Im about to buy a very cheap (no function) core i5 2.5 iMac 21.5 (mid 2011). but the seller tell me that he start the computer and the screen remains black and three beeps sounds. My question is the next one: ALWAYS , when I heard the three beeps is the RAM, or coult it be anything else like Logic board. I found this:


1 tone, a 5-second pause, repeatNo RAM installed
3 successive tones, a 5-second pause, 3 successive tonesRAM does not pass data integrity check
1 long tone when holding down the power buttonFirmware upgrade in process. See About firmware updates for Intel-based Macs for more details.
3 long tones, 3 short tones, 3 long tonesFirmware restoration from CD in process. See About the Firmware Restoration CD (Intel-based Macs) for more details.



But I don't know if it is always like this. Im not sure to buy the iMac, I mean, if it is the RAM its OK, I will have a very cheap iMac with me! But if it is the logic board....well, that's not so cheap!


Thanks all!
