Resolve HP 430 Notebook always overheat and shutdown suddenly

I have notebook / laptop from HP, model :  HP 430 with intel processor core i3. It was always overheat and shutdown suddenly. I already clean the ventilation and exhaust area from dust also cleaning the fan.
It still be overheat and shutdown after be cleaned.

The problem solved when I tried to update the BIOS version.
If you have the same problem, same with me, go to hp support website, download and install update for the BIOS.

The original link is :

After downloading, I install it and now the notebook is not overheat  and not Shutdown suddenly again.

Google calculator, the easiest.

When you are online on the Internet and need the calculator, just open and then search using  key word:  Calculator, then the Google web Calculator  will appear.
After Google web calculator appears, then you can use it, and although the internet connection is disconnected, you still be able to use this calculator. It needs Internet connection only when first loading.

Why Only hear the sound from one speaker in my iPhone 4 / 4S ?

When playing a music or sound in the iPhone 4 /4S, try to block the speaker hole (at the bottom of the iPhone) using your thumb or finger and you will know that only one speaker produces the sound, only the right side speaker. and the left side speaker does not work. why? is it a problem with your iPhone 4 /4S ?.

The answer is not a problem with your iPhone, because the left side is not a speaker, it is a microphone, for pick-up your voice when speaking.

Microphone and Speaker at iPhone 4
The microphone of course will not produces the sound :)
The iPhone 4 /4S only has one speaker.
