One Ram slot not now recognised.Checked by switching ram strips one being 512 other 256.One slot recognises both one neither.Any suggestions on a solution.Am at present in India where believe you me the supposed experts arnt always experts.
I have the same problem. I called IBM and they said they would fix it for $475 about three months ago. I assume that included labor. I also have a problem where the laptop is extremely picky about booting up cold when on a dock (tried two different ones), but if I boot it on battery then place it on the dock it usually is ok.
This is a common problem with all thinkpads. The issue is caused by a blue case bumper pushing down on the reverse side of the memory slots and the memory door/cover. The memory cards will put uneven pressure on the solder joints causing cracks. There was a engineering fix offered to t30 owners under warentee. This fix was a motherboard swap out and a new memory cover with the proper distance needed. Since thinkpad is now owned by another company (lenovo) You may have issues getting the laptop fixed.
I had to purchase a new motherboard to fix mine. You can also send your machine in to a repair shop to have it reworked by hand but it usually costs about the same. (200$USD was how much I had to pay.)

Just put in one memory card in the first slot and see if recognised. Then try the other in the same slot . If both ok then try the second slot and see if that too recognises both ram sticks. If the sencond does not recognise either stick then the slot is at fault.
it sounds to me that you have parallel port memory. This means that you have to have the same, ie both stick being 1gb, or 512mb. I just fixed my aunts pc and she was having the same problem . once I installed both 512 sticks it recognized both. ^_^ hope this helps. good day
Are you sure its the correct speed/type of RAM? According to Google your laptop takes PC2700 DDR RAM, ensure you are using this in both slots to avoid problems. If you have it fully inserted into the slot and nothing happens when you swtich it on then the laptop doesnt like that type of RAM and you'll need to change it.
There are 2 possibilities here - either the slot is not working or the RAM itself.
First install the working 128MB RAM in both memory slots one after the other and ensure that both the slots are in good shape.
Next, install the other 128MB RAM in one slot and check if this is working good.
Your laptop can support a maximum memory of 512MB. If you looking for an upgrade, please call Dell Support. Even though it's little expensive and shipping takes a week, you can get a free after sales service and peace of mind. Moreover you get proper guidance from the experts.
Hi, I am assuming that the original piece of memory was a 256mb ddr pc2700/333mhz ?
i have looked at your board on the product maker website and it supports memory to 2gb of pc2100,pc2700/pc3200 type memory. Be certain however that the new piece added is the same clock speed as the original that you are trying to use with it. You cannot mix clock speeds, either pc will not boot or it will only recognise the compatible piece. Have you tried booting with just the new piece 9 leaving out the older piece)if yes what was the result. Need more help ?? firstname.lastname@example.org
This is likely a memory timing incompatibility. You can go into the BIOS settings of many motherboards and set the timing specifically for each RAM slot, but without knowing exactly which piece of RAM you have I can't tell you what to set it at. You could use the utility CPU Z, install one stick, run the utility and write down all the memory information, then install the other stick and write it down too. Then go into your BIOS and see if you can set all of your specifications to match the memory.
Of course if you could find someone to swap sticks with that would be easier. Some motherboards are more picky than others about which sticks they work well with, name brand manufacturers are more picky than aftermarket in general.
