Thinkpads Forum

I was just browsing through the HMM for the Edge E420s when I saw the "Emergency Reset Hole" in the diagram for the bottom of the laptop. What exactly does this button do?

I'm not asking for a BS generic explanation like this:

I really would like to know what function this button is actually doing.

Thanks!

It acts like the reset button on desktop computers - equivelent of pulling the power, which is important since you cannot pull the battery on those systems to remove power (this is why most other thinkpads don't have this button - you pull the battery, instant reset); it stops everything and performs a cold boot.
