MagyarAcer TravelMate P648-G2 (i7, 256 GB) Laptop Review
For the original German review see here
Acer calls its TravelMate P6 lineup top of the line performance, light, and durable. The TravelMate P648-M-757N already confirmed these traits in the previous test. The TravelMate P648 G2 M 7619 successor has a better configuration than its predecessor and has to compete against Lenovo's ThinkPad X1 Carbon, Dell's Latitude 14 E5470, and Toshiba's Tecra Z50-C-10P in the test.
Originally, the device was reviewed by our German staff. The model name is TravelMate P648-G2-M-73T0, and it costs 1500 Euros (~$1700). The same model is available in the UK as P648 G2 M 7619. Retailers sell it for about £1800 (~$2307) at the time of writing.
Case
The casing's design has been completely adopted. A high-quality while basic device awaits the buyer. Carbon-fiber reinforced plastic and aluminum convey stability. Particularly favorable: Fingerprints hardly remain on the matte-black surface. All parts of the casing have been manufactured and assembled impeccably. The lid's metal hinges keep the display firmly in the opened position.
A micro-SIM card slot, a port for Acer's ProDock docking station and speakers are on the casing's underside. The hard drive and working memory could be replaced or expanded via a screw-fastened hatch. The battery can only be accessed by removing the entire base plate.
Connectivity
The interface diversity of Acer's TravelMate P648 G2 M 7619 is very solid. Most ports are situated on the casing's left. Thus, right-handed users will not have problems with cables that unnecessarily obstruct the space needed for using an external mouse. Two widely distributed connections for monitors and projectors are present in the forms of VGA and HDMI. Furthermore, Gigabit Ethernet, USB 3.0, Thunderbolt ports, and a combo-audio jack are on the device's left. Two more USB 3.0 ports, a Kensington lock, and power-in are situated on the left. The SD-card reader is on the laptop's front.
Acer offers an optional docking station that provides additional interfaces (e.g. DVI, SATA) and several USB ports.
SD-card reader
The SD-card reader is situated on the front of Acer's TravelMate P648 G2 M 7619. The card slot has a plastic dummy that prevents dust from infiltrating the port. We adversely noticed that the dummy has to be pressed quite deeply to release the lock mechanism. The resistance is also very high, making it unnecessarily difficult to insert and remove an SD card. The SD-card reader achieved a maximum read speed of 87.3 MB/s with our Toshiba Exceria Pro SDXC 64 GB UHS-II reference card. This rate is well on par with most review samples. The average copy speed of 77.8 MB/s is also competitive.

Communication
Our review sample is furnished with Wi-Fi, Bluetooth, and an LTE module. Intel's dual-band Wireless-AC 7265 provides a good Wi-Fi signal even with two concrete walls between the router and laptop. In addition to all former standards, it supports the fast 802.11 ac standard, as well as Bluetooth 4.0.
The installed Huawei ME936 mobile network module allows using mobile Internet at speeds of up to 100 MBit/s. When LTE is not available, UMTS, HSPA and the even slower EDGE, GPRS, and GSM standards are supported.

Security
Acer equips the TravelMate P648 G2 M 7619 with TPM 2.0 and a fingerprint scanner. A cable lock can be connected to the corresponding slot for securing the laptop physically. Acer's own ProShield security software is preloaded on our review sample. According to Acer, it protects the laptop from unauthorized access and also protects the data on the local storage device. The user has to assign a TPM and ProShield password, and register a fingerprint to use the program. A trial version of Norton Security is also preloaded.
Accessories
Acer offers the ProDock 3 docking station for expanding the interface options of the TravelMate P648 G2 M 7619. The ProDock has HDMI, DVI, VGA, and DisplayPort (one each) for video output. In addition to Gigabit LAN and four USB 3.0 ports, the dock also provides dedicated headphone and microphone jacks. It costs approximately 180 Euros (~$204). An additional power supply is included.
Maintenance
It is possible to access the additional hard drive and an empty memory bank via a maintenance hatch. The installed 8 GB working memory is soldered. The other hardware components can be accessed by removing the base plate, which is easy to remove after releasing 15 more screws. This then allows replacing the battery or cleaning the fan. The CPU is also soldered.
Warranty
The manufacturer's three-year warranty includes a pick-up and return service. Acer also provides technical hardware support for three years. Software support is limited to just 180 days. Please see our Guarantees, Return policies and Warranties FAQ for country-specific information.
Input Devices
Keyboard
The keyboard is suitable for prolonged typing sessions. Although the pressure point only offers low resistance, it is well-palpable. A short drop allows easy typing as soon as the user has gotten used to it. The "larger" keys, such as return or space, are also comfortable to use and they do not clatter. The keyboard is backlit for working in the dark. Its brightness cannot be adapted.
Touchpad
The touchpad has a sleek surface that even allows using it with moist fingers very well. The fingers glide pleasantly over the pad. Multi-gesture control is also supported. The fingerprint scanner is situated between the left and right mouse keys. In contrast to the keyboard, the keys have to be pressed strongly for triggering a click.
Display
Acer installs a matte IPS panel with a resolution of 1920x1080 pixels into the TravelMate P648 G2 M 7619. The screen is sufficiently bright and recognizing content is just possible even outside of shaded areas outdoors. However, the brightness of 253 cd/m² is low compared with the competitors. The contrast of 1100:1 is in a solid midfield. We did not ascertain PWM-flickering.

