Toshiba a105-s101 memory install boot issue

Hello, my notebook had two 256MB memory modules installed. I purchashed 1GB and upgraded one slot(for a total of 1.25 GB..everything was fine. Today I bought another 1GB, but when I installed that..the computer would not boot..the power would come on but it immediately powered off and on 5 times before completely shutting down.

What is strange is that neither 1GB module will boot by itself in either slot unless the other slot has the old 256mb of ram installed. So I know both 1GB units are working. I just want my 2GB ram! lol...Anyone ever heard of this?

    Thanks, it does support 2GB though..even the Toshiba website specs say so. Either 1GB stick works with the 256MB stick (for a total of 1.25GB).

    I am having the same problem. I bought 2 gig of Crucial memory for my Satellite A105. When both 1 gig modules are installed, the computer power light blinks on and off repeatedly, but never boots up. But either of the 1 gig modules, installed with one of the original 256k modules works fine. The computer specs say that the memory is expandable to 2 gig. Toshiba tech support pages do not address this problem. I called tech support, but they wanted to charge me $35 since i'm out of warranty.



    I thought it might be a problem with Crucial memory, but then I saw another forum where someone reported the same problem with their Toshiba satellite laptop when they tried to install 2 gig of PNY memory.

    having the same probelm upgraded to 2 gb and blink 5 times and shuts off i even went out and got a 512mb one to see if i could get 1.5gb but same probelm any solituion would be much appecaited i did reAD ON THE WEBSITE THAT THE COMPUTER CAN HOLD 2GB in a slot so maybe i should go try a 2 gb card but all the site remember and sell only 512 and 1 gb cards for this computer

  • ApolloMan Jan 04, 2008

    I have a A105-S2061 and just purchased 2 sticks of 1 gig from Crucial. The computer came with a 256m stick in slot 0 and I had installed a 512m stick in slot 1. Works fine. Will not boot in any combination of the 4 sticks unless the original 256m is in slot 0. Currently the 256m and a 1gig stick are installed, Windows reports 981meg installed. I'm not a math whiz but when I went to school 1024+256 did not equal 981. I'm glad I'm not the only one, I though I was losing my mind.

  • tsansan Feb 02, 2008

    I have the same problem... original ram was 256MB, bought another 256MB at time of laptop purchase about two years ago. Recently, bought 2-1G Kingston RAM. Both of them work as long as the original 256mb module is inserted in slot. Can anyone solve this problem?

  • Anonymous Jan 07, 2009

    Same problem here, trying to use 2x1gb but wont boot, 1x1gb won't boot either. The original 512mb + 1gb = 981mb.
    My 1gb's are 666mhz, which I think might be the problem.

    Did u guys used PC
    4200 memory sticks? Cuz i think the problem here is all about
    frequency, since when u use the original memory together with the new
    one the system gets the memory frequency down to keep up with the
    original one.. wich is 533 or PC4200. You guys must be using ddr2 667
    Pc 5300 memorys..

    I bought 2 Kingston 1 GB DDR-2 533 sticks today and the BIOS is now reading 1177776 KB instead of 960 MB. Happy with at least the 1 GB + for now. Canot boot with both new sticks installed. Using 1 GB and a 256 MB. Not finding PC4200 anywhere locally.

The RAM must be PC4200 Kingston KTT SODIMMs or it won't work. I currently have 2x2GB in my A105-S2001 and all it does is not read a little over one GB.

Hi hidoy,

Ref: Toshiba a105-s101 boot up --- Am convinced that memory speed is the problem. I must use 2 PC-4200 sticks or live with the mixed memory presently installed. Board is incapable of down-clocking higher speed ram as a substitute.

Same issue: tried the PNY PC2-5300 1GB modules and they will not boot individually, only while another stick is present (in this case, the original 256 Samsung)

Matt67, I really think you must have got lucky because I tried pny in my toshiba a105-s101 and no luck. so i thought i would try it with the better kingston memory and still no luck. this is obviously a issue with these model toshiba's but no one has the answer. I have the latest bios and there is no way of getting into the bios when the pc is not even booting up.

