I ended ordering a used one from eBay, which should be arriving today. I guess on the up-side, I will have two keyboard docks, two chargers, and a ‘parts bin’ of the fried tablet to scavenge parts from if there’s any further issues down the road.
I will keep tinkering with the fried one and let you know if I figure anything out. Since you mentioned the batteries, I think i’ll pull them out and test them on my bench-top lithium battery charger, to see if they are working. I suppose it’s possible there is an internal protection fuse wired in the pack that I need to find. Probably wishful thinking 🙂
