How to fix a Leica Rugby 100 laser level that won't turn on?

If your Leica Rugby 100 laser level doesn't turn on, it could be due to a low or dead battery. If using alkaline batteries, replace all four D-cell batteries with fresh ones. If it uses a rechargeable NiMH battery pack, plug the battery charger into the Rugby's charge jack first, and then into a standard electrical outlet. Connecting in this order prevents potential sparks.
