This switch off randomly happens at-least 3-4 times a day. I used the "catlog" app to see if any errors or failures are logged (which may cause the shutdown), but the log entries are so many and so many are generated that they just fly past for me to figure out anything. Is there any specific error that I may have to search for? Any ideas on how to approach the problem and maybe solve it? If it turns out to be a h/w issue, I can send it for service. But I need to ensure that itís a h/w issue Any help will be greatly appreciated. Thanks!
