Cons
- Large and heavy at about 3.5 kg before the 400 W charger, and the fans were loud under 3D and CPU load in review testing
- Battery lasted under two hours under full load in review testing despite the 99 Wh capacity, and power draw was high
- SSD speed throttled under continuous load in review testing
- Measured SDR brightness was about 470 to 560 nits in review testing, well under the 1,200-nit peak rating, which is an HDR-class figure (one review measured 828 nits in HDR)
