#Mid 2011 imac review Pc

Since we're talking how this computer was used/stored in damp conditions…this may not be the exact same as suddenly the computer exposed to liquid (like a liquid spill that happens to laptops). It would seem that the chances that it's water damaged would seem minimal. Since this computer seems to work fine after removing & replacing the PRAM battery…and will even work fine if the computer is put to sleep & woken up. Could be one thing or multiple things…or something that's working today, may not work tomorrow. If this computer really is suffering from water damage…I'm sure you must know…water damage can be so hard to diagnose. When I remove the battery and replace again then plug the power cable in the back, it starts up by its self without pressing the power button, I thought maybe this was me resetting the system and bypassing the SMC chip.Ĭould the Area on the logic board in the images be the cause of the problem, I didn't think an overheating LCD would cause this sort of Temperature to melt solder, if someone could confirm this is how the board should look then it looks like a new logic board is required The area on the board that was mostly corroded was on and around the SMC chip and the Ram slots but this might not be the problem as this has now cleaned up well, the area that I took the images may be the issue and has always been the issue, but my knowledge of surface mounted components is very limited the area just doesn't look right the two components have a bridge of solder between them. Yes I know it sounds quite difficult to get an iMac water damaged, but this one was in a extremely damp bedroom, its not a spillage problem it was more moisture in the room that caused the corrosion on the logic board the Ram slot is missing so that was the area that the moisture was entering I have taken some pictures from an area on the board that looks suspect to me and I've replaced the power supply with a new one so that's ruled this out, the power button also checks out with the multimeter so no issues there, can someone explain why this wont turn on from the power buttonĪny you guys shed some light on the issue I cleaned the best I could but with still no joy, but I discovered that if I remove the Pram battery ( I call it the cmos battery) and reinstall it and plug the iMac into the main power the machine boots to its desktop and runs without any issues without touching the power button at the rear.

Hi I'm new to this forum and Mac's in particular, dare I say am a PC guy, I was asked to have a look at his mid 2011 iMac that was having issues, he was having problems with it starting from the power button then eventually it wouldn't start at all even with every reset known, when I opened it up I discovered there was water damage (corrosion) to the logic board especially around the smc chip.
