Power jack repair in Toshiba Satellite L305 L355

posted in: 8. Toshiba | 657

Today I explain how to repair damaged power connector also known as power jack in Toshiba Satellite L305 and L355 laptops. I started covering this problem in one of the previous posts.

Also this modification should work for the following models: Toshiba Satellite L300, L305D, L355D, P305, P305D, Pro L300, L350 and more.

I have a list of compatible models (reported by users) at the end of this post.

PROBLEM DESCRIPTION. The power jack gets pushed into the case and gets loose.

I will replace the original plastic jack with a generic metal jack purchased at RadioShack for about $3.
The RadioShack part number is 274-1576. This jack is designed for tip size 5.5mm O.D.x2.5mm I.D. You can order this jack online or pick it up in a local store.


Prepare Dell Latitude D500 for power jack repair

posted in: 4. Dell | 9

In a Dell Latitude D500 laptop the power jack is soldered to the motherboard. If the laptop loses power intermittently when you wiggle the power plug, most likely the power jack is damaged and has to be repaired. In order to repair the power jack you’ll have to remove the motherboard.

In one of the previous posts I explained how to remove the motherboard from a Dell Latitude D500 but it came out mounted to a metal bracket. You cannot access and repair the power jack while the motherboard is mounted to the metal bracket, it has to be removed first.

OK, let’s prepare the motherboard for the power jack repair.

In this guide I explain how to disassemble a Dell Latitude D500 laptop.

Also, you’ll see how to access and replace all other internal parts.

I had two different problems with the computer.
1. The power jack was damaged. I could have just resoldered the jack but the second problem was more serious.
2. The motherboard couldn’t charge a known good battery. Apparently it had a problem with the battery charging circuit.

So I decided to replace the motherboard.
