Thinkvantage active protection sensor diagnostics

I dropped my laptop. (ThinkPad T60p) 


At Boot time I get the message: Thinkvantage active protection sensor diagnostics.

Then: hard drive not found.


When I replaced the HD with a new one and tried to re-install the OS from the CD I get the same message:

hard drive not found.


What is Thinkvantage active protection sensor diagnostics?

How do I fix the problem?

Hi Eugene-Verne,

While installing Windows from the CD, did you set SATA AHCI to Compatibility mode in the BIOS? If the answer is yes then the hard drive connectors on the laptop may have been damaged due to the fall.

Additionally, you can try running HDD diagnostic program from the BIOS to see whether it is even being detected by the BIOS.

Hope it helps.
