Going to sleep before flat battery

[u415967]

I have just changed the hard drive in my Macbook Pro (500 GB, 7200 rmp Seagate), and now when my battery goes flat the computer doesn't go to sleep before hand. It just stops dead and I have to do a complete boot up when I swap battery.

Does anyone know why? How can I fix it?

Thanks

Richard

You could use the SmartSleep Preference pane to set you computer to sleep without writing the contents of the RAM to the hard drive and then change it back to write the contents of the RAM to the HDD (as I suppose, that's what your MBP did before).

There are also Terminal commands for doing this, SmartSleep is just a GUI for doing so.

Did you made a clone of the old drive to the new one or just a new install of Mac OS X?

I made a clone of the old drive so it should be identical.

Solved it. There was a sleepimage cloned from the previous drive. Deleted this and all is good again
