy to remove it s always a job for technicians of the ASP

    The issue of the date and time may be linked to the CMOS battery
    Usually, you can charge this battery easily.
    In order to load the CMOS battery, the laptop must be connected to the power adapter and the laptop must cover more than 20hours.
    After that the CMOS battery needs to be recharged.

    But if the question seems yet, then you should check if the update of the BIOS might help if not it s a motherboard problem that should be checked by a technician of laptop!

  • Satellite M100-JG2 HotKey and date and time problem

    Hi all

    I'm not very good with computers, and I've had some problems for a while now. My laptop is almost three years, I don't know why I'm writing this after so long but anyway. I think they are called "keys" or "launchkeys", hopeyfully, you know what I mean, but anyway they do no more work. They worked for a while, but they do not work now. I went into the control panel and went into the 'Toshiba' orders and tried to change what does each control, but it still does not work. No one knows how to fix?

    Also, another problem that I had since I first laptop is my date and time are screwed up. If I put my 15:30 time, it works perfectly, until around 16:15, that when he goes back to 15:30 and go all the way up to 16:15 and continues in this cycle until I manually change the time. I had a few friends (no professional) to look at, but can not understand. When I start my laptop I go to settings in the start screen, try to change it was from there, but it keeps going during the cycle. If I click on the time and click on the tab "internet time" and say "update now", it updates, and then only time will work normally, but only until I turn off my laptop. Once I turn it on then next turn, it passes through this new cycle of 45 minutes. If anyone has had this problem or knows how to fix?

    I'm not very good at explaining, but I hope you guys can help! I appreciate it really :) Show!

    If not, change it and don t forget to save the changes.

    In Control Panel--> Date and time--> time tab Internet, please uncheck the auto sync with the internet time server.
    In the other, called tab time zone please choose the right time zone and activate the tick to the option called automatically adjust the clock for an advance of changes

  • Satellite M100: BIOS time is incorrect

    I have a Satellite M100. Yesterday when I turned on my laptop clock sets time in 2010. After that I put the time, missing a few minutes or I went back an hour in 1-2 hours after that I have to reset the time.

    I checked the time window with BIOS using promt, but it's the same thing. I put DST correctly and because I'm using my United network it may be restrictions for me to synchronize the clock. I am using windows XP home.

    Please help suggest what I should do to stop my clock acting wierdly?

    Thank you...

    Hello

    I put t know if this will help, but please don't forget the battery CMOS is not empty. See s operating manuals and you'll find info, how long battery CMOS must be fully charged.

    If you are in permanent line be as safe as the time of the laptop will be permanent synchronize with internet time server. This option, you can find in the properties of Date and time.

  • Screen does not light after the start, but after standby on Satellite M100

    Hello
    I have some experience with computers and laptops, but this problem exhausted all of my knowledge.
    My girlfriend has a Toshiba Satellite M100, PSMA1E. He currently works on Windows XP, SP3.
    The laptop has always had problems closing/stand bye. He would stand bye and the screen would not. She would usually be manually turn off (holding the power button) and restart.

    Same thing happened last week, but with me. I turned off the power button but when I turned it on the screen was completely black. After a few attempts, I realized that everything worked; I could hear the usual audio files and XP Boot, but there was no way I could get the job of the screen.

    The strangest thing is that the CMOS/BIOS, one with the Toshiba logo settings screen, also does not appear. If it's an OS problem, I thought that I would be able to access the BIOS at least, but it does not work. FN + F5 does not work.

    Then, strange yet something happened. I was turning it on and off with keyboard shortcuts and I realized that if I put on stand bye using shortcuts and then go back on the screen turns on perfectly well (there is a cause of adjustment resolution icons are irrelevant, but it works perfectly fine).

    From that on I tried everything I know. Update the BIOS, all Windows XP updates, all Toshiba QuickFix, cleaning the registry with different tools, uninstall and reinstall the video driver (ATI Radeon X 1400) utility, shortcuts keyboard, power saver, tools hardware Toshiba, looking to start up programs, services, everything I could possibly think off.

