H135953 - PC 300 HARDFILES ENTERS APM MODE PREMATURELY SYMPTOM: IBM PC 300 Series 6576 & 6586 systems running OS/2 2.X or OS/2 WARP 3.x with APM (Advanced Power Management) enabled, may intermittently put the hardfiles in a power managed state every 60 seconds. PROBLEM ISOLATION AIDS: The user enables APM mode via the Setup Utility and determines the time frame in which the hardfiles will enter a power managed state. The minimum time is 20 minutes. Systems affected by this problem will intermittently enter the power managed state every 60 seconds which slows system performance. FIX: Obtain and install an updated version of BIOS APM device driver APMBIODD.SYS. The BIOS APM update may be obtained from the IBM PC Company BBS system by calling 1-919-517-0001.
