Make sure you have nothing plugged into the USB ports or a DVD/CD in the player.
1. Remove all connections to the laptop. (USB, power, etc.)
2. Remove the battery.
3. Press and hold the power on button for 1 full minute.
-> Explainer. Yes, many machines only require 10 or 15 seconds but this reset instruction is generic and I've found people hold the button for 9 or 14 seconds so let's write the full minute.
4. Let go of the power on button.
5. Slip in the battery pack.
6. Plug in the power to the laptop and to the wall.
7. Do not plug in any other devices.
Try the power on button!
If that does not work try it again without putting the battery back in. If either of these works, it is an indication that you have a bad battery. Do not use it with the bad battery install.
If that does not work check the lights to see if any of them are blinking in a pattern. Sometimes you can get a diagnostic from a blinking caps lock or some other light.
Check the power jack in the puter and see if it is loose. They have a bad habit of becoming detached from the motherboard.
If no lights blinking or other wise you might have a dead AC adapter. Find someone with a DVM and see if you can check it. If you have no experience with DVM get someone with experience to do it. You can cause damage if you do it wrong.
TWB 35+ years of experience in the service industry. You name it, I have probably fixed it. I did not design it, I did not build it, I did not break it, but I am the one who can fix it. What that means is that I have spent a life time taking these things apart and seeing how they are made. I have seen every dirty trick used by low end manufactures to bait people into thinking they are getting a good deal.
The difficult we do right away, the impossible just takes a little longer.
I hear voices, so please be quite so I can listen to them.
