There are 2 large chips located beneath a heat sink. One will always be the CPU chip the other the graphics chip. Both of these chips are very complex and produce a lot of heat during use. The graphics chip though generates the most heat. The CPU is almost always contained in a socket which allows it to be quickly removed and replaced should it fail or require upgrading. Unfortunately, upgrading or changing a faulty graphics chip is impossible or very difficult as it is directly soldered to the motherboard.
Graphic chips may fail or have a reduced life when they continually operate at a high temperature. So any measures that can be taken to keep this chip cool will extend the life-span of the laptop.
There are some obvious measures that can be taken to keep this chip cool and a few less obvious ones. Ensure that you do not block the air inlet and air outlet being specifically careful not to use the laptop on a fluffy surface like a bed or rug. If you notice that the air coming out of the exhaust outlet is slow or very hot then you will most likely have to have the fan and vents cleaned by a laptop repair agent. Different kinds of programs cause different amounts of heat being generated by the graphics chip. Letting the laptop idle on the web will not cause the graphics chip to generate much heat, however, playing a game where sophisticated graphics are operating will usually cause it to generate considerable heat. You probably will be amazed to discover that playing a DVD film can cause the graphics chip to run very hot, so potentially lowering the life span of the laptop especially if this is done regularly.
If the wrong or an outdated graphics driver has been installed on the laptop then this might cause the graphics chip to overheat and will likely cause graphics intensive programs to judder or freeze the laptop. Most laptop manufacturers provide a free service where the correct driver or drivers can be downloaded to maintain it operating exactly they intended when designed.
Upgrading the graphics chip on a laptop is normally almost impossible since it is very difficult to remove the old chip from the motherboard. You will discover though, a few high specification laptops which may have the graphics chip mounted on a separate sub assembly circuit board that connects to the main motherboard. This will make it easy, thought quiet pricey, to upgrade or replace the graphics chip as necessary.
Always treat your laptop with care, being aware that if it is getting too hot then your graphics chip may fail immediately or may have a reduced life. You may notice that your laptop is pumping out very hot air or maybe the case is getting far too hot to touch then it is extremely probable that the graphics chip will be just about to fail.
