I have the same issue, the light is orange but the Kindle won’t turn on. I ordered the battery at www.batteryupgrade.com. But they have some misleading info on their website so they sent me the wrong battery even if it states that it supports Kindle Paperwhite 2012. Check the connections on original and on the new battery. In my case the battery looks the same, but the connections doesn’t. Now I’m waiting for the new one …