* ... smaller is better
Subjectively, the screen in the TravelMate P648 G2 M 7619 delivers a pleasing image. The colors look good and a grayish tint is not visible. The measurements confirm this impression. The black level is relatively low (0.24 cd/m²) and the sRGB color space can be reproduced by up to 91%. The AdobeRGB color space is displayed by up to 59%.
The screen's brightness is high enough for outdoor use. However, the shade should be preferred since looking at the screen's content under direct sunlight becomes strenuous in the long run. The anti-glare surface definitely contributes to legibility. The viewing angle is stable from all directions.

Performance
Acer delivers the TravelMate P648 G2 M 7619 with 8 GB of working memory and Intel's Core i7-7500U CPU with an integrated HD Graphics 620 graphics card. When required, more working memory and a larger HDD can be installed. Our review sample carries an SSD with a storage capacity of 256 GB as the system drive and a 1 TB HDD for storing data.
Processor
Intel's Core i7-7500U processor in the review sample has been made for laptops and ultrabooks. Its two cores can process four threads at the same time thanks to Hyper-Threading. Acer states a clock speed of 2.7 GHz but as much as 3.5 GHz is possible via the dual-core Turbo. The clock remained stable throughout the 30-minute Cinebench R15 Multi benchmark test. The full performance can be retrieved even in battery mode when using the corresponding energy-saving settings.
Compared with Lenovo's ThinkPad X1 Carbon that is also based on Intel's Core i7-7500U, it becomes obvious that the clock speed of the TravelMate P648 G2 M 7619 does not throttle. The reason for this is presumably the fact that Acer clocks the CPU at around 2.9 GHz so that it can operate smoothly and without temperature-related performance losses. Although the X1 Carbon begins the CB15 Multi benchmark at a higher score, temperatures causes it to throttle after a while. Ultimately, less performance can be retrieved permanently than from the TravelMate P648 G2 M 7619.
System Performance
The PCMark 8 test proves that Acer has once again provided a business laptop that is well-placed in our top 10 list. The Home and Work test outcomes remove Dell's Latitude 14 E5470 from third place. The TravelMate P648 G2 M 7619 is very pleasant to work with in everyday use. Programs launch in a flash thanks to the SSD, and everything else also runs smoothly. We did not encounter any issues in working routine.

Storage Devices
Acer installs a solid SSD that can keep up with present competitors in terms of speed. Neither the CrystalDiskMark 3.0 nor AS SSD benchmark rates promise an above average nor a below average performance. It is only striking that the times for the dISO, program and game copy test are lower than, for example, Dell's Latitude 14 E5470 despite the slightly higher write and read rates in AS SSD and CrystalDiskMark by comparison.

Graphics Card
Being a business laptop with an integrated Intel HD Graphics 620, the TravelMate P648 G2 M 7619 has not been designed for graphics-driven applications. The available performance is enough for playing high-resolution videos. Efficient video-editing with applications that support Intel's Quick Sync technology is also possible. The graphics card's performance remains stable even in battery mode.
The processor's predefined performance range has an impact on the clock speed of Intel's HD Graphics 620. This is the reason that the 3DMark 11 benchmark rate is lower than that of Lenovo's ThinkPad X1 Carbon 2017 despite the same i7-7500U CPU and HD Graphics 620. While the ThinkPad clocks at its full Turbo speed of 3.5 GHz that also allows the HD Graphics 620 to retrieve its full performance, Acer's TravelMate apparently clocks stably at 2.9 GHz. Thus, the graphics card's performance is slightly lower. In contrast to the ThinkPad, the TravelMate's performance does not throttle due to increased temperatures.

