What to check before buying

  • Costco membership is required. Confirm the £699.99 total before payment; the £100 saving is valid 11–22 September 2026 while stock lasts. Warehouse prices can differ.
  • No charger is included. Lenovo specifies USB-C Power Delivery at 45–65W; buy a suitable adapter and cable if you do not already own them. Charger cost is not included in the deal price.
  • The screen is non-touch, 60Hz IPS with 45% NTSC colour coverage, not OLED or a wide-gamut panel for colour-critical work.
  • The UK keyboard is non-backlit. Memory is 8GB soldered plus one populated 16GB SODIMM; Lenovo's stated maximum offering is 24GB.
  • Integrated Intel graphics are intended for everyday work rather than demanding gaming. The six-core processor is not a workstation-class chip.
  • Lenovo lists a 60Wh battery and starting weight of 1.63kg. Advertised battery runtime is not an independent measurement.
  • Costco includes a two-year warranty, distinct from Lenovo's one-year base warranty. Delivery is estimated at three business days, with postcode restrictions.

Why it is worth considering

A useful 24GB Windows work option below £700 for Costco members, with a bright matte screen and two-year retailer warranty. The extra memory is the main draw; the 60Hz, 45% NTSC panel is not a colour-work upgrade over cheaper OLED alternatives.

  • The exact basket totals £699.99 including shipping after an automatic £100 reduction.
  • 24GB DDR5 combines 8GB soldered memory with a 16GB SODIMM, providing more headroom for multitasking than a typical 16GB configuration.
  • The 15.3-inch 1920×1200 matte IPS screen is specified at 400 nits; the taller format is useful for documents and spreadsheets.
  • Two M.2 storage slots, Wi-Fi 7, an SD card reader and a 1080p IR camera add practical work features.
