  • Satellite Z930 - after the update of the BIOS, additional RAM no longer works

    I bought my Z930 Satellite in August and installed 2 GB of additional RAM in it. Worked well, the Ultrabook detected and had total 6 GB of RAM.
    Yesterday, I stopped ignoring these messages from Toshiba Tempro and installed the BIOS update suggested that Bios 2.20 (not sure what version it was before). Now, I have several problems:

    * First *, my Ultrabook no longer starts with the extra RAM. I press the power button and then the power light flashes: yellow 2 times 1 times orange loop. The screen stays black and the CPU fan starts at the maximum level... Only when I remove the extra RAM, then it boots.

    * Second problem *, without my extra RAM, it starts, but sometimes with the fan from the CPU to the maximum level. I so restart it stops.

    * Third problem *, Windows doesn't detect only 2 GB of RAM. I have now no extra RAM mounted, it should detect the 4 GB of RAM, as when I bought it. Now, there are only 2 GB...

    So this is what happens when I install the proposed updates? -.-
    So, what can I do now? At least, I want my preinstalled 4 GB of RAm back. Is there a BIOS downgrade, or something similar to undo changes?

    Thanks for the final suggestions!

  • Installation of additional RAM in T500

    Basically, I got my T500 this year with an additional ram to complete the 2 GB, it comes with.  I know where the ram is and how to get there, but I'm confused about how the second ram card goes on top of the old.  The only video on the website lenovo shows a guy put in the first map of ram.  Any instructions on how the second card must be facing, a sign that it is connected, and I have to to see if my computer recognizes the new ram would be very useful.

    Thanks in advance.

    ajmack2,

    I'm going to assume that you now have only 1 module installed, a single 2 GB module in the lower slot.   The modules are memory clavetés so that they can really only go one way.  After removing the keyboard and palm rest, insert the new memory module in the empty holder.  Sometimes, there is a flap or little material there which partially obstructs your vision of the socket.

    The module goes into a corner and you insert in to the screen, then press gently downwards.   The holes at each end of the module must be aligned with the clips and they should snap into place.

    When you put together and restart, you can check that it's seen either by opening a command prompt and type "winver", or go in start-> my computer-> information system (on the left at the top of the page system tasks).  The general tab of the resultant pop up screen should show you how much memory is available.

    Note winver and control panel will report slightly different amounts.  With a 32 bit OS, you will see more 3 GB if, and when you run the integrated graphical mode, you can only see 2.5 GB in some cases because some is reserved for the video.

    Best regards

  • Laptop does not see additional RAM memory

    I just used satellite 2800-200 with 64 MB of memory on board, she also had 128 MB in memory but does not see it. I though that it was a problem compatiablety so ordered the new memory 128 MB ram pc100-sodimm Arch shows what that good memory for this machine, but he does not see this is y at - it something wrong with the motherboard or I missed something please help!

    Hi Paul

    As much as I know a lot of third-party RAM module are not recognized correctly. In my opinion, you should change it and check Toshiba or Kingston RAM module because this module are tested with Toshiba units. Otherwise contact the store you purchased this module and explain the problem to them. If they ensure that it works they must be able to give an explanation.

    I have Satellite 1900 and last year, I had a similar problem. To save my money, I ordered a cheap package and it was a bad idea. I sent it back and ordered from Toshiba. It was a little more expensive, but it works perfectly.

  • Additional licenses purchased in 2004, but they are not loaded on the server, and they can't find the hard copy of the licenses to load them in.

    Asked me to take over the COMPUTER Department of a small Christian school. They are running SBS 2003. They bought licences for additional client access in 2004, but they are not loaded to the server and they can't find the hard copy of the licenses to load them in. Also, they purhcased of XP Pro and Office 2003 licenses (I have the disks and keys to install but do not know how many licenses they own) and they are not either of the paper copy of these licenses. Is there a way to contact Microsoft to get the licenses? Any help would be appreciated.

    original title: recover lost Volume Licensing

    I just figured this out...

    I called the 1-866-230-0560 Option 3 Volume licenses and talked to someone who searched under the name of the school in order to locate licenses. It is even searched under our zip code and found other licenses that have been purchased by the school where the dealer abbreviated the name of the school.

    I hope that this is useful information to others in the same situation.

  • Satellite U920T - 11 c: how to insert additional RAM modules?

    Anyone know if there is a service manual for this model or a schematic representation inside this computer with the lid back.

    Thank you

    The memory of U920T satellite is not user upgraded. This means that if you do want to upgrade the memory, please contact an authorized Toshiba maintainer for assistance.
    In which case you would try to disassemble the laptop by yourself, you will lose the warranty.

    But to my knowledge the U920T Satellite series supports ONE slot memory and memory that one module (max 8GB RAM) can be installed. So even if you do not upgrade the memory, you are limited to 8 GB of RAM.

  • Y at - it a clear indicator or a code to indicate if a stick of RAM is registered or unbuffered? I would like to know for sure before installing additional RAM for this Mac Pro (2013). Thank you in advance. David

    Hello, all:

    Y at - it a clear indicator or a code to indicate if a stick of RAM is registered or unbuffered? I would like to know for sure before I add that extra RAM for the empty slots this Mac Pro (2013) that a 2 x 8 is installed.

