How to Upgrade RAM Memory of the Lenovo IdeaPad S10-3 Netbook – a Complete Guide


A computer memory upgrade is often the best way of increasing overall computer performance, and upgrading netbook memory is often one of the easiest computer upgrades. Do you want to get a little more power out of your Lenovo IdeaPad S10-3 Pine Trail Netbook? Upgrade that 1GB memory module with a 2GB SODIMM. It will speed up opening new applications, running multiple applications at once, and switching between software applications (multi-tasking). Here’s a complete and easy guide on how to upgrade your Lenovo IdeaPad S10-3’s memory.

Purchase the right memory.

Intel Atom N450 (Pineview) based machines can’t access more than 2GB of RAM in total. A 1GB memory module is installed in the memory slot at the bottom of your computer. There is, however, only one memory slot on the motherboard, so this means that you’ll have to remove the current RAM module in order to insert a new one (*). For your Lenovo IdeaPad S10-3 you need a standard 200 pin DDR2 SODIMM laptop memory module (not desktop memory). Select a 2GB DDR2 SODIMM memory module of 667MHz or 800MHz. These may be referenced as PC2-5400 or PC2-6400. Recommended brands include, but are not limited to, Crucial, Corsair, Kingston, Patriot, and Viking.

(*) Note: according to the S10-3’s manual you have to replace the current 1GB SODIMM. Older 1GB S10 models sometimes had 1GB of RAM soldered onto the motherboard and the memory slot at the bottom of the machine was actually empty. We assume Lenovo doesn’t use that system for the S10-3, but have no confirmation of this yet. Check if the slot is empty. If it’s empty, you can just put a 1 GB DDR2-667 SODIMM module into the empty free slot.

  • A 1GB memory module is installed in the memory slot at the bottom of your computer. There is, however, only one memory slot on the motherboard so this means that you’ll have to remove the current RAM module in order to insert a new one. The procedure to replace the memory is described below.

    1. Shut down the computer completely.

    2. Power off your Lenovo IdeaPad S10-3 if it’s on. Also, unplug the AC power adapter.

    3. Prepare your IdeaPad S10-3 by placing it upside-down on a flat surface with some form of soft padding. Static electricity can damage your module and other computer parts. Make sure that you are working in a static-safe environment. Remove any plastic bags or papers from your work space.

    4. Remove the battery. This will prevent you from accidentally shorting anything on the system board during this process. Unlock the manual battery latch [1]. Hold the spring-loaded battery latch in the unlocked position [2], remove the battery pack in the direction shown by the arrow [3].


    5. Discharge residual power by pressing the power button.

    6. Be sure to ground yourself. Touch something metal (like a tap) for a couple of seconds and you should be fine.

    7. Remove the Hard disk/Memory/Mini PCI Express Card slot compartment cover.
    a.     Remove the screws that secure the compartment cover [1].
    b.     Remove the compartment cover [2].

    8. Press outwards on the latches on both edges of the socket at the same time, remove the SO-DIMM. Be sure to save the old SO-DIMM for future use.

    9. Most memory will be sold in a piece of hard, clear plastic. Gently remove the new module from the packaging by pressing on it from the plastic side. Avoid bending the module or applying too much force to the packaging. When you remove the SODIMM memory module from its packaging hold it by the edges, try not to touch the gold colored contacts as this can damage the memory.

    10. Turn the module so the teeth are facing the SODIMM slot and the sticker is face down. It’s impossible to put the memory module in backwards thanks to the notches which “key” it with the slot. Insert the notched end of the SODIMM into the socket. This is important; you want to stick in the new memory module at a 45 degree angle. Press the SODIMM firmly, and pivot it until it snaps into place and the metal retaining clips clasp into the grooves on either side of the module.

    11. Make sure that it is firmly fixed in the slot and does not move easily. If the memory does not fit easily, take it out and try again. The module should be seated so that you don’t see any of the gold contacts.

    12. Test it. Before you close your case, replace the battery. When the battery pack is inserted, it will automatically lock. Turn your computer back on. The BIOS automatically detects the amount of memory in the system and configures CMOS accordingly during the Power-On Self-Test (POST) process. There is no hardware or software (including BIOS) setup required after the memory is installed. You should see the new amount of memory displayed on your start-up screens or in the properties for “My Computer”. You can also Hold F2 during startup. The BIOS Setup Utility screen will open and the System Memory item shows the total amount of memory installed in your netbook.

    13. If everything works correctly, you are done and you can reinstall the memory compartment cover. If you have any problems, go to step 14 for troubleshooting tips.

    14. Troubleshooting. If you have trouble with your new RAM, check these things first. Check the power cords. Is everything plugged in properly? Check the module. Try removing the module and replacing it to make sure it is seated properly in the slot. If you’re still having difficulties with your RAM, check the Crucial FAQ section. You may find an easy solution for your problem.
