I just had to reinstall my XP in my Dell Inspiron 4100 notebook and now I am having problems with standby mode. Before the new install I could shut the notebook and the computer would go into stanby mode and after opening the notebook it would resume right where it left off. Now it will still go into standby but when i open the notebook it takes forever and is really slow. Like I said it never did it until the new install. Any idea's what it could be?
