Powerbot won't turn on at all

I have had my Powerbot R7070 for a bit over a year now, so it’s no longer covered by warranty.

Recently it stopped turning on, and I was told the problem would likely be with the battery. So, I ordered a new battery and replaced it.

The powerbot still won’t turn on.

I have followed directions on samsung’s support website, about letting it charge for a while, then toggling the emergency switch off and back on, then holding down the start button, but there’s no indication of the powerbot getting any power.

I also checked the charging dock’s charging pins with a multimeter, and it seems to be working fine, so something is wrong with the vacuum itself.

Any ideas?