Gaming Performance
It should not be surprising that the performance in the field of gaming is not good. Older games or games with low requirements on the graphics card are still rendered smoothly in minimum settings. As soon as features such as anti-aliasing, V-Sync or anisotropic-filtering are enabled, most games become unplayable. Our gaming list provides an insight into which games can be played on Intel's HD Graphics 620.

Emissions
System Noise
The TravelMate P648 G2 M 7619 was very quiet in the practical test. The fan noise only increased during the benchmarks in the test period. Unfavorably noticed: Rather than increasing the speed consistently, the fan spun irregularly. The resulting, permanently changing noise level was somewhat unpleasant in the long run.

Temperature
The TravelMate P648 G2 M 7619 remained pleasantly cool in office routine. The wrist rest subjectively always stayed cold. The laptop's surface did not get too hot even on very warm days. The temperature measurements confirm this impression. 40 °C is not reached even during load.
The hot spots are measured in the keyboard center and toward the monitor on the left. The CPU and fan are underneath these points. Although the CPU reached up to 75 °C during the stress test, the surface temperatures stay moderate. The device can still be used on the lap even during full load.
The CPU cores reached the Turbo speed of 3.5 GHz for a short time in the stress test. The mean of the clock speed in the one-hour stress simulation was approximately 2.9 GHz. Again, it may be presumed that Acer clocks the CPU at 2.9 GHz (as Cinebench illustrates) to prevent performance losses during permanent load. Throttling was not ascertained and a 3DMark test directly after the stress period only presented marginally lower rates than in the test before during normal use. Restrictions should not be experienced in everyday use.
(+) The maximum temperature on the upper side is 39.1 °C / 102 F, compared to the average of 34.3 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
(+) The bottom heats up to a maximum of 35 °C / 95 F, compared to the average of 36.7 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 26 °C / 79 F, compared to the device average of 29.5 °C / 85 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 28.1 °C / 82.6 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 27.7 °C / 81.9 F (-0.4 °C / -0.7 F).
Speakers
Acer has installed the speakers of the TravelMate P648 G2 M 7619 on the underside. The sound is not breathtaking, but it is not so bad that everything has to be muted right away, either. It is quite possible to listen to music at medium volume if basses are not expected and the user can live with the slightly piercing trebles. Speech is intelligible, but headphones (or external speakers) should be preferred over the installed speakers.
The integrated combo-audio jack detects when a device has been connected and opens a popup window. Here, the user can select whether a headset or a headphone has been connected. The software switches the port according to the selected device automatically.

Energy Management
Power Consumption
Acer includes a 65-watt power supply for the TravelMate P648 G2 M 7619. A glance at the stress test shows why the power supply has almost twice the performance compared with the maximum load consumption rate measured. When adding five watts maximum for each of the two storage devices, the power supply's reserves are not very big after all. Nevertheless, a performance scenario like in our stress test will likely be an exception and the power supply's capacity is high enough to power the device.
The differences to the competitors are slight in the category comparison. Five watts more or less can be neglected in AC mode.

Battery Runtime
The battery in Acer's TravelMate P648 G2 M 7619 lasted for over 18 hours in the Battery Eater Reader's test. It was almost 2 hours during maximum load. To determine a practical rate, we simulate browsing with the laptop via our Wi-Fi script. The review sample switched to standby after 11 hours and 12 minutes at a screen brightness of 50% and enabled "Balanced" energy profile.
The battery performance is good compared with the competition. Acer places itself among comparable devices and delivers a laptop that can last a long workday even without its power supply. However, since the battery is identical to the ones in the predecessors, an improved battery life cannot be ascertained compared with the TravelMate P648-M-757N and P645-S.

Verdict
Pros
Cons
The TravelMate P648 G2 M 7619 is a light and durable laptop. All needs for a workday should be covered with an updated Kaby Lake CPU, faster SSD, and bigger HDD. The display is bright enough to still be able to work even in unfavorable light conditions. Acer offers a matching docking station for expanding the interface options. The keyboard could be a bit crisper and Acer could have also gladly left out the pulsating fan settings.
Acer once again updates its TravelMate P6 Series. However, not much has changed apart from the modern Kaby Lake CPU and expanded hard drive storage.
The TravelMate P648 G2 M 7619 can be highly recommended to business users looking for an alternative to Lenovo, Dell, and HP. Our review sample is available for approximately 1500 Euros (~$1700).
