HP/Compaq :: DM3T Screen Dimming Randomly
Nov 10, 2009
I just got a HP DM3T and so far it is great, except for one thing. For some reason when on battery power the brightness seems to randomly darken (not turn off) and then it will lighten back up when I go to a different program or page. I am sure this is some sort of power saving feature but it is driving me crazy. Is there any way to disable this feature so when on battery the screen stays the same brightness? I apologize if this issue has been covered already, I must not be searching with the right terms. . .

I have an HP Compaq 8510p, T7300, running Windows XP Pro. In the last day or so I noticed that pressing the fn+Fx key combos to dim or brighten the screen are no longer working. Nor is the battery status key combo. Volume and mute seem fine. Wireless is fine. The "Info" and "Presentation" keys as well as the sleep combo all appear to be working as usual. But the 3 mentioned above have stopped working. Has anyone had this issue or have any idea what the problem might be?

Does anyone's screen dim itself every now and then? I don't know if it's a defect in the screen or maybe a bug in Quickset or something else, but occasionally my screen just dims a few levels.
Quickset shows it still maxed out and lowering it a notch and raising it back up using the keyboard shortcuts makes it go back to normal.

These laptops are equipped with the CULV processors from Intel. However, the highest processor upgrade option, the Intel(R) Core(TM)2 Duo Processor SP9300 (2.26GHz, 6M Cache) does not appear to be a CULV. According to Intel's website, it runs on 25 volts, rather than the 10 volts the other processors for this laptop run on. Considering that battery life is one of the primary reasons for me purchasing this laptop,I am concerned as to how that will effect battery life. Could someone shed some light on this issue?
Portability and battery life is a necessity. However, I am concerned that the Intel(R) Core(TM)2 Duo Processor SU7300(1.3GHz,3M Cache) will not be enough processor to be used as my primary computer. I do not demand a lot from my computer; I typically run several tabs in Google Chrome and run Microsoft Word simultaneously. Occasionally, I also use websites like Hulu that would demand more of a processor. My main concern is this laptops ability to be my primary computer and its longevity due to the smaller processor.

I've had my M1530 for about 5 months and in the last few days and have had a problem with the screen.
Twice in the last 3-4 days I have come home from work to find the left hand side of the screen substantially dimme(darker.
The screen was left on regular settings, no screen saver etc. Within 5 minutes of use the left hand side of the screen had returned to normal brightness..

I recently ordered a dm3t with pretty much all the upgrades during one of the sales.
Pretty much the same day I did that, the probook 4320s showed up on their website.
I'm trying to decide if I should return the dm3t and order one of the probooks. Right now the probook doesn't offer the discreet 512mb graphics card or 64 bit OS as choice but the customer support people say it will become available soon.
Basically I just dont know if it's worth the extra money for things like a better cpu, gpu, DVD, and fingerprint scanner.

Just picked up this model from Best Buy yesterday. Like everyone else in the large thread I am having the yellow color issue as well. However, I have another issue that I can't seem to find any information on.
Â
The brightness on my screen is constantly adjusting. It is most obvious when making the move from the desktop to Metro. After hitting the windows key, I can see the brightness increasing in stages (about 4 times) after flipping over to Metro.
Â
I have disabled Auto-Brightness under the Change My PC Setting -> Power and Sleep menu. I have also disabled Enable Adpative Brightness under Windows Power Mangement but the issue still persists.
Â
Is there any other location I might be missing a setting that can be affecting this ? Brightness is set to full and keeps dipping down.

I have the following set-up on my DM3T that is getting 4.5-5 hours of battery life at a maximum with light use, ie: lowest screen brightness, wifi off, word processing. I am not running any background programs (anti-virus) or anything else that is resource intensive.
SU4100 1.3ghz 2MB L2 cache
4gb DDR3 ram
320gb 5400rpm HD
Why am I getting less than 5 hours of battery life on a unit with low specs that is supposed to get "up to" 10 hours?? Is this consistent with what everyone else is getting? Battery bar currently says that my battery's 'full lifetime' is 4:58. I just returned an Acer timeline that had the same processor and 3gb of ram instead of 4, and that thing was getting 8-10 hours easily.

