Laptops are bound to get hot. It has a lot of parts crammed up in a little space. Besides some laptops come up metallic cases. This causes more heat. That does not mean your laptop is having any issues as such.
You may check if your computer reaches unsafe temperature conditions. You may install Core Temp CPU Monitorto check for it. You can enter the value for safe temperatures in the monitor so that the laptop can come up with a pop-up message or go into hibernation if it reaches unsafe conditions.
Other options could be -
Keep it away from hot climate
Summer temperatures could be the culprit if you observe extreme heat. Make it a point to keep it in shade.
Use lap desk
You are expected to keep your laptop on a flat surface. This will help you get proper air flow to the bottom of the laptop. When you keep it on a fabric on your lap, it restricts the air flow and hence the heat is transferred to your body.
Keep your legs apart
Though it may appear a funny idea, you may consider sitting with your legs apart when you have the laptop on your lap. The gap between the legs will let you have proper air flow since the vents are not blocked.
Fan speed control
Have a control on the speed of your fans. There are programs like SpeedFan which help you achieve it. HP laptops have an app named HP CoolSense for the purpose.
Control the processes
Check for resource intensive programs. Try to keep such apps to a minimum. For instance, flash content makes your laptop work harder. This can cause your laptop getting hotter. Use flash videos only when you need them.
Another method would be to check the processes running in the background. If you are on Windows press ctrl+shift+esc to access Task Manger. Check if anything is using your CPU. If the CPU usage shows two digits for any of the processes, that process is the culprit.
These are some options to avoid heating up of your laptop. The actual reason could well be much different than that stated above. If all these tips tend to go flat, get your laptop checked by the authorised service center.
