I just changed my car's old dead battery with a new, just purchased one following the directions here. Even though I clamped the connectors down hard enough that I can't move either of them, the car seems to be completely dead --- it doesn't appear to be getting any power whatsoever. Any ideas what could be wrong? [more inside]

Car with a dead battery (sorta). I want to sell it immediately. Will I be better off selling it to a used car dealer or on Craigslist? If the former, can anyone recommend a dealer in Seattle? [more inside]

I have a Dell laptop with a dead battery and no AC adapter at hand. Can I network the Dell to a Vaio and run the Dell off the Vaio's power supply?

Is there anything I can do to make my laptop battery last longer? I've had two HP laptops, and within months the batteries in both of them stopped holding a full charge. Presently, the icon indicates a fully charged battery, but when I unplug the laptop the battery dies within 30 minutes. Is this an HP specific problem? Is there a "better" kind of battery I can buy?
