Lenovo Legion 5i (2020) review: the jack-of-all-trades and master of them all?

[ntab Configuration]

Lenovo legion 5i banner

Last year, the Lenovo Legion Y540 gaming laptop enjoyed noticeable market success both in terms of sales and user feedback. Building upon that success, this year, Lenovo released the new Legion line of gaming laptops, with the Legion 5 being the direct successor of the Y540.

At first glance, it seems that the 2020 Legion 5 inherits all of the beloved traits of the Y540 – a compact gaming laptop with excellent thermals and performance. However, it appears that Lenovo did make some improvements which overall may make this laptop perfect for both gamers and non-gamers.

The machine can be fitted with both AMD’s Ryzen and Intel’s latest 10th gen processors, GTX or RTX Nvidia dedicated graphics cards and various display options, ranging from a modest 60 Hz refresh rate panel, all the way up to high-end, colour accurate, 240 Hz display. The base version of the Legion 5 starts at $999, but it often goes on sale for a lot less than that. A fully upgraded Lenovo Legion 5 can easily surpass $1600.

Since 2020, Lenovo decided to rebrand all of its gaming laptops to more “user-friendly” names and split them into three categories: Gaming 3, Gaming 5 and Gaming 7. Gaming 3 is for low budget gamers, Gaming 5 is sort-of middle tier, and Gaming 7 is high-end. Before this, Lenovo used to split its gaming laptops into Ideapad Gaming now Gaming 3, Legion Y5x0 and Legion Y7x0 series. The BIOS of the Legion 5 still bears the name Y550-IMH, indicating that initially, this laptop was supposed to be called Legion Y550, a direct successor to the Y540.

There are two versions: Legion 5 (for AMD variants) and Legion 5i (for Intel variants). This review is for the Legion 5i.

On the exterior, the Lenovo 5i looks nothing like a gaming laptop. In fact, with its Phantom Black paint, it has a very mature/clean look, which resembles a ThinkPad – Lenovo’s business-grade lineup. Instead of last year’s backlit logo, the display lid now features an iridescent “Legion” logo on its top-left part, and a subtle metal plate with “Lenovo” written on it, on the bottom right side. Although the chassis is made entirely out of ABS plastic, it feels very sturdy and gives a “premium vibe”. Both the keyboard deck and the back of the lid feature a soft rubberised touch surface, and while it does not make them fingerprint-proof, it does help to prevent the attachment of smudges and fingerprints to an extent. The display lid can be opened with one hand at a wide 180 degrees angle, but this operation needs to be done gently since at first, the display lid will lift the entire chassis, and then it slowly releases the bottom of the laptop.

Note:
The hinge problems reported on the more expensive Legion 7, are non-existent on the Legion 5. The Legion 7 hinge metal plate is glued to the body of the laptop, while on the Legion 5, the hinges are fixed using metal reinforcement riveted to the body.

From all the gaming laptops tested so far, the Legion 5i by far has the best keyboard. Without exaggeration, typing on the Legion 5 feels a lot like typing on a ThinkPad, and it is indeed an excellent typing experience. The advertised 1.5 mm travel time feels just right, the concave keycaps are very comfortable, have great feedback to them and the keys do not feel cramped at all. The keyboard features a full-sized Numpad, and while its keys are a little bit smaller than the rest of the keyboard, at least it offers a clean, classic layout instead of a merged/mashed arrow-Numpad layout such as it is the case with other gaming laptops. Speaking of the arrow keys, they seem a little bit bigger and separated from the rest of the keyboard, which is a smart design to avoid accidental key-presses while gaming.

The keyboard also supports n-key rollover, a feature usually reserved for much more expensive laptops. Rollover is the ability of a computer keyboard to handle several simultaneous keystrokes correctly.

The keyboard is also white backlit with two intensity levels that can be switched between by pressing Fn + Space keys. There are also light indicators for Caps Lock, Num Lock, and Fn Lock. As a side note, it is worth mentioning that the laptop can be purchased with a four zones RGB keyboard for an extra ~$30 on Lenovo’s official store.

The touchpad uses Windows Precision drivers, and it has no dedicated left and right buttons. The surface area is average in size, and it is made out of plastic. The touchpad feels firm when clicking and seems to be accurate even in its corners. While the touchpad does not impress in any way, it is worth mentioning that it is not as bad as in other gaming laptops tested so far. Even though most gamers will invest in a mouse anyway, it is still a decent touchpad for those who will use the laptop in classrooms or at work.

