Dell Latitude XT is nowhere near the term of high performance because what it strives for is different. But there still are interesting points left to look at. Later on you will see how this not so high spec help battery life and heat on this machine.

<p><strong>Heat & Noise</strong></p> <p><img height="218" alt="Dell XT - HWMonitor" src="http://mycapsules.com/sites/default/files/2008/11/dell-xt-2/image_22.png" width="456" align="right" border="0" /> Wow!! This is one of the coolest laptops I have so far. I almost feel nothing throughout palm rest, keyboard, and on the screen. ULV CPU and thoroughly designed air ventilation should be the main factor here since at air vent on the left, hot air is coming out continuously (but still pretty silence) keep laptop at the minimal temperature. On the screen, there is no hot or even warm surface found!! Inside, as you can see on the right, maximum temp is only 152°F/67°C </p> <p>Consequently, temperature on the outside surface is not hot too. Please note that all data are in °F (+/- 1.5°F) and measure while this is on battery working normally about 30 min or so.</p> <div style="font-size: 0.8em; margin-bottom: 1em; font-family: verdana,arial" align="center"><img height="225" alt="Dell Latitude XT - surface temp" src="http://mycapsules.com/sites/default/files/2008/11/dell-xt-2/temp-surface_3.jpg" width="300" border="0" /> <img height="225" alt="Dell Latitude XT - surface temp" src="http://mycapsules.com/sites/default/files/2008/11/dell-xt-2/temp-surface2_3.jpg" width="300" border="0" /> <br />[Note: ambient temp = 83°F/28°C; low = 88°F/31°C; high = 101°F/38°C]</div> <p><strong>Battery Life</strong></p> <p>Battery on Dell Latitude XT is normal, nothing interesting or fantastic about, almost 3 hours on 6-cell, 42Wh. While it could have achieved better using ULV, it is disappointing because it constantly drains out 13W as a minimum which is considering very high at idle. No matter how I configure, that's the best I could get. Turning screen off helps decreasing 4-5W; turning others off help only about 1W less totally. As a result, Dell XT realistically last a tad shorter than 3 hours. That is ordinary, but not good as far as portability is concerned. 2 hour and half--oh boy! way to less!! since you shouldn't drain out battery every time.</p> <p>Besides, a bit short battery life. Dell provides such a portable power adapter instead. Light and thin as you saw earlier in this review, it comes with only 45W while regular laptop/tablet PC power adapter is about 65W or so. Does that effect how long to fill Dell XT up? We'll see.</p> <p><img height="335" alt="image" src="http://mycapsules.com/sites/default/files/2008/11/dell-xt-2/image_25_0.png" width="400" border="0" /> </p> <p>This is from Performance Monitor which I use to track all data, this time it's charge rate (red) and remaining capacity (green.) I could classify how fast it can charge into 3 situations:</p> <ol> <li>Charging while using, charge rate will vary between 21-23Wh which taking about 2 hours from 0%-100% </li> <li>Charging while turning on but screen off, charge rate will increase to 27Wh since it doesn't have to provide juice for monitor. This will help shortening charge time a bit. </li> <li>Charging while sleeping/turning off, this indeed helps charging much faster by only a bit over an hour with 35Wh charge rate. </li> </ol> <p>As you see, the screen sucks only about 4-5W an hour as same as others tablet PC's. That means ATi chipset (GPU + Northbridge + Southbridge) is the only thing to blame here. Dell should have go for Intel chipset here, so that they could at least give LV CPU as an option while consuming less or equal to what Dell XT is right now.</p> <p><strong>Service</strong></p> <p>This is hell good of service from Dell Business, although it could be whole different if you have consumer model. The thing is Dell has both live chat and telephone service which are nice. Also, you can even ask for a replacement to do it on your own. Don't have to mess or take any risk sending to repair center since according to my experience, sending anything to any repair center does not help really, including Dell.</p> <p>Almost anything they cover they will send you a replacement promptly, mostl
