I upgraded my HP 2000 laptop from 4Gb ram to 8Gb. Updated the BIOS. bios sees 8Gb. installed a minimal (drivers only) win7 and it sees 3.6Gb installed ram. Swapped position of ram sodimms. Reinstalled, same problem. Updated all drivers. Used msconfig to see min ram to 8192. Upgrading to Windows 8 is not an option. Linux may be an option of someone can recommend a distro that will work well with this machine. It fast, but I would like to use all the ram since I just paid for it. Just tried intsalling openSuse and it only sees 3.5Gb as well.
