One of the highlights of the Precision workstations with Nvidia Optimus is their outstandingly low system noise,HP Compaq nc6300 Battery which we also observed with this 17-inch review model. Many less demanding tasks like Office, internet, video conversations or undemanding image editing can be performed almost silently thanks to the solid state drive and an inactive fan.HP Compaq nc6320 Battery The only thing you can hear, if your surroundings are quiet, is an occasional, barely perceptible chirp from the SSD electronics. When somewhat more demanding work is being carried out or if tasks are being performed in parallel, the fan switches on and murmurs to itself, audibly but quietly, at a level of 33.1 dB(A). The optical drive is a little louder at 34.7 dB(A), but overall it is still relatively unobtrusive, and is certainly masked by the background audio when you play films, if not before.HP Compaq nc6400 Battery
With moderate stress, such as purely CPU conversion, you should expect 40.5 dB(A). If the graphics unit is asked to perform on top of that, the most you will have to endure is 42.3 dB(A). All these readings can be classified as ‘very good’, and are appropriate given the performance requirements at that time. We did not notice a high-frequency or otherwise unpleasant sound coming from the fan at any time.IBM ThinkPad R60 Battery
IBM ThinkPad R60e BatteryCooling of the internal components is ensured by two large fans, which do an exemplary job of handling the heat build-up from the CPU and GPU. The case temperatures that we measured reached a maximum of 42.1°C after continuous stress. That’s not just a low value for a workstation, but also comes in below many multimedia notebooks which have considerably less power under the hood. We did not observe any throttling as a result of higher temperatures.IBM ThinkPad T60 Battery
The built-in speakers provide a decent basis for audio output, IBM ThinkPad T60p Battery making a pleasant change from the usual standard. Mid-tones and bass tones are present, and offer sufficient space to keep the audible high-tones in check. So with the usual changing of settings on the equalizer, it is possible to achieve a relatively balanced sound. But for bombastic cinematic sound or for audiophiles to enjoy the listening experience, you still have to turn to external solutions. These can be attached via USB or the 3.5 mm audio port. Additionally, the HDMI and DisplayPort connections allow a transfer of sound to external monitors and TVs (not tested). We liked the separation of the audio input and output, so that headsets with two jacks can be used.Lenovo Thinkpad R500 Battery
The possible battery options for the Precision M6600 are limited to two models with 9-cells,Lenovo Thinkpad W500 Battery according to Dell’s spec sheet. You can get the standard version with a 97 Wh capacity, as with our review model, or a battery with an 87 Wh capacity and 3 years’ hardware service. We would have thought the lighter 6-cell battery from the Precision M4600 would also fit; it could be for marketing or for technical reasons that this is not offered for the larger workstation as well. We were not able to test this.Lenovo Thinkpad T500 Battery
The minimum power consumption measured by us was 9.4 Watts, almost three Watts less than the smaller Precision, despite the larger display. But at medium and maximum settings without system stress, the values match up again (from 18 to 19.8 Watts), and with full system load the review machine allows itself about 30 Watts more on account of its more powerful graphics chip, hitting a maximum of 186 Watts.IBM 40Y6799
This only has an effect on the battery life in the impractical scenario of energy-saving mode plus the lowest brightness setting and energy drains turned off (WLAN etc). IBM ASM 92P1138 This situation is simulated by the Battery Eater Reader’s test, and gives a maximum battery life of 680 minutes in this case. The screen brightness is 21 cd/m² at this point and would be enough to read by even in a dark room. But if you use the WLAN module, increase the screen brightness to about 200 cd/m² (level 9) and select the balanced energy profile, then a battery life of 421 minutes is possible. IBM ASM 92P1140
When playing films at full brightness the laptop can last for over 5 hours, with all contents being handled by the Intel HD Graphics 3000. IBM ASM 92P1142 In the Battery Eater Classic test (high-performance profile, maximum screen brightness, everything on) the battery run-time benefits from the reduction in speed of the Nvidia GPU to 162 MHz in battery mode. So 64 minutes was possible, instead of the purely mathematically possible run-time of less than half an hour.IBM FRU 42T4504
Dell has created a very attractive piece of kit in the Precision M6600 mobile workstation.IBM FRU 42T4513 Fundamental aspects such as performance, quality and connectivity are dealt with effortlessly, with users having to accept very little in the way of limitations. The only compromises you have to accept are the flexing keyboard, the lack of a modular bay and the reduced graphics performance when on battery power. You are compensated for these by the great variety of configuration, support and warranty options, which allow you plenty of room to shape your own machine and leave little to be desired.IBM FRU 42T5233
The FullHD display is likewise of a very high quality, and is convincing in almost every area. The only issue is the lack of an option to have your Precision fitted with an RGB LED display, which will be a disadvantage for some professional users.IBM FRU 92P1137
On the other hand the system noise, optimally matched to every work situation, is absolutely without any disadvantage. From silent up to clearly audible, it is never disruptive, and has no negative effect on the case temperatures, which are also low. Nvidia’s Optimus technology ably demonstrates what can be achieved when it is combined with a well-conceived cooling system.IBM FRU 92P1139
While the unwieldy case size and heavy weight is a bad starting point for portability, the battery life, again thanks to Nvidia’s Optimus and in spite of the powerful hardware, is very impressive. With run-times starting at one hour and going as high as 11 hours, you are suitably equipped to cope with a range of situations away from the power socket.IBM FRU 92P1141
It is clear that all this good stuff has to be paid for with costly additional charges, bringing the price way over 4000 Euros (base model starts at around 1500 Euros). But you do get a 3 year warranty as standard, and therefore 3 long years in which to nurse your bank balance back to health.Lenovo Thinkpad R400 Battery
Very comprehensive range of configuration options, large choice of different hardware, very low noise with light use, very good battery life with light useLess expensive base models (particularly as there are no 17” Latitudes), the option of an RGB LED display, a modular bay What surprises us How low the system noise can be kept despite the notebook’s powerful components, thanks to Optimus and a successful cooling system.Lenovo Thinkpad R61 Battery
True Ultrabook experience. The Ultrabook market is still at its infant stages, but Asus have thrown everything they can to make the best first impressions with their ultrathin Zenbook lineup. Find out here if this sleek, 13.3-inch full magnesium alloy notebook is worthy of the Ultrabook name and the $1000 price tag.Lenovo Thinkpad R61i Battery
After the impressive UX21, can lightning strike twice for Asus with this larger 13.3-inch offering?Alongside the Acer Aspire S3, The Asus UX31 is one of the first Utrabooks to hit the market and actually launched within a week from the Acer Ultrabook in the United States. Two sizes are available at the time of review, the 11.6-inch (UX21) and the 13.3-inch (UX31), each marketed with the humble “Zenbook” moniker.Lenovo Thinkpad T400 Battery
The review below will cover the UX31E-DH52, available now for $1099. Another model, the UX31-DH53, is also available with double the SSD capacity of the review model on hand, but costs around $300 more. Otherwise, both models are essentially analogous.Lenovo Thinkpad T400 Battery
