problem resuming windows vista after laptop being idle.
I bought a brand new Sony Vaio VGN-SR35G laptop just few months back. Initially had no problems with it. Always i'll put some downloads and leave my laptop idle during nights. For the past week, my laptop hangs if left idle. Now it has become too frequent, even if it's left for only about an hour. I have changed the settings to 'do nothing when lid is closed' and also i set the HardDisk to stay up. This should put my system UP for as long as i want to. But then even after these changes have been made, the problem still occurs. After i left it idle, and try to use it again the desktop actually seem to appear just fine (it doesn't appear as black,it actually appears just as it is) but when i try to access any application it'll start to hang. I can't even access the task manager, all I'm left to do is to manually shutdown the system. Could anyone please help me with this? I know this is probably a known issue,some would might respond by updating the graphics and so..but is that really the case?or is this an OS (Windows Vista) issue?
