Dell :: E4300 Win7 64bit Backlight Control
Sep 30, 2009
I've got brand new Latitude E4300 and I decided to install Win7 64bit in order not to upgrade after I install all my software onto Vista. But I cannot get the LCD backlight control get to work.
In BIOS the settings work well, but in Win7 it does not. e.g. when I set in the BIOS half backlight, it works until I try to change it in Windows - it suddenly jumps to full backlight (I suppose),
but the Dell Controll Point dialog shows some 1/3 or similar. Then I'm able to change it +1 step, but it doesnt make any difference, even turning on and off the ambient light sensor doesnt make difference.
I tred to install several drivers from dell.com, but the support for Win7 64bit isnt very good. So I took some drivers from Vista 64b, and Vista 32b, but it made no difference.

I just noticed that my dvdrw is not working.
In My Computer it shows: BD-ROM
In Device Manager it shows: UNSBGH QBWHEN8X2305 (Drive Name)
The Actual Drive: TS-U633A
Has anyone experienced this problem? I try updating the firmware from U633A-U633C but it wont update and detect the "actual drive".

I was wondering what folks are doing for the Webcam and Ambient Light Sensor?
Do these things work properly after a Win7 install (without Dell Drivers) or are you guys using the Vista Drivers off Dell's site for these two things

the keyboard backlight goes off after about 30 seconds of non-use of the keys. The trackpad movement doesn't keep it lit.
i can re-light by touching any key, but this presents two issues:
1.) the first keystroke is entered. (i guess i can use the shift key)
2.) more important, the screen brightness seems to react to ambient light, so the keyboard's light ends up making the screen pulsate.
I couldn't find a specific reference, although hard to believe. But then again, the humongous threads are hard to search effectively.

Has anyone had an issue where the ALS suddenly stops working under Windows 7? I've checked BIOS settings, tried seemingly every combination of driver uninstalls/reinstalls, confirmed that both the Dell and Microsoft ambient light sensor services are enabled and running (and tried disabling, one, the other, and both) and have not had any luck. Unlike some other posts I found on here with the same-body Lattitude models, I can control the backlight manually with both the keyboard and software - it is only the ambient sensor that does not work.
I am running BIOS A15, and Windows 7 x64 RTM.

I running a z690 with win7, and my blu ray drive isn't visibile, don't have the correct driver for the Mata bd-mlt uj232as, and the z590 driver from sony's site won't install because its not a z5-series. Any advice? or anyone have the driver from there Vista64bit?
If anyone is curious, Windows7 is really smooth and quick compared to the Vista64bit, and only running 60 processes after everything got installed.

SZ Series Windows 7 Clean install (32bit and 64bit)
Primarily for the SZ750, but works most other SZ models.
Yes, it's long, but it overs a lot and makes it very, very simple.
A Note about the "new" Sony utilities on their website.
Don't bother, you end up with FAR less functionality than you will with this guide. Sony simply put up utilities that work with Windows7, they didn't check to see if there is a driver to allow them to work.

Status:
32bit 100% working – Use the Vista drivers and Utilities.
64bit 99.9-100% WWAN is possibly working (depends on the model, see below under “issues”)....................

1. How do I control the duration for which the backlight keyboard lights are on.
2. The ambient light detector keeps dimming and brightening my screen when in a complete dark room. How to fix this?
3. How to turn on or off the green power light button?

I want to put Win7 on my macbook pro and plan to use it with VMWare 3 as well as for dual booting. Is it better to go with the 32bit or the 64bit version of Win7.
Im running snow leopard on the macbook now... i know Apple isnt officially supporting win7 until later this year but has anyone else had any problems running Win7 under bootcamp on snow leopard?

I bought my lenovo G460 with nvidia M310 (with hdmi) this year and have not been able to get the hdmi port to work.
Â
I have two lcd displays one in our lab and another one at home (LG 2361V-PF) which have hdmi connections in the back.
In the beginning I was able to get my notebook to work on the display in our office. However, now both displays (work+home) are not working.
Â
I have tried to reinstall latest nvidia drivers as of 2010-11-02 (ver. 8.16.11.8990) from lenovo, completely restore Operating system and tried different hdmi cables.
Â
I have even tried to use original drivers and also downgrade that to a lower version all with no luck.
Â
I have even taken my LG LCD display to the LG After Service Warranty office and have found no issues wrong with the Monitor itself.
Â
I am sure I have taken all the trouble-shooting methods into consideration so a simple question is... Is the hdmi port defective?

