HDD APS chipset [with pic]

[sbux4622]

I posted a message several months ago. My T41 (2373-9FH) did not POST after powering up. Eventually I sent it to my friend's store. It was returned two days ago, and I took it apart to check the replaced system board. Funny things were identified.

1. Upon checking the board was 2373-4TG. The original video chipset should be ATI 7500. Somone upgraded it to ATI 9000! I wonder the board was fixed before.

2. HDD APS disabled. In Windows APS program was greyed. PC Doctor did not run checking on APS. I read T41 HMM, realized that the accerometer chip was absent. Could any expert confirm it to me? http://cid-bec411ccff721801.skydrive.li ... ll%7C6.jpg
