Welcome to a Laptop Battery specialist of the Dell Laptop Battery
The U845-S406 comes equipped with a 500GB, 5,400rpm hard drive and a 16GB flash cache, a one-two punch designed to deliver storage capacity without sacrificing brisk boot-time. The 16GB flash cache is invisible to the user, toiling behind the scenes during repetitive tasks and whenever the system is roused from sleep mode. The 500GB hard drive has plenty of capacity, though it comes stuffed with preloaded software. As is often the case, these programs range from useful apps (Microsoft Office Starter 2010, Microsoft Live Essentials) to needless bloatware ( desktop links to Skype and Amazon), with a slew of proprietary software (Toshiba BookPlace, Bulletin Board, Media Controller, and the like) and trial versions (30-day trials of Norton Internet Security, QuickBooks Online Banking).
The U845-S406's combined Intel Core i5-3317U 1.7GHz processor and 6GB DDR3 RAM with battery such as Dell GX047 Battery , Dell H766N Battery , Dell HD438 Battery , Dell HF674 Battery , Dell J399N Battery , Dell J590M Battery , Dell JD634 Battery , Dell KD186 Battery , Dell KD476 Battery , Dell KG046 Battery , Dell KM958 Battery , Dell MM165 Battery yielded steadfastly average results in our benchmark tests. Its PCMark 7 score of 3,946 outperformed most comparable systems, save for the HP Envy 4-1043cl $829.99 at HP(3,962) and the Toshiba U845W-S410 (4,652). Similarly, the U845-S406 almost always landed in the middle of its class in our multimedia tests. It completed our Handbrake video-encoding test in 1 minute 57 seconds, outpacing the Lenovo IdeaPad U310 $729.99 at Walmart.com(2:03) while falling short of the Satellite U845W and Inspiron 14z (1:58, each) and, to a much larger extent, the class-leading Asus UX32VD-DB71 (1:43). Its Cinebench R11.5 score of 2.41 is competitive, but nonetheless fell far behind the Asus UX32VD-DB71 (3.58). The U845-S406 completed our Photoshop CS5 test in 4 minutes 33 seconds, still falling short of the Asus UX32VD-DB71 (3:58) and, to a greater extent, the Toshiba U845W (3:42).
The U845-S406's integrated Intel HD Graphics 4000 GPU churned out 3DMark 06 scores that, for the most part, fell short of its peers (5,792 at medium detail settings and 1,024-by-768 resolution; 3,278 at native resolution with 4x anti-aliasing). Accordingly, the U845-S406 trumped the Lenovo IdeaPad U310 (4,978 and 2,672, respectively) but was still bested by most others in its class, particularly the Inspiron 14z (6,031 and 5,510, respectively) and, by a significantly wider margin, the Zenbook Prime (8,627 and 5,148, respectively).
