Hi samy007,

Tips to prevent your computer from overheating:

Proper placement.:

Locate your computer where the best airflow and least dust contact is allowed.

1. Place your computer a few inches from the wall.
2. Avoid positioning it inside a computer cabinet or directly onto the floor or carpet. It’s better to find a computer stand to elevate the computer several inches off the ground to reduce dust accumulation.
3. Keep the room temperature to a maximum of 75 to 85 degrees (Fahrenheit) and around 35% to 40% humidity level.

Check for proper airflow:

Make sure the computer vents and fans remain clean of dust which can prevent the heat and fresh air to pass through efficiently. Additionally, verify that all fans are spinning correctly without unusual noises.

Update the System BIOS:

An out of date BIOS can cause heat issues by having an outdated temperature table for the system.

I have also provided a link below for Bios update:

• During BIOS update verify that the computer is connected to an AC Adapter.
• Disconnect any third party peripherals connected to the computer before performing BIOS update.
• Do not turn off the computer during the BIOS update.
• Do not restart the computer during the BIOS update.

Note: Plug your computer to a good, working wall jack before you update the BIOS. If you experience a loss of AC power or a significant voltage sag/spike during the BIOS flash, you will either have to buy a new BIOS chip or buy a new motherboard.

The picture below shows the correct temperature while in operating state and when the system is idle:

Awaiting your response!

thanks for your reply

i am using cooling pad, all the time i use my laptop.....

its normal tempreture under normal usage is, 47 to 55 degrees.....

i am afraid of upgrading by bios, as i have read in some posts that it could creat many issues, like display problem, and other(dont knw  if they are true or not)

my rooms tempreture are also normal, here are summers nw, nd my rooms quite cool... never noted the tempreture

Lower temperatures are obviously better, but I don't think 78C is actually that bad (if that's during gaming)... my i5 will frequently get to 70C+, and my old laptop got much hotter. Mobile CPUs are designed to take a lot more heat than their desktop counterparts, and will also throttle if they get too hot. If they get to a dangerous temperature, they'll shut-down to avoid any damage. The i5 can apparently go up to 105C before shutting down (though it would be bad to run close to 105C all the time).

Other than what was mentioned above, there's one thing I can think of that might keep temps down - you could use a program like DXTory or MSI Afterburner to limit your framerate in games. It should stop the GPU and CPU from working at 100% all the time, and hopefully keep temperatures lower.

Personally I think your temperatures are fine, but it's probably better to get more opinions on it if you're worried... maybe try Googling for more information on your CPU's thermal limits/safe temperatures/etc.

thank u very very much... u made me feel alot good, as am really concernd with my laptop

in your oppinion should i upgrade by bios, as i m having truoble in just heat,....... nd my laptop had reached to 81c....
