This CPU is an entry level solution that contains Intel's HM57 chipset with a clock rate of 2x 2.4 GHz, a 3MB L3 cache and Hyper Threading support. Today, it is replaced by the more modern Core i3-2310M Sandy Bridge processor that includes the HM65 chip. Acer Aspire Timeline 3810 battery

The 1540 uses the Intel GMA HD embedded in the processor as the graphics unit. It is specially designed for office applications. The new processor's graphics makes a stronger impression and it also feels comfortable in the world of multimedia, including 1080p rendering.Acer Aspire Timeline 3810T battery

The Intel Core i3-370M achieves 7536 points in Cinebench R10's (64 bit) multi-thread processing and is on a par with the newer Intel Core i3-2310M. The Acer Aspire 3750 or the Sony Vaio VPC-EH1M1E/W is for example in its immediate vicinity. Overall, it shows a good computing performance, whereby efficiency also plays a role. But more about that in the course of this review.Acer Aspire Timeline 4810 battery

The processor-incorporated Intel GMA HD Graphics finds its limits in the synthetic gaming benchmarks. The notebook moves in the lower third of our database with a result of 1559 points in 3DMark 06. Acer Aspire Timeline 4810T battery

Current Sandy Bridge notebooks with the advanced Intel GMA HD 3000 Graphics score twice as well on average. Lenovo's ThinkPad Edge E320 manages 3098 points and therefore bids a performance advantage of 199%. Both solutions aren't suitable for gamers. However, in particular multimedia applications are possible with the faster GPU.Acer Aspire Timeline 5810 battery

The cross-component system benchmarks, PCMark Vantage and PCMark 7, confirm the lower midfield performance image that lacks performance reserves. Nevertheless, the given performance is more than sufficient for simple office applications.Acer Aspire Timeline 5810T battery

Dell has three different memory medium alternatives available for this range. In addition to a hard disk with 250 and 500 GBs, there is also the midway with 320 GB that we tested. The installed Western Digital Scorpio Blue, model WD3200BPVT-75ZEST0, works with 5400 rpm and is connected via a SATA II connector. Acer Aspire 5740DG Battery  

The performance isn't anything special with average access rates and a maximum transfer speed of 83.9 MB/s (CrystalDiskMark). However, the price-performance ratio is all right in this series. Exchanging the hard disk is quickly accomplished - but removing the wrist rest isn't as convenient as an own maintenance cover on the case's bottom would be.Acer AS07A31 battery

The built-in case fan, the memory medium and the DVD drive are potential noise makers in the Vostro 1540. The noise level is consistent with 30.5 dB (A) in idle mode, whereby the fan is inactive. Acer AS07A32 battery

Merely the hard disk is noticed in this scenario with 31.2 dB (A). Basically, a satisfying result as you would expect in an office notebook. The device attracts attention during load and when the DVD drive is used. It is very audible with a maximum of 39.1 dB (A). The fan's fairly rapid decrease in speed after finished work is positive.Acer AS07A41 battery

The temperature development on the case's outsides is acceptable for this configuration. The case remains within a pleasant range with a maximum of 30.7°C in office mode. Subjectively, these rates are perceived as lukewarm. Acer AS07A42 battery

Of course, the components' temperatures increase during load. We measured the peak rate of 38.5°C on the bottom, in the fan's area. This fact could get unpleasant during longer use on the lap. The inside, around the keyboard, only heats up marginally compared to idle mode. Criticism would be inappropriate here.Acer AS07A51 battery

Two stereo speakers for audio playback are located beside the display hinges. They supply a weak and unilateral sound. The trebles are reproduced well and the maximum volume is sufficient. There are no low pitches and basses, though. But this is basically not a drawback for an office laptop because external solutions can be used via the HDMI out or the 3.5mm stereo jack.Acer AS07A52 battery

6 cell, 48 Wh batteryThe older hardware isn't only noticed in performance, because the efficiency of the components has improved significantly with the launch of Intel's Sandy Bridge CPUs. We draw a comparison with the HP ProBook 4530s with an Intel Core i3-2310M including embedded graphics. Acer AS07A71 battery

The Dell Vostro 1540 with an Intel Core i3-370M consumes between 9 and 17.2 watts in idle mode. Thus, the laptop is on about the same level as current multimedia laptops with a significant performance plus. Acer AS07A72 battery

An example from this division would be the Medion Akoya P6631 notebook. The above mentioned comparison configuration consumes a maximum of 12.6 watts in office use, which results in a difference of 26.7 %.Acer AS07A75 battery

The rates of our test device and the HP notebook are equal during load (51.6 to 51.2 watts). However, we must point out the average is a lot lower in the newer ProBook and that it nevertheless bids a plus of performance. Acer AS09A61 battery

Although the Vostro 1540's hardware was state-of-the-art about a year ago, this power consumption is no longer acceptable and the majority of potential buyers will likely opt for the latest and not inevitably more expensive hardware.Acer BT.00603.036 battery
