How to add or replace RAM memory in an HP ProoBook laptop 

The process is simple, especially when it comes to the series of HP laptops that we used in the video.
In the video, we used an HP ProBook 6570b laptop, where the cover to access the motherboard is very easy to remove.
After removing the cover, we immediately accessed the slots for RAM memory, we showed one board that was already in the laptop, and then we added another RAM memory to the second, remaining, slot.
After that, we turned on the laptop and checked whether we see more RAM memory in the software.
