Brightness Tuning Not Working Properly On HP 6735s

Display Brightness Problem With HP 6735s
I've installed Windows 7 on my HP 6735s Notebook and everything works great. But I have a problem with the display brightness because if I trie to change it more brighter it does not work. The FN keys for the brightness also do not work and I don't know why. The others for the sound etc working normal. If I trie to change the brightness in power options it is impossible to change it more brighter. The only mode which works is the darkest even when I have plugged in the power supply.

NVIDIA Screen Brightness Vs Video Brightness
I am currently running Windows 7 RC1 and have noticed a behavioral change from XP which I would love to change.

In the NVIDIA control panel, there are 2 sets of settings for brightness:

1) Desktop color settings

2) Video color settings

In Windows XP, these would be completely independent. Thus for example, I could have my desktop dark while the videos could be bright and vivid.

Thus in XP:

Desktop Brightness = Desktop color settings

Video Brightness = Video color settings

In Windows 7, the OS only behaves this way when using Aero Basic. If I'm using the full Aero interface, I get the following behavior:

Desktop Brightness = Desktop color settings

Video Brightness = Desktop color settings + Video color settings

I would really love to have these control act independently on the full Aero interface. Is this possible? NVIDIA settings can obviously still distinguish the video because the video color settings still only apply to video, so I'm not sure why it behaves this way.

All Programs Not Working Properly
I am having problems with all the programs I have tried thus far. Both Firefox and IE crash after a couple of minutes use, as does iTunes, Windows Media Player and I also tried Elder Scrolls: Oblivion as well.  All 'stop working' and the computer returns to dektop.

I am running Windows 7 RC x64.

AMD X2 Not Reporting Or Working Properly
Ok, this is going to seem odd. Installed 7.7000 32 and have had no problems, until last night when I realized something was amiss. In the task manager, (and performance monitor) the system is only reporting one core. I installed amd's cpuinfo and it too says that there is only one processor (0) on the system.

To make matters more confusing, the Device Manager says there are indeed two instances of the AMD X2 5000+ Processors installed and working properly. I tried to do a quick "upgrade drivers online" but it just reported that everything was fine. AMD's website doesnt seem to have any drivers (other than for XP/2003 x64).

I thought 7 was supposed to handle mutlicore better, but am i missing something?

CD/DVD Drive Not Working Properly
Windows 7 seems to freeze and crash when I input a CD or a DVD in my Dual-Layer CD/DVD RW-drive. I've checked the drivers, which windows update says is up to date, and tried with lots of different CDs and DVDs, just to check if the disc in question was broken.

This is really problematic as I dont have a spare DVD drive anywhere. Anyone else had this problem? If so, how did you fix it/did you fix it?

Dvd Player Not Working Properly
I installed Windows 7 yesterday, and for some reason, my dvd player isn't working correctly.

I checked the drivers, and it says they are up to date. Not that I can find any for download anywhere though. I have a Sony Optiarc DVD-RW AD-7203S, if that helps.

This is what it says on the device manager, "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)". I don't think this is the doing of a virus, since I've scanned my computer twice and not found anything.

Is this something I can fix or do I need to install Vista again?

Start Search Programs And Files Not Working Properly
Its been happening ever since I installed Windows 7.

For example, When I click Start, type "CC" in the search box, the Start menu displays what I intend to start (CCleaner) but when I press enter I get this:

Its acting completely wierd!

On top of that, when I right click the entry, I get a menu which is expanded towards the left awkwardly.

I also recall that I have unchecked "Allow files on this drive to have contents indexed in addition to file properties." in the properties of my Windows 7 boot drive.

And since the programs are installed there, I think the problem might be related.

I have checked it again but it dosen't have any effect!

Dell USB Card Reader Not Working Properly
I have a Dell XPS Studio 435T that was running Vista Home Prem. 64 bit.

My card readers were labeled G:, H:, I:, and J: and were there when I got the machine. C: and D: are the Dell Vista Home Prem. 64 bit OS and the Dell Restore partition, E: and F: are my DVD drives. These drives always appear.

The system was built early May and was the A07 BIOS.

When I needed to read an SD card, I plugged the card into the proper slot, nothing happened? Discovered the drive was NOT on Explorer nor COMPUTER desktop icon when double clicked. I have a Canon printer with card slots, put the card in the printer after I turned it on and I can read the card, so it isn't the card (unless the 435T's slot can't read 8GB SD cards).

I don't get any errors when starting the system and nothing apparent in the Event Viewer.

I called Dell figuring they'd be aware of this problem and have a suggestion. Wrong, they claim it isn't a common problem and is either a h/w problem or I 'did something' to the system that caused this. Suggested fix was to restore the system to the shipped state and I was not too happy about that.

The Rep. then agreed to get on my system and look at it. I showed him the drives and the Device Manager that had an 'Unknown Device' and that it had no driver. I showed him that when I tried to update the drive it said I had the correct driver. I deleted that device and then had Device Manager search for changes and it found the same 'Unknown Device'.

Now the Rep. thought I had a driver problem and proceeded to re-load the Intel Chipset drivers. I think I did replace those with more recent ones, but I let him. It installed INSTANTLY and the rep. said it meant I had the drivers installed... Checked the drives again, not there.

Next step as for me to shut-off the system and restart into the BIOS screen and RESET the BIOS to the factory default. OK, but when the system booted, didn't do anything for the problem.

