I've lost the charging dock and AC adapter for the Logitech MX Revolution mouse. There's no way to charge this mouse without the dock. I think I can pretty easily build a new dock on my own, I'm just looking for owners of this mouse to answer a technical question to help with construction. [more inside]

My old laptop blew the motherboard after 3 years of great use (Acer Aspire 5670). I just bought a new laptop (Acer Extensa 5630Z). Can I use the power charger/AC Adapter from my old on my new without doing damage? The new one is rated 19V 3.43A. The old one is 19V 4.4A. (plugs are the same). Long live the hive mind!