Thankfully, Lenovo listened to its customers and moved the camera from the bottom of the display to a more normal position above the screen. That is right! No more double-chins. And as a bonus, Lenovo also added a Privacy shutter, which usually is reserved for its more expensive business lineups. As for the camera itself, it’s the usual HD camera found on most gaming laptops. It records in 720p at 30 frames per second, and it is OK overall, but the pictures tend to lose a lot of details in low light conditions. Fortunately, the user can somewhat alleviate that problem using the Lenovo Vantage app, where it can tinker with some of the camera settings, like brightness, contrast and exposure.

The microphone array does a great job. All recordings sounded clear without picking any noticeable background noise.

[ntab Disassembly]

Lenovo Legion 5i bottom panel
Lenovo Legion 5i bottom panel

There are eleven Philips head screws on the back of the laptop that need unscrewing. After that, starting from the front, carefully place a prying tool or a plastic card in the space between the plastic bottom cover and the main chassis, then move the prying tool or plastic card all along this separation space. As the prying tool/plastic card moves along this space, it will slowly un-clip the bottom cover from the main chassis. Finally, lift the bottom lid to reveal the laptop’s internal components. When lifting the cover, pay extra attention to the back of the laptop. Most of the peripheral ports are situated there and lifting the cover without being extra careful may damage the ports or the chassis.

WARNING: Disassembly is not as easy as with other laptops. The clips that hold the backplate need to be forced a little to unclip themselves. Also, it is not possible to move the prying tool/plastic card on the sides of the laptop to unclip it, which again means extra force needs to be applied from the front unclipped area for the backplate to come out.

To avoid applying extra force and potentially damaging the laptop, you need a second, thin prying tool/plastic card to unclip the sides of the laptop easily. One prying tool needs to be in the middle of separation space between the main chassis and the exhaust vent and another one right under the USB port, just like in the picture below. Using the two prying tools/cards together, gently push the main chassis away from the part with the exhaust vents. This manoeuvre should unclip the sides of the laptop without using a lot of force.

Inside, there is:

  • two M.2 SSD/PCIe slots;
  • two RAM slots;
  • a PCIe slot for the Wi-Fi card;
  • (If the laptop has a 60 WHr battery, then one 1 X M.2 SSD slot is replaced by a 1 X 2.5-inch SATA slot.)

Please note that not all Legion 5 models come with an 80 WHr battery. Some of them come with a smaller 60 Whr battery. The ones with the smaller battery have room for an additional 2.5-inch drive, while those with the 80 WHr battery, like the Legion 5 15IMH05 reviewed here, trade the storage bay for the larger battery and only get two M.2 slots. Also, the 2.5-inch drive seems to block the second M.2 slot for some reason.

[ntab Ports]

There is a wide variety of ports on the Legion 5i, most of them located at the back of the laptop. From an ergonomic perspective, this is an excellent port arrangement. If only more laptop manufacturers would follow this trend. To be clear, having most ports at the back of the laptop, prevents cables and other connected peripherals from interfering with the laptop’s cooling and mouse usage. Still, Lenovo left one USB Type-A port on each side of the machine for quick access, alongside a 3.5 mm jack. Also, Lenovo decided to replace last year’s mini DisplayPort with a USB Type-A port, and this is an OK change since the USB Type-C port can also act as a mini DP port.

Overall, the laptop has :

  • one Ethernet extension connector;
  • four USB 3.0 Type-A ports;
  • one USB 3.0 Type-C port (also known as USB-C 3.2 Gen 1);
  • one HDMI 2.0 port;
  • a standard 3.5mm jack combo for microphone and headphones or speakers;
  • one Kensington lock
  • a DC-in power connector.

Another thing worth mentioning is that one of the USB Type-A ports has its charging capabilities always-on (even if the laptop is powered off). This feature came in useful when, during the laptop’s testing, there was a day-long blackout, and the laptop acted like a huge power bank for all of our phones. This option can be turned off from the Lenovo Vantage app.