Okay guy i actually have the solution i had the same porbelm but now i have 2 gb or ram and my satellite rock now okay first the ram you bought is wrong and not compatible what you need is kingston ram with the same specs trust me i bought the centon stuff and call everywhere trying to get this to work i had toshiba sell me some kingston and rolled my eyes as i put it in but i powered it on and bam worked like a dream so if you want the 2gb you have to fork over the 29.99 each and you will be much happier

  • matthew scaman Sep 14, 2008

    if you guys buy a set of 1 gb sticks from kingston they will work but you have to go online and buy a exact pair as these are very picky i have done this to three satellites not all the same model but mine was the first one and is this model what i did was when to toshiba website and went to the upgrades avaliable it sent me to the kingston website i bought the 2 gb set which is 2 1gb sticks and now i have 1.87gb of ram this has nothing to do with bios kingston has a guarntee of compatibitly so if you bought kingston memory and it was right then you need to contact them as i have said two other people in my family have satellites not the same model but they had 2 gb limits and they now have two gb of ram all in all the kingston memory was 30 dollars a stick so a total of 60 dollars spent and this is the only way do get 2 gb out of these laptops it wasn't luck or some sort of magic just go to the website buy the memory from kingston that they say to making sure it is a set of two identical stick made together from the same batch and they will work no probelm

Check your owners manual to see if the laptop will support 2GB of ram. If not you will need to use 2 512mb sticks to get to 1 GB

    Make sure the memory you are adding is of the same type as the memory that was orginally installed. Such as PC2100, etc, DDR or DDR2 and of the same frequency. If the new memory is of compatable type, but still does not work, contact the support section of Tosiba's website. BPCS

IBM T23 wont turn on after adding new RAM


Hi - according to memory suppliers your T23 has the following memory capacity / requirements:

  • IBM ThinkPad T23 maximum RAM capacity: 1GB
  • Your IBM has Two (2) memory slots or sockets
  • Module upgrade PIN count is: 144-PIN
  • The memory speed is: SDRAM 133MHz, PC133
  • The laptop DIMM type for the ThinkPad T23 is: SODIMM, SO-DIMM, Small Outline DIMM
  • Non ECC

If you are meeting these requirements, you may have a defective module.

Also, according to Lenovo's page on the machine:

Memory
The system has 128MB or 256MB of memory standard and can be configured for up to 1GB of addressable memory. Memory options up to 512MB SDRAM SO DIMMs each can be added in the two available slots for memory expansion. The standard 128MB of memory is expandable up to 640MB and the 256MB of memory is expandable up to 768 MB of addressable memory with 64, 128, 256, or 512MB SO DIMMs without removing the 128MB SO DIMM that is standard in one of the internal slots for memory. For customers that need the maximum 1GB to which memory can be expanded, it is necessary to replace the 128MB or 256MB card with a 512MB card plus add another 512MB card in the extra slot. Only 133MHz DIMM memory can be used in this system. The use of 100MHz DIMM memory is not supported in the T23 systems.

This means yo can trouble shoot the 512MB modules individually by installing one of the original 128MB modules and one of the new 512MB modules (for a total system memory of 640MB). If it does not boot, try again with the other 512MB module. This will help you identify a defective module that may be preventing the machine from booting.

I hope this helps & good luck!

System can not see memory upgrade


Are you sure the memory modules are compatible with your laptop?
You can try booting and going into the Bios (F2 or Del), sometimes that helps in reconfiguring the new setup.

When i try to boot my toshiba a75 laptop i receive a boot last good ... it won't boot i removed memory module i installed 2 yrs ago and it boots ... i purchased new memory module and get same error- it...


Below are the specs to the type of memory that can be installed in the A75...it is very specific and cannot be anything else then what is listed. You have 512 mb built onto the motherboard, with one expansion slot. That slot can only hold up to 1 gb stick if the BIOS has been upgraded. Go to Toshiba support and make sure the BIOS on the machine is up to date so it will accept the larger stick of ram memory and make sure all the specs are right on the stick that you have.

Each memory slot can hold DDR PC2700 with a maximum of 1GB per slot.*

  • Maximum Memory: 1536MB
  • Slots: 1 (1 bank of 1)
  • Standard Memory: 512, 768, or 1024MB (512MB non-removable)
  • USB Support: 2.x Compliant

    Adding memory to a a75-s211


    How much memory did it have before you removed the 256Mb RAM?
    If it had 756Mb RAM then the memory in the laptop has 512 Mb plus 256 Mb RAM modules, the 256Mb in the slot you can see and possibly 512Mb in a slot under the keyboard or soldered on the motherboard.
    Therefore by removing the 256Mb and replacing with 1Gb memory module will give you a total of 1.5Gb

    Memory Upgrade problem


    You have the correct memory, however, did you replace memory in both available slots with same capacity/clockspeed sticks? The below is from the Spec sheet for your computer.

    512MB(min)/2048MB (max), 2 memory slots using 256MB, 512MB, 1024MB or 2048MB PC4200 DDR2 533MHz SDRAM,
    dualchannel support requires two memory modules of same capacity and clockspeed
