I noticed some strange things are going inside my Inspiron Laptop. I´ve read other threads concerning "Clicking Noises" in this forum but no thread describes what my Inspiron does.
Now to the problem itself:
About ten minutes after powering on my laptop a strange periodically clicking noise (sounds metallic - like some metal bursts because of temperature) appears and the strange thing is even if i shutdown the system, remove the battery and the ac power cord the clicking noise remains there for over half an hour. It´s no very fast clicking, it appears periodically every minute or so.
I then also tried to remove the hdd from the Inspiron but even with the hdd removed the clicking noise is there.
I´ve no idea where the problem is located. Has anybody had such a problem with his Inspiron?
Here my system specs:
Dell Inspiron 5150
Mobile P4 3,06 GHz
512 MB DDR-RAM
Hitachi Travelmate 60 GB / 4200 UPM HDD
2x DVD+RW/32xCD-RW/16xDVD-ROM (Combo Drive)
Nvidia Geforce FX 5200 Go
Sigmatel AC´97 Sound
Dell Truemobile 1300 WLAN MiniPCI Card
Broadcom 440x integrated 10/100 MBit Network Controller
BIOS Revision A29
Windows XP Pro
Hope someone could help me to get rid of this noise.

Maybe it is coming from the cpu ... my 5150 cpu makes more like a "buzzing" sound, but only when it is on.'
I agree with the statment that some residual capacitance may be powering some components. My guess is your sound may be related to the audio system or motherboard.
