Hello,
Well here's my problem. I came home from work one evening and tried to get on the internet with my HP Pavillion dv9000 running Vista, when I clicked to dial there was a hum on the speakers as the computer dialed the number, you could still hear the number tones as the number was dialed as normal. I've had trouble with my phone line before so I called the phone company to check the line it is OK. I also took my laptop to another house several miles away and got the same response. When I try to dial the internet it does dial the numbers but that's as far as it goes it will not connect. Now here's the strange thing to me anyway, if I unplug the power supply the hum goes away as the internet is dialed and I can connect to the internet just fine, as I type this thread I'm connected from my home on battery power only. So I thought well I need a new power supply, something has happened to the power supply and it no longer provides a clean supply of power. I purchased a new power supply off Ebay and as luck would have it when I received the new power supply did not work I checked the the output with a digital OHM meter for voltage and got no voltage, zero but here's the kicker if I plug in the new power supply (defective) I get the same results- the hum and can't connect to the internet. The laptop seems to work fine otherwise and the original power supply does charge the battery. Also if I take the battery out of the laptop and plug the original power supply into the laptop I get the same results- hum and can't connect to the internet. As long as I don't try to connect to the internet I can use the laptop with the original power supply plugged in and it charges the battery and there is no hum. Any Ideas? Sorry for long post. Thanks in advance.
