Really? I don't have TP here, but I found this at http://home.jp.FreeBSD.ORG/cgi-bin/showmail/bsd-nomads/10522 but it's from TP manual in Japanese. I translate them in English for you. IBM support pages also say almost same thing such as http://www-1.ibm.com/servlet/support/manager?rt=0&rs=0&org=psg&doc=E2AB5DFBFCE082E685256512005C419B ---- Notes on power management features when PC cards are used Some of the PC cards might case problems on ThinkPad by combination of AC/DC and power management modes. PC card support software prevent this by doing special process when power state change. [snip] Type of PC card Suspend request(Fn+F4) Hibernation(Fn+F12) AC DC AC DC Modem, NIC OK (*) OK NG OK Others OK OK OK OK *: However the machine enters in standby, not suspend. ---- I wonder if older releases have a special hack for this...

This seems originally came from CONFIG_APM_ALLOW_INTS in linux. Thanks To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
