I am running Windows 7 Professional x64 on a Lenovo N500 42336BU machine. I would like to know the maximum capacity of ram I can install on it.
4 GB max, you should just paste the model number into google, the result comes right up. But yes.. 4GB max on that unit.
Crucial.com says the Lenovo 3000 N500 series laptops max out at 4096 MB (4GB) of RAM
You can get to this page by using the pull-down menus at Crucial.com homepage to select your PC's Manufacturor, Product Line, and Model.
Alternatively, their scanner will automatically detect your computer type and tell you which RAM slots are available for upgrade. Seems to only work with IE, though.
