I was wondering if some can help me figure out how to change the memory of Sony Vaio PCG-862A. I tried opening couple of slots in the back but couldn't find one for Memory. I currently have 128MB Chip and I know it supports upto 256MB.

    From what I can tell, the official model number of your unit is PCGXG500, and it takes 144 pin SODIMM PC100 SDRAM memory modules.  The largest such module listed that I can find is a 128 MB module, but the computer can hold two of these.  Also, there is some chance that you currently have two 64 MB modules, in which case you might have to replace them both.  Such a module can be expected to cost $25 to $50 (each).  The memory is apparently located under the keyboard (you should really go to the Sony web site to get this procedure complete with the photos).  Do not force anything, there is a real risk of damaging the keyboard.

       1. Turn off the notebook.
       2. Discharge any static electricity by touching a grounded metal object.
       3. Disconnect all peripheral devices from the notebook, including PC Cards.
       4. Disconnect the notebook from power and remove the batter

          IMPORTANT: Allow 2-3 minutes for the notebook to cool down before proceeding.
       5. Close the lid of the notebook.
       6. On the bottom of the notebook, unscrew and remove the keyboard release screw [FIG. 1].
       7. Open the lid of the notebook.

          WARNING: There is a risk of hardware damage. Do not attempt to pry up the keyboard anywhere but below the Fn and LEFT ARROW keys. Under the Fn key and the LEFT ARROW key, using a flat head screwdriver, gently press each of the plastic tab locks toward the front of the notebook.
       8. Use a small flat head screwdriver to gently pry the front part of the keyboard upward.
       9. Lift the keyboard and gently lean it against the LCD screen

          IMPORTANT: Ensure the keyboard cable does not become detached while lifting the keyboard.
      10. Remove the memory module from the packaging.
      11. Install the memory module by sliding the memory module [FIG. 2] into the memory slot.
      12. Push the uppermost edge of the memory module down toward the computer until the retaining clips click into place to firmly hold the memory module.
      13. On the top of the keyboard, insert the four tabs [FIG. 3] under the top of the keyboard slot.
      14. Lower the keyboard into place while ensuring the tabs remain locked in place

          IMPORTANT: Ensure the keyboard cable does not become detached while replacing the keyboard.
      15. Press Fn LEFT ARROW to ensure the keyboard locks into place.
      16. Close the lid of the notebook.
      17. On the bottom of the notebook, replace thekeyboard release screw [FIG. 1].

    144-pin, 256MB PC100 SODIMM memory is widely available. Crucial, Kingston, Viking, IBM and Sony all sell that part. Prices range from $59 on sale to $175 or more new. It is not cheap.

    Thank you. I was able to add another stick of 128MB but now some of the keys are acting up. What should I do?
