So I've searched for a good hour or so and I can't seem to figure this out.

When I unplug and roam around with my T400 the hard drive light on the bezel is constantly lit up and not blinking. The hard drive is also hauling it's butt off and I can hear it as well as feel it under the palm rest. I've noticed this behavior only when I'm on batteries which in turn is killing my battery life.

I've looked for programs that might be accessing my hard drive constantly and couldn't find any clear cut winners. My anti-virus is Avast Free and this is Windows 7 Ultimate 64bit. Might it be some Lenovo software??

Any help would be appreciated as this is driving me nuts.

Have you unticked drive indexing?

Yup I did but just to make sure it's the one where you right click on "C:" , then properties, and then go disable indexing on the first tab at the bottom?

EDIT: I also did the services.msc and stopped+disabled Windows Search.

I'm not sure... when I received my T400 it had Vista Basic on it and it exhibited the same behavior. I installed XP Pro because I did not like Vista and XP Pro did the same thing also. I never did find out what caused that blinking and resorted to ignoring it. Nevertheless it is a PITA. I'm afraid I don't know what else it could be! I've since switched over to SSD. No problem with the hard drive being accessed constantly anymore

Thanks for the help. I don't know what it could be either. I had issues like this on my old T41p and I think it was something with the IBM Software.

When you say 'roam around', are you saying that the hard drive light stays on when you are carrying it around, but when it is laid down it is normal? If so that is the normal function of the drive protection system. (APS)

Sorry - I meant 'roam around' like if I'm mobile with the laptop aka away from my desk. I always close and put the laptop to sleep when I move it. I'm talking about as soon as it's resumed from sleep the hard drive light is always on. I also always sit at other tables and never put the laptop on my laptop or any other non-flat surfaces.

Go to task manager, performance and click Resource Monitor, go to the disk tab and check what might be accessing the disk. Might be the AV doing a scan in the background too.