    What intrigues me is that the Toshiba start screen will not be displayed. I can't access the BIOS, but I tried to restore the standard values of the BIOS with Toshiba hardware tools. It did not work. I don't even know if reinstalling XP will work because whenever I turn it on it is all black and I have to make the stand bye / Tower on Tower.

    When I have it plugged into an external monitor, I could see all starting the process (initial screen of the BIOS and Windows). I then tried to access the video driver display configuration but it would show only the external monitor. It would only detect the laptop screen after a stand bye / turn back on, and then it worked perfectly: the screen two screens simultaneously, extended, everything. Ah, changing BIOS selection automatic the LCD + external monitor does not work.

    I am really puzzled here and I can't understand it. I really don't think it's a hardware problem, because the screen works 100% after the stand bye. I guess that XP is do something during the closing down that completely 'stops' my screen, even after starting, and then I can only turn it on with the thing stand bye.

    Any help would be really appreciated!

    Best,

    Hi guys

    I had a similar problem on a series of Satellite A200 and I could solve works to update the BIOS and update the graphics driver.
    In addition, you must make sure that all available MS fixes and patches have been installed.

    Unfortunately, but that's all I can suggest. If the problem persists and you would not be able to solve update components then an ASP needs to check.

    Good luck

  • Satellite M100-233: stops right after the "XP" logo

    Hello
    I have a Satellite M100-233 with XP Home Edition SP3 (in Portuguese)
    When it is connected to the mains and the battery is not fully charged, sometimes the yellow light does not shine.
    Check the voltmeter application when this happens, tells me that the battery is on, the energy source is the sector, but the battery runs down.
    As I continue to use the laptop, the amount of the battery is reported as progressively less, until he tends to zero, then the laptop just turned off, as if she was not connected to the mains.
    Even if I start with the battery charged to 100%, after a couple of hours (sometimes more, sometimes less) the same thing happens.

    From an authorized dealer, they told me that it was probably a short battery shorted out.

    Get not that: * if she take the battery out of the laptop and turn it on:
    -Most of the time it turns off right after the "XP" logo.
    -It seems that this happens more often when the battery was fully charged the last time that I used it (strange! "I imagine this?)
    -Also sometimes happens after that I use the laptop for a while

    The only unusual bios message I get is "no TPM or TPM has a problem." I guess it has to do with the cryptographic protection, so I imagine that this has nothing to do with this issue.
    About two years ago, there was a problem with the battery (it ceased to be recognized as present by the laptop) which has been repaired under warranty: they told me that they had replaced the motherboard then. However, at this time there that I could continue to work normally without the battery, which is not the case now.

    I would be grateful for any advice. The most annoying is that this problem follows an irregular pattern, and the diagnosis, the dealer gave me seems hard to believe. As I use my laptop to collect data for research abroad, it is quite a risk for me to use it if I can't be sure when it will turn off on its own.

    Hello

    To be honest, I doubt that anyone here in the forum would be able to provide an exactly the answer to this question
    I think that it of almost impossible to say what's wrong without running any hardware checks.

    But to me it looks like a card mother number possibly it s power of electronic power supply which is part of the motherboard.

    What to say, maybe you need a new motherboard, but the new mobo is an expensive item, and in my opinion, you should first check if it is s to replace the motherboard or buy a laptop second hand for the same money.

    I tried to download the latest audio driver from realtek high defintion, but its still does not. Tried several restarts, System Restore, disable antivirus but does not yet.

    I don't know what can be the problem but the fact is that updates Windows update offers some drivers and, in general, you should not install their Mr. with other words, you should only use the drivers from Toshiba.

    What can you do now? Have you tried to reduce the OS to an earlier time (before installing updates) and check the functionality?

    One last thing. Software driver Sound should start with Windows, then please check MSCONFIG > startup if the sound software is listed and enabled it.