    Thank you in advance.

    Post edited by: AppleHarvest (typo corrected)

    The 4 and 8 GB sticks are not saved while the sticks of 16 and 32 GB are registered. As you seem to know, you can not mix registered and unregistered sticks. For example, you can only add 4 or 8 GB sticks to your present 8 GB sticks

  • Satellite L30-105 does not recognize the 1 GB of additional RAM

    Hi there I hope someone can help me

    I have a Satellite L30-105 PSL33E, which came with 1 GB of ram installed (2 x 512 MB made by TeamViewer)
    and it's terribly slow with vista, not to mention programs.
    The toshiba website says max RAM is 2 GB, so I bought a Kingston 1 GB ram chip to increase the ram to 1.5 GB. I thought should try before moving to 2 GB

    However after installing memory vivid it's show still only 1 GB in windows and in the bios (894 + the rest for video). It has the latest available BIOS on the site 3.10, yet still does not recognize the chip.

    The chip is installed in the lower slot, including the original 512 at the top (closest to the keyboard)

    Are limited to only some of the Satellite of RAM?
    The old subjects indicate if kingston does not work try corsair.
    Other topics suggested to change slots
    Others suggest that it may have only two of the same ram chips in IE 2 x 512 or 2 x 1 GB, you may not have 1 of each

    Can anyone help? everyone knows about similar problems?

    I will not buy any more RAM to try different brands for the same issue to occur

    Hello

    The L30-105 is able to manage the 1024Mo modules in each location it should be able to update the RAM up to 2 GB.

    > Why the RAM 1 GB module cannot be recognized?
    Perhaps the two modules are not compatible with each other
    I would recommend using two identical modules of the same manufacturing
    I use Kingston modules, they are ok for me

  • Equium A100-147 - how to install additional RAM memory?

    Can someone point me to instructions on how to mount an extra internal memory for a satellite A100-147.

    Thank you.

    Hey Buddy,

    Upgrading RAM is quite easy: remove the battery and unplug the AC adapter. Turn around the laptop and remove the screw fixing the memory module cover and lift to it. Now you can insert a second memory module.

    Also, check your user manual. You will find more details and photos on this upgrade. It can be downloaded on the site of Toshiba, if you n t have more. ;)

  • Satellite L755-16U - BSOD with an additional RAM module

    Hello everyone.

    I bought my toshiba Satellite L755-16U nearly 4 years ago.

    This year I decided to buy more memory for my 4 GB,
    I bought Kingston SODIMM DDR3-1333 4096 MB PC3-10600 because they have the same characteristics. Since then occasionally

    BSOD began to take place. I don't know why.

    I checked my drive with chkdsk and checked my memory with memtest86 - no error.
    Separately, the two work well in different locations. I'm desperate.

    Should I buy another a kingstone and try to put in 2 kingstones memories or what should I do?

    Hello

    According to specifications of the laptop, your machine can handle with 8 GB of RAM, so you can use 2 4 GB of RAM modules.
    Compatible 4 GB of RAM has PA3918U-1M4G part number. Part number of Kingston for this RAM module is KTT - S3B / 4G.
    That's all I can say on the upgrade memory.

    Hi Peter,.

    I think the part number you need is PA2042U which you should be able to get from a Toshiba dealer in your area, or you may prefer Google for this.

  • Last updated by Satellite A100-289 with a new CPU and additional RAM

    Hello. Sorry for my English in advance :) I have a laptop Toshiba Satellite A100-289. Despite I am satisfied with the laptop, it is possible for me to update, so I have a few questions on this topic.

    Fact laptop support Modules-SO-DIMM 2 GB of RAM? Also, what mobile CPU is supported for upgrade? Is it possible to replace the Core 2 Duo T5500 (default), with a few other Core 2 Duo processor, such as T7400, T7600, T7700? And if I install a new processor, it will influence the energy consume and warming temperatures drastically?

    Thanks :)

    Hello

    with regard to your question: Yes you can.
    Usually your chipset is capable of a maximum of 4 GB of RAM, but due to the limitation of the slots (Slot 1 cannot handle a 1 GB module), you can move only to 2 GB maximum, because your machine has only 2 slots.

    And what with your CPU? You can certainly try, but you won´t have a lot of luck. Excluding the small fact that each machine has it s own system of cooling for the processor which is equipped with this machine.
    the won´t CPU run at full speed.

    Why not? The problem is and now speak from experience;) that when you replace the processor in a processor intel pentium M or Core(2 Duo) system, something in the bios change, then the new processor
    will not properly recognized. And then the old? Nope. After you swap the CPU, you will have to bring your machine to an ASP.

    They have software that reactive something in the BIOS and the CPU runs at full speed. Since then they to the ASP will notice that you tried to Exchange something in the Board of Directors,
    you will face a cancellation of the guarantee and you will have to pay for everything that happens to be broken after the revocation.

    So I propose: update your RAM, but don t touch your CPU.

    Have a nice weekend