I have an HP Envy j011dx that came with Windows 8 Home Edition(64b9t). I put in an SSD and upgraded the ram and installed Win 7 Pro(64bit). Everything is working great except the control keys don't work. When I hit the left ctrl, I get, [9- and the right ctrl, I get, l; I have searched and tried a few different drivers and have looked at some posts about downgrading to 7 and haven't seen anything on this issue. I have ran all windows updates and tried several different drivers. I put the old HD in with W8 and it works so it isn't a hardware issue. I originally looked at this post before doing the downgrade and it gave me the confidence to move forward with putting Win7 on. I have until Friday to take this back to the store if I can't get it working. I have also checked the region/language settings.

I received my Precision M4400 with Win 7 Pro x64 pre-installed, and using it for audio recording and playing everything works great. However, since Win7x64 drivers do not exist for some of my audio devices,
I decided to put in a new HD (same as the original, only larger) double-booting XPx86 and Win7x64. So I installed XP on one partition of the new HD and Win7x64 from the CD that shipped with the M4400. Big problem...
Neither XPx86 nor the re-installed Win7x64 are able to deliver anything but crackles and pops and noise only slightly resembling music. Forget about recording...

I broke my XPS M1330 at work and one of the laptops the computer dept is suggesting as a replacement is the Dell E4300.
I played around with one that my colleague has. The size of 4lbs is okay, the performance seems okay for my usage pattern. However, there's a major show-stopper: the screen. I'm none too impressed by the screen, in terms of contrast and black levels. This review confirmed my impression:
Notebookcheck: Review Dell Latitude E4300 Laptop ). And it seems this laptop does not offer any screen upgrade option.
Also resolution was okay, but I wouldnt mind a bit more, although that is not a deal breaker like the other two issues.
So is there any Latitude or corporate Dell unit that would basically be an E4300 with a better screen?

Windows 7 runs amazingly on this machine (specs in sig). Though, it ran fantastic with Vista as well.
Despite my overall good experience thus far, there are a few things to note:
1) The webcam. Yeah, it works fine with AIM and what not out of the box, but I'd like it if Dell released an official Win7 driver + Win7 Webcam Central to better support the Latitudes.
2) The Ambient Light Sensor. It's a bit wonky under Win7, so I've left it disabled for the time being and manually change the brightness when needed. Again, I'd like to see Dell release a Win7 version of the ALS Utility found under their Vista drivers.

I'm in the process of trying to decide between getting an E6400 or E4300 to replace my aging Toshiba A105-4074. I'm somewhat surprised by the lack of discussion here about the E4300 compared with the huge number of threads about the E6400.
I have an E4300 here at work that I have been impressed with, so I have hands-on experience with it. I haven't had any hands-on experience with the E6400, and have only seen one briefly. While I've read lots of good things about it, I wish I could use one for a couple of days in order to get a feel for it .....

I just received my E4300 from the Dell outlet, it's in great condition with one exception.
The keyboard has a bulge or slight rise in the center. I have the back-lit keyboard.

The Dell E4300 for example is generally inferior (IMO) to the Vaio Z (heavier, slower, uglier, lower quality screen, lower quality build materials, etc.) yet it costs just about the same."
Sony Z here in Canada: $2614 before tax ($45 shipping)
If you make the warranty the same (3 years), $2943 before tax + $45 shipping
Same specs, I paid $2100 before tax (and free shipping) for the Dell E4300. Is it worth the difference when the keyboard (I don't like the Z's keyboard)?
I have to wait the same week (Oct 14/15) to receive either.

Any idea if Dell will ever release an updated GPU driver to support Flash 10.1 hardware acceleration?
Currently the driver is 8.15.10.1855.
EDIT: Never mind. According to the Adobe release notes PDF, support starts with driver version 8.15.10.2021. Looks like we're outta luck until Dell releases a newer driver.

I'm interested in buying a good portable notebook and the E4300 is one of the main contenders because of the solid build, good batterly life and its weight and size
So I've been reading many mixed reviews about the latitude e4300 where many people thought it didn't live up to what you would expect from a premium business notebook with a premium price.

Curious what the main issues, complaints, etc. have been with the e4300 now that it's been out for a while. (Also, I'd love confirmation of it's actual weight.)
I was originally considering this the only potential competition to a Sony Z (as I am after light, slim but powerful/normal components). However, I've since backed off the idea of a e4300. Still

I need some advice on picking the E4300 or E6400. The pricing in my country is a little different from the US I guess. I'm stuck on deciding with which machine as the pricing is about the same (see below).
I'm studying in a university where my course is about 50% programming, and can spend about 5 to 8 hours a day in school....
