Chosen Solution
Hi there I wonder if anyone can offer any advice. My friends’ computer stopped booting so he gave it to me. It’s a nice computer that I would like to repair and give to my mother. Pressing the power button gives no response at all. I removed the screen and noticed there were no LED indicators alight on the logic board, so assuming it was the PSU I ordered a replacement. I also ordered a PCIe Blade SSD as the logic board allowed it. I removed the existing HDD and returned it to my friend. After the new PSU arrived, I installed it with the new SSD and put it back together however the machine still has the same issue (along with no LED indicators). So I tested the DC voltage on the new PSU and it noticed it was giving me a zero reading (must be dodgy so I will return it). I then installed the old PSU and I am actually receiving an 11.80v reading on 3 pins. So my question is, in anyone else’s experience, do you think this is a dodgy PSU (at 11.80v) or would it seem like the logic board is the culprit? Any advice is greatly appreciated! Cheers Luke
PSU problems, period. Most bad PSU will still give you a green light on LED#1 and you are not getting that far. Even though you probably can get cheaper parts, I get mine from ifixit because they carry a lifetime warranty, and I only want to do the repair once as my time is more valuable to me than doing a repair all over because I got cheap part. iMac Intel 21.5" (Late 2012-2019) Power Supply iMac Intel 21.5" EMC 2544 Power Supply Replacement
