Sony VGN-FW390J Ram
RAM is a type of volatile memory as its storage is removed every time you turn your laptop off. Having the RAM installed is mandatory even for the Sony VGN-FW390J to boot up. The clock speed of the RAM is predetermined through the specs of the motherboard, and the minimum storage size is governed by the operating system. Because RAM is only temporary storage for the processor, it does not have the ability to store files such as text documents or movies. But, it has a positive impact on the speed of your Sony VGN-FW390J. Your laptop RAM stores pieces of information that the processor uses for executing commands. If you need to buy more RAM and are unsure, just know that it is impossible to have too much RAM!
Major clues your laptop RAM is in dire straights
- You get a lot of random reboots on your laptop as you use it
- The laptop screen does not light up when booting up
- The system cannot report the correct amount of RAM as it should
- Silence when trying to power on your system
