All mobile phone manufacturers have agreed to a common standard for chargers. What about laptops? My Toshiba runs at 19v - why? Nothing else in the world runs at that voltage. It must be a ploy to make you buy one of their own replacements, at £70-£80 a go. Not all the connectors are compatible with each other, so we need the mobile phone approach: standardisation.
And as an aside, why does my laptop battery give up after .45 minutes, and why does it overheat and shut down after 1 hour?
