Re: Lenovo USB 3 Port Broken socket - compatible types?

If you have the damaged one why not compare its dimensions with ones that are available.The pin connections are the same on all US sockets. Parts suppliers always put a pdf file available giving dimensions.

Thank You,I will try today as you stated.The laptop works fine on battery.One thing I didn't mention in my first post was that the battery charges as normal.The fault seems to be when the DC input supplies the laptop with or without a battery.

In the last 15 years ,better coatings have been found( higher voltage breakdown,more flexible when being wound). The colour has changed with it to a lighter brown.To anybody who does not repair electronics much,can be confused
