With up to 40W of charging power plus that hardware then the PSU may be getting pushed close to its power limit. It relies on radiation / conduction to get rid of any heat.

My mistake, sorry, I thought you meant it was warm all the time.

Yeah, they'll get hot when charging since the current needed to overcome the impedance in the battery (this increases depending on how run-down your battery is) is much greater than the current required to run the machine when the battery is fully charged. It shouldn't exceed 90w though, even if you're charging up whilst flogging the machine out to full CPU usage or whatever. I believe most PSUs have a thermal fuse or something, which will knock it out if it gets too hot, so if it's still working I wouldn't worry about it.

And being a plastic case, it's won't be fantastic at getting rid of heat since it's not such a great conductor (however that's by design so you can't get a short across the rail inside and the case, giving you nasty shocks ).

 

So, for the couple of folks that were tossing out some ideas about my extremely long wifi connecting issues after a reboot or fresh start, I've done a clean install of win7 w/ just the core hardware drivers (no control point or other Dell software). I see to have full functionality, keyboard backlighting, screen dimming, etc...just not the dell specific stuff.

Now it connects/reconnects instantly on reboot, fresh start, or coming out of sleep. So, problem solved! Thanks!

New problem though. As part of this exercise, I also upgraded my HD to a larger model (actually tried 2, a 320 and a 640, both the same WD line as the stock drive I got).

There is constant drive access on either of the larger drives that doesn't happen if I put the 160 back in an boot up. It's dead silent and the other 2 cause the fans to kick in in little puffs of air, almost on a regular cycle...drive access, fan puff, silent, drive access, fan puff, silent. It's really strange and worse it's REALLY annoying and definitely audible. Both the 320 and the 640 do this.

WD's response was that my mobo didn't support larger drives, contact Dell...so basically, a moron with level 1 tech support took my support case. Obviously that's not the case.

Any thoughts on this one?

Anybody with either a WD3200BEVT or WD6400BEVT installed that notices the same thing or not?

Running a 500GB hard drive here, no issues.

 

Has anyone ever heard their AC adapter buzzing?
The buzzing is from the Dell adapter itself, not the APC.

 

I have the 135W adapter I believe. No buzzing. Haven't put my ear to it though.

Got the i7-620M which is WAY more than I need. Is it possible to underclock the processor in the BIOS for better battery life?

 

Sadly OEM build computer doesn't allow one to play around with system clock speed. You can however find program for Windows, that can access such settings.

Windows 7 feature advance power saving features, with is also extendable via drivers. By default Windows 7 allows you to control Wireless power management, PCI-E link State, processor clock speed, and a few other things at a somewhat level (min, med, high.. some has a little bit more details). Additional drivers can be attached, which the Latitude E series provide with Dell Control Point, is allowing the system to cut the power off firewire port, optical drive, media card reader, and lower the screen refresh rate down to 40Hz instead of 60Hz on battery, to save power.
It's pretty cool to have, especially that XP did not have such a feature.
It's not voltage and clock regulation, but at least it's something.

If you picked the Nvidia solution, you can tweak the speed (lower it, or normal speed, or overclock) on demand in Windows, with Nvidia System Tool (visit Nvidia web site to download this add-on).
For me, I set it to minimum speed, and when I do anything that require the GPU, I just double click on a saved profile file and poof it's at normal speed, and if I play a game, I load my overclock profile (see signature, I have the E6400 laptop).

 

DisplayPort to HDMI audio stopt working after updating to
NVidia display driver v8.17.12.5729

Rollback to
NVidia display driver v8.16.11.8974
HDMI audio works again.
"Manage audio devices" I also see a plugged in Philips FTV-1 NVIDIA High Definition Audio when displayport to hdmi is connected.

So be warned when you update to the latest display driver!

Yes, you need to use Dell drivers to have it. Because, Dell adds the IDT audio drivers in the video card driver to enable this feature (audio pass through Display port).
