Welcome to a Laptop Ac Adapter specialist of the Sony Ac Adapter
The IdeaPad U300s is Lenovo’s very own sampling in the ultrabook category. The model got its inspiration with Lenovo’s earlier ultraportable laptops, starting with the smaller IdeaPad U150 and the 12.5-incher IdeaPad U260. The U300s i basically a souped-up but slimmed-down version.
Unlike other ultrabooks that try to taper the edges making the notebook look slimmer than it actually is, the IdeaPad U300s is flat all across giving it an impression that it is thicker and heavier than the rest. In some respects, that is true but if we take the measurement of an ultrabook’s thinness from the thickest part of the base, then the U300s can hold its own.
The metallic, matte finish of the lid spreads all around the body with a thin protrusion around the edges that helps in giving you a firm grip whenever you open the lid. The full-sized ports (the body design gives it that advantage with battery such as Sony ACC25 Ac Adapter , Sony VGN-FZ Ac Adapter , Sony PCG-FR Ac Adapter , Sony VGN-CR Ac Adapter , Sony PCGA-AC51 Ac Adapter , Sony PCG-V505 Ac Adapter , Sony VGN-B1VP Ac Adapter , Sony PCG-Z1RA Ac Adapter , Sony VGN-TX Ac Adapter , Sony VGN-U8 Ac Adapter , Sony VGN-X505 Ac Adapter , Sony VGN-TX690 Ac Adapter instead of the tapered design that forces other manufacturers to use a mini or micro-sized ports) are all situated on the left and right sides of the laptop.
The screen used on the U300s is of glossy finish and this provides a bright and crisp display. The resolution is only 1366×768 pixels though and while it is decent enough, we would have wanted to see higher resolution (like the 1600×900 pixels on the UX31 or the 1440×900 pixels of the Mac Air 13).
One of the nicest and most comfortable keyboards on a laptop are designed by Lenovo and they were able to use this on the IdeaPad U300s. The keyboard has fairly-sized keys that are generously spaced apart. The keys are soft, responsive and laid out very neatly for comfortable typing. The only thing missing that we really wanted to see was the back-lit feature.
The generously-sized trackpad is smooth, responsive and comfortable to use; the sensitivity is just right and we’ve not experienced a lot of jerkiness or unwanted mouse commands.
Almost all of the processors used by ultrabooks are identical — an Intel Core i5 with 2 cores and 4 threads. The same is true with the the GPU since that one is embedded with the Intel chip.
