Review on Lenovo Legion Y540-15 Gaming Laptop 81SX00NNUS: Intel Core i7-9750H, 16GB RAM, 512GB+1TB Storage, NVIDIA GTX1660Ti, 15.6" IPS Display by Micha Pyra ᠌

Revainrating 4 out of 5

I am satisfied with the product, it is made well, the price is also pleasing.

Config: Y540-15IRH-PG0, i7-9750H/16GB/1650/NVMe 1TB/FreeDOS/BOE CQ NV156FHM-N48 60Hz display (overclocking gave a maximum of 65Hz even with Pixel Clock Patcher, unfortunately). The undervolt is stable at -150mV per core, -150mV per cache. The ThrottleStop program also advises turning off the Power limit and setting 40W / 45W for a long and short boost of the processor for lower temperatures and even more stable operation. The same assembly of the Chromium browser already held 3.5GHz / 85 degrees. Webcam of decent quality, except that the location is below. The battery life is adequate "about 4 hours" in a gentle mode with wifi at low brightness. Could have put more battery, to be honest. Who cares about compatibility with Linux: to run something, you either need to use proprietary drivers (you need to add nouveau to the blacklist at startup), or sit on the built-in video card. The touchpad under Linux works better. Under Linux, the whistling from the coils disappears, and no matter what load goes to the laptop, I don’t know what it is connected with. Noise fix for Linux, fixes wifi adapter output power at 10mBm: sudo iw phy#0 set txpower fixed 1000

Pros
  • Perfectly eats up any tasks: two Android Studios, a browser with a bunch of tabs, an emulator and a video player? Easy. Rainbow Six Siege at a stable 200+ fps on low (and I took it with the expectation of a powerful percentage) / 140+ on ultras? Easily. The cooling is at the level, it works silently at a low load, but under a serious load it is expectedly noisy, the microphone does not cause problems and discomfort. At peak multi-hour load on all cores, without changing the initial configuration, the temperature was 90 degrees without throttling (see the comment about undervolting and a possible decrease in temperature with higher performance), the frequency remained at 3.3 GHz when assembling chromium. Surprisingly, the weight and dimensions are small for such iron. A really comfortable keyboard (except that the numpad is small, but I don’t use it), a clear soft-elastic click, the backlight can be turned off completely (and who needs to turn it on, there is plenty of brightness). The touchpad is matte, comfortable and in general there are no complaints, harsh buttons and drivers under Windows do not allow reaching the ideal - they leave much to be desired in terms of responsiveness even after choosing the most responsive profile in the settings, the problem is with the software (see comment). The body feels quite reliable: it does not creak, the solidity of the assembly is good. Inside is a pleasant and extremely easily soiled soft-touch, it is easy to clean. I can’t say much about the screen, I’m not an expert, most likely it won’t work for really professional work with color, but the colors and contrast even without changing the profile are much better and more pleasant than many laptop TN and cheap IPS on which I had to sit, and in general the screen is rather a plus . However, the matrix has a slight backlight bleeding in the upper left corner, it is non-critical and does not show up in any way. Someone may not have enough maximum brightness (peak brightness is lower than a MacBook, for example) in a very, very bright environment, I have never noticed this behind me (brightness is at 90%). And in general, for such money, they could report 144Hz.
