HP laptop sleep after few minutes

0

I'm using HP Probook G2 laptop. I don't know why my laptop goes to sleep after few minutes. It doesn't go to sleep after specific time, sometimes it takes long but sometimes short period. I have set "Never" sleep and "Never" turn off display in Power Options. Is there anyone who experienced this issue before?

Kaspersky has been installed on my laptop, is it a cause? Or maybe some other program?

Did your laptop come with any preinstalled governing power management software? – root – 2015-02-02T13:08:18.250

Is it connected to power or on battery ? Note that on-battery power rules are different from the ones applied when the notebook is not on battery. If you changed the settings, make sure you changed them for both cases.

Try taking a look into the registry at [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\User\PowerSchemes\ to see if anything is wrong there. For "never" ACSettingIndex should be dword:00000000 . Alternately, just imput into a command prompt "powercfg -change -standby-timeout-ac" and thatll make sure everything is set. – Overmind – 2015-02-02T09:43:23.747
