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!

RAM upgrade


(1) flip the Notebook/Laptop PC over - see Fig.1 below
(2) find the memory cover - it really easy to find in this photo.

12_5_2011_7_39_30_am.jpg

Fig.1 Toshiba M35X bottom view - the memory cover is seen at center left and secured by a single screw.

(3) remove the (1) screw securing the memory cover.

12_5_2011_7_42_34_am.jpg

Fig. 2 Toshiba M35X laptop shown with memory cover removed and HDD (Hard Disk Drive) removed, and with the HDD cover flipped up.
The RAM (SO-DIMM boards) are visible at center left.
The HDD cover is seen at the bottom of the photo.

(4) Using proper anti-static/static control techniques, clip alligator clip or your anti-static wrist strap to a frame ground of the laptop at an I/O connector or frame ground under the HDD cover.
(5) carefully remove (2) old 256 MB SO-DIMM DDR333 memory modules.
Store old memory boards in the anti-static plastic baggie in which the new memory boards were shipped.
(6) install (2) new 1GB SO-DIMM DDR333 boards, for total of 2GB of system RAM.
(7) reassemble system, and boot OS (operating system).
The laptop's ROM BIOS will auto-detect the new RAM and begin a standard POST (Power-On Self Test).
(8) If OS is MSWindows, it will also auto-detect the new memory, and allocate it to application software.

The technology of the Toshiba Satellite M35X-S349 memory module is called
DDR333, meaning DDR (Double Data Rate) SDRAM (Synchronous Dynamic RAM), at a memory bus speed of 333 MHz.
The Form Factor of the DDR memory card is SO-DIMM, which stands for Small Outline DIMM (Dual In-line Memory Module) (see photo).
Reference: http://en.wikipedia.org/wiki/DDR_SDRAM

Fig.3 Each 1GB SO-DIMM DDR333 memory module will look like this one.
The Toshiba Satellite M35X-S349 supports a maximum of two SO-DIMM memory modules.

Each memory module can hold (a) 256MB, (b) 512MB, or (c) 1GB,
in the SO-DIMM Form Factor compatible with the Toshiba M35X-S349 Notebook PC.

Samsung n150 plus is expandable to how many memory?


The Samsung N150 Laptop comes installed with 1GB of Memory and can be upgraded to a maximum of 2GB Memory. This computer has 1 (one) SO-DIMM memory slot, so to upgrade to 2GB of RAM, you will need to replace the installed RAM module with a single 2GB PC2-5300 DDR2-667 200pin SDRAM SO-DIMM memory module.

If you find this solution helpful, please leave a positive rating!

Hi,

This laptop has its own graphics card that doesn't rely on system memory for the graphics.

There should be no reason why its not detecting all 1GB of ram that you have installed.

Open the ram cover and make sure that you have clipped the ram into place properly.

I want to upgrade the ram in my IBM thinkpad R52 laptop. Do I have to buy DDR1 or DDR2?


You have to buy DDR2. The compatible memory is DDR2-533 PC2-4200, 200p SODIMM, 1.8v

To install the memory, follow these steps:
  1. Turn off the system; then disconnect the ac adapter and all cables from the system.
  2. Close the system display, and turn it over.
  3. Remove the battery.
  4. Loosen the screw on the memory slot cover; then remove the cover.

    If the SO-DIMM is already in the memory slot, remove it to make roomfor the new one by pressing out on the latches on both edges of thesocket at the same time. Be sure to save it for future use.

    58899bc.jpg

  5. Find the notch on the side of the SO-DIMM.
    Note: To avoid damaging the SO-DIMM, do not touch its contact edge.
  6. Withthe notched end of the SO-DIMM toward the right side of the socket,insert the SO-DIMM into the socket at an angle of about 20 degrees (1);then press it firmly (2).

    56bb48e.jpg

  7. Pivot the SO-DIMM downward until it snaps into place.
  8. Make sure that the card is firmly fixed in the slot and does not move easily.
  9. Replace the memory slot cover by aligning the back side of the cover first and then tightening the screw.
    Note:When you have added or upgraded a memory card, do not use your systemuntil you have closed the cover. Never use the system with the coveropen.
  10. Put the battery back in place, turn the system over again, and reconnect the cables.

To make sure that the SO-DIMM is installed correctly, do as follows:
  1. Turn the system on.
  2. Whilethe "To interrupt normal startup, press the blue Access IBM button"message is displayed at the lower-left of the screen, press Access IBMbutton.
  3. Select Start setup utility.
  4. The BIOS Setup Utility screen appears. The "Installed memory" item shows the total amount of memory installed in your system.

    For example, if your system has 256 MB of memory and you install a256-MB SO-DIMM in it, the quantity shown in "Installed memory" shouldbe 512 MB.

The compatible memory can be purchased here online.

Reg ram upgradation


Each memory slot on the C555NR can support a maximum of 1GB of RAM. There are actually 2 slots, but only one is easily accessible to you. By upgrading both the primary and secondary DIMMs, you could achieve a total of 2GB of memory but you would have to remove the 512mb chip that is already installed and replace it with 1GB (+1GB in the expansion slot as well.)

If you don't plan on taking the computer to a professional to be serviced, you will probably only want to upgrade the memory in the secondary slot located under the memory cover on the underside of the computer. It can handle a 1GB SODIMM.

FYI the memory is:
200 Pin DDR2-533 PC2-4200 SODIMM

Good luck!