Now the Rep. asked if I could open the case and check the cables to the reader bar. This was after he came back on-line after checking what to do next. By this time I decided I wanted to try something, I have a USB single card reader. I put the SD card into it and inserted it into the card readers USB connector. It found the device, although it didn't assign a drive? Put that same device into the USB connectors behind it and it had the same results but the Rep. was now convinced I had power to the card reader and wouldn't need to open the case.

I then used a real USB Flash drive, put that in the card bar and it worked and could be read (and the Rep. wanted to connect and open the flash drive to be sure, which I allowed).

So, the Rep. wants to REPLACE the h/w. From the reports I've seen, this is a waste of time. His response was he's never seen other reports of this failure and my only other choice is to restore Vista to the shipped state. So I OK'ed the h/w replacement.

I know I've seen the drives as recently as 2 weeks ago. I was surprised one day when I opened Explorer and saw additional drives and then determined they were the card slots. As suddenly as they appeared, a few days later they were gone.

Dell eventually replaced the device, cable from motherboard to it, and even the motherboard. In all cases, replacing that component had the card slots reappear on boot, only to disappear sometime later.

This had been ongoing since July when I first discovered the problem.

Only after I installed Win7 was the true problem discovered.

I had a random BSOD under Vista with DVD Flick. Not often, but it happened. All I had to do was re-boot and it worked fine. Assumed it was a memory problem.

After installing Win7 and booting after a BSOD from DVD Flick Win7 reported a USB device was not working properly and showed a list of USB devices. The suggestion, unplug and re-plug the device and if it didn't fix it, replace the device. Well, looking in Explorer, the card slots were gone. Unplugged the cable and put them back in (case had to be opened to do this) and booted, problem was gone.

I've since removed DVD Flick and the problem has not come back.

So, the question is why wasn't the USB port working properly? I assume an initialization problem, and I see a HOTFIX was just released for Nvidia systems with 4GB's of memory and USB devices stop working so I wonder if the USB drivers could be at fault here?

ATI Mobility Xpress 200M Drivers Not Working Properly
I have an Acer Aspire 3650 laptop with an ATI Mobility Xpress 200M integrated video card. When Windows 7 automatically update the video drivers and reboot the system, I don't get video signal. I can connect my laptop to a LCD screen and get video, but at a very high resolution (something about 1440x???)

so I guess the drivers set my screen resolution too high to get any image on my screen. I tried changing the resoltion using that LCD screen but even setting it to 800x600 doesn't make my laptop screen to work. BTW, ATI beta drivers package doesn't seem to work...
Any ideas?

Brightness Problem On Laptop
So I noticed that every time Windows 7 loads and I'm using my battery then plug into my AC adapter the brightness won't get brighter, I have to manually go into power options and drag the little indicator bar. I want it when on the AC adapter to have a full bright screen and when on the battery 50%. Well Windows 7 doesn't want to seem to remember that because after every boot both the battery and ac adapter will have brightness settings at 50%.

This is a Windows 7 problem and I was wondering if anyone has a solution.

DELL 1420 Laptop Brightness
I somehow experiencing dim brightness from my laptop: DELL Inspiron .

I've tried in Control Panel: Power Options

I am using Balance (Recommended) but still compare to previous (Vista) the brightness is far brighter than Windows 7. Anyway to solve this issue?  

When I am charging / plugging, it's brighter.

When I unplug, it becomes dim. (I've tried Fn: Up) but still it's like only half of my brightness when I am plugged.

I suspect it has something to do with my Driver Tools because after Clean Installation of Windows 7, it couldn't re-install my Driver Tools as it didn't support Windows 7 yet. It only has OS: Vista in selection of OS System.

Brightness Controls Don't Work
I have a bit of a problem with my Windows 7 install on an MSI VR321 laptop. It's got a VIA C7M 1.6GHz processor, 1.5GB RAM and graphics are handled by VIA Chrome 9 HC IGP.

Automatically installed drivers didn't work well at all: screen would flick on and off when changing programs or rolling over programs in the bottom taskbar, and brightness controls wouldn't work.

So I downloaded and installed the latest graphics drivers from the VIA website (designed for Vista). Performance is much better, but the problem remains that I can't adjust the brightness. If it were a desktop this wouldn't be an issue, but for something running off a battery you can understand why this is a problem.

Neither the keyboard shortcuts nor the brightness slider bar in the display properties will work.

Not sure what to try next.

Does anyone have any ideas or has  anyone had a similar experience?

I was previously running Windows XP, but formatted and did a clean install before putting Windows 7 RC on.

Low Brightness Screen When Exiting Hibernating Mode
I installed Windows 7 this week on my notebook Dell XPS M1710.

Everything is good working, except one thing :

When I close the screen, so the notebook go hibernating, and then I reopen it, the notebook leave the hibernating mode, and here the screen goes dark, the brightness is very low, despite the brightness setting is at max. The only solution is to reboot the notebook.

So now I can't use hibernating mode, I have to always shutdown the notebook.

Does anybody have the same problem ?

Computer Not Shutting Down Properly
I have a dual boot computer running Vista Ultimate and Windows 7 RC.

I recently built a new computer for my wife and loaded it with just Windows 7 RC pending delivery of the full retail version in October.

Both computers have a similar problem. Sometimes - but not always - after shutting down the computer using the Start>Shut Down button it appears to shut down but has actually gone into a deep sleep with a blank black monitor and will not wake up no matter what keyboard buttons you press. It will also not reboot when you hit the computer power button.

The only way you can switch the computer off is to hold the computer power button down for about 10 seconds - then press it again for a normal reboot.
