In addition to Intel's Core i7-4900MQ CPU and Nvidia's latest Quadro K2100M pro graphics, it is primarily the extremely high-resolution QHD+ screen that stands out. It offers an especially big desktop owing to 3200x1800 pixels. This blaze of performance almost lets the 16 GB of working memory and the large 256 GB solid state drive fade into the background. However, the present Dell Precision M4800 workstation hp probook 640 g1 power supply is not a bargain with a current price of approx. 2850 Euros (~$3931, gross) and will likely only come into question for very aspiring home users besides the targeted professional user group.
Design
Dell designed the M4800 for function, not fashion. However, there is an understated elegance to its fingerprint-resistant, gunmetal gray, anodized aluminum lid. The chrome Dell emblem embedded in the center of the lid adds a nice bit of sparkle. The front of the lid has a soft curve that draws the eye to the lock button located on the front lip.Put to the test with our X-Rite colorimeter, it delivered a superb maximum brightness of and a fine contrast ratio of 820:1. Colour reproduction is superb, as you might expect of a screen aimed at professional hp 65w hp probook 650 g1 ac adapter charger designers, architects, videographers and engineers. It’s capable of reproducing the full sRGB colour gamut, and is magnificently accurate with an average Delta E of 1.7 and a maximum of 3.5.
We love the speaker grille positioned above the keyboard; its dash and dot design reminded us of Morse code. A set of dark-gray, chrome volume-buttons sits to the left of the grille with the power located on the right. Directly below the keyboard is a smallish touchpad surrounded by a luxurious black,soft-touch-finish palm rest.
The one caveat to all this is that - although Windows itself works fine - most applications have yet to be optimised for high-DPI displays. The result is either tiny, unreadable text in menus and dropdowns, or blurry icons and pixellated text as elements are scaled up. Some applications, such as Sony cinema hd display 90w power adapter Vegas Pro, deliver the worst of both worlds, scaling some elements up too much and leaving others absolutely miniscule. We’d prefer a 1,920 x 1,200 display in most situations, but, disappointingly, the only other resolution on offer in the Precision range is Full HD.
Dell hasn’t changed much about the chassis since the last time we saw one of its Precision workstations. It remains an absolute tank of a laptop, weighing 3.2kg without its charger - and a hernia-inducing 4.1kg with it. It feels built to last, though, clad entirely in thick, rigid-feeling anodised aluminium, and there’s plenty else to like.
Keyboard
Like in many other areas, Dell did not modify the input devices at all. The keyboard still features a crisp, quiet stroke, medium drop and firm impression. The layout, key size and special functions are good. The keyboard's netzteil asus ep121 backlight can be set in four levels and the dedicated number pad will prove to be convenient particularly when entering time-consuming rows of numbers.The physical volume controls in the top left are joined by WiFi, Bluetooth, disk access, and power indicators. The trackpad is disappointingly small but there are physical buttons for left and right clicking.
The keyboard is superbly comfortable, and is good enough to rival the best desktop models. Its soft, cushioned key action is a pleasure to use, and the size of the chassis means there’s room for a number pad to the right. There’s a trackpoint to supplement the small touchpad asus zenbook prime ux31a netzteil, and both work flawlessly. It’s nice to see separate buttons for both. We’ve yet to come across a buttonless touchpad that can match the comfort of an arrangement such as this.
Dell avoids the isolated-style keyboard, using a more traditional keyboard style. It squeezes a full-size number pad onto the side as well, and has a 'nipple' to control the mouse right in the centre, between the G and H keys.the keyboard its dash and dot design reminded us of Morse code. A set of dark-gray, chrome lenovo yoga 13 netzteil volume-buttons sits to the left of the grille with the power located on the right. Directly below the keyboard is a smallish touchpad surrounded by a luxurious black, soft-touch-finish palm rest.
Display
The M4800 is one of the first Windows workstations outfitted with a Retina-like display. The notebook's 15.6-inch, 3200 x 1800 matte panel is sharp and offers wide enough viewing angles to accommodate three people. However, similar to other Window 8 machines with ultra high-res displays, text is hard to read unless you're zoomed in past 150 percent.No corners have been cut to reduce the Dell Precision M4800's ac adapter tiny m92 physical size. A total of 11 status LEDs flicker on and off. There's a built-in optical drive, smart card reader, SD card reader, four USB 3 ports, with a further E-Sata/USB 2 port at the rear. There's also DisplayPort and HDMI rounded off by Gigabit ethernet as well. Dell has sensibly retained the analogue D-Sub connector, since the majority of displays and projectors in office environments still use this video standard.
When it comes to color and sharpness, though, Apple's Retina Display still reigns supreme. In an image of a German shepherd puppy in a flower basket, the MacBook Pro 15 delivered richer color, especially the blacks in the dog's fur and the vibrant fuchsia of the flowers. The same image on the M4800's acer a700 ladegerat matte display looked muted. In terms of sharpness, we saw the waxiness of the flowers and the puppy's individual hairs better on the MacBook. The dog's right-side whiskers were barely discernable on the M4800.The high resolution of 3200x1800 pixels leads to a very fine and detailed reproduction. The naked eye does not perceive single pixels. This also results in a lot of room on the desktop and easily allows placing several windows, documents and charts beside each other on the desktop.
However, one drawback is that fonts, icons, and menu positions are much smaller. That can be resolved by increasing the display size in the system control in many cases. But that does not always work and sometimes a magnifying glass is needed to see the necessary items depending on the program and window size. We will categorize this as "teething problems". It should ultimately only be a matter of time before high-definition screens become widespread and programs are modified for these displays.The Precision M4800 samsung ad 3014 has a seriously bright screen, registering 323 lux on our light meter. That's well above the 211-lux mainstream average. The MacBook Pro was a full 100 points behind at 223 lux. The ZBook 15 did somewhat better at 295 lux.
