Computer: Dell XPS L401X
Where: 3119 Sheppard Ave. E. Toronto, ON M1T3J7
Problem: Short circuit on the button board going to motherboard.
Touchpad not working.
Caution: Always use proper grounding equipment like heel grounder and anti-static mat. If ESD protection is not available, then use a wrist band.
- Remove all screws from the bottom of laptop and store them is tagged and sorted container like an ice-cube tray.
- Use caution when replacing these screws, longer screw will go through the plastic on the other side and ruin your notebook.
- Always remove battery and power adapter, ensure no power source is used during opening and closing of the computer.
- As a precaution, use power adapter (no battery) when computer is put back together and before driving all screws in. This ensures nothing was missed and avoids need to re-open computer saving time and frustration.
- Don’t use a power gun as shown in the video. Power gun will damage your computer and requires a lot of control. Even lowest level of torque will drive screw right through.
- Don’t repeat the short circuit, once found, simply eliminate it. Repeating shorts can cause motherboard to take damage, potentially blowing a fuse – they are expensive to replace.
- Touchpad cable was loose, simply re-enforcing the connectors fixed it in our scenario. Your situation may be different.
