The Battery Eater Readers Test shows that the battery life is around half an hour longer compared to the N76VM and half an hour shorter in the Classic Test. Toshiba L600D-07B battery While the former battery life improvement could be due to the missing second hard drive and a lower power consumption of the Nvidia GPU in standby mode, the increased power consumption in the Classic test can presumably be traced back to another GPU-CPU dependency. As the GPU often tends to slow the frequency down to 135 MHz, the CPU may activate the turbo mode more often and therefore increase the overall power consumption. The W-LAN and DVD test didn't come up with anything new. The test results are within the usual observational error. Toshiba L600D07B battery

Nvidia's Geforce GT 650M goes well with the Asus N76 and thus furthermore upgrates the multimedia notebook. Many games now perform in high quality setting and/ or native resolution without any issues. The significantly increased 3D graphics performance of the tester comes together with higher but still moderate air fan activity during maximum performance. The heat development therefore only slightly changes and doesn't have further effects. Toshiba A660D battery

Furthermore the features of both testers N76VM and N76VZ are identical. Display and sound are very good and the not so great touchpad and limited mobility continue affecting the overall ranking in a negative way. Altogether, the N76VZ is the more recommendable multimedia notebook, because the surcharge for the Nvidia Geforce GT 650M is currently around 10 EUR and therefore very low compared to other equipment options (N76VM-V2G-T1008V to N76VZ-V2G-T1011V).

The Vaio E-Series is known for notebooks, which are intended for daily usage as well as for leisure and work. Sony´s models offer sizes of 11.6 inch, 14 inch, 15.5 inch and 17.3 inch. We will test a representative of the 15.5-Inch-Models. TOSHIBA L745 battery

Our test-device is powered by an Intel-Core-i5-3210M-Dual Core processor. TOSHIBA L745D battery It is able to make use of 6 GB RAM. The graphics will be handled by the AMD Radeon HD 7650M-GPU. The data and application will be saved onto a 750-GB-HDD. It also comes with a DVD-burner. The notebook is also available in a diversity of other configurations. Competitors of the Sony notebook are the Lenovo IdeaPad Z580 (Intel Core i5-3210M, Nvidia GeForce GT 630M) and the Asus K55VM-SX064V (Intel Core i7-3610QM, Nvidia GeForce GT 630M). TOSHIBA L730 battery

Note: We tested with a pre-production model. This model was equipped with a Intel Core i5-3210M processor (2.5 GHz, Ivy Bridge). However, the serial model comes with a Intel Core i5-2450M-Prozessor (2.5 GHz, Sandy Bridge) on the market. Why Sony is using an old processor, we do not know. We have tried to repeat the Benchmarks with the serial model. It will be mentioned at the corresponding places of the review. TOSHIBA L735 battery

The Sony SV-E1511V1EW is completely made of plastics. TOSHIBA L740 battery The upper side of the base unit and the rear side of the lid are made of a matt white plastic. The upper edge of the base unit (about 3.5 mm), the display frame as well as the sides of the base unit are made of a shiny black plastic. In general the casing gives a frim impression. The palm rest bends a little bit under a load, while the keyboard bends considerably more. Especially at the upper edge near the F-keys the keyboard is very loose. While using the 'E','R' and surrounding keys, the keyboard is rattling. This rattling occurs on the serial model but not on the preproduction model. It appears as if a keyboard screw or a fastening clip has been forgotten at this location of the serial model. Presumably this mistake is only present in our test device. TOSHIBA L750 battery

When lifting the open notebook at the two opposite corners, the case warps just a little bit. The lid can also be warped a little bit. The hinges hold the display firmly in position. Opening the display with one hand is not possible, because then the base unit will lift up. The hinges are too tight for this. In total the manufacturing of the preproduction model and the serial model are identical. TOSHIBA L770 battery

On the left side of the notebook is one USB 3.0 port. TOSHIBA L755 battery Who wants to connect the device to a flat screen at home will be pleased about the HDMI output. Furthermore a VGA output, a Gigabit Ethernet port and a power socket have been put on the left side by Sony. The two audio jacks (microphone, headphone) have also found their place here. On the right side three additional USB ports are situated. However, these just support USB 2.0 standard. A socket for a Kensington Lock can be found on the right side too. A DVD-Burner is located in between the Kensington Lock and the three USB ports. On the front the User encounters two card readers. One for SD cards, while the other supports Memory Sticks, Memory Sticks Pro and Memory Sticks Pro Duo. TOSHIBA P700 battery

The WLAN module of Sony's notebook originates from Atheros and is called AR9485WB-EG. TOSHIBA P740 battery This module supports standard 802.11 b/g/n and is also able of the function Wi-Fi Direct (facilitates the direct connection between two devices without intercalated router). Connection with a hard wired network will be handled by a Gigabit Ethernet chip made by Realtek. It is one of the most used exponent of the RTL8168/8111 family. Concerning the Bluetooth chip Sony again uses one of the company Atheros and equips an AR3012 module, which supports Bluetooth standard 4.0. TOSHIBA P740D battery

The Sony SV-E1511V1EW is delivered with pre-installed Windows 7 Home Premium (64 bit) to the customer. A Windows 7 DVD is not included. The recovery of the System can be done with the help of the recovery partition. In addition a recovery DVD can be created with the use of a Sony tool. TOSHIBA P750 battery

Sony has pre-installed some programs: For the internet security the program McAfee Internet Security is responsible. With the use of McAfee Online Backup personal data can be stored in the cloud. The playback of DVDs is covered by Cyberlink's Power DVD 9. The programs ArcSoft Magic-i Visual Effects 2 (image alienation) and ArcSoft Webcam Companion 4 (webcam software) are interesting for webcam users. TOSHIBA P750D battery

Microsoft Office 2010 Starter, Windows Live Essentials 11 and Skype can also be found on the hard drive. Next to these, Sony installed several tools of its own, some of which are very useful. For example, 'Vaio Smart Network' allows to quickly turn the network connections of the notebook on or off. TOSHIBA P770 battery

System recovery
Above the keyboard are three special buttons: TOSHIBA P770 3D battery The button 'Vaio' starts the 'Vaio Control Center', while the button 'Web' opens the default web browser. The button 'Assist' opens a collection of Sony programs. This provides tools for searching and repairing of problems as well as a tool for creating a recovery DVD. The button 'Assist' offers an additional function: When this button is pressed while the notebook is off, the Vaio Care Rescue system starts. This system enables the possibility of resetting the notebook to factory defaults. Windows 7 as well as all drivers and programs will be re-installed. But be careful: All personal data and settings will be deleted. TOSHIBA P770D battery

Maintenance
The possibility of maintenance is limited. Underneath the device are two maintenance panels. Toshiba L730 battery One of these panels allows to access the hard disc, which can be exchanged easily. Therefore two screwdrivers are needed (different screw types are installed). Behind the second maintenance panel the RAM sockets can be found. Our test device is equipped with 6 GB RAM, while a maximum of 8 GB is supported. Access to the fan or the WLAN module is not possible. Toshiba P740 battery

Warranty
Sony provides the SV-E1511V1EW with a one year 'Bring-In' warranty. Customers must send their notebook to Sony in case of problems. Buyers that bought the notebook from a Sony Germany partner (e.g. Cyberport, Notebooksbilliger.de) can obtain an additional twelve months warranty. In order to get this, buyers must register on the Sony website within 8 weeks of purchasing the device. Otherwise the additional warranty will expire. A warranty of two years should be standard in case of a notebook in this price category - without separate registration. Not every customer knows or thinks about this. Toshiba L740 battery
