Hi andrew, Thanks for your response. I checked the Power management. Its has similar way (tick on allow the computer to turn off…...) Let me describe the problem with more details. there are two situations. Situation 1 While in working with Internet, if the direct power is disconnected (unplug the power cable) then the Internet also disconnect. It means, I cannot use internet only with battery power. Situation 2 If the computer switch on after shutting down, we cannot access to the internet until the Kaspersky data base is updated. Also, Kaspersky doesn’t update if the laptop is unplugged to the direct power. Hope you understand these situations and would like to have a positive feedback. Cheers,
