Hello, My name is Tim and I will assist you in finding an answer to your question.
JACUSTOMER-e4ejmk0b- : I have to do this on my phone because my computer won't turn on.
Remove the battery and the power adapter and press the power button down for about 45 seconds and then release it. Then plug just the power adapter in and press the power button to see if it comes on
JACUSTOMER-e4ejmk0b- : It's not a laptop, it's a desktop. Where is the battery?
It didn't work.
Sorry I thought it was a laptop
Can you remove the side of the case to reveal the motherboard and see if it has a lit LED?
JACUSTOMER-e4ejmk0b- : If it helps, another time this happened I pressed the power button and it didn't turn on for a full four minutes. I don't know what happened there, but that was the start of it being weird. Now it won't turn on at all.
Are you sure it is not in the hibernate mode
JACUSTOMER-e4ejmk0b- : A green light blinks where the ethernet cable is in, so it seems like power is being supplied to the unit.
It is not in hibernate mode. But what was also interesting is that I would put it in hibernate mode before going to bed and it would always boot up on its own around 5 AM every day.
Unplug the power cord and press the power button in for about 45 seconds and release it. Then plug the power cord back in and see if it will turn on
I tried that. It didn't work.
OK unplug your video card off the motherboard and try turning it on again
JACUSTOMER-e4ejmk0b- : Okay I took out the video card, but it's still won't turn on.
Ok is your power supply a switching power supply? If so check the back of it where the little switch is and make sure it is set to 115V instead of 230V
JACUSTOMER-e4ejmk0b- : It is not a switch, just a standard PC power supply.
Does it have an on/off switch on the back of it
JACUSTOMER-e4ejmk0b- : No
It should have a voltage selector on the back of it that is small and red that slides to the left or right to switch voltages
JACUSTOMER-e4ejmk0b- : Wait I think there might be a switch it's covered with tape but it says 115
ok just needed to make sure it is set to 115v. Put the video card back in and remove the heatsink and fan and the processor press the power button to see if the computer will power up
JACUSTOMER-e4ejmk0b- : I'm sorry I don't know what the heatsink is.
It covers the processor to keep it from getting too hot
JACUSTOMER-e4ejmk0b- : Okay this might take a while though.
JACUSTOMER-e4ejmk0b- : Should I have the power supply removed while I am doing this?
just make sure the power cord is unplugged from it.
Also make sure you do not bend any pins on the processor when removing it from the slot
JACUSTOMER-e4ejmk0b- : I removed the fan from the processor and press the power button nothing happened
Did you remove the processor also?
Do you see a lit LED on the motherboard?
JACUSTOMER-e4ejmk0b- : Isn't the processor everything? I don't know where to start.
There is no LED on the motherboard. But as I said the ethernet plug in blinks green when the power cord is plugged in.
The processor is the brains of the computer but I need to make sure that it is not causing the power board not to come on
Can you remove it easily
JACUSTOMER-e4ejmk0b- : I can't remove it easily, no.
OK do not worry about it
Put the fan and heatsink back on and plug the power cord back in
While looking at the motherboard make sure the little cables for the front panel are plugged in good
JACUSTOMER-e4ejmk0b- : Everything seems to be plugged in well.
I should mention that it was working fine two days ago. I shut it off before I went to work and when I came back home, it wouldn't turn back on.
Ok try turning it on again but this time hold the power button in
JACUSTOMER-e4ejmk0b- : It's not something I push in really more just a little trigger on the top. But I tried holding it down for about 45 seconds with the power cord plugged in and out and neither worked.
Are you sure that the on'off switch didn't go bad
JACUSTOMER-e4ejmk0b- : I'm pretty sure it just didn't go bad. I would often bump the switch accidentally with my foot and the computer would shut off.
Just have to check
JACUSTOMER-e4ejmk0b- : What is the easiest way to check?
The only way to check is to shoot the pins that the power switch connect to but I do not know if it is safe or not
Let's bypass that
I think the best thing to do even though the NIC light is flashing is to swap out the power supply to see if the computer will turn on. If it does then you know the power supply is bad. If it still doesn't then your motherboard needs to be replaced
JACUSTOMER-e4ejmk0b- : I've tried different outlets and it doesn't work.
You need to try a different power supply because I believe either the power supply is faulty or the motherboard is bad.
