On Win2K, it's under Control Panel -> Power Options -> Hibernate -> Enable Hibernate Support. You'll lose 1MB of space on C: for every 1MB of RAM in your machine for the hibernation file though. On a 256MB Celeron-700 laptop, that's not a big deal. On a desktop machine with 1GB of RAM, it's a slightly bigger deal. I've even got it enabled on the Linux installs - Matthias Hensler has been patching the Fedora Core kernels to enable Suspend2, which does the same as the Win2K hibernation subsystem, but it does it slightly faster :) What's really neat is hibernating Windows then rebooting into Linux and having it come back right where I left it before I hibernated Linux. Very neat, and very handy on a laptop - especially my power-guzzling Toshiba Satellite Pro 4600. I installed an Intel 2200BG (Centrino) wireless card in it - works quite nicely, except it knocks a good chunk off the battery lifetime. Shutting off the wireless gets me another 20 minutes of runtime in Normal mode. Also swapped the 10GB Travelstar for a 40GB Seagate Momentus 5400 ("because 10GB isn't really enough for 2K and FC4 dualbooting). So far the best runtime I've managed is two hours and 24 minutes. If anyone's done better, please share your secret with me - Toshiba say you can get three hours, but I bet that's with the hard drive spun down and the TFT off... I've also been meaning to play around with antishock protection for HDDs. One of these days I'll wire a laptop HDD up to a PIC and an ADI iMEMS accelerometer. "If sensor_detects_freefall() then set_drive_power(KILL_5V_FAST);" or something like that. According to Seagate's datasheets, the fastest way to spin down a laptop drive is to kill its power and make it use the back-EMF from the spindle motor to kick the head back onto the loading ramp. It's also listed as the most violent way to shut a drive down, and is "only recommended for emergency situations". Gee, I wonder why. I guess what you'd look for is an event where the sensor reported a G-force of less than 0.5G (i.e. freefall). You see that and you kill the HDD's power. There's an interesting appnote on freefall detection at (or ). -- Phil. philpem@dsl.pipex.com http://www.philpem.me.uk/ -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
