The battery has never been replaced. I'll tray that along with other settings. Thanks for suggestion. Thought SupportAssist would have detected that. SupportAssist isn't that smart. Post back and let us know how it goes after you replace the battery, etc...
After restarting XPS 8910 often the keyboard fails, as in, I'm unable to enter user password. I've run SupportAssist, but it found no problems or upgrades. I've looked in WindowsLogs, but found no issues related to USB or hardware matters.
