Recently, without any obvious software changes, hibernate on my windows xp professional sp3 laptop, TOSHIBA M100, simply stopped working. You can click Hibernate, then it simply goes into the preparing to hibernate stage, but then switches back to whatever I was trying to hibernate from. No error message comes up, it simply goes back to whatever stage I was trying to hibernate from. Has anyone had a similar error and found an effective solution?1 person needs an answerI do too
