I need to plug it out and back in, sometimes   multiple times to get the expected performance. - Scrolling content and playing videos is jerky. - Keys that are reported as ACPI events do not work anymore, most noticably   the sleep key. Keys that bypass the OS (e.g. screen blank, touchpad and   camera on/off) still work. So do keys that are reported as keyboard events,   e.g. volume up/down.
