So I have been seeing a lot of people looking for a fix for this issue.  This is the cheapest work around available.  It’s going be about 40 dollars total but it will allow you to use your sidekick 3 again.

The Sidekick 3 has a charging issue that crops up after awhile. The unit will fail to charge at all even though you may get the charging light.  Not all models do this, but I have seen enough people asking about it on Yahoo Answers and Fixya to know that it is a widespread problem.

If you are under warranty, great! Send it in and get it fixed.

If not, buy an extra battery and a Sidekick 3 charging cradle . This will cost about 40 dollars but it that is a lot better than the 100+ it will cost to fix it!

When looking at a cradle, make sure it says it has a spare battery charger. Some of the Sidekick Charging cradles don’t.

If you decide to go this route, make sure to power down your sidekick 3 before changing batteries.  This will  save the data to the flash memory and  prevent it from being lost.  If you remove the battery while the sidekick is on, it will do a hard reset and your data will have to download again from server, and will take awhile.
