Lenovo IdeaPad Z40-75 Ram
RAM is actually volatile memory as the data it holds is deleted when you shut down your system. The RAM speed is predetermined through the specs of the motherboard, while the actual storage size is guided by the OS. Having the RAM installed is mandatory in order for your laptop to run. Because RAM is only temporary storage for the CPU, it does not have the ability to store files such as picture or movies. Instead, it has more to do with the speed of your laptop. Your laptop RAM stores random bits of information that the central processing unit uses for programs. If you are ever in doubt, remember that you can never have too much RAM.
Major indications of a barely functioning stick of RAM
- Silence when attempting to start your laptop
- The system does not report the right memory size
- You may get quite a few invalid access errors on your laptop intermittently
- The screen does not display correctly when you turn your system on
