Acer Aspire 5720 AC adapter power supply Troubleshooting

Laptops come with an adapter that plugs in and attaches itself to a little metal electricity conductor inside the computer. These little Acer Aspire 5720 AC Adapter power jacks can easily come undone, leaving your computer to run out of battery. To have this repaired by a professional, it can cost you upwards of one hundred dollars just to have them look at it.If your laptop isn't turning on, it is most likely one of two issues: the power cable or the battery. It is important to attempt to isolate an issue prior to calling customer service, as you will either be able to fix it yourself, or will be able to provide more useful information to the technical support agent.
If you want to fix the Acer Aspire 5720 AC adapter yourself, the following may help you:
Flip your laptop over and remove all of the screws. Be sure to unscrew the ones holding the screen in place. Some screws are different sizes, so keep them sorted in order of where they were removed. Uncover the hard drive housing located at the bottom front of your laptop. The hard drive will be screwed in, so you have to remove those screws before you can take out the hard drive.
Test Electrical Outlet
Plug a different device into the electrical outlet you are using. Occasionally, the issue is not with the laptop at all, but rather a bad Acer Aspire 5720 AC adapter power outlet.
Inspect the Power Cable
Inspect the power cord using vision and touch. Check for any nicks or gashes in the cord, and feel for any possible issues such as a break in the wire inside.
Check Power Cable Connection
Verify that the Acer Aspire 5720 AC adapter power cable is properly plugged into the outlet, the laptop and the transformer box in the middle of the cable, if there is one.
Remove the Battery
Power on the computer with the Acer Aspire 5720 AC adapter power cable plugged in but with the battery removed. This will determine if the battery is the cause of the problem.
Reassemble the computer by putting everything back in the position you unscrewed it from. If, after the computer is back together, your computer does not start, you have probably put the hard drive in backwards.
