I'm hoping it was just choosing High Performance power mode, as after doing that, and making sure under Processor power management, then Minimum processor state that Plugged in is set to 100% (meaning the CPU will never go to a lower rate), I have been good for 10 minutes. Hasn't gone this long yet. (Again, this is just after installing it, so it may lock as I type this).
(Also, I'm typing this on my work laptop, HP 8760w laptop, also VERY nice.) System SKU B2A83UT#ABA
Anyway, thanks again for the help. By the way, I made sure I got the 128GB Vertex 4 to the 1.5 firmware release before installing. It is rather zippy.
So far so good, let's hope it stays...
