The situation becomes worse if the system is under stress or is processing graphic-intensive work. Fan noise becomes much louder, but not to the point where it may become bothersome to the user in a normal office environment. Dell Latitude X1 battery However, during use where low ambient noise levels are preferred, such as a movie or video, the increase fan speeds could potentially be distracting.Dell Latitude D531 battery In a classroom or library environment, we would definitely suggest putting the X121e in power saver mode to avoid any possibilities of disturbing others.Dell Latitude D820 battery At idle with maximum energy saving options, the upper base surface of the laptop stayed relatively cool at an average of about 30 degrees C while the lower portion was slightly warmer to the touch at an average of 31.3 degrees C. Room temperature during temperature testing was at 23 degrees C. Dell Latitude D830 battery When stressed under FurMark and Prime95 for over 2 hours, the system can get quite hot! At worst, the notebook peaked at 44.8 degrees C on the bottom front center. Dell Precision M65 battery In fact, the bottom surface is almost 5 degrees C warmer on average than the top keyboard surface. While the top is not hot enough to warrant any concerns, users may find it too hot to use on their laps for an extended period of time when the system is under load. This is in contrast to the Fusion-powered X120e, which stayed relatively cool even during stress testing.Dell Latitude D620 battery A throttling test was performed by stress testing with FurMark and Prime95 for almost 3 hours. FurMark was unable to recognize the integrated Intel HD Graphics 3000, but was nonetheless able to stress the GPU. Dell Latitude D630 battery Background temperature during the throttling test was 18 degrees C. According to HWiNFO, GPU speeds fluctuated between 800MHz and 950MHz, which was expected since Turbo Boost is supported up to 950MHz. Dell Latitude D640 battery Otherwise, no throttling was observed during the testing duration. The PCMark06 score immediately following the stress test was 2911 points, which was in the same ball park as the initial score of 2962 before stressing. Dell Inspiron 1200 battery The X121e includes a pair of stereo speakers on the bottom of the tapered front of the notebook. Although a somewhat odd placement choice, the idea is that sound will direct towards the table surface at an angle before reaching the user. This placement was used for the X120e and is common for the ThinkPad Edge series as well. Dell Inspiron 2200 battery Sound quality is somewhat acceptable and on par with the E125. As expected, sounds lack bass and are a bit muffled, so these aren't exactly the best speakers for listening to music. Dell Inspiron 1300 battery The notebook can get quite loud at maximum volume although external speaker solutions will be required for more agreeable quality and range, of course. As previously mentioned, the 3.5mm combo audio port on the left side of the laptop will allow for earphone and speaker options without any problems. Dell XPS M1210 battery Classic TestThe reviewed model is equipped with a 6-cell battery module providing 11.1V at 5.16Ah. According to the BatteryEater Reader’s Test, running the X121e on battery can last for up to 461 minutes, which is quite good given the CPU performance increase over the X120e. Dell Latitude D420 battery These numbers were attained by enabling “energy saving” profiles, disabling wireless connectivity, and setting minimum brightness levels. Recharge time from zero to 100% is around 190 minutes. Dell Inspiron 6400 battery The minimum battery life, recorded with the BatteryEater Classic Test, was about 203 minutes. This was with full brightness, all wireless settings enabled, and the “high performance” profile setup. Dell Inspiron E1505 battery A more reality oriented battery life test was also performed at a brightness level of 13/15 under typical web surfing conditions with occasional videos and Adobe Flash enabled. Dell Inspiron 1501 battery The notebook reached up to 309 minutes just before the 5% battery notification box appeared. This is highly variable, however, since watching any sort of video will greatly reduce the battery life. Dell Latitude 131L battery In our X120e review, we noted that the 6-cell battery protruded from the rear, Dell Latitude C400 battery which definitely took away from its overall design. Thankfully, the 6-cell battery of the redesigned X121e fits snugly on the back with no unattractive extra volume. Perhaps more surprisingly, the X121e can last for almost an hour longer during the BatteryEater Classic Test compared to its predecessor.Dell Vostro 1000 battery The power consumption at idle and at the lowest brightness setting is around 6 watts according to the built-in Lenovo Power Manager. Under load and maximum brightness, the total power draw peaked at about 31 watts.Dell Inspiron 630m battery
