Updated to win7 with A02 and everything seems to be fine so far. Just wondering if anyone here has the vostro 1520 running win7 with bios A04? I noticed that on win7 the fan dosent come on as much as winvista did, with that being said im curios on how the fan performs in win7 with a04.
I received my Vostro 1520 with BIOS A04 and indeed the fan is on very often : on average when I do some web browsing on pages without animations, the fan is off for 3 minutes, afterwards it is on for 1 or 2 minute, and then the cycle starts again. Since I have a Intel P8600 with a TDP of 25W and an Intel X4500 graphics card, the laptop should not warm up that much . Actually, with Speedfan, I can see that the CPU core temperature is kept between 30 and 33 degrees Celsius, which is much lower than needed (but the left palm rest is nearly the same temperature as the room temperature).
I reflashed with BIOS A02 (by overriding the BIOS version check) and now the fan is never on anymore during web browsing and the CPU core temperature is kept lower than 37 degrees Celsius. The left palm rest is a bit warm (in the range of 30 degrees Celsius), which is not a annoyance.
I have Vista 64-bit for the moment (waiting for the Windows 7 64-bit update CD), and after reflashing to A02 I had the same problem as the original poster : the resume from sleep only gave me a black screen, and I had to force the power off + unplug the power cable to be able to restart the laptop.
But I found a workaround : in the BIOS, a selected "Reset to factory defaults" and now my resumes from sleep is working again !
I cross my fingers that the BIOS A02 will work fine with Windows 7 as well... so that I can keep it forever...
Did you try to reinstall the drivers? I have that problem with a02 every now and then, it seems that everything is working but I get no audio, sometimes a reboot fix it or I have to reinstall the driver but this dosent happen often at all, maybe 5 times in 6months. another thing I noticed is if you boot up the laptop with the speakers on mute the audio may not work as well, just unmute them and reboot.
I have a02 with windows 7 and it works well, no problems at all.
Some more details about the fan :according to Lavalys Everest, the fan runs between 3000-3200 rpm, which is not slow and not quiet...
Dell, instead of changing the behaviour for everyone, only because a few complained of the warm left palm rest, please make it configurable for those who found it good (mainly those with an Intel graphics card probably).
jerrold14, thanks for your suggestions. I had already tried reinstalling the drivers but it did not fix the problem, I will try the other tips. When was your laptop built ? Mine is from December 09, I think I saw in the A04 release note that something changed with respect to audio, maybe to support new hardware ?

Hello,

I hope this tip can also fix the problem for you.

Hello,
There is one drawback when reflashing to A02 : the internal speakers do not work anymore, although the headphones do work when plugged in... Too bad !
