Video freezes temporarily when laptop shakes

When watching videos on my lenovo thinkpad t61, the video freezes temporarily if the laptop shakes (i.e. if I am on a bumpy train). Usually the audio continues when the video stops, and then the video will "catch up" such that the video and audio will be in sync.

 

I assume that this is a natural problem - that there is a temporarily pause when the laptop shakes - but I am wondering if this is an especially bad problem with lenovos? Also, is there a term for this, so that when I buy a new laptop, I can know whether the new laptop is particularly susceptible to this problem?

Re: Video freezes temporarily when laptop shakes

It's Lenovo's Active Protection system. It's the airbag protection. You can lower the sensitivity in control panel.  It will learn which vibrations are normal. It parks the head on the hard drive when it senses that it's going to fall.

 

There's actually a picture of a laptop when you open the program and the picture moves the way you move the laptop. If you shake it, the picture shakes.

Here's a movie of it.

Re: Video freezes temporarily when laptop shakes

That's cool that you were able to point me to that, thanks. For some reason, however, I'm unable to click or adjust any of the settings. All of the boxes/options and the "shock detection sensitivity" scroller are unchangeable. Any ideas why or how to fix this?

Here's an overview of the system, see if this helps.  If it doesn't, post back.

 

Are your settings grayed out?

Thanks for the link. Yes - almost everything in the graphic under "properties and settings" is grayed out.

Are you logged in as adminstrator when you bring up the options?

Re: Video freezes temporarily when laptop shakes

What OS are you running and is it 32bit or 64bit? And what is the four digit  model of your laptop?

Most likely this problem is a result of ThinkVantage Active Protection System settings that are too sensitive. See Active Protection system overview for more information about APS.
