Re: charging phone on usb harmful?

The one thing to worry about is overloading the USB power feed. This is especially a problem if you are using a USB hub. If you are charging your phone using a USB hub, you should almost CERTAINLY attach a 5Volt external adapter to the hub. (most hubs have a plug for 5V DC in, but few of them actually come with the adapter). You can get the adapter from Radio Shack / The Source or any of a number of electronics stores. You can also use the old 5V adapter from an old hub or ZIP drive (just check the adapter to make sure that it's 5V DC). That having been said, the more likely cause of your RTC not working is that the CMOS battery has died / is dying. If your computer is more than a couple of years old, this is a possibility. Look on the motherboard for the battery (usually it's a silver button battery about the size of a quarter .. sometimes it can take other forms. It should be possible to pop it out ane replace it. It's relatively rare for the battery to be soldered in, but I've seen it once or twice. If you're replacing the battery: 1) make sure the machine is off, and 2) write down any wierd BIOS settings in case you lose your CMOS memory during the change.