Prior to 2006, there was a distinct difference between Apple and the PC industry. Apple specialized in design, and still does, and the PC industry won over customers by wooing them with the best bargain available—features for the price charged—and almost always at the cost of a pedestrian design. In 2006, in an ambitious bid to gain market share, HP launched a massive and hugely successful marketing campaign known as, “The Computer Is Personal Again,” and redesigned all of its laptops with the extremely popular high-gloss Imprint finish. In less than 2 years, HP unseated Dell as the undisputed leader in PC shipments and maintains that lead today.
3 years later, HP is back again (perhaps) to change the game. Borrowing from design cues from Apple’s Macbook Pro line, HP launched the dm3 in late October and the tm2 earlier this month, with designs that feature a brushed aluminum finish. Is it successful? Read more to find out.
How this laptop was purchased
I had shopped for a while to look for a new computer to replace my aging dv6000t from back in the Windows XP days. My options were the HP Pavilion dm3t and the Sony VAIO CW. I visited a Best Buy to check out some of the laptops, and I can say that I was absolutely repulsed by the build quality of the Dells these days. They suck. Period. What really won me over from the Sony CW was the build quality of the dm3t. The aluminum finish really is outstanding. More on that later................

my friend is thinking about purchasing a new laptop for his mother. The HP DM3 laptops look to the best solution so far since they are both lightweight and have great battery life, something he thinks she'll appreciate. One thing i'm not sure about is their ability to run Adobe Photoshop CS4 smoothly.
I don't use Photoshop very often and when I do, it's on my laptop, which is pretty decent in terms of specifications. Will the program run fine on a laptop with a Intel CULV or AMD Neo processor and integrated graphics? Which leads me to my next question:
Which Pavilion laptop would you recommend? Are they both similar to each other than the processors?

I have a Dell XPS M1330 and have tried to find a solution for a screen that just doesn't want to stay at it's brightest setting.
I have adjusted all Battery profiles (including the "on battery" setting) and the screen seems to adjust to lowest background light settings every time I close the lid to my laptop.
I have adjusted all known settings for this, and still no resolution to the problem! Every time I close the lid to my laptop, windows makes a dis-connect sound (notification), you know, the sound it makes when you dis-connect a thumb drive or other USB connection.

for the past 3 days my Acer 8920G has been acting..very strange. It randomly turns off/has a blue screen, then I can't use it for 6-10 hours before it works again, but then only for 30 min then repeats. I've checked the temperatures for the HDD/CPU/GPU on the time I was on, and the HDD was 58C, CPU and GPU were around 50C (With FF3.5, iTunes, MSN and Vuze running). I've taken off the back panel and removed the dust but that didn't do anything at all. This morning I turned it on after leaving it upside down (back panel on) to vent all the air (if I left it open more dust would've gone in) and it wouldn't even hit the desktop. Kept crashing when it hits the desktop (that's basically what happens when I try and turn it on after it has a blue screen or turns off). So I opened the back panel and let my hand hover over the components - no heat what so evr radiated from it, which means it can't have overheated...right? Now I can only run it with the back panel off, which I'm doing now in a well ventilated area.

The screen is randomly glitching, when i'm watching videos mostly, but also using chrome and sometimes in certain videogames. They are not longer than a second, and appear randomly, mostly with 5 seconds to a few minutes of time between them. They are no more than 200 px of width, some times smaller. I have the feeling that they are getting worse each day. I'm not able right now to update my drivers for the GPU because of my internet, but when i'm able i will.

I have a dell M5010 laptop. There was a problem with the screen of my laptop (diagonal lines coming when i opened "my computer" window) for which the dell support replaced my screen while my laptop was under warranty. The screen was replaced in the month of february 2013 and my warranty expired on 3rd of March 2013. Now after two months of my screen replacement i am experiencing white outs which is quite random and happens at start up as well as while i am working on my laptop. After the white screen remains for a few seconds the screen comes back with vertical line transition.
This particular model  of dell had lots of problem from the very beginning and had been a sort of bad luck for me. At first the hard disk along with optical drive was replaced and then the screen. And now the screen still after replacement is showing new defects.

