I have been given an Advent QC7003 Desktop[Quad Core Intel CPU 8GB DDr2 Memory which was installed with Windows Vista 64Bit Home Premium.I have removed Vista and Installedl Linux Fedora 25 64bit LXDE.I have since had a problem with the PC going to Sleep,even though I have deactivated the SCREENSAVER?The PC will not wake with Keyboard or Mouse,and I have to restart the PC.Additionally there is no Reset Button on this PC,how do I use this Power Button to Restart the PC without switching it Off?
Any help comments appreciated..MichaelThere is a SOLUTION here for Fedora 17, it might still apply to 25.
