"Laptop makes a clink noise and is off"에 답변Sounds also a bit like a hard drive problem. The clink might be the hard drive stopping unexpectedly, maybe due to a connection problem with the drive to the motherboard. If I disconnect the power to one of the drives in my desktop it makes kind of a clink-ish sound. That's all I can think of. You might want to try re-seating the hard drive, or try one from another laptop if you have one, just to see if that is the problem.
"Turns on using Media Button not power button"에 답변I 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!

"How much would a screen cost to repair?"에 답변For the screen itself, there are different qualities of screens, and they cost different prices. I usually use Parts-People, they exclusively sell Dell parts, at a lower price than Dell will give it to you for. Here's a list of Dell Studio 15 screens from Parts-People.
