I have a Dell Vostro 3450 laptop connected via HDMI to an external monitor. Windows 7 is configured to use only this external monitor, disabling and turning off the laptop screen. This setup works when I cold boot Windows 7, but when I resume the laptop from hibernation, the external monitor is deactivated and the laptop screen is turned on. The laptop has a Intel graphics adapter and a ATI Radeon dedicated adapter. Both drivers are updated. Does anyone knows how to solve this? Thanks! | |||

Um... I am not sure if you are going to like this solution but... I am assuming if you the lil' guy hooked up to an external monitor that you also have him plugged in yes? So... you could just tell it via control panel power management to Never Sleep when plugged in. Alternatively, you could maybe double check your chipset drivers, maybe even go so far as flashing your BIOS. I think before I'd even go near flashing the BIOS you might try entering the setup and start disabling some of the power management features there but... if you do, I suggest keeping a handy list of which one(s) you are trying so you can put stuff back in the event of negative results. | |||
