Upgrade memory for Satellite Pro L20

I use a satellite L20 pro - PSL25E. That this PSL25E means in terms of satellite pro L20 - 102 until xxx. On the support site to keep just the numbers but not this alphanumeric expression. I need this in order to select the upgrade module suitable.
If this can be answered, could someone tell me which module to upgrade should I choose in addition to the existing 512 MB?
Thanks in advance


It of nice that you have found the laptop model after your own investigation.
However, in my opinion the portable Satellite Pro L20 all support the same kind of memory, if it s L20-259 Pro or Pro L20-174

The units are supported on these modules:
DDR2 400/533 256 MB (PA3389U - 1 M 25)
512 MB DDR2-400/533 (PA3412U - 1 M 51)

  • Upgrade memory for Satellite Pro L20 problem

    I buy a 1 GB, 200-pin SODIMM crucial (marked on the module as 1 GB 2Rx16 PC2-4200 s-444-12-A0) and added to the existing module 256 MB (marked as 1Rx16 256 MB PC2 4200 s-444-12-C3)

    I can't get the 1 GB module memory I bought the work with the existing 256 MB module. The PC will recognize the 256 MB module in each slot and it will also recognize 1 GB memory module in the other location. However, when both modules are installed the PC doesn't recognize any order they are installed in the module 1 GB. The essential tool memory online seems to think that a slot is empty when it scans the laptop, even if both slots are filled. The BIOS also reports that only 1 GB is present when both modules are mounted.

    No idea how I can get the two recognized modules?

  • Upgrade SSD for Satellite Pro A120

    I have a satellite pro A120, which feels a little tired. I did research SSD upgrades to replace the HARD drive, but I don't know if I can update or not. I would really appreciate any advice or information you can give me.

    Thank you


    You can upgrade the laptop with an SSD. You need a disc SSD SATA 2.5 as the A120 supports the SATA controller.
    Not quite sure about the SSD size but I guess a 250 GB should be recognized correctly.
