I was wondering if there is any way to set the bios alarm clock through windows, so that my computer will be on and ready for me before I wake up. I would prefer a way to do it in VB, but if C++ is needed that is good too. Thanks for any help

There's plenty of code around to do that on *nix boxes, but, alas, MS has yet to implement it.  They've talked a great deal about it:

Overall power management
http://www.microsoft.com/whdc/system/pnppwr/powermgmt/default.mspx

OnNow Device Power Management
http://www.microsoft.com/whdc/system/pnppwr/powermgmt/devicepm.mspx

but there are sufficient variations in BIOSes that lack of consistent behavior under MS OSes has kept MS from actually doing anything.

Rather than posting a handful of links, do a search on:

nvram bios wakeup

and you'll get them all.


Caution - there ARE variations in BIOSes.  Do your testing on a box you don't mind rebuilding.  It's highly unlikely any real damage will be done, but better safe than sorry.  

I suspect the worst that would happen is something like not re-calculating the CMOS checksum correctly, in which case, the BIOS will reset itself to factory defaults on startup, the most irritating effects of which are date change and hard drive reset to CHS addressing.  

For this case (reset to defaults), I make sure I don't miss anything by referring back to the printed screen dumps of EVERY CMOS setup screen that I made when I built the box (parallel printer on the first parallel port, then PrintScreen).
