Laptop AC Adapter: Fix it or Throw it

Usually, we found that the little AC Adapter Toshiba can easily come undone, leaving your computer to run out of battery. As my HP 391173-001 AC Adapter, I have ruined two. 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 can't turn on, it is most likely one of two issues: the power cable or the battery.

If you want to fix the AC adapter yourself, the following may help you and save some money: notice all these should be done very carefully and gently. I used to destroy power supply connectors for the sake of carelessness.

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.

Check 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 AC adapter power outlet.

Check 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 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.

Take off the Battery–Power on the computer with the Laptop universal AC Adapter cable plugged in but with the battery removed. This will determine whether the battery is the cause of the problem.

After the computer is back together, your computer does not start, you have probably put the hard drive in backwards. Then correct this. However, someone can't get the laptop screw again, so they need to take it to the service center for help. I used to throw my broken switch mode power supply away and get a new one, for the service center asked for $40.?????????
