If you fancy a notebook that will keep you connected, productive, and entertained on the go, the Dell Inspiron 1520 is quite a compelling option. Featuring a more attractive design than the E1505, with rounded edges and your choice of eight colors, this notebook packs a speedy Intel Core 2 Duo processor, 802.11n and Sprint's EV-DO Rev. A connectivity, as well as discrete graphics. Dell also goes the extra mile by offering 3GB of free online backup, the choice of ordering your system free of trialware, and--for the first time ever on a Dell consumer notebook--3G mobile broadband. We just wish it were more travel-friendly.
 
With the 1520, Dell ditches the familiar (but heavily aged) silver-with-white-trim look for one that has more flash. Our model came with a colorful soft-touch Ruby Red lid, but you can also get it in Jet Black, Alpine White, Espresso Brown, Flamingo Pink, Midnight Blue, Spring Green, and Sunshine Yellow. We were disappointed that the interior didn't offer as much flair as the exterior, but removing the white plastic bumpers found on the E1505 was a step in the right direction. We would like to have seen a sleeker chassis; at 6.7 pounds and measuring 14.1 x 10.6 x 1.5 inches, the 1520 is hefty compared with other 15.4-inch notebooks. But with that heftiness comes a solid build that feels like it can take a few bumps (view photo gallery).
 
The 15.4-inch (1680 x 1050-pixel resolution) display looked good from a variety of angles, whether we were surfing the Web, viewing photos, or working in Word docs. We noticed that flesh tones were a bit muted when we watched DVDs, however. Beneath the LCD sits a full-sized, flex-free keyboard that was comfortable to use even for extended periods. The touchpad is plenty big  nd features firm, quiet mouse buttons.
The Inspiron 1520 uses li-ion, 11.1V, 49WH standard system inspiron 1520 battery as power supply unit, it has a long battery life. for more info about inspiron 1520 battery tips,click the link below:
