Dell Inspiron 3521 Shorting fix Step by Step Part -1
Okay, let’s talk about fixing a “short” on a Dell Inspiron 3521. But first, I have to say something really important: Working inside a laptop can be tricky and potentially dangerous. If you’re not comfortable with electronics, it’s always best to ask a grown-up or a professional to help.
What’s a “Short”?
Imagine two wires that shouldn’t touch each other accidentally touching. That’s a short circuit! It can cause a lot of problems, like the laptop not turning on, overheating, or even getting damaged.
Finding the Short (This is where it gets tricky):
- Disconnect Everything:
- First, unplug the laptop from the power adapter and remove the battery. This is super important for safety!
- Open the Laptop:
- You’ll need a screwdriver to carefully open the laptop’s case. Be gentle, and look for screws. If you don’t know how to do this, look up a video on youtube that shows how to open your model of laptop.
- Visual Inspection:
- Look closely at the motherboard (the big circuit board inside). See if you can find any:
- Burned or melted parts
- Wires that are touching when they shouldn’t
- Anything that looks out of place
- Look closely at the motherboard (the big circuit board inside). See if you can find any:
- Multimeter (This is for grown-ups or people with experience):
- A multimeter is a tool that can measure electricity.
1 If you know how to use one, you can use it to check for shorts in different parts of the motherboard. But, it’s really easy to make mistakes with this tool, so be careful.

Fixing the Short (Even trickier):
- If you find a loose wire: Carefully move it away from anything it shouldn’t be touching.
- If you see a burned part: This usually means a component is damaged, and it needs to be replaced. This is a job for a professional.
- If you are not sure: If you can’t find anything obvious, it’s best to take the laptop to a repair shop.
Safety First!
- Always disconnect the power and battery before opening the laptop.
- Be careful when working with small parts.
- If you’re not comfortable, ask a grown-up or a professional for help.
Important Note: Laptop repair can be complex. There is a chance that you could cause more damage to the laptop. If you are unsure of any step, please seek professional help.
