A new laptop functioning well in almost every way. The volume hotkeys do not work properly. The volume icon in the system tray can be used without any problems. However the Lenovo on-screen volume visual that coincides with the manual hot keys is whacko. It pops up every 1-10 seconds. If I try to press the actual manual hot key +, it will slam all the way up to 20, then back to zero. The mute button mutes, then immediately unmutes.
