A quality laptop computer memory can increase your computer performance. 

Generally, you can find laptops with SDRAM or DDR-SDRAM memory.

You must find out the type after which you need to explore internet to find a right supplier of different types of laptop memories. While buying a new memory module, it is better to pay attention to the existing memory modules of your laptop as it helps in determining the module you need to buy. This can easily be done just by opening and having a look in your notebook. The other relevant information can be found by reading the manual.

one of the most important things to consider before installing new memory module is the memory capacity of your notebook. It is important because there is no point in buying a memory module of 1GB if your laptop doesn’t support a module higher than 512MB.

Memory Module
Purchase a compatible memory module from your nearby electronics retailer, from an on-line store or directly from your laptop manufacturer. I would advise the latter but that is not always necessary as long as you ensure compatibility.

Installing the New Memory Module
Hold the new module by its corners edges, line up the slot key notch of the module with the slot key of the port and insert into position. Pushing on it lightly will automatically lock the ejector clips and the module should be firmly in place.
