There is a Bottom Cover Tamper Detection feature. Each time the base cover is removed, you have to attach to AC to boot, with battery installed or not.

Hope this helps.

No that's not how tamper thing works, by default damper switch is disabled inside bios but if you etc have a bios pass and so and enable tamper thingy it will then block user from being able to boot the laptop since it will throw a alert on the screen saying "Tamper Alert back cover opened" or something like that and that box won't disappear untill back cover is back inplace then it will boot again as normal, About your question is try pressing reset button and then connect ac to power it on then disconnect ac that should bring battery back to life.
