MacBook Core Duo: Coffee and cream on keyboard - black screen and beep

Thu, 07 Apr 2011 11:48:58 -0700

Child spilled coffee (with cream) on my keyboard but I was able to dab it up fast and felt like I cleaned it adequately. Several hours later opened lid to have grayed box saying "power down", I did. Now when I try to power up it just beeps; beep-pause-beep-pause-beep... continuously, NOT three beeps.

I disassembled to see if any liquid was inside and nothing there - dry and clean.

Was hoping the de/reassembling would "jiggle" problem gone but still get beeps and black display.

Ideas on what went wrong (other than hurting it's feelings by not pampering it after the spill...)

iMac Intel 21.5" EMC 2428: iMac i5, 3 on 3 beeps, black screen

Tue, 05 Feb 2013 07:24:29 -0700

First of all, sorry for my bad English.

I bought my iMac in July 2011, Intel i5, 21.5 ", 2.5GHz, 8GB RAM, 500GB HD, HD 6750M and since November 2012 he stopped working. When trying to turn it back on 3 beeps sounded and did not turn on more.

After a few days, I turned it on normally, it was OK. On another day, the problem came back: while I was using it stopped working and did not turned on, just sounds of 3 on 3 beeps.

The screen does not turn on, goes black and no other sound is emitted beyond the beeps.

I've done testing of the RAMs, but nor replacing them it works.

Has anyone had this problem and managed to solve?
