Panasonic Toughbook FZ-55 MK1 Laptop Review

A tough cookie. The latest 14-inch Toughbook addresses many of the shortcomings of last year's model while retaining compatibility with all last generation accessories.

The Panasonic Toughbook 55 MK1 directly succeeds the last generation Toughbook 54 MK3 that we reviewed last year. It introduces a host of changes including new IP ratings and upgraded hardware while keeping the familiar chassis design mostly intact.

The list of gen-to-gen changes and supported features is enormous as detailed by Panasonic themselves through the official comparison tables below. For this review, we'll be checking out the core characteristics of the Toughbook 55 including its display, performance, and battery life. The system competes directly with other rugged laptops designed for industrial or outdoor environments including the Dell Latitude 7424 Rugged and Getac S410.

See the official Panasonic Toughbook 55 product page here for more information on pricing and features.

Case

Visually, the magnesium alloy chassis has not changed very much from the Tooughbook 54 as even their dimensions are nearly identical between them. Surfaces and hinges remain rigid and stronger than what you would find on any consumer laptop.

SD Card Reader

Unlike the older Toughbook 54 and its full-size SD reader, the Toughbook 55 uses a smaller and slower spring-loaded MicroSD reader instead. Panasonic says the slightly different dimensions of the new design were partly responsible for the omission of a full-size SD reader. Transfer rates are still good at about 80 MB/s with a UHS-II card.

Communication

The Intel 9560 module is an upgrade from the Intel 8265 on last year's model by providing both Wi-Fi 5 and Bluetooth 5 connectivity. Strangely, our unit could only connect to an 802.11n network as it is unable to establish a connection to our 802.11ac network. We've never experienced anything similar on other laptops with the same Intel 9560 module.

Maintenance

Servicing the SATA bay, M.2 slot, and batteries is easy as only a few latches need to be loosened. Accessing the RAM slots, however, will require a Philips screwdriver. Each SODIMM slots supports 32 GB modules for up to 64 GB maximum.

Accessories and Warranty

The system is compatible with all accessories designed for the Toughbook 54. A limited 3-year manufacturer warranty comes standard.

Input Devices

Keyboard

New to the Toughbook 55 is the removable keyboard that can be replaced if needed similar in vein to many ThinkPad laptops. The feel of the keys is otherwise quite similar to the Toughbook 54 including the relatively soft feedback in relation to most consumer and business laptops. It's too bad that the Arrow keys remain small and cramped.

An interesting note is that once the keyboard is removed, the keyboard must be discarded and replaced with a new one according to Panasonic.

Touchpad

The touchpad (8.5 x 4.5 cm) is slightly larger than the one on last year's Toughbook 54 (8 x 4 cm). Its surface is smooth when moving at medium to fast speeds with only minimal sticking when moving at slow speeds. Unlike on most Ultrabooks, the touchpad is very firm and not susceptible to any depressions or warping.

The dedicated mouse keys are shallow in travel and relatively weak in feedback despite the loud click.

Display

The Toughbook 55 uses an uncommon InfoVision M140NWF5 R3 IPS touchscreen panel. Very few laptops ship with InfoVision panels with one notable example being the Lenovo Yoga 530-14IKB and its InfoVision M140NWF5 R2 panel.

The most notable feature of the display is its super-bright backlight. Panasonic advertises a brightness of 1000 nits and we're able to confirm this with our own independent measurements. Drawbacks, however, include the slow black-white response times and limited color space that fortunately shouldn't impact the target industrial audience.

Perhaps the more notable drawbacks are the moderate-heavy uneven backlight bleeding, pulse-width modulation, and relatively grainy display as shown by our images and data below. The PWM of 694 Hz in particular is present on all brightness levels up to 99 percent which could potentially irritate users sensitive to onscreen flickering. Meanwhile, the grainy display is likely the consequence of having a thicker matte overlay for improved damage resistance.

Further measurements with an X-Rite colorimeter reveal generally inaccurate colors and an overly warm grayscale out of the box. Calibration addresses some of the shortcomings and improves grayscale significantly from an average DeltaE value of 5.5 to 2. Colors still become increasingly inaccurate at higher saturation levels due to the narrow gamut of the panel.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
29.6 ms ... rise ↗ and fall ↘ combined↗ 13.2 ms rise
↘ 16.4 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 71 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.9 ms).
       Response Time 50% Grey to 80% Grey
42 ms ... rise ↗ and fall ↘ combined↗ 20.8 ms rise
↘ 21.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 55 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (39.6 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 694.4 Hz ≤ 99 % brightness setting

The display backlight flickers at 694.4 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 694.4 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9270 (minimum: 43 - maximum: 142900) Hz was measured.

