Thanks a lot for the solution! The wife was in Italy. I text her and ask why she has not been skyping me all day. SHe replies that the keyboard is dead on her new computer. I call her at her hotel in Italy. Suggest some basic things--no go. I ask her what she had done last on the thing, while it was still working. It turns out she too had turned on the machine when it was in tablet mode. While she's on the phone, I look it up on the web, and wind up here. I have her pull out the battery (explaining that to her was like pulling teeth!), and Presto! Thanks a million for posting this.
