Using APM or ACPI? On T21 (2647-4AU) when I switched on APM (apm=on acpi=off) pressing Fn-F4 resulted in blanking the screen and hanging the entire machine (the fan was still working, the standby led was off, and I could not power it on again). I have the newest BIOS. With ACPI I had to configure acpi events (vanilla install puts almost nothing in /etc/acpi/events) and with Fn-F4 I can put the notebook to standby (echo 3 > proc/acpi/sleep ) but the Ultrabay led is still on, and I can only wake it up with power button (not Fn). Fn-F3 is also not functional (it does not generate events, and other S states are not very functional anyway). Maybe there is an updated DSDT for T21 somewhere on the web? Also the ACPI CPU power states were annoying - my notebook emits strange hum when CPU is in C3, I had to disable CPU power management in BIOS completely to get rid of this, but maybe there is a better way (for example, to limit allowed states to C1 and C2 only, or change them manually, similarly to throttling)? Any ideas? :-) Piotr Gawrysiak -----Original Message----- From: Peter Eddy [mailto:petere@xxxxxxx] Sent: 26 May 2004 16:51 To: For users of Fedora Core releases Subject: Re: FC2 on Thinkpad T21 Gawrysiak, Piotr (GILW) wrote: > Anyone installed Fedora Core 2 on IBM Thinkpad T21 and got suspend, > standby and hibernation working?

Not a T21, but I didn't have any problem on my T20 Peter -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: http://www.redhat.com/mailman/listinfo/fedora-list
