A friend of mine shut down his office computers yesterday only to arrive this morning to discover that 3 out of 5 Apple desktop computers refuse to boot. The sockets (power outlet) was also turned off, and no other person had access to the office.
We have checked the sockets and the cables, and they are ok but the computers refuse to boot.
Please can somebody please help as we are not professionals in this area.Â
Apple desktop computer refuse to boot
Â
Hello friend,
Â
Whatever you told about your problem is not a dangerous one and you don’t have to  worry about it because this is not a fault of any computer or a socket but  is a problem of electricity. I want to say that sometimes there are little shocks or jerks that come in the power supply and that causes a hindrance in operating the systems and also it causes automatically turning off the computers.
Â
So your solution is that you must  check your voltage level and also the electricity supply connections whether they are ok or not. May be there are some  loose  wires.  So do check those as well.
Â
Cheers.

You are still lucky you have two more left that are still working. Check first the entire AC outlet that those computers are using if it has power. If the whole line is ok then the problem is only with the computers. These things usually happen to computers. Sometimes you use them with care but the next day it would not boot. You maintain its system and defrag it regularly so the data access will be smooth. But you did not know that after only two days the whole Windows platform crashed without having a clue.
We really can not predict the life of an electronic device. You expect it to be using for about 10 years and yet on the second year it went down.
With the status of your computers, if the unit really doesn’t respond when you are pressing the power button, check if the power cable attached to the CPU is securely connected. If the cable is ok, then the problem would be its power supply. Bring the CPU to a certified technician to fix it. But, if the CPU still powers up but can not boot to Windows, a simple hard drive format and installation of operating system is needed.
