The laptop rebuild went well, but after adding some software I had an error I’ve never seen before, at shutdown: STOP 0x0000009F DRIVER_POWER_STATE_FAILURE. Recommended actions include removing any new drivers and even wiping the system. I’m installing Windows XP Service Pack 1 as well, for the first time, to see if it helps. If not, it means a wipe-and-load procedure. Put it this way: it looked great until some third-party software was installed, so it’s not a case of “blame Microsoft” this time.
