See http://h10025.www1.hp.com/ewfrf/wc/genericDocument?lc=3Den&cc=3Dau&dlc=3Den= &docname=3Dc01296338 for more details. Since it's already had the motherboard replaced (with symptoms matching those listed), I thought it prudent to upgrade. Unfortunately, after updating the BIOS, the laptop no longer likes losing mains power: It looks like the clock interrupts stop so nothing happens unless you generate keyboard/mouse/network activity. This situation continues until it's rebooted. This looks very much like the 'C1E mode disables LAPIC timer on idle' bug that was stomped on last April - but it seems that HP have managed to find a way around the bugfix. The laptop is running 6.3-PRERELEASE/amd64. Any suggestions on how to start investigating? --=20 Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour. --gKMricLos+KVdGMg Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.8 (FreeBSD) iEYEARECAAYFAkgVtF8ACgkQ/opHv/APuIfDjACfVyLT3WgD+IeAqoYnA5bSwAmG SNcAoIMEKfwsSnvaeNoJrie0wJQuTfNS =QqzA -----END PGP SIGNATURE----- --gKMricLos+KVdGMg--
