why is there a sticker underneath my laptop cpu?

[rajah99]

I bought a dell vospro 1700 laptop recently. The previous owner had upgraded to a penryn, t8300, and bought an ES model from ebay.

Anyway, turns out both the heat sensors are not functioning, and also the dell diagnostics was showing a duff CPU THERMISTOR.

I decided to open it up and apply some new arctic silver, given i couldnt rely on any cpu temp monitoring.

I took the cpu out, and then discovered a round sticker on the underside?? Check out the pic:

Anyone know what or why this is there? I thought maybe thats the reason I was getting sensor errors, at least from the dell diagnostics.

So I used a pin and removed it. On rebooting, still not getting any sensors. But im wondering why would someone stick a sticker on the underside of a cpu?

where else would you put one?

Is that the "if you can read this you've just voided your warranty" sticker?

Quality Control sticker perhaps?

The place the original owner bought it from could have put it on there if it was an OEM CPU.
