Re: It will not turn on
I believe the power button connection is part of the palmrest assembly on this model. If by "inadvertyanty disconnected" you mean "broken the connnectors" then I don't know what to say, otherwise you simply reconnect them. The service manual can be downloaded here. Any reason why you thought there was a problem with the power button connection?

The green light just show that the motherboard is getting power.
The power button of the front of the case is connected to the mother board, not to the power supply, usually in the extreme lower left corner along with the with the HDD and Reset Button cords; Power button wire are labeled and usually red/black.
If all wired correctly, possible bad or stuck power button or reset button.
Hope this helps.

The most common reasons for this are:
1. Switch failure (the button is broken)
2. Power Supply not working
If you can go inside the case of your PC (if confident that you won't mess up with any other thing).
First of all remove all power cords (even the monitor's wire)
open up your case again if confident but its better if you get it checked by a technician.
By the way to check the switch the method is given below (i expect that you have a reset button)
There must be a wire on which PWR would be written it will be directly connected to the mother board. To get to it look for the button inside the case and follow the wire, when you find the wire carefully take it out and carefully search for the wire of the reset button and connect the reset wire in the place where the power wire was connected.
Plug in all the wires back again cautiously and then press the reset button and check whether now it turns on or not.
If the above method works it means you have a faulty power button and if not then you have either a power supply problem or
In some extreme cases the mother board can be burnt.
Hello there: The first thing i would check is the power supply if this is not working it needs to be replaced Also you can unplug the power from the computer and open the case and find the power supply cord that connects to the mother board and dissconnect ti from the mother board , now press in on the computer power button and hold for 30 seconds and do the same for the reset button if it has one this will release any (ESD that may have built up ) now just reconnect the motherboard cord that you dissconnected earlier and plug in the power cord to the computer and try to restart OK? I hope that this has been very helpful for you Best regards Michael
check conections, did you isolated bolts while you ware inserting mother board? check condensators on mother board if there are some leeks... if this is the case ,,, buy a new mother board? is mother board new?
Perform power drain and check it..
This might be the issue with static charges on the Mother board.
If this is the case, follow the steps and the issue will be resolved.
1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter and do NOT connect the battery now.
5. Turn on the Notebook power.
Method 2: remove and reseat the RAM modules and check.
Method 3: remove the Battery which is on the mother board and restart the computer and check.
If the issue is still there, then connect the computer to any external desktop monitor and check. I hope the issue is related to the monitor or the Video card. In this case, please contact the nearest service center.
lay down the screen flat
then get the two screws under the power bar
lift up power button bar carfully,you will see ribbon cable connected to the mother board with little brown clips, one on the power button also, this ribbon cable is very thin, and you probably will see the cracks with maginfy, order ribbon cable on ebay
try to remove the motherboard from the casing and see it if the have
some capacitors or any circuit distroy. use other mother board for
testing chek your hardware one by one maybe some of your hardware
We have to open the system unit where the motherboard is located, but first pull off the power of your computer so that there will be no ground.
Removed the cover, before touching any part inside the system unit (motherboard) touch first the casing or chas-is of the system unit to removed the static in our body.
Let us first remove the reset wire usually the color is red and black it has a name reset at the connection pin at the mother board usually found at the bottom of the mother board, or follow the reset botton wire found infront of your system unit.
After you have removed, try to plug the power of your computer and turn it on. We can open our computer if the reset connection is off.
That will be the first step to know the cause of the problem. Try also to clean the motherboard using vacuum cleaner the portable only or clean paint brush, cause some of those problem due to dust.
