    I recently tried to upgrade my Portege M400 laptop from the original 512 Mb of ram to 2 Gb (which seems to be possible according to the user's manual.

    I tried to install standard DDR2-533 memory (I am installing 2x 1Gb). However, when i tried to restart the computer with the new memory the hard drive didn't recognise the new memory and I had to get someone with more IT expertise than me involved. After I tried to replace the original memory back into the computer the hard drive also failed to recognise that and the laptop had to be restored to the factory settings before windows would load again.

    Can anyone tell me what kind of memory I should be installing? Is there Toshiba specific memory that should be installed in the system? And finally, can I just pick this up from any toshiba re-seller?

    Thanks

    Hello

    Without much writing I can post compatible memory modules for your notebook model:
    PA3499U-1M25(DDR2-667 256MB Memory Kit)
    PA3511U-1M51(DDR2-667 512MB Memory Kit)
    PA3512U-1M1G(DDR2-667 1GB Memory Kit)
    PA3513U-1M2G(DDR2-667 2GB Memory Kit)
    DDR2-533 256MB (PA3389U-2M25)
    DDR2-533 512MB (PA3412U-2M51)
    DDR2-533 1GB (PA3411U-2M1G)

    Your notebook can handle with max 4 GB RAM. If you want to order memory just use part number PAxxx.

    You can order memory module everywhere. Use listed part numbers given by Mike and you will find enough online shops in your country where you can order your favorite RAM.

    Bye
