Dedicated GPU
This is a separate powerful graphics card that handles advanced visual tasks. It has its own memory and significantly boosts performance for graphics heavy work.
Gamers and creators usually look for dedicated GPUs from NVIDIA or AMD.
Cooling System or Fan
Laptops generate heat while working. High performance tasks make the CPU and GPU work harder, which increases temperature. The cooling system keeps the laptop at a safe temperature.
Most laptops use one or more fans along with heat pipes. Some high performance models use advanced cooling such as vapor chambers.
If your laptop overheats often, it may slow down or shut off automatically. Cleaning dust from the fan can solve many heating issues.
Battery
The battery powers your laptop when it is not plugged in. Laptop batteries are usually made of lithium ion or lithium polymer. They are lightweight yet powerful.
Battery performance depends on capacity measured in watt hours. Higher capacity means longer backup. Software optimization also affects battery life. Gaming laptops usually have lower battery performance due to power hungry GPUs.
Wi Fi and Bluetooth Card
This component handles wireless connectivity. Without it, your laptop cannot connect to Wi Fi networks or pair with Bluetooth devices like headphones and keyboards.
Modern laptops use Wi Fi 6 or higher standards which provide faster internet speeds and better stability.
Speakers and Sound Card
Speakers output audio while the internal sound card processes audio signals. Premium laptops include high quality stereo speakers with richer bass and clearer sound. Budget laptops may offer basic audio, which can be improved with external speakers.
Internal Camera or Webcam
The webcam is placed above the laptop screen. It is used for video calls, online meetings and facial recognition features.
Resolution varies. Many laptops now include 1080p webcams for clearer video quality.
Optical Drive (Rare Today)
Older laptops included DVD or CD drives. Modern laptops have removed optical drives to make devices thinner and lighter. However, external USB DVD drives are available if needed.
