Buying a Cybiko Xtreme that requires 'battery zapping' or 'kickstarting'? Here's how to get the battery going - at least it worked for 5 of mine in less than 6 minutes per Cybiko...
- Cybiko Xtreme with 'dead battery' - i.e. new, but won't hold charge.
- Soldering iron (can probably do this without it, but I'm not recommending it).
- Power adapter - 1000ma 3v to 5v - I used an Iomega Zip adapter.
- Watchmakers screwdrivers - crosshead.
- Plug in the soldering iron - let it get to temperature.
- While the soldering iron warms up, select the appropriately sized screwdriver and unscrew the 6 screws holding the case together - they're tight and quite soft, so don't chew them up - get a good fit.
- By running a plastic blade (or your thumbnail) around the join, split the case - it is clipped together towards the top, so you may find it easier to start at the bottom of the case.
- Carefully open the case like a book - there is a ribbon cable that you should take care to not damage.
- Note that the red battery cable attaches to the +ve mainboard connection, the black negative cable sits immediately below.
- Melt and disconnect the soldered connections that connect the battery wires to the mainboard.
- Set your multimeter to read DC in the range 0-10v.
- Plug-in and check the polarity of the power adapter connector. The Iomega Zip adapter has a positive tip, and gives a nice solid 5v reading.
- Holding the multimeter probes to the appropriate battery wire, touch the probes to the correct connector section.
Thus - Positive wire-probe-adapter, Negative wire-probe-adapter
- Watch the multimeter register 5v (or whatever your adapter kicks out).
- After a second or two remove the probe from the adapter - keep the battery wires on the probe though.
- If the battery is fit, it will continue to register a reading, otherwise repeat a few more times.
- When it holds a charge away from the adapter, remove the wires from the probes.
- Solder the wires back on to the mainboard and close the case - make sure you tuck in the wires without them running across the battery - the case should close really easily, if it doesn't check the lay of the wires.
- If after several attempts you don't get the battery to hold a charge, you're on your own... try replacing the cells... the battery pack is made up of two f6 prismatics in series (I believe).
- Plug the cybiko into the USB mains charger.
- The Cybiko should start and alert you that it is repairing Flash memory.
- The Cybiko should finish repairs within 30 seconds, and boot to the welcome setup screen.
- If there are any display issues, or the screen goes mental, then press the reset switch in the side.
- Charge the Cybiko overnight (at least 5 hours should do it).
