My stylus lithium-ion dremel wont turn on what is wrong with it

SOURCE: My dremel stylus wont turn of and I dont know what

its probably broken, but you could just add a foot operated switch from a hardware store which costs about 4$, which is cheaper than replacing the switch and easier to turn off and on while using the tool.

The battery has been overcharged.
You will need a new one.

Thanks!!!!

Change the capacitor 220uF and it will most certainly work again. I got the idea from FixYa and it solved my problem!
Easy to change just 2 soldering points and a component costing around 0,2 Euros. If you do not know how to operate a soldering tool ask someone for a quick assistance. The switch takes around 2 min (1,5 min to open the charger and 0,5 min to change the component!).
