Macbook 0 key problem - memory upgrade?

[maxlmac]

Hi all

Yesterday I upgraded my 5 month old Macbook from 1GB of stock RAM to 2GB of Crucial RAM. Using my Macbook most of yesterday and nearly all day today up until one hour ago was fine.

Having been using my Macbook since 7am this morning until about 7pm tonight (long stint!) it appeared that the 0 key had become stuck. After several reboots and power off and on's, the Macbook was repeatedly typing 0's.... like 000000000000000000000000000000000. I didn't however get the problem when using it in Clamshell mode straight after this happened.

I have just put my old memory back in and the problem appears to have gone away however I am thinking that this may be a co-incidence.

Any suggestions please?

Thanks so much!

It has to be coincidence from your having physically manipulated the machine, it can't be a RAM defect.

The key to it is it didn't happen in Clamshell mode when the keyboard was disabled, therefore it couldn't be OS, motherboard or RAM, it had to be a physical issue with the keyboard.

Hi

Thanks for that. I agree with what you're saying. I ran the Macbook with the old memory back in for about 30 minutes and the problem didn't come back.

I have since put the new memory back in and the problem appears to have gone away?!? The keyboard seems fine.

Incidentally, this is probably the longest period I have ever run the Macbook out of Clamshell mode.

Thanks again...
