Memory

2007-12-05, 0:07 AM
I previously had a Thinkpad T40 and now have an R61i.  My T40 is no longer running but as far as I know, the memory is good.  Is it possible to use the memory from my T40 and add it to my current laptop?

Welcome!

The T40 used PC2100 DDR memory. The R61i takes PC2-5300 DDR2 memory, a quite different beast. The good news is that GB for GB, DDR2 memory is generally cheaper!

Thanks for the answer.  Obviously I am a novice about these things.  Is it difficult to install more memory?  I have 2GB and I think I can add up to 4GB

One of the neat things about Thinkpads is that there's something called a Hardware Maintenance Manual (HMM). In it, you will find information about what parts are in the laptop, how the system is put together and how to take it apart (if you ever need to; consult your warranty service first!). The HMM for the R61i is here:

ThinkPad R60, R60e, R61, R61i (14.1 inch and 15 inch standard screens)

Well, having said that, I just tried downloading the .PDF file and I can't seem to get to it at the moment. For some more information about memory upgrades, consult this page:

How to determine if your computer can hold additional memory - Notebooks

The memory sticks are right under the touchpad. They are not that difficult to get to. Just follow the HMM once you can get it.

Also, unless you have a 64-bit OS, you should not put in more than 3GB. The 4th GB will be 'invisible/unusable' under normal circumstances.

Re: Memory

Has anyone managed to do this - upgrade memory on a R61i? The diagram in the hardware manual indicates you remove screws then push in at the top left and right of the palm rest and remove it, but after spending over an hour trying everything I can think of I've not made any progress at all. My fingers just hurt! I'm assuming there is some trick, can anyone help? Thanks!

You remove the screws and lift up at the corners of the palm rest near the Fn and right arrow buttons. Make sure you have all the screws out that have a memory symbol next to them.
