The power button won't work. It will not turn it on or off. For a while, I was using the button that will take it in and out of sleep mode (when you open and close the laptop button), but I lost power the other day and now it has actually turned off - not just gone to sleep. Is this something I can service myself or is there a solution at all?
Problem was a loose connector. Unit would power up on port replicator, but power button did not function. Fix worked perfectly. Popped cover off just like video showed. Found loose connector. Two minute fix.

Re: Power Button Not Working
You may be able to remove the top panel that the power button is on. trace the wires to make sure there securely plugged in. (do be careful when removing that cover as you can damage the internal components if you are rough with it)

Gary, Could be power supply failure. Links below for trouble shooting your problem. "I hope this helped you out, if so let me know by pressing the helpful button. Check out some of my other posts if you need more tips and info."
I doubt there is battery problem, have you tried switching on laptop without battery and connecting through the laptop charger? most probable your battery is not taking the charge. so suggest you to disconnect the battery and try using laptop with charger then you'll find the problem.
First try using a different ac adapter/power cord.If after trying that it won't power up it only leaves the power board where the power button is located may be bad or the power jack where the ac adapter/power cord plugs into the laptop may be bad.Alot of the time when the ac adapter/power cord gets weak or stops working at all will cause it to not charge or not turn on even plugged in.
Im very sorry to hear that, please follow these simple steps for you to be able to isolate the exact problem.
1. Removed the battery.
2. Connect the laptop directly to the power outlet without using the battery just for the meantime.
3. Turn on the laptop. If the laptop is able to power on, that means that the AC adapter is working fine as well as the DC port. If the laptop is not able to turn on, it maybe the AC adapter itself or the DC port.
4. Try to use another AC adapter if possible, make sure that that AC adapter is working fine. If the laptop is still not turning on, the problem is with the DC port itself. In that case, you will need to replaced the Motherboard itself.
Hope this will help...Thank you for using Fixya...
Try this to see if can give us some codes with it's on board diagnostics. Hold down the function button of your laptop and then the power button while still holding down the Fn/Function button on the left side of the keyboard. See if this gives you either an error message on your screen or, flashing lights above your keyboard. Pay attention, write down what lights where lit up what ones flashed, etc. This is to diagnose if the LCD isn't working. Comment back if you get either the light code or the error code on the screen. IF nothing happens try holding the Fn/Function button on the left side of keyboard and holding the F4 button, see if that makes any lights flash above your keyboard.
Believe it or not, the number one reason why a computer won't turn on
is because it wasn't turned on! Before starting a sometimes time consuming
troubleshooting process, make sure you've turned on every
and power button on your computer:
Power button/switch on the front of the computer
Power switch on the
back of the computer
Power switch on the power strip, surge protector, or
UPS (if you have one)
Perform a "lamp test" to verify power is being provided from the wall. Your
computer isn't going to turn on if it's not getting power so you need to make
sure that the power source is working properly. Note: If you have a multimeter or another electrical testing device
you are welcome to use that to test your wall outlet (and power strip, surge
protector, etc.). The lamp test is useful if you don't have an electrical
power supply. At this point in your troubleshooting, it's
very likely that the power supply
unit in your computer is no longer working and should be replaced. You
should however test it just to be sure. There's no reason to replace a working
piece of hardware when testing it is fairly easy. Replace your power
supply if it fails your testing. Important: In the huge majority of cases when a computer isn't
receiving power, a nonworking power supply is to blame. I bring this up again to
help stress that this troubleshooting step should not be skipped. The next few
causes to consider aren't very common.
Test the power button on the front of your computer's case. It's not a very
common point of failure but your computer might not be receiving power because
the power button on the front of your PC is damaged and is not actually turning
your computer on.
Replace the power button if it fails your testing.
If you're confident that your wall power, power supply, and power
button are working, it's likely that there is a problem with your PC's
motherboard and it should be replaced.
