The idea of switching from discrete to integrated graphics core in the chipset when switching to battery power is not new. However, the first implementations were not overly comfortable for the user, since they required a reboot. But already in 2007 year-to-date version of the Kite with the integrated chipset amd 690M in a pair could work a discrete graphics card, and switching between them takes place automatically and does not require a reboot. A year later, nvidia implement this functionality more in chipsets for desktop platform in a series of nForce 700a, though special popularity they have received, as were a number of restrictions, by the way, the user must switch itself was activated manually. But obviously, if the desktop platform is the result of an optional and more natural looking development of discrete graphics cards, taking into account the most effective reduction their energy consumption in idle mode. Then in a notebook any "watts" on the account, so a "lite" of the second video core for the foreseeable future will remain a popular decision, but rather will be used much more widely. We consider not just the typical version of such a design from Acer, which is used not mobile and desktop amd 780G chipset, combined with a mobile video core midrange Radeon HD4570. Speakers are located above the keyboard (built-in perforated decorative panel), so the sound quality does not depend on the location of the laptop, as is the case with models in which the speakers are built into the front face of the housing.
