HP's ProBook 450 series includes 15.6-inch office laptops for both individual and professional customers with various models and configuration options such as Probook 450 G0, Probook 450 G1. In this article we will evaluate the HP ProBook 450 G1 to see if it leaves a good impression on users like other brothers in the same line.
Basically, the Probook 450 laptops have the same design and quality of assembly, they are just different from the hardware configuration. Some readers have sent a request to evaluate this product line, but due to no conditions to directly experience the product, VnReview translates from the review of the page. Notebook Check, readers can consult when choosing to buy this laptop.
Laptops used for comparison, compared to the Lenovo ThinkPad Edge E450 (Core i3-4000M, HD Graphics 4600) and Acer TravelMate P445-M (Core i5-4200U, HD Graphics 4400).
The HP ProBook 450 G1 also has a brushed aluminum lid like its siblings. The frame around the matte screen looks good. However, the location of the slots and connectors of the ProBook 450 do not convince them to be placed on either side of the flank rather than on the front edge of the machine.
However, we appreciate the maintenance casing at the bottom of the laptop. It can be easily removed after removing the battery without using a screwdriver. And after removing this cover, you can access almost all components inside the machine.
The ProBook 450's connections are not necessarily missing but not rich. It has only two USB 2.0 ports and two USB 3.0 ports, HDMI, VGA and Gigabit LAN ports. Although there are enough ports to connect, but according to our location they should be improved.
USB ports and 3.5mm headphone jacks are located on the right side of the device. USB 3.0, LAN, VGA and HDMI ports are crowded together on the left flank just before the heat sink slot. Left-handed people will not have a mouse connection if a monitor and a peripheral device are connected to the USB port. In addition, the distance between USB ports is quite narrow, which can make it difficult to plug in a USB device if the device has a large shape (such as a 3G USB device). SD card reader is located on the front edge of the device.
The ProBook 450 removed the ExpressCard but retained the Kensington lock. There is no dedicated dock connector, but users can purchase a USB dock. Fingerprint scanner is still in a convenient position right at the right hand rest. Users who do not want to type in a password can open the device with their fingerprints.
HP uses RaLink's WiFi module, which supports the 802.11 b / g / n standard with a maximum speed of 300Mbps. The RaLink RA3290 module only works in the 2.4GHz band so it does not support the 5GHz band. In return it integrates all the features of Bluetooth 4.0. WiFi transmission rate is acceptable.
On the network, HP will support customers to connect to the Internet via Gigabit LAN. There is nothing unusual with this connection port. The transmission speed of the wire network meets the standard Gigabit LAN standard.
In addition to the Kensington lock, the ProBook 450 also has a fingerprint scanner. It allows users to boot the device with one of their fingers. Theoretically, fingerprints can replace all types of passwords. However, consumers do not rely too much on this technology because so many hackers can easily overcome fingerprint scanners. Network security company Bkav once demonstrated the lack of security of this fingerprint unlock technology.
Although the ProBook 450 does not have a TPM, the BIOS can be password protected. This cannot stop hackers but can make them more time consuming. However, dodgy hackers can easily access the BIOS battery after removing the easy-to-open cover plate at the bottom of the machine.
HP's DriveGuard feature is very useful. This software monitors the acceleration of the integrated hard drive and fixes the hard drive's read / write head when a shock is detected. This reduces the risk of data loss when the laptop is moved or dropped during use.
There are not many accessories available or optional that come with the ProBook 450. For example, there is no dock option or high capacity battery. But luckily, this laptop is provided with a DVD driver, application and Windows 8 Pro with manuals, battery and charger.
The large maintenance case at the bottom of the laptop can be removed easily after removing the battery without using a screwdriver. Although the cover is fit, tight and safe without screws, you can choose the safety maintenance cover fixed by screws.
After removing the maintenance cover, we can access the hard drive and radiator fan, BIOS battery, WiFi module and hard drive. An empty slot allows the addition of a mSATA SSD directly placed next to the WiFi module in order to speed up the laptop with a few simple steps.
The HP ProBook 450 is backed by a 12-month warranty. You can pay to buy more warranty time. To upgrade the warranty period to 36 months you have to spend up to 320 USD (equivalent to 6.8 million).
The ProBook 450 G1 E9Y58EA has an Intel Core i7-4720MQ processor clocked at 2.2GHz, the mainbroad Intel HM87, 8GB of single channel DDR3 RAM, integrated Intel HD Graphics 4600 graphics. Its LED display is 15.6 inches in size. , resolution of 1366×768 pixels. Seagate Momentus drive ST750LM022 HN-M750MB, 750GB capacity 5400 rpm, 650GB available.
