In regards to design and style, we’ve got had this situation in overview a couple of instances before. Starting with the T500 more than the T510 as much as the newest T4x0 sequence, Lenovo couldn’t compel to make any stunning style modifications in the current T520, other than CP500588-01 Fujitsu 65W Charger for small kinds. Viewed as by by itself, sticking for the attempted and tested isn’t at all poor, but innovations never cease in situation design. And compared to the competitors, you would believe that a high-priced notebook for instance the T520 would, in a sense, ought to have a comprehensive steel situation now, although.

Instead, Lenovo nevertheless sticks for the plastic appear & truly feel. However, the T520, practically dressed entirely in black includes a certain air of elegance and the matt somewhat roughened surfaces have a pleasant truly feel anyway.

The metallic hinges appear a bit modest in comparison for the laptop’s size. Having said that, they barely allow teetering after the opening angle has been adjusted. Nonetheless, they are not pulled tight enough to prevent the opening angle from Samsung S22D300HY Charger changing its angle in unstable situations (train journeys).

Gaming Verdict

Computer games will unlikely belong to the primary application field of an office device created for business use. Even so, they reflect the possible 3D performance of a computer quite well. Our expectations aren’t set very higher considering acer aspire 7750g akku/akku acer aspire 7750g/acer 7750g akku/aspire 7750g akku/akku acer aspire 7750g/akku aspire 7750g the hardware configuration as well as the 3DMark results. The 1 or other cultured game after work is possible. Nevertheless, the requirements shouldn’t be set beyond medium graphics details inside a modified resolution, depending on the game.


Value shouldn’t be placed as high in a business device as inside a multimedia or gaming notebook. The maximum volume is just sufficient for indoors as well as the sound remains undistorted. On the other hand, the sound proves to have poor bass.

In order to enjoy music, you need to therefore use external speakers or high-quality headphones.

The T520 stays all more than cool in idle mode. The temperatures rise with increasing load and it reaches the maximum temperatures inside the vent’s vicinity.

In order to estimate the maximum possible temperatures, we execute a stress test of several hours where CPU and GPU are loaded to 100% (Prime95 & Furmark). The wrist-rest and touchpad even remains pleasantly cool here. acer aspire 5750g akku/acer aspire 5750g akku original/akku acer aspire 5750g/aspire 5750g akku The CPU’s core temperatures climb to 86 degrees Celsius, the GPU’s to a maximum of 83 degrees Celsius, which are just as acceptable rates.

Battery and Energy Consumption

Our Lenovo ThinkPad T520 included the normal six-cell battery option, offering a 57Wh capacity.

An optional “slice” battery is also presented as an option for the ThinkPad T520, which when combined having a 9-cell battery boasts an impressive 24-hours of runtime. Sadly, we were unable to get a slice-battery with our overview unit, so we are unable to provide measured runtimes of that configuration.

To test the battery life we used the Windows seven Power Saver profile, together with the display backlight reduced to about 50% (9/15 brightness), Bluetooth disabled, Wi-Fi on and refreshing a webpage without animated or Flash-based ads, as well as the system set to hibernate at 5% power remaining. Our goal with this test setup is to try and mimicasus f551c akku/akku asus f551c/asus f551ca sx079h akku/asus f551c akku original/asus f551ca akku kaufen the road-warrior situation, where you are trying to squeeze as considerably time as possible in-between charges.
