stephmayes Posted April 18, 2007 Report Share Posted April 18, 2007 I have an IBM thinkpad T20.I have recently upgraded the memory from 128 x 2 sticks to 2 x 256 sticks. Having installed the memory sticks into the only 2 slots I have. The laptop worked fine for about a week. Then it started crashing and freezing occasionally. Then Microsoft error messages were coming up, when a report was sent, it said one of the device drivers were faulty.Then another microsoft error report said some hardware was causing the problem.So I remembered about the memory installation. I have now took one of the 256's out and it seems to be working fine without error messages or freezing up.Is there any way i can interrogate the system and establish if the actual slot is working as I have tried the 256 that is working now in the suspect slot, the machine just beeps at me without booting up.Does anyone have any ideas ?ThanksSteph Quote Link to comment Share on other sites More sharing options...
Scarecrow Man Posted April 18, 2007 Report Share Posted April 18, 2007 Try each memory DIMM seperatley. If it works, then try them in the other slot seperatley.I was just checking http://www.lenovo.com for your computer and I was presented with some choices:Brand: NotebookFamily: T20Type: this is where I get lost. The choices are 2647 and 2648Model: about 50 different models after selecting the Type.Is there any labels on your computer that show this information?

stephmayes Posted April 18, 2007 Author Report Share Posted April 18, 2007 SCM,Its a 2647..I tried the memory stick that works in the 'other' slot, all that happens is the laptop fails to boot up, screen remains black power button is on however it just bleeps at me.when I swop it, it works in the other slot..when i put the dodgy memory stick in the 'working 'slot it again does the above..blank screen, bleeps at me...Do you think its the slot thats not working ? Are they repairable ?thanks..as always, you are spot on to reply to my pleas !Steph Quote Link to comment Share on other sites More sharing options...
Scarecrow Man Posted April 18, 2007 Report Share Posted April 18, 2007 Sometimes computers are quite picky. If there is no RAM in DIMM0, the computer does not work. Therefore my above suggestion may be useless.Let me see if I understand what you're saying.Memory stick 1 works in slot 1.Memory stick 1 does not work in slot 2.Memory stick 2 works in slot 1.Memory stick 2 does not work in slot 2.Memory sticks 1 and 2 do not work together in either configuration.

Boris Posted April 18, 2007 Report Share Posted April 18, 2007 Do the 2 x 128's still work ? Quote Link to comment Share on other sites More sharing options...
stephmayes Posted April 19, 2007 Author Report Share Posted April 19, 2007 Boris,Cant put the 128's back in coz I sold them !SCM,Memory stick 1, doesnt work in either slot.Memory stick 2, works in one slot, not the other.Steph Quote Link to comment Share on other sites More sharing options...
Scarecrow Man Posted April 19, 2007 Report Share Posted April 19, 2007 OK Here is my thoughts.Memory stick 1 is bad.Memory stick 2 is fine, but it will only work in slot 1 because often computers require memory to be installed in slot 1, before looking in slot 2 for expansion memory.
