I double checked it, and it does have 11.5VDC across the connector when it
seems to pull in.
Two of the 4558s on A103 have -10.5VDC on pin 4, and 11.5VDC on pin 8. The
third 4558 seems to have pin 4 grounded (according to an ohm meter), which
seems strange, to say the least.
It's up to you, it's your drive. And don't
you think the HDA has been
opened before? If that's the case, then it might not do any more daamge
to pull the cover again.
The seals that cover the screws have been broken, so the HDA appears to
have been opened by someone in the past.
