Hi,
If I leave my si 1520 on for several hours (like overnight) it goes into some strange standby mode, which is impossible to wake up without reseting the computer. The computer seems to be on, but the screen is off and the only way to get the laptop to react is to hold down the power button until it shuts down.
In the energy settings, everything is set to "Never" except shutting down of the screen after 30 minutes idle time. There is no problem waking up the computer with the screen shut off after a few hours, the problem only seems to arise after many hours of idle time and is thus very difficult to troubleshoot.
Any ideas?
Thanks,
Erik
