Thank you for the feedback. I have installed the APS, with no problems
seen for the last 2 days.
Just curious, how does one know that APS kicked in and stopped the HD?
I guess it would be evident if the laptop was reading/writing when
becoming unstable, but not otherwise. Would I find a record in Event.log?

We have an X61s that is configured as an instrument
controller for an optical spectrometer used in the
field. The APS prevents writes to the disk when we
walk with the instrument, our standard way of using
it. We have to turn APS off to collect useful data.
Note that this is a rather specific issue with APS
but is a real problem for us.
We intend to get around this by installing a SSD
in place of the (slow) hard disk. Then there will
not be a need for APS and we won't load it.

Yes, I was looking for some feedback from people that have this
protection running. Did it help? did it cause other problems?
I have looked into the lenovo forums, but could find nothing really
helpful.

Upgrading a t61p, Thinkvantage System Update offered me
this Active Protection System.
According to Lenovo,
Like an airbag's sensor, Active Protection System can detect sudden changes in
motion and temporarily stop the hard drive to help protect your valuable data
from some crashes that could occur due to everyday notebook accidents.
This would seem to be quite helpful to have on a laptop.
Does anyone have experience in using it? Should I install it?

Serenella,
This is the shock detection system for ThinkPads. It detects
sudden G changes and lifts the disk heads (retracts) for a short
period of time.
I'm not sure how helpful it is, since I've had two thinkpads come
back to me after being dropped (APS enabled), but it can't hurt.
Just don't assume that you're protected.
I'd like to see real world data that suggests it really works.
Pointers welcome!
