You must run the Sleep Manager utility after installing additional
memory in order for the 0V Suspend function to operate in your
system.  If Sleep Manager is active, it will auto-adjust the
partition/file on your notebook for 0V Suspend to function properly.
If you are using an operating system other than Windows 95 or
DOS, you may need to re-partition your hard disk drive to allow for
the additional memory.  Check with your system administrator.
5. When you are done, replace and screw back the memory upgrade door.
