Every Mac laptop I have ever used has powered the USB ports whenever connected to AC or airline power, regardless of whether asleep or awake. Not sure if it will power USB ports when powered, but, shut down or not. Have not tested that. Owen On May 20, 2010, at 5:52 PM, Paul Timmins wrote:
I think the last dell business notebook I had my hands on has a bios setting that enables usb power when the laptop is off and plugged into the AC adapter. It's not on by default. If you have one, you may want to check. -Paul Matthias Flittner wrote:-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi there, I'm not sure if anyone out there has an answer to this insane question: But is it possible to use my laptop only has power supply via usb for my mobile phone. Yes you heard right: I don't want to boot an operating system I only want to charge my battery of my mobile phone. No fan should be powered on. I only need voltage on the USB ports. Any suggestions? ;) best regards, FliTTi -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJL9bR2AAoJEIZn8Rym6s4A1TgH+gNSd8TRW34dvzgS03uTHKvi iZ3f+nciMeaJSN7Pq9Eugi3pgGvljKArcCiEmlV95BIP1i6hJiDuO7sOp/xx4yeO n8/iW6FyPBv5pqjuyhuTjs4GuG7ar4lM6/y4sYPT++bf5fWfwxjonYnmZakw2IVa 3fdsHeOIoyD45lirthSXXmynl/UO4ajYEwI+dqs2vpYcUYTgBW4WhQ1zMnVKJasn PtpuMx1M3a3xF3rFZ6PZ2KmtVRQhjpgaU1TYZO2jcABoKS9e7s2j5zFR+0nhIqzK hq2mQWGlA49Lgt+P21jsaJ8YZxD4AvZFnDXg3flR/FFTVIfVcWoQELvnWwv9iqs= =k+ae -----END PGP SIGNATURE-----
