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?

Re: Toshiba a105-s101 memory install boot issue

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.

Re: Toshiba a105-s101 memory install boot issue

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.

Re: Toshiba a105-s101 memory install boot issue

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..

Re: Toshiba a105-s101 memory install boot issue

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)

Re: Toshiba a105-s101 memory install boot issue

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.

Re: Toshiba a105-s101 memory install boot issue

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

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:

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 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
