Windows 10: Why does task manager show 50% ram available out of 16GB

I have an HP Pavillion laptop with an I5 1135G7 Memory It says 7.7 GB in Use 8 gigs available. Under GPU it says .6 of 7.9 GB shared memory. My question is, is the shared memory for the GPU the reason taskman tells me i only have half my RAM available. For clarity see Pictures.

Task manager showing less ram than available

My laptop is a Huawei Matebook D15 and it has 16GB ram.

when i open task manager it says Im using 20% (400mb) of ram!??!

available ram is 15.8GB

 

RAM=16GB,USED RAM=2GB,RAM USAGE 50%?

I hope you can understand my problem from the title, but let me explain a bit further.

I'm no genius when it comes to computers, but this feels weird.

Yes, i've tried to search a solution, but what seems most reasonable is a hardware problem so before i take it to an expert i'd like to ask here about my problem.

I'm using (right now) around 3gb of my ram, but my ram is 16gb (usable 15,83 or something like that) and Task Manager says that 50% is used. What?

Why is Task Manager is showing lesser RAM than installed?

I was surprised to open Task Manager on my PC, as the RAM it was showing was 8GB, because actual RAM I installed was 16GB. I instantly opened up my cabinet and put both my 8GB RAMs into different slots. Rebooted and opened up dxdiag to confirm I had 16GB RAM.

But Task Manager still showed 8GB RAM.





On the other hand, the UEFI says I have only 8GB RAM available. Here are my motherboard details:

I've read this post: RAM usage % on Task Manager lower than actual RAM but I don't find anything relevant. Earlier, Task Manager used to show full 16GB RAM inside the left column.
