Boot Failure 9 beeps
Hí,
Recently my iMac Late 2009, when booting you can hear 9 beeps (3 short, 3 long and 3 short), this url, the problem indicates that it has detected a corruption of the ROM EFI and the team is in recovery mode EFI ROM, but if I leave, the screen goes black.
So far everything seems normal, but this only happens when I turn off the computer, ie if I connect the device to the electric current on first boot the computer functions normally, if I turn it off and back on again, the team gets to the screen in black and I must disconnect the power cord, leaving about 5 seconds and plugging it back.
This procedure clears the NVRAM, so I'm not sure if the battery of the device is in poor condition or it may be something else.
I hope your opinions, thank you and happy holidays.

The technical service of apple, suggests to me that is due to the ram, but I should take it for service. I changed the ram by a new and still under the same conditions.
Is this a good question?
