    What type of Laptop do you have?

    Adding memory means remove the back of the laptop
    insert the mem to the slots. Thats all.


  • dukyana May 11, 2010

    Usually the memory cards slot into the motherboard.



    What model is your machine and is it a laptop or PC?

Hi The memory on the laptop is housed on the base.

You unscrew the correct cover, then a gentle click should remove the old memory card and you can insert your own ones.

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!

Emachines T5082 Adding 512Mb ram. Getting slot 0 installed slot 1 not installed.


Try swapping the memory in the two slots. It sounds like either one of the memory chips is bad or one of the memory slots is bad.
If you find that one of the slots is bad, then you might try just putting a 1GB Chip in the slot that works.

Hi there
Your t1090 will only accept a maximum chip size of 256Mb and so it will not accept the added the 512mb chip as it cannot handle it. 512 is the maximum size of RAM for this machine but unfortunately you cant put it in in one go

Adding computer memory


The only thing you could do is put in a 256MB module in the slot that you have access to. Only one socket is user upgradable. The second socket is only upgradable by a Dell service center. They would have to install a second 256 module to get you to the 512MB max.

Sharp Actius AV18 does not recognize added 512MB PC2700 RAM. The machine still only sees 256MB. Is there something else I need to do?


I assume the laptop had originally 256Mb RAM and you put 512Mb RAM in a the spare memory slot and you expected to see 768Mb of memory, is this correct? Try removing the 256Mb memory module and insert the 512Mb memory module and see if the laptop boots up with 512Mb of RAM. If it doesn't boot up then the RAM is either incompatible or faulty. Try using RAM modules from the same manufacturer.

1gb shows 512mb only


Your mobo is quite old and its chipset can only support a maximum of 512MB PER SIDE (technically called a bank) of a memory module. I would guess that your 1gb memory module has 8 chips that are all located on one side of the module, putting all of the 1 GB on one bank. Thus, only 512MB of your 1 gb RAM is detected and usable by your motherboard (the remaining 32 mb is most likely being used by your onboard video). You'll need to find a double sided 1 gb memory module (usually 8 chips on each side).

Adding memory to tx pro mainboard


You do not say what memory you are trying to install.

The ASUS P4S800D motherboard has four memory slots that hold DDR PC2700 or DDR PC3200 with a maximum of 1GB per slot, so the installed maximum is 4GB.

DDR memory is generally available in 128MB, 256MB, 512MB and 1GB modules. If you already have memory installed, it must be at least 128MB so you cannot add modules to 'bring memory to 128'.

Either you have a different motherboard and posted in the wrong section, your memory calculations are wrong, or you have used older PC-133,PC-100 or PC-66 memory instead of DDR. The last is unlikely as older SDRAM has two notches and won't physically fit into a DDR slot that only has one notch.

Please re-post with the specific motherboard model just to confirm and a list of the memory modules you are trying to use.

Installed 2 512mb ram but only shows 512mb


1. Reinstall both memory modules

This means take them both out and stick them back in firmly.

This is called ( reseating the memory )

If this fails have the memory modules tested or RMA the defective memory module.