[ntab Display]

Lenovo Legion 5i display

The display on this review unit is called BOE0900/NV156FHM-N6A, which is a Full HD, IPS panel. It has a 60 Hz refresh rate, great viewing angles and, with its measured 328 nits, it provides decent outdoor visibility, though it is still preferable to use it in the shade. It also did not suffer from any backlight bleeding.

The Legion 5i can be configured with three other display options with different refresh rates: 120 Hz, 144 Hz and respectively 240 Hz. The 120 Hz panel is the worst of them all, with washed-out colours and low brightness, ruining an otherwise excellent machine. If possible, get the 60 Hz panel instead since the GTX 1650 Ti cannot push more than 60 fps on High to Ultra settings in most modern games anyway. Also, the 60 Hz panel has better colour coverage at 94.7% sRGB, 68.8% Adobe RGB and 71.8% DCI P3, making it viable even for video/photo editing.

Here is a link to the calibrated display profile of the reviewed unit. Because each display is unique, this profile will not perfectly match other displays of the same model. Still, using this profile should give better overall colours.

[ntab Temperatures]

Lenovo Legion 5i cooling system
Lenovo Legion 5i cooling system

The cooling solution of the Legion 5i consists of three heat pipes (one of which is shared between the CPU and GPU), four heatsinks, two cooling metal plates that cover the VRMs and VRAM, and two medium-sized fans. The fans pull fresh air from underneath the laptop and push it out throughout its sides and back. Even though the bottom of the chassis looks like it has many holes through which the air can come in, opening the back panel reveals that a thin plastic plate blocks these holes. Therefore, the air comes in only through two areas on the bottom of the laptop, which are the same size as the fans.

Because the laptop pulls its fresh air from underneath itself, a cooling pad will make a noticeable difference for the laptop’s internal temperatures. Even though the machine has no problem keeping the temperatures in check, a cooling pad would be especially useful for improving the laptop’s long-term reliability.

The laptop’s performance was tested in both real-usage scenarios (like gaming) and synthetic benchmarks with its Thermal Profile set to Performance mode. After testing over 40 games from a wide variety of genres and on various graphical settings, it is clear that this laptop has excellent thermal management. Even in the most graphically demanding games, the CPU’s temperatures hovered between 75-85° C (167-185° F). Furthermore, the average all-core boost remained at 4.28 GHz, which is almost Intel’s guaranteed all-core maximum boost of 4.30 GHz. Occasionally, some of the cores did drop for a split-second to as low as 0.79 Mhz. However, these drops did not seem to have any noticeable impact on the system’s overall performance.

The synthetic tests yielded similar results:

All temperature measurements were performed at an ambient temperature of 26° C (78.8° F).

Temperatures on idle and heavy load

During the standard 30 minutes AIDA64 stress test (CPU, FPU, cache), the processor reached an average temperature of 81 °C (177.8 °F), with a maximum of 94 °C (201.2 °F). At these temperatures, the processor managed to keep an average frequency of 3.95 GHz, with occasional dips to as low as 3.88 GHz on some of its cores. Given that the i7-10750H has a minimum guaranteed frequency of 2.60 GHz and a maximum all-core boost of 4.30 GHz, it is safe to conclude that the cooling solution of the Legion 5i is adequate for its processor.

In the combined AIDA64 plus Unigine Superposition test (which had both the processor and the GTX 1650 Ti under heavy load for 30 minutes), the processor reached a maximum temperature of 91 °C (195.8 °F) and throttled until it settled at a temperature of 82 °C (179.6 °F). Despite its throttling, the processor still managed to keep an average clock speed of 3.71 GHz with occasional dips to as low as 3.58 GHz, which exceeds the minimum advertised clock speed of 2.60 GHz. The dedicated graphics card maintained an average clock speed of 1608 MHz with a maximum boost of 1905 MHz. Temperature-wise, the video card hovered between 64 and 66°C (147.2 – 150.8°F).

Finally, the laptop was tested with the AIDA64 stability test, which is another combined stress test for the video card and processor. The results were very similar to the previous stress tests. The processor reached a maximum temperature of 97°C (206.6°F) and throttled until it settled at a temperature of 80°C (176°F). Despite its throttling, the processor still managed to keep an average clock speed of 3.81 GHz with occasional dips to as low as 3.68 GHz. The dedicated graphics card maintained a clock speed of 1866 MHz with a maximum boost of 1890 MHz. Temperature-wise, the video card hovered between 64 and 66°C (147.2 – 150.8°F), which is excellent for a gaming laptop.

