Although RAM is only temporary storage, it plays a main role in PCs. It boosts performance by permitting the system to rapidly store and get back data. PCs are intended to utilize "virtual" memory when low on real memory, but it is a slow, useless process. Thus, the more real memory you have, the better. Adding RAM to a Compaq Presario is a simple upgrade that will inhale life into an aging system.

Instructions

1. Step 1

Decide if there are any accessible slots to add RAM. If there are no slots accessible, upgrade the RAM by changing it with memory that's quicker and/or higher capacity. Even then, motherboards are restricted by type, speed and size of memory it can hold. If Compaq is already at its maximum, the memory can't be upgraded.

2. Step 2

Put laptop on a solid, hard surface. Take out battery. Detach the power supply from laptop and unplug it from wall. Detach other peripherals, like mouse and flash drive.

3. Step 3

Dishearten the power button to release electrical buildup that could harm laptop. Flip the Compaq Presario over and find screws protecting RAM. There must be two. Using screwdriver, take out screws and place them in a safe place. Use screwdriver to pry the cover off, and then set it to the side.

4. Step 4

Remove the old memory by softly snooping open two metal prongs. The memory will snap upward; take it on side edges only. Be alert not to touch the gold strip. This area should remain clean for appropriate contact with laptop.

5. Step 5

Line up the latest stick of memory so that notches match the prongs. Holding it at a 30-degree angle, slide it in and push down until a snap is heard. Change the cover, protecting with screws. Flip the Compaq right side up, connect it into wall and power on. If it powers up effectively, again install battery and peripherals. If it does not, reseat the memory and try again.
