#10 new defect

APM setting is forgotten after resume

Reported by: lewisr Owned by: stevenhl
Priority: minor Milestone: Release-1.8.16
Component: danis506.add Version: 1.8.9
Keywords: apm noise spindown resume suspend power Cc:



Replaced ThinkPad? T43 internal drive with a Western Digital 320GB 5400 RPM Scorpio Blue (WD3200BEVT). These new "green" hard drives spin down quickly, locking the heads, which results in an audible (and annoying) "click!"

DaniS506.DOC refers to /APM switch, and provides basic guidelines for setting the /APM:n value. 254 is the *lowest* acceptable value (vs 255, which switches off the circuit, entirely) providing for quiet operation (at the expense of some battery power). (See for more background, if necessary.)


System boots and runs fine. System suspends without incident (APM.SYS is at 10.156 level; no ACPI on this machine). Upon resume, drive reverts to default behavior, of clicking every 8 or 9 seconds.

Expected behavior:

Just as Dani queries the removable bays for changes upon resume (in case of a warm swap), Dani should query/reset the non-removables upon resume, so that the boot time configuration is preserved.

Dani details, disk info, etc.:

See attachment.
