Lenovo IdeaPad Slim 3x (15", 10) review

The IdeaPad Slim 3x (15", 10) is a 15-inch Windows laptop built around a Qualcomm Snapdragon X X1-26-100. It has 8 cores, a boost clock of up to 3.0 GHz and a Hexagon NPU rated at up to 45 TOPS. It is a Copilot+ PC. Lenovo offers it with Windows 11 Home or Pro, and it starts at 1.5 kg in the OLED, 60 Wh configuration.

That makes it a portable-ish machine for people who spend the day in a browser, terminal sessions, documents and remote consoles rather than heavy local builds.

The chip has 8 cores and 8 threads. Notebookcheck reports power limits of 50 W sustained and 65 W for short bursts. Tom's Guide recorded a Geekbench 6 multi-core score of 10,505. Those figures point to a chip that handles everyday multitasking and moderate development work. Long compile jobs or several VMs would be a stretch for an 8-core part with no higher-tier option listed.

The 45 TOPS NPU matters mainly if you want Copilot+ features in Windows 11.

Lenovo lists 16 GB or 24 GB of LPDDR5x running at 8448 MHz. It is soldered to the system board, so you choose the amount at purchase and cannot change it later. With 16 GB as the base, it suits a handful of containers and a full set of browser tabs better than a stack of VMs.

Storage is more flexible. The laptop takes a PCIe Gen4 M.2 2242 SSD in 256 GB, 512 GB or 1 TB sizes. A second 2242 slot supports a 512 GB or 1 TB drive. That gives you room to add capacity later without replacing the first drive. The short 2242 format is worth checking before you buy a drive.

There are two main panels. The first is a 15.1-inch WQXGA (2560 x 1600) OLED at 60 Hz. The second is a 15.3-inch WUXGA (1920 x 1200) IPS at 60 Hz and 300 nits, with an anti-glare finish and an on-cell touch option. Both are 16:10, which gives more vertical space for code and documents than a 16:9 panel of the same width.

The IPS listing shows a 45% NTSC colour gamut. Owners complain about the display. If screen quality matters, the OLED option is the one to look at. The 60 Hz refresh rate applies to both.

Lenovo offers a 50 Wh or 60 Wh battery. Rapid Charge gives 2 hours of use from a 15-minute charge. Owners praise the battery life. The larger 60 Wh pack is paired with the OLED in the 1.5 kg starting configuration.

The charger plugs into a round DC port on the left edge. The USB-C port also supports PD 3.0, so you have a second way to charge.

Key travel is 1.3 mm, with an optional backlight. The hinge opens to 180°, which helps when you share a screen across a desk. The chassis is tested to MIL-STD-810H. The housing is ABS and polycarbonate, and the display lid is aluminium. Dimensions are 343.4 x 239.5/241.5 x 16.9 mm.

Owners complain about the speakers. For video calls and media, a headset or external speakers is the safer plan.

The right edge has one USB 3.2 Type-A Gen 1 port, an SD card reader, the power button and One Key Recovery. The left edge has the DC port, a second USB 3.2 Type-A Gen 1, HDMI 1.4, a USB 3.2 Type-C Gen 1 with DP 1.2 and PD 3.0, and a combo audio jack.

The SD reader and two USB-A ports cover cameras, drives and older peripherals. The only USB-C port is Gen 1, and there is no Ethernet port. If you plug into wired networks often, you will need a dongle, and it would take the USB-C or one of the USB-A ports.

This is a sensible pick for someone who wants long battery life, a big 16:10 screen and room to add a second SSD. The OLED option gives the display a clear way to improve. The soldered memory, the basic USB-C port and the lack of Ethernet are real limits. Owner complaints about the display and speakers are worth weighing too.
