| On a slightly related note, fun tip. If you have a 'dead' laptop

| 'jumpstarted' some by connecting to a li-ion cordless drill
| battery for a few minutes.
|
| I've managed to get a few old mobile phones back to life using
| this method.
|
| Edit: as a safety note this is not recommended! Please read some
| of the comments below!

| This is, in general, a bad idea.
|
| Lithium battery charge circuits generally have a fully charged
| voltage (about 4.2v), a fully discharged voltage (about 3.2v),
| and a 'do not attempt to recharge below this' voltage (about
| 2.4v).
|
| The reason circuits are designed not to recharge a cell below
| the 2.4v threshold is because when you recharge below that
| voltage, gasses are typically generated which eventually (many
| months later usually) burst the plastic envelope of the
| battery, and the battery electrolyte then evaporates as a
| highly flammable gas, killing the battery and potentially
| starting a fire if there is a nearby ignition source.
|
| TL:DR:. 'dead' batteries refuse to charge for safety reasons,
| and tricks to bypass that safety mechanism might lead to a fire
| a few months down the line.

| Now I regret that I got rid of it when it didn't boot. :(

| Apple product of all time just for the "what could have been"
| factor, but the Adobes of the world balked at "rewrite your
| apps in Yellow Box" so we got Carbon and friends in the
| rebooted Mac OS X project. There was one retail release as "Mac
| OS X Server 1.0", but the "Premier" desktop-user-focused
| version was canceled. I like to run Rhapsody on my Power Mac G3
| Blue&White because that particular machine shipped with
| Rhapsody (in a Server G3 configuration) and is extremely well
| supported: https://cooltrainer.org/images/original/michiru-