Performance
The main focus in a professional workstation is naturally placed on performance. Here, as expected from Dell, the user can basically draw on abundant resources. However, the choice of components is limited for single buyers and private individuals. Dell sony vaio netzteil vgp ac19v37 currently only offers three pre-configured models for this group of buyers which is nevertheless to cover a vast and particularly attractively priced spectrum. However, classic business customers and wholesalers can configure the laptop freely and implement special needs when they order a sufficient number of units.
The Cinebench 15 CPU score of 609 is just 6 points shy of the score achieved by an older desktop 3.5 GHz Intel Core i7 3770K Ivy Bridge CPU. A render test in 3D Studio Max was 30 seconds faster with the Dell Precision M4800 than the same desktop Intel Core i7 3770K processor. That's great news for 3D designers, since the high-end specification of the Dell Precision M4800 motion computing le1700 akku is perfect for use with software such as Solidworks, Maya and Nuke.The M4800's 256GB SSD took 30 seconds to load Windows 7 Professional, just missing the 29-second average. The ZBook 15 was a little faster, booting Windows 7 Pro in 25 seconds. The MacBook Pro started OS X 10.9 (Mavericks) in just 15 seconds.
Arguably, SSDs are now essential rather than a luxury, given the overall performance difference they make. The Dell Precision M4800 can be customised with an SSD boot drive and a hard disk in the secondary bay, which would undoubtedly be our preferred configuration, although this adds to the cost - £264 for the SSD and up to £98 for the 1TB hard disk.The biggest disappointment is the display. TN panels simply aren't very good, and may make you wince the moment the Dell Precision M4800 toshiba z830 battery replacement is switched on. With an IPS or IGZO display, you can expect viewing angles approaching 180 degrees, so when viewed from the side, the display looks identical to when it's viewed head-on. But TN panels looks darker from the side, and aren't as clear.
Our review sample is a pre-configured version and represents the present top model in this field. Dell installs a very high-performance processor with Intel's Core i7-4900MQ CPU. The RAM configuration of 16 GB is also attractively sized and the swift SSD storage device will usually suffice with a capacity of 256 GB. Nvidia's professional Quadro K2100M performs graphic calculations and the user can, as mentioned above, look at its results on the excellent QHD+ screen. Dell toshiba pa5013u 1brs alternatively offers two other professional graphics chips, innumerable storage devices and working memory options, many CPUs and smaller configuration details. The base price currently starts at 1419 Euros (~$1957, net) and is, as usual, open-ended.
Battery Life
The high-capacity, 97 Wh battery successfully prevents the runtime-calamity that is presumed at first. The laptop hp pavilion 27xi power supply shut down after 318 minutes in Battery Eater's Reader's test using minimum brightness, disabled wireless modules and maximum energy-saving options. The Wi-Fi test provides more practical figures. Almost exactly 3 hours of battery runtime, using brightness level 6, energy-savings mode and wireless on, at least allows being away from the outlet for a while. It is possible to watch DVDs for about the same time in brightness level 8 and with disabled wireless modules. The runtime nosedives in full load despite the lower performance of 20 to 30% and is only enough for almost 1:30 hours of work.
In battery life tests, the TN 1080p screen in the Dell Precision M4800 does seems to drain power less than the 3200 x 1800 QHD+ display. However, the improvement isn't huge. PC Mark 08 lasted for 2hrs 59 minutes, which is about 50% less than an Ultrabook manages.We don't expect marathon-like endurance from workstations, but the Dell Precision M4800's dell venue 11 pro charger 24w endurance was still disappointing. The machine lasted 4 hours and 16 minutes on the LAPTOP Battery Test (continuous Web surfing over Wi-Fi). That runtime is an hour less than the 5:35 mainstream average. The HP ZBook 15 lasted 7:46, while the Apple MacBook Pro clocked in at 8:02.
Verdict
In addition to its durable yet handsome chassis, the Dell Precision M4800 is a productivity beast. This workstation offers a powerful Intel Core i7 processor and Nvidia Quadro GPU, which can easily handle graphics-intensive tasks like video editing. We also like the comfy keyboard, sharp QHD+ display and robust audio. However, the M4800 dell charger la45nm131 is a little lacking when it comes to battery life.
All in all, the review configuration convinces with high performance that could only be better in demanding 3D graphics tasks. The fans that work very well during full load keep the casing's surfaces cool above the average and ensure unrestricted use of this workstation. However, the loud operating noise that can be very distracting after a longer time has to be accepted in this state.The disabled Intel HD Graphics 4600 dell precision m4800 power supply also has several adverse consequences. The power consumption during low load is high and thus the battery runtimes clearly remain behind the possibilities despite the high-capacity battery and Intel's QuickSync Video cannot be used.
The Dell Precision M4800 is hardly going to appeal to students looking for a laptop to take to college, but design professionals who need a portable machine with real 3D grunt will be pleasantly surprised by how capable it is. It's not a complete behemoth like other 17-inch mobile workstations.For $89 more, users can get the $2,599 15-inch Apple MacBook Pro, which offers nearly 9 hours of juice and more-lush Retina display in a lighter, sleeker chassis. However, you'll get far fewer ports and not nearly as many customization and security options. Ultimately, the M4800 is a strong choice for users searching for a notebook with power, durability and security.