The 1000-nit backlight, matte overlay, 180-degree hinges, and wide IPS viewing angles contribute to the excellent outdoor visibility of the screen. Nonetheless, direct sunlight will still overwhelm the display and so we recommend working under shade if possible. Apparent contrast and colors degrade only if viewing from extreme angles.

Performance

LatencyMon
LatencyMon

The Intel U-class CPU targets low-power applications while the optional AMD Radeon Pro WX 4150 GPU should provide enough power to run more graphics-intensive applications involving video playback, recording, or very light CAD software. Running LatencyMon shows DPC latency issues even when the wireless is disabled which is unfortunate for a laptop targeting professionals.

The Core i5-8365U is performing where we expect it to be in relation to other laptops equipped with the same processor. Raw performance drops by only 7 percent when stressed for long periods as exemplified by our CineBench R15 Multi-Thread loop test below. Upgrading to the Core i7-8665U will bring up to 20 percent more CPU performance.

See our dedicated page on the Core i5-8365U for more technical information and benchmark comparisons.

Emissions

System Noise

Fan noise is quiet at the 29 to 30.5 dB(A) range when under low to medium loads. Extreme loads like Prime95 will cause the fan to pulse to 39 dB(A) momentarily before falling and stabilizing at 33.4 dB(A). Perhaps not surprisingly, these results are similar to what we recorded on last year's Toughbook 54 as shown by our comparison table below. Fan noise is audible but also easy to ignore.

We suspect that the SKU with dedicated AMD Radeon graphics will be louder than what we've recorded here since the discrete GPU produces more heat and is more demanding than the Intel U-class CPU.

We can notice very slight electronic noise or coil whine when placing an ear near the keyboard keys. It's thankfully minor enough to not be a cause for concern.

Surface temperatures are generally warmer on the right half of the notebook than the left half since most of the motherboard components are concentrated on this side of the system. At worst, we're able to record a surface temperature of 38 C on areas that are thankfully away from the keyboard keys and palm rests.

Speakers

Panasonic advertises 92 dB stereo speakers while our own independent microphone measurements show a maximum volume of 84 dB when standing 15 cm away from the front of the laptop. Roll off begins at around 1000 Hz compared to 250 Hz or 500 Hz on most Ultrabooks to represent poor bass reproduction on the Toughbook. We can notice no static or vibration issues when on high volume settings which are perhaps more important qualities of a rugged industrial laptop.

Energy Management

Power Consumption

Idling on desktop consumes between 3 W and 11 W depending on the brightness setting and power profile. Jumping from minimum brightness to maximum brightness will increase consumption by about 6 to 7 W. We're able to record a maximum consumption of 72 W from the small-medium (~14 x 5.3 x 3 cm) 110 W AC adapter. Consumption eventually falls and stabilizes at about 38 W when under such extreme processing stress due to thermal limitations.

Small-medium sized AC adapter

Runtimes are very long with the primary battery at over 18 hours of real-world use when looping a web page every 40 seconds. Users can swap or add a secondary battery for even longer runtimes if needed.

Recharging takes approximately 1.5 hours not unlike most Ultrabooks. We attempted to recharge the system via a 130 W USB Type-C AC adapter, but it would not work. USB Type-C with Power Delivery is an option not included on our unit.

Verdict

In review: Panasonic Toughbook 55 MK1. Test model provided by Panasonic
In review: Panasonic Toughbook 55 MK1. Test model provided by Panasonic

The Toughbook 55 offers 70 percent faster CPU performance than the Toughbook 54 while being backwards compatible with all of its accessories. Battery life is also extraordinarily long at 18 hours of constant WLAN use and the serviceable batteries, M.2 drives, WAN, and SATA expansion all make this a versatile machine when on the field.

There are aspects we think could be better. The slower MicroSD reader is a downgrade from the last generation model and the small Arrow keys are too cramped. Some features that are otherwise standard on most Ultrabooks are optional on the Toughbook including USB Type-C PD and a fingerprint reader. Other features are completely missing like Thunderbolt 3, 4K UHD, and NFC. Furthermore, the bright display could be less grainy with deeper colors, no PWM, and reduced uneven backlight bleeding for a better visual experience.

You'll want the Toughbook 55 for its longevity, bright display, wide range of accessories, and ease of servicing. Just don't expect the best colors or performance as processor options are limited to the Intel U class family with an optional three-year old Radeon GPU.

Allen Ngo - US Editor in Chief
After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
