Off-Topic: use laptop only as USB power supply
-----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-----
Get a minty boost from LadyAda and use batteries. Much lighter than carrying a laptop as a big battery around. :) http://www.ladyada.net/make/mintyboost/ -Gabriel Matthias Flittner 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:

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:

If you're looking at one of these, just be aware that they are 110 volts only. Scott.

Toshiba netbooks also have a (bios-enabled) USB charging port (and a netbook's something you might be lugging around anyway?)

My last Lenovo laptop had a setting in the BIOS for exactly that. Worked great for hotel rooms (which notoriously have very few power plugs) when I wanted to charge my cell phone and other devices over night. No clue about other vendors.

I only need voltage on the USB ports.
Voltage won't be a problem .. current will be. By default, USB supplies 100ma of power. To switch into "high-power" mode (500ma) requires the device and the host agree on doing so. If you're at all handy with a soldering iron, this is a fun project to do what you need : http://www.ladyada.net/make/mintyboost/ There are also any number of commercial devices that can do universal voltage (100-250v 50/60hz) to 5v USB that are barely larger than a matchbook.

Tekkeon's TekCharge MP1550 is a beefier version of this; it will work with two or four AA batteries, and provides USB. If you put rechargeables in, it can also charge them via a secondary charging port. This has become my solution of choice for backup power for power-hungry cell phones that drain their batteries every other day. The flexibility of being able to stop at any store and buy a pack of AA batteries in a crisis is great. For me, it's passed the pocket-indestructability test of having survived more than three months unprotected in my pocket, which typically does plastic thingies in. ...
