Sorry, but what happens if I don't use my Surface from Lunchtime but want an alarm to go off the next day at 9am?
The best option isn't sopping the computer from going into Hibernate or extending the time before it hibernates. The best solution is to interrupt the Hibernation when you need things to happen.
Unfortunately Task Scheduler won't do this (as the Task is unable to run as the PC is in a Shutdown state). The app I linked to above (and there are other ones out there as well) will be able to interrupt the Hibernate and allow the Alarms and Scheduled Tasks to run as normal. Best of all it can be turned on and off when you don't want it, without trying to remember messy hacks.
