This refurb system I really like. But I upgraded the ram to 4 gb and the system recognizes 4 gb. But, it says only 1 gb is "available." Why? Is there a way to improve the amount of ram available?
I love the keyboard on this little system, my granddaughter is using for homeschooling.
The rest is being used by Windows or hardware inside the system - that's normal; it means you have 25% of your memory available.
If the system has an integrated Intel GPU (likely, as most of the discrete nVidia ones are long dead due to a design fault by now), it's also using system memory for video purposes.
