Lenovo ThinkPad Edge E420 Ram
Due to the fact that RAM is temporary storage for the processor, it does not hold files like documents or pictures. Instead, it will affect the speed of your Lenovo ThinkPad Edge E420. The speed of the RAM is imposed within the specifications from the motherboard, and the minimum storage size is dictated by the OS. RAM is actually temporary storage as all the information held gets erased when you shut down your system. RAM stores random bits of data for the CPU to use for executing commands. Some RAM is mandatory even for your laptop to even boot. If you are ever in doubt, just know that more RAM is a lot better than less RAM!
Some warnings the RAM should need replacing
- The laptop screen does not light up when you start your laptop
- Silence when you initiate your system
- The OS does not display the right RAM size
- You tend to have invalid access errors on your laptop throughout the day
