Ragarding my Thinkpad T510 laptop. Windows 10 (64-bit) installed with 8gb. However, it will only allow 2.93gig RAM to be used. Have tried all mannaer of attempts to cure. When I uncheck "maximum memory" on "Boot advanced options" it defaults back to "0" maximum memory after re-boot and will not save as 8096mb RAM. Have tried other fixes via command prompt, but all to no avail. Anyone any ideas how I can get my 5.07gig RAm back in use????

Many thanks for the reply. I have Intel(R) HD Graphics, although I have just noticed "Pen and Touch - Touch support with 2 Touch Points" which I confess means absolutely nothing to me!

Could you provide a CPUz screenshot of the other 4GB stick?
How long have you been on windows 10?
How long have both 4GB sticks been in your machine?
You seem to indicate both 4GB sticks in your machine a while, and recently the amount of usable ram has gone below 4GB.
Also go into task manager, performance tab, memory and provide a screenshot.
What is your full model number, ie 4349-2PU? A 4349-2PU has I7-620m and Intel HD graphics. The Intel HD graphics would have to use some of your Ram.
Check device manager for the Intel HD graphics, properties, adapter and see how much ram is allocated. [Someone else can verify this is where to find the value. It might be a setting in the BIOS].
Have you used any 2GB sticks in your machine lately?
Use system properties to check virtual memory. Is it system managed or custom size?

Thank you for such a detailed reply Mr Sclexman. Almost too much for me to take in really :-)
I've only had the machine, a manufacture refurb, for a year. It's always had Windows 10 from when I purchased it. Original RAM sticks in which I have taken out and then reseated. Intel HD graphics on board. No 2GB sticks used at all. Virtual memory is currently system-managed. I did chane to manual but it made no difference.

Make sure you have the latest BIOS. Boot into BIOS and hit F9 to load defaults.

Before you do anything serious, I suggest you back up all your personal files. Read this, which talks about SFC and DISM (if SFC alone doesn't help)