It measures 29 x 375 x 256 mm, weighing 2.37 kg. 47Wh, 10.8V, 4200mAh Lithium-Ion batteries. Microsoft Windows 7 Professional operating system (64 Bit) plus Windows 8 Pro installation DVD (64 Bit). Other extra features include HD Webcam (1280×720 pixels), stereo speakers, chiclet keyboard without backlight. Included software includes: Cyberlink Power2Go 8, Cyberlink PowerDVD 12, Cyberlink YouCam, HP Client Security Manager, HP Drive Encryption, Microsoft Office 365 (trial), PDF Complete (Corporate Edition), Skype.
Keyboard and Touchpad
One of the highlights of the ProBook 450 is the chiclet style keyboard of good quality. All keys have enough space, have normal size and layout. HP still tries to equip the standard-sized numeric keypad for the ProBook 450 and only slightly reduces the navigation keys.
The typing experience is very pleasant even for a long time. The keyboard provides users with appropriate key settlement and slight bounce. The keyboard is slightly soft in the DVD drive area, in this area the key's bounce is also higher than other areas.
The rough surface touchpad of the ProBook 450 is standard in size and slightly shifted to the left, not in the center of the palm rest. Good fingers on the touchpad are quite good, not too fast and quite accurate. Use it quite comfortably for daily work.
ProBook's matte screen has a resolution of 1366×768 pixels. The average brightness of the screen is 202.8 cd / m2, the average compared to comparison laptops. TravelMate is on par with 200,6 cd / m2 brightness and ThinkPad Edge is slightly better with 217.2 cd / m2 brightness.
The contrast of the screen reaches 211: 1 and the black level is 1.08 cd / m2, the numbers are not impressive. Nobody wants to see these scores on a laptop screen today and don't want to see them on a laptop screen for 23 million dong. However, TravelMate's scores (361: 1, 0.54 cd / m2) and ThinkPad Edge (289: 1, 0.89 cd / m2) are also unimpressive. The ProBook screen cannot reproduce AdobeRGB and sRGB color space. It covered 50.2% of color space on sRGB and 34.8% on AdobeRGB.
Modify the screen's DeltaE on the default state to 12.64. No color reaches DeltaE less than 3. The screen is also slightly blue, which can be removed by adjusting the screen.
Although the brightness is only average, ProBook can be used outdoors. The matte screen is useful in this case. However, avoid places with too high ambient light.
The ProBook 450 G1's viewing angle is quite stable on par with the ProBook 450 G0 and ProBook 455. Changing the perspective quickly and vertically will cause the image to be deformed. Horizontal viewing angles may appear wider and the content may still be recognizable when viewed from the flanks but it will become blurry as the angle increases.
Laptop models rated in the article cost about 790 EUR (equivalent to 23.2 million) in Germany, but users can configure options to reduce prices. In Vietnam, the machine has many different configuration options for the price of VND 15 million.
The ProBook 450 G1 in this review owns an Intel Haswell Core i7-4720MQ quad-core processor with clock speed of 2.2GHz, can be overclocked to 2.9GHz (all four cores), 3.1GHz (two core), and 3.2GHz (one core) via Turbo. Intel confirmed the CPU's TDP of 37 watts.
This microprocessor performed the Cinebench CPU test at the highest speed, giving good scores. Both ThinkPad Edge laptops (Core i3-4000M, HD Graphics 4600) and TravelMate (Core i5-4200U, HD Graphics 4400) cannot compete with ProBook because they have weaker processors.
The system runs smoothly, without any delays or errors. PCMark benchmark score is also very impressive. TravelMate and ThinkPad Edge are lagging behind because of weaker processors.
HP equips the ProBook 450 G1 series with Seagate's Momentus hard drive. It has a capacity of 750GB and a rotation speed of 5400rpm. CrystalDiskMark recorded a reading speed of 103.3 MB / s and HD Tune calculated the data transfer rate of 82.4 MB / s. These are impressive results with a 5400rpm hard drive.
Although this hard drive has a good speed, it doesn't quite fit the price of this laptop. HP needs to add, at least, a 7200rpm hard drive, or a hybrid hard drive or high-end drive rather than a small-capacity SSD.
