Power adaptors recharge the battery while the system is Off, On, or in Sleep mode. It also powers the system if you choose to operate without a battery.
Designed to be the perfect travelling companion, these adaptors have a clever design that allows the DC cable to be wound neatly around itself for easy cable storage. Also a magnetic attachment designed to separate if the lead is pulled. Avoid putting your laptop away with the power lead still connected to it – or fraying of the lead near the computer (or near the adapter block) seems the result and they are not cheap to replace