After all the tests conducted by the Noteb review team, it is safe to conclude that Legion 5i’s cooling solution is more than adequate for its components. The laptop manages to keep its temperatures in check in any scenario, allowing the processor and video card to reach their full potential, while also prolonging the laptop’s life span.

[ntab Noise]
Even though the user cannot set a custom fan curve, Lenovo lets the user choose between three predefined Thermal profiles. Changing the fan profile is done by pressing the Fn + Q keys. The active thermal profile is visually represented by an LED indicator inside the power button, changing colours in blue for “Quiet Mode”, white for “Balanced Mode” and red for “Performance Mode. There is even an option to allow the laptop to automatically change to “Performance Mode” when it detects a game running. When idling, the fan noise is hardly noticeable, generally remaining at the room’s ambient level of around 24 dB. Even under intensive usage, with fans set to their maximum speed, the noise level reaches ~40 dB, which is quieter than most gaming laptops tested so far by the noteb.com team.

The LatencyMon test evaluates if a laptop is suitable for video/audio editing and recording. The laptop was tested while connected to the Internet with a network cable and while connected via WiFi. Throughout the test, the machine did not experience any high latency, which makes it ideal for sound recording. The test was run multiple times to eliminate any flukes, and it always returned with the same results.

The laptop has two 2-watt speakers placed at a slightly inclined angle to avoid muffled audio, and while they are not as loud as other laptops, they are better sounding than most gaming laptops tested so far. The highs are clear, the mid-tones are great, and there is even a little bit of bass, even though there is no subwoofer. But even so, it is still recommended to use a pair of headphones for an improved listening experience.

Since most laptops are used on battery for mundane office activities and web browsing, the laptop was tested using a simulated continuous web browsing session over the WiFi. The browsing session involved checking emails/news, social media and accessing multimedia websites, similar to the behaviour of an average user. The level of brightness was set according to visibility and usability. At 60% brightness, the laptop provided an enjoyable viewing experience. The sound volume was also set to 50%.

With its 80 WHr battery, the laptop lasted 5 hours and 30 minutes. The machine was tested using both Firefox and Edge and yielded similar battery life results regardless of the browser. Also, Nvidia Optimus was enabled for the entire duration of the tests, meaning that the laptop should have only used its Intel integrated video card.

Charging the laptop from 5% to 100% took almost 1 hour and 55 minutes with the 170W power adapter included in the box. The charging test was done without activating the “Rapid charge” option, which fast charges 50% of the battery in 30 min.

Also, it is worth mentioning that some versions of the Legion 5 come with a 60 Whr battery instead of the 80 Whrone found in this review unit. The versions with the smaller battery will undoubtedly have a shorter battery life, which can be estimated at around 4 hours.

[ntab Conclusion]

Pros:

  • good performance for 1080p gaming;
  • great color coverage display;
  • excellent keyboard;
  • outstanding cooling;
  • competitive pricing;
  • a wide selection of peripheral ports;
  • good upgradability.
  • above average battery life;

Cons:

  • lack of a card reader;
  • no Thunderbolt;

In conclusion, this laptop is a jack-of-all-trades and master of them all.

While there are cheaper gaming laptops out there, such as the Acer Nitro 5, these laptops offer great value for the money because they focus only on budget gaming and neglect other areas. For example, the Acer Nitro 5 has inadequate colour coverage, poor speakers and below-average battery life.

On the other hand, for the same money or slightly more, other gaming laptops might offer a better dedicated graphics card and higher framerates. But apart from gaming, the Legion does so many other things right, that it is worth every penny even though it may not seem at first as the most cost-effective gaming machine out there.

The Legion 5 is so versatile that it can excel in many different scenarios: it can be a budget gaming laptop offering excellent 1080p gaming performance, it has a display which can be used for photo/video editing, it has an excellent keyboard, and it is quiet enough to take to a classroom. Moreover, it has over 5 hours of battery life and a business look that enables it to pass as a work laptop easily. All of these traits are paired with an outstanding cooling solution and build quality, making the Lenovo Legion 5i one of the best gaming laptops of 2020.
