Comment (by rsmith):

 Replying to [comment:9 cjb]:
 > I should point out that I wasn't removing battery/AC from the laptop
 after reflashing the BIOS, and Mitch says he's lately seen some weird
 behavior when you don't do that.  So perhaps that's our problem -- we
 should especially look out for cases where some reflashes, leaves power
 off for > 10 seconds, and then *still* sees the shutoff.

 Mitch: What command are you using when you do the power off after flash?
 In my battery testing I've seen that the EC reset line is asserted and
 that the EC reloads its firmware with out having to pull the battery.
 That is unless the power off command has changed since then.
