So, I suppose it's alright with the sound after all. What if the sound never goes away? I think I will give sotong168's suggestion a try.

hoho, it's quiet lar, i suppose "quiet" is a spin-down while "performance" makes hdd spin at full blast and thus faster but noisy?

Yup! that is why we can see HDD also got rpm ..some 5400rpm some higher..

the concept is same like cars. WHen you press the throttle(gas pedal) then rpm will rise.. the higher the rpm the more fast you go but the more noisy rite ?

so if u drive slow slow and rpm veri low ..veri smooth and quiet lo hehe ..

Laptop or 2.5" HDD comes with either 4xxx, 5400 or 7200 rpm. 7200rpm variant just becomes popular these few years back when mobile users demand for performance.

nice notebook anyways =)

It's well know issue with the high pitched noise.Waiting for Dell driver to fix it.

Is it hard disk or the pitched noise ? If hard disk , means your vista had finish indexing your file while if the high pitched noise stop means you are actually or overall running cpu usage 30% or more which trigger power status mode to C2 or even C1.

IMO , no need to waste $ on 7200rpm eventhough it's well in performance.The reason , SSD or solid state drive is coming in to the market next year.Performance is 100 times faster seeking time than any mechanical 10,000rpm hard disk.I forgotten where I read it before normal access time for a data using 7200rpm notebook HD would be around 15 to 20 ms but if SSD it's about 0.1 to 0.5 ms plus no noise when reading and writing data .Correct me if I am wrong

That's a very decent answer But I'm on XP from day 1. Didn't even boot into Vista, straight away format it to XP

Don't know where the pitched noise came, but now no more. Not even the hardisk spinning sound. Used to hear it for the first few days... or is it that my ears are immuned to it already

although SSD is suppose to have lower access time it still loses out in performance to normal hard disk le

No more users? If not then I'll pm the TS to update in the first post by tonight.

wan to ask why my 1520 automatic go in dell pre-boot system assessment
2 times in a week?
i thought under normal condition wont run the dell diagonstics automatically

how come my name not updated 1? my pink colour

God..my 1520 just BSOD'ed again last night.. It happened like 3 or 4 times before but i just wrote em off as random hardware errors but this is seriously starting to worry me..

Another thing, my wi-fi never resumes connectivity after i sleep or hibernate my laptop. bringing up the 'connect to a network' windows jus results in a blank white screen! And whenever i try to shutdown after that happens, the shutdown always freezes and i'd have to force-shutdown it. GRRR..this is really getting on my nerves... So much for all the hype on Vista/1520?

copy and paste and update urself dude.

hoho, the world is like this lar... u want something better u would have to compromise other thing; i.e. faster + better performance but heat-up + noisy

where is the HDD located anyway? that part should heat up quite significantly right?

HDD of Inspiron 1520 located next to the air vent, there is a "Strike Zone" label on it...
In fact I notice that the heat is distributed quite equally across the bottom, HDD is not particulary hotter than other areas. But the coolest portion is beneath the Optical Drive, (when you have no DVD spinning inside it of course)

my lappy is not hot at all...but it well get hot only when im doing heavy 3d rendering or playing games...the hot part is only locatred at the air vent and below the lcd hinge there...about the hdd area, i only feel the warm of it... btw,may i know whats the Strike Zone for?
