Sony VPCSA21GX Ram
Some RAM is mandatory in order for the Sony VPCSA21GX to run at all. RAM is a type of volatile memory as its storage is erased every time you turn your laptop off. Because RAM is only temporary storage for the CPU, it does not have the ability to store files such as text documents or movies. Instead, it will affect the speed of your Sony VPCSA21GX. The speed of the RAM is predetermined through the specifications from the motherboard, while the size is guided by the software. Your laptop RAM stores small bits of information that the central processing unit uses for executing commands. If you are ever in doubt, remember that bigger is always better!
Clues to watch for to know your RAM is failing
- The software cannot report the correct amount of RAM
- The laptop screen does not display anything when booting up
- You tend to have access errors on your laptop intermittently
- Nothing happens when attempting to power on your system
