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.

I had two different problems with the computer.

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.

How to open Dell battery

Take apart Dell laptop battery

Here’s how I was able to open the battery from my Dell. I had to take it apart because the locking mechanism was broken. I decided to fix it by using the locking mechanism from another similar dead Dell battery.
I wasn’t sure if I can open the battery because it looked sealed.

To my surprise, it wasn’t difficult but you have to be very careful. If something goes wrong you can (and most likely will) destroy the battery or will not be able to assemble it back together. Proceed on your own risk.

Your computer will work in dual channel mode (recommended) if you install two identical memory modules. In my case, I’m going to install two 1GB PC2-4200 modules.
