i will check that out. under the load of a make world it should only take minutes to get the battery.life under 80%. many thanks for your hint. -- = = = http://michael-schuh.net/ = = = Projektmanagement - IT-Consulting - Professional Services IT Michael Schuh Postfach 10 21 52 66021 Saarbrücken phone: 0681/8319664 mobil: 0175/5616453 @: m i c h a e l . s c h u h @ g m a i l . c o m = = = Ust-ID: DE251072318 = = = _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
