Replace the big yellow cap on the mainboard, it is a 47uF tantalum, then the brown one, it is 22uF.

There could be other cap colors installed on different model releases, but most I have seen are the other way around as per attached image. The brown 47uF is across the switched battery supply which on the circuit board design, is where marked.

cheers
