Noisy Dell laptop

My XPS1330 is making some strange noises. It sounds like a high grinding, almost squeaky noise, "electrical crackle". It sounds somewhat like a searching harddisk does, only it is fainter and a little higher. Dell came and replaced my processor. The technician said he couldn't hear the sound, but that was because he's a bit deaf himself. This did not solve my problem, so I called Dell again. Now they say they can't do anything about it and they are going to close the case. They don't give me any other option! They don't want to change any other part or give me another laptop, because the technician said in his report that he couldn't make out the sound. But I DO hear it, and so do other people. If there is background noise, I don't hear it, but when the room around me is silent (the way I like it when I'm programming), the sound really bugs me. Other laptops do not make so much noise. It ain't the harddisk, I checked. It ain't the monitor, I plugged it off. It ain't the fan, it isn't running. BUT WHAT IS IT? I'm going to call the customer service monday, and hope to persuade them to exchange my laptop for another one.

XPS noise

My new XPS 1330 is functioning quite well, except for a few things. I'm running Ubuntu Hardy, and one really annoying thing is that sleep and hibernation are badly broken 'features'. The other really annoying thing is the noise the harddisk makes. It's a sort of high squeaking, grinding noise. It makes the same noise all the time, even when the disk is supposedly idle. I hope Dell will provide me with another disk soon, because it's driving me crazy. I'm looking forward to setting up all my linux desktop settings again. I'm rejoicing, really. [edit] It wasn't the harddisk after all. Even without harddisk and with an ubuntu live cd, the sound persisted. I called the Dell support and they said it could be the processor: some other Core2duo's experienced the same problems. The next workday, a guy is coming to replace the processor with a new one.
