Why won´t my Dell™ PowerEdge server resume from hibernation while using the Microsoft® Windows® Server 2003 operating system? - Technical Tip - 131690

Disable hibernation in the operating system.
 

The operating system is behaving normally.
If the OS was to resume without regards to memory, it would be violating measures for data corruption and good housekeeping.  Avoid using hibernation when the maxmem switch is being used or vice versa.

To disable or turn hibernation off, perform the following steps:

1. Click the Start button.
   
   NOTE: If the Start Menu is in Normal View, click the Control Panel icon.  Otherwise, if the Start Menu is in Classic View, continue with the steps below.
    
2. Point to Settings and then Control Panel.
3. Click Power Options.
   The Power Options Properties window appears.
4. Click the Hibernate tab.
5. Click the box next to Enable Hibernation, to ensure there is no checkmark in the box.
6. Click OK.

Hibernation fails when the maxmem switch is added to the boot.ini file.
 

When the Microsoft® Windows® Server™ 2003 operating system goes into hibernation, it takes a snapshot of the memory.  If there are memory changes when the system is coming out of hibernation, hibernation will fail.  This problem can be associated with the maxmem switch that some customers put into the system''s boot.ini file (usually to run applications that do not run in systems with more than a predetermined amount of memory).  The maxmem parameter switch can limit the amount of memory that the operating system can actually see and cause any resume from hibernation to fail.
