Lenovo ThinkPad L15 Gen 4 (Intel) review – sturdy business notebook that offers good comfort under load


Verdict

The Intel version of the ThinkPad L15 Gen 4 is a typical Lenovo business device that simply gets the job done no matter the task. Yes, the build is plastic but it’s also sturdy which is nice to see. Still, you can’t open the lid with a single hand. Considering the price tag of this laptop, the successor should be improved in this section.

The spill-resistant keyboard is comfortable for work. It has a long key travel, clicky feedback, an optional backlight, and a NumPad. The well-known TrackPoint is here and it could be an important extra for some users. The touchpad is smooth but the accuracy isn’t the best one that we’ve seen so far.

The notebook feels snappy which is good for daily and office usage. Our machine has an Intel Core i7-1355U. The CPU can maintain a high P and E core clock thanks to the decent cooling with two heat pipes. It’s kind of strange that a much thinner 14-incher as the ThinkPad T14s Gen 4 can show even higher frequencies with the same CPU. The overall performance of our gadget could be even better if the memory was working in a dual-channel mode. In our case, we got one 32GB (2Rx8) memory stick that works in a single-channel mode which isn’t an optimal solution if you want the full CPU and iGPU power at your disposal.

This reminds us that the upgradability of this laptop is decent – two SODIMM slots for up to 64GB of DDR4-3200MHz RAM but there is just one M.2 slot for Gen 4 SSDs. One of the main advantages of this device is the comfort under load. Even when the CPU is stressed at max, the single fan is almost quiet and the keyboard is just a bit warm.

The I/O looks good with its many ports including a Thunderbolt 4 connector, microSD card reader, and an Nano-SIM card slot for optional 4G connectivity. The 1080p IPS panel (Innolux N156HCA-E5B (LEN40BA)) is suitable for long hours of work because it’s PWM-free and has wide viewing angles. Alright, the sRGB coverage is low but that’s not that important for an office laptop. The battery life is normal – 8 hours and 20 minutes of Web browsing sounds okay for a 57Wh capacity.

The Lenovo ThinkPad L15 Gen 4 (Intel) is a good business device that offers a sturdy build, many security options, a great keyboard, and nice comfort under heavy load.
