I've had a lot of problems with hibernation causing errors and not working properly. I've also read many posts here from others who also have problems as well. My suggestion would be to not use the hibernation mode at all. Use standby, manually turn off the monitor and see if that works.
This might be an application or hardware problem, but I'll post it here.
I just bought a TV tuner card (NEC SmartVision HG2/R) that includes software for recording and timer record. It has an option to automatically "wake up" from hibernation/standby just before it records a programmed record. I've followed the instructions for this, but my system won't automatically wake up from either hibernation or standby. I have hibernation enabled and I can put the computer in and out of hibernation mode manually without any problems.
The card also included a separate application that has an "auto wake" feature for downloading the program guide automatically while you're away. This one doesn't work either.
I'm pretty stumped. I don't understand how the PC is supposed to know when to wake up. It's not possible, is it? The troubleshooting guide said that there might be a bios option that I can change to fix this, but my bios doesn't have any options related to hibernation or standby mode.
Don't tell me I have to change something in the power options control panel. There aren't very many options in there and I've messed with every one of them. If anyone has any good ideas, please help.
