My Inspiron 1100 was having a few issues so i reformatted it with WinXP.  I have all the drivers in and it is running perfectly.  THe problem is when I close the laptop and open it back up the computer does not repsond.   I have to power off then on to get it working again.  How do i fix this?  I told it to never hibernate/turn off hard disk/turn off monitor and this didnt fix it.
