I have a Dell Inspiron 640m (e1405) that's recently started to make weird noises whenever the processor load is high. Here are the technical details:
Intel Core 2 Duo Processor T5500 (2MB/1.66GHz/667MHz)
2GB Shared Dual Channel DDR2 SDRAM 533MHZ,2 DIMM
Windows Vista Home Basic
The laptop makes two different sounds: a "crunch" and a "chirp," coming from what seems to be where my right palm rests when typing. Typically this happens when I'm doing things that require higher-than-normal processing power, such as watching YouTube videos with Photoshop open while downloading a torrent and writing an email in the nude.
I even recorded the sounds! Click here
to listen [.wav, ~700kb] to it. The first sound is what I call the "crunch," followed shortly thereafter by the "chirp."
The sound doesn't really bother me. I just want to find out if I should send this sucker back to Dell before my warranty expires, or if this is a normal-sounding sound.