Intel's HD Graphics 4600 integrated graphics card on the ProBook is responsible for video output. It supports DirectX 11.1 and has a clock speed between 200 and 1150MHz, helping the Probook overcome ThinkPad Edge to lead in 3DMark testing despite having the same graphics card. The reason is that ProBook has a slightly higher clock rate and HP's laptop also benefits from its powerful CPU. TravelMate ranks last due to the weakest graphics card.
ProBook hardware is capable of softly handling almost all current games at low resolution and quality. For games that require moderate hardware, you can set higher resolution and image quality, such as StarCraft II. Frame rate can be increased slightly. HP laptops will work in channel mode sometimes equipped with an extra RAM. This will help to better GPU utilization and provide higher frame rates. The average increase is up to 20%.
Consumers who regularly play games can choose the ProBook model which is equipped with Radeon HD 8750M discrete graphics card. Or choose an alternative laptop, such as the Dell Latitude 3540 with a discrete Radeon HD 8850M graphics card.
Noise generated in sleep mode is within the limit. The drive only makes noise when you access the information. Although the radiator fan runs continuously, we only hear its noise in a really quiet environment. The fan will accelerate when the machine has to handle heavy tasks but the noise is still acceptable. TravelMate runs quite smoothly but this is not a surprise because it owns ULV power-saving processor. ThinkPad Edge is also quieter, but Lenovo's laptop works with less than two processors compared to the ProBook.
All three laptops are not too hot in idle mode. Temperature is within acceptable ranges at all times of measurement. Only the ProBook heats up a bit when handling heavy tasks. It reaches 50 degrees C in the area of the fan. The temperature of both ThinkPad Edge and TravelMate stays below 40 degrees Celsius at all times.
ProBook temperature in idle mode …
… and when handling heavy tasks
Power consumption capacity
The ProBook's power consumption in idle mode varies widely, from 6.3 to 8.8 watts, proving it is very power efficient despite owning a high-performance quad-core processor. ThinkPad Edge (5.4 to 7.9 watts) is a bit more power-efficient and the TravelMate (4.3 to 12.7 watts) consumes more power. This is surprising because TravelMate is equipped with a ULV power-saving processor. ProBook requires higher power level, 41.6 watts when downloading mid-range applications and 58.2 watts when loading heavy applications.
ProBook 450 G1 power consumption
In terms of battery life, despite owning a standard mobile processor (not a power saver), ProBook has a very good battery life. ProBook batteries can provide power to operate the device for 9 hours 39 minutes in idle mode. TravelMate stopped first at 8 hours 13 minutes. This test is not done with ThinkPad Edge. The idle mode is set to the screen brightness to a minimum, the power saving setting is enabled, and the wireless connection module is turned off. ProBook can run 59 minutes when running full load. TravelMate is on par with reaching 1 hour 5 minutes, and ThinkPad Edge looks better when it reaches 1 hour 31 minutes. The laptops in this test operate with maximum screen brightness, high-performance power settings are enabled and the wireless connection module is turned on.
ProBook 450 G1 battery life
In Web browsing with WiFi, ProBook stopped at 4 hours 48 minutes, a little longer than TravelMate's 4 hours and 30 minutes and 4 hours 23 minutes of ThinkPad Edge. The settings in this mode include the energy saving mode enabled, the screen brightness is kept at 150cd / m2 and the website is automatically opened every 40 seconds. The ProBook stopped operating after 3 hours 10 minutes of DVD playback, lower than TravelMate's 3 hours 34 minutes and higher than ThinkPad Edge's 3 hours 3 minutes. The DVD playback test is performed under the condition that the energy saving mode is activated (or set higher to make sure the DVD works smoothly), the maximum screen brightness and wireless connection module are disable.
HP ProBook 450 G1 E9Y58EA provides high application performance and smooth operation. Its battery life is also very good. HP also has good data entry devices for ProBook. In addition, the convenience of the maintenance shell is a plus for the machine. However, HP has reduced the value of this laptop by equipping it with an unacceptable screen. It is slightly greenish, low contrast and medium brightness. A computer for more than VND 20 million needs to be more than that. One year warranty is also too short. Users who do not need a powerful Core i7 processor can choose the ProBook with a Core i3-4000M processor that will save about VND 5 million.
Lenovo ThinkPad Edge E540 stands out with good quality data entry devices, and its price is also more reasonable. The 20C60043GE model owns a Core i5-4200M processor that costs about VND15 million but does not include the Windows operating system. The Acer TravelMate P455-M scores with a full HD resolution open screen and is always smooth when operating.
