When your laptop starts acting slowly, you should consider installing new memory in it. Be sure, though, that you have the right kind of memory before installing it in your laptop. If your laptop has DDR2 memory, for example, only DDR2 RAM will work on it. After you add RAM, your computer will function more fluidly and run more applications simultaneously. You can upgrade RAM by replacing your old memory with a better module, adding a new one, or both.
Remove the battery from the laptop and unplug it from any power source. This prevents you from damaging the laptop or yourself during the operation.
Close your laptop's lid and flip the laptop over so the bottom is facing up.
Remove the screws on the small panel in the middle. You will find this panel either near one of the corners or in the upper-middle section, where you find the hinge of the lid.
Pry the panel carefully open with a flathead screwdriver and use your fingers to lift the rest of it off when you start to see the interior of the laptop through the panel.
Remove the new memory from its packaging, holding it by the corners to make sure you don't mess up the circuitry with grease from your fingertips.
Lay the memory stick at a 30 degree angle from the bottom of the laptop's motherboard, pushing it slowly into the memory slot.
Place the panel back on the laptop's bottom and screw it tightly. Turn on your laptop to test the new memory.
Always handle circuitry with the utmost care. If you want to use your bare hands, grab everything with your fingertips at the edges and do not smudge your fingers against any circuits. If you treat your circuitry right, it will last a long time.
Some eMachines laptops might not give you the ability to upgrade their memory. Do not try to tamper with the interior of the laptop if you do not see a memory panel. If you want to upgrade your memory, speak to a professional first.
