I got a new lappy battery in the mail today. It came with one tiny piece of paper in three languages (English, French, and German, for those who care), and it says:
Battery Instruction Manual for Lenovo Battery Module
DANGER: If the rechargeable battery pack is incorrectly replaced, there is danger of an explosion.
DANGER: Fire or chemical burn hazard if mistreated.
DANGER: Keep battery pack away from fire.
DANGER: Do not attempt to disassemble it.
DANGER: Keep away from children.
DANGER: Do not taunt happy fun ball.
So I made the last one up. But this "battery instruction manual" does not come with any installation instructions. Or really anything beyond dire warnings about how I will die if I install it incorrectly. Thanks, Lenovo! Even though I'm fully capable of plugging in a new lappy battery, I think I'll wait for Patrick to get home so he can negotiate the 'splosion.
