Such is the case with the Lenovo ThinkPad 13 — it’s got a M.2 M-key socket, yet somehow only supports SATA SSDs in it, despite the CPU being new enough to support both SATA and NVMe effortlessly.

] | To anyone who has spent some time in photovoltaic (PV) power circles, the word ‘perovskite’ probably sounds familiar. Offering arguably better bandgap properties than traditional silicon cells, perovskite-based PV panels also promise to be cheaper and (literally) more flexible, but commercialization has been elusive.
