I have the SP 1st Gen. This is my second SP, after I returned the 1st one which was crushing all the time. The new one is working as expected, until it sleeps. Every time I let it sleep and then come back to work on it (say 2 hours later), I always have to log in and start from scratch because, alas, instead of sleeping the SP was actually off (I let the SP sleep in one of 3 ways (1) let it sit there on battery and it eventually sleeps, (2) close the Type Cover, (3) press the power button. I set my battery profile to hibernate after pressing power button or after a set number of minutes). No matter what method of sleeping, I find that all my programs have been closed, Word or Powerpoint have some "recovered" documents, etc. I have about 14GB free space at the moment and I'd assume that there is enough space to hibernate, but that apparently isn't happening. All my updates are current. Any ideas? Thanks in advance.
