USB on laptop is damage an I wan to know what can I do to fix it or do some sort of DIY thing to the laptop to make use of the USB?

Go to dell's web site and get the latest drivers for your laptop. If that doesn't help, you may need to test to see if the +5 volt rail of the USB ports are working, (do lights on the USB device light up at all? ).

Some laptops save power by turning off the ability to power things through USB. You can test for this by using something that does not get it's power from the USB port by default. Any battery operated device that uses USB should work.

Or an external HDD/DVD/CD drive that comes with a wall adapter. If it turns out that no lights come on or devices that have their own power work proper then it's up to you to figure out how to turn that off for your lap top. Start with reading the manual.

If all of the above does not work then it is likely that the USB controller of the laptop is(burned/fried/dead/ruined/cooked/broken) and will never again work.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
