Psion's own specification: 58-key keyboard, 15 V 1.5 A adapter, up to 8.5 hours battery life with a 2.5 hour recharge, CR2032 backup cell with a 55-hour lifespan, PC Card slot rated for 3.3 V and 5 V, 0.7 m drop onto carpet, IP30.</ref> — the community FAQ says 15.5 V — and no other Psion adapter matches either figure.<ref name="faqpower" /> | ||
The '''lithium-ion battery pack''' is the genuine hazard. Do not puncture, crush or short it, and read [[Battery Refurbishment]] before attempting to open one. | The '''lithium-ion battery pack''' is the genuine hazard.

The netBook's case is plastic rather than the Series 7's leather, so it needs nothing beyond a barely damp cloth. It carries the same '''15 V, 1.5 A''' supply requirement<ref name="ds2001" | The netBook's case is plastic rather than the Series 7's leather, so it needs nothing beyond a barely damp cloth.
