X-BeenThere: freebsd-acpi@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: ACPI and power management development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 27 Apr 2004 15:52:23 -0000 I've been playing with adaptive power management for my Thinkpad T40, running an up-to-date current with ACPI. While I can cycle the clock on demand, I'm noticing that once the fan comes on, it stays on. Judging from the visible variables, there's not a lot of control there. I even notice the lack of battery time, though I get a coherent number from apm. Can I do anything to remedy this? I'm running BIOS 2.03 and have tried a slightly patched DSDT with little visible difference. There is a later BIOS, but as I don't have Windows or even a floppy, it's a pain to try (also I've really been burned by IBM BIOS upgrades before on an older A20p).
