Review Lenovo Yoga Slim 9 14ILL10
Lenovo Yoga Slim 9 14ILL10 · Core Ultra 7 258V · Arc Graphics 140V
Intel Core Ultra 7 258V · Intel Arc Graphics 140V · 32GB LPDDR5x-8533 (onboard) · 1TB SSD (Samsung PM9C1a) · 14″ 3840×2400 OLED 120Hz · 1.241 kg
Reasonable core temperatures and fan noise – high performance-per-watt,
long battery life, attractive and shiny chassis design,
good GPU performance for the size, good quad speakers for the size.
Disappointing webcam quality for a 32 MP sensor,
limited port selection, no 3.5 mm audio jack,
no major boost in CPU performance, servicing could have been easier,
no support for M.2 2280 SSDs.
