Turns on using Media Button not power button
I have reloaded the OS without the media portion of the Dell installation, but unlike my other studio 15, this one only "powers on" after touching the "media" button. The power key does nothing. It will not power the laptop off or turn it such as on my other studio laptop. The Bios is the same and OS installation is for Vista, no special selection are made during installation so why would this PC not use the power button? Mind you the Dell Media software is not installed. So it should not be in play...
the BIOS has a special setting for a "media function". This means you can listen to a CD without starting up the PC.
Maybe some settings were made in the BIOS so that the laptop only turns on when the media button is hit. You can try to set the BIOS settings to factory default.
I consider this more of a feature rather than a problem. For instance, I received a Dell Studio 15 from a friend that would not power on with the power button, seeing as the cord was internally ripped. It did however, boot with the media button once the battery was charged. Usually it was a combination of the network button and media button however.
Anyway, I'm not sure what started the media button power on, but if the power button does not power it on all I can think of is that the laptop recognizes the power button is malfunctioning and somehow allows you to power on with the media button.
I also know there is no setting in the BIOS that turns this on, so I also find it a little strange. You might want to try contacting Dell Support to see if they have a solution. Best of luck, if you find out what the issue is, please let us know!
The power button board is bad. That is a small, PC board behind the power button that connects to the motherboard. I have had to replace several of these. They are small, surface-mount boards with three wires on them that come loose with the slightest tug. Unfortunately, on my Studio 1558, the power button is up by the right hinge, which when opened and closed, flexes the wire for the power button board. You have to remove the top portion of the laptop (the palm rest bezel, the keyboard/speake
