My first generation MacBook Air intermittently resets display resolution to low when waking it from standby mode. Works fine when booting from a restart, but not on waking. Resolution is normally set to 1280 x 800.  Will intermittently reset to 800 x 600.  Is there a cmos battery that may need to be replaced, or some other possibility? Already reinstalled the OS. Running OS X 10.6.8

MacBook Air, Mac OS X (10.6.8)
