First, I don't know if I should post this question in the External Hardware category or Internal Hardware, so I think I'll post it here. Second, I noticed my Laptop's charger pin is getting warm. I had this Laptop and its charger for the past 2 years with no issues and I use it for 3D modelling and graphics demanding games.

 

I just noticed today, that the laptop's charger pin was hot, but not hot that it can burn my skin, but hot that it felt like another person's skin, after a session of using Blender. Since the laptop is almost 2 years old, I'm worried that my laptop's charger might be over-stressed with the task of 3D Rendering. I do have a habit of leaving my chargers plugged into the wall, except for the laptop charger. Every time I know I'm gonna be gone from my room for more than 5 minutes, I unplug the charger from the wall and laptop, to sort-of let it 'rest'.

 

As of the time of the writing of this post, the laptop charger is currently plugged in and charging the laptop. It's currently only slightly warmer than my computer mouse, with the laptop not doing anything resource intensive. There has been no issues regarding charging(no sudden disconnections, or battery errors of any form).

 

I did read around Google that a warm laptop charger is fine, especially when the laptop is being charged and used at the same time. But since I use my laptop for 3D Renders, mine might be different.

 

It might help to say that the Charger Port is next to the Laptop's Exhaust, where most of the heat are in an Alienware 17R3.

 

Please tell me if I'm just being paranoid(Not an exaggeration)

It looks like you're meaning the DC plug connection into the body of the laptop, which can become somewhat warm, and if it is located as you say adjacent to the cooling air exhaust, then it's likely to be warmed a little by that also. From your description it doesn't sound like a problem to me, although one thing does sound unusual. When you speak about unplugging if you're out of the room for more than 5 minutes, do you mean you are repeatedly plugging and unplugging both the mains and DC plugs while the laptop is operating? If that's what you're saying, the plug might simply be getting worn and having a weaker contact internally, which can make it heat up more than it would when new and making strong contact.

Yes, I unplug it from both the Laptop and Wall Plugs, while the laptop is operating and has an almost full battery, I only leave it plugged when I leave if the battery is almost drained. The Charger's Pin is still holding in firmly at the port, I was very careful not to apply any kind of force that can make it loose or break the connection inside( A lesson I learned after the 20 USB cables I broke)

Yeah, I need to calm down a bit, until a problem actually arrives.

No point doing that, just wears the plugs. And possibly shortens battery life slightly, if it's a Lithium battery, which have a relatively fixed number of charge/discharge cycles governing their lifespan. You're best to let the battery fully charge, charging will then stop, lightening the load on the charger. Continually doing partial discharge and recharges when you don't really need to is just making the charger work a little harder and using up battery charge cycles.

I see what you're talking about, I'll do that. Thanks for explaining that bit, might help my battery and charger last for more longer now.