Whenever I am charging my laptop and using it, the screen lights up to the highest brightness (I keep it pretty low most of the time). This often leads to my mouse freezing, and then I have to shut off my laptop completely. I'm using a HP 2000 Notebook PC, with Windows 8.1 64-bit.

 I recently started having some trouble with my laptop, the screen wouldn't come on during powerup, fans and hard drive sounded to be running.  This has happened 3 times since it started a few days ago.  I was able to get the screen on by plugging in my parents old monitor into the serial port, it just popped up in the same instant I plugged it in.  I have also had my usb ports stop functioning.
Â
On a forum somewhere that I cant find again, people with similar problems were told to take the back off the laptop and hit some sort of reset button on the motherboard. Â Should I try this? Â How can I find it?

I just got a thinkpad yoga and I have noticed since I started using it that the screen randomly flickers. I can't narrow it down to a time where I'm doing a specific task.

I have a w520 that is out of warranty. From time to time, the screen just turns off while I'm using it (no, not a dimming/screen off during idle isse). Everything else works perfectly though. I have to shake the laptop (lol, seriously...) and the screen comes back on! It's been getting more and more frequent. What gives? Is this a known issue? Is there some loose connection somewhere inside? What should I check?

Recently started having a problem with the mouse pointer randomly jumping all over the screen. It's gotten so bad that I can't even use the computer at this time because the pointer won't stay in the same place long enough for me to type or select anything. I typically use the laptop in the screen forward configuration so I don't use the touch pad and nothing is touching it. I use the touchscreen about half the time and use an external USB mouse the rest of the time. It makes no difference which method I use or whether the external mouse is connected or not. as my fancy 4-month old laptop is essentially useless at this point.

I have an X220 convertable laptop but the mouse cursor is driving me mad. Â It randomly jumps around the screen; clicks things and generally makes working really hard. Â
Â
At first i thought i might have a virus although i have Norton installed. Â I have done virus scans with Norton and McAfee in both regular and safe modes. No problems found.I have diabled and installed drivers; changed mouse settings; reistalled USB drivers; tried a corded mouse and nomouse other than the touchpad. Â Nothing works.Lenovo support say they think it is a hardware problem; they sent me a new keyboard. Â i put the new keyboard in (really easy to do). Â No difference.Lenovo want me to return my machine for evaluation but i use it every day..I make mony on my computer and cannot affort to lose it for the minimum 4 days max 10 days they want it for service. Â If i cannot work for 4 days I might as well go and buy another computer and throw this one in the bin!

I have this massive problem with my cursor randomly moving and clicking all over the screen without being touched. I hadn't had this problem until after I had my cracked screen replaced with a new one. I've tried unplugging the mouse, disabling the touchpad, etc. and nothing.

Im a ENVY 17-j092nr Notebook PC (windows 8.1) pc user with all drivers and OS updates working fine, nevertheless sometimes im getting an annoying error that makes windows vibrate like crazy, the problem is a little odd to explain, it makes the BAR on explorer.exe folder flick and other "content frames" from several software, on Firefox for instance the upper bar which is orange start flicking useless, or in vlc it flicks the same, and then the worst on the windows log screen, that makes my picture flicks fast from the left to the middle several times per second, making impossible to write any password and its especially annoying when simple pass stop working.
Â
Thing that i tried:
-Changing mouse and installing video, display, mouse and other drivers besides updating them.
-Using Windows build and external software fix and repair utilities.
-Updating OS (Why? dk but i was trying alternatives).
-Disconnection electricity when this happens didn't work.
-Cleaning fan and avoiding any external particle on mouse laser.

I've only had my HP Elitebook 8530w for a few months now and is my first laptop. I love just about everything about it. However: Recently I have had problems with the screen going out on me every so often. It just randomly goes very dark, to the point where it looks like its off, but I can still see VERY slightly whatever I was working on before. Has anyone experienced this and possibly knows what could be going on? (it just did it again. 3 times in a one hour sitting)
Whatever anyone can suggest would be awesome. I'm not to savvy about laptop hardware and such, so i'm a little ignorant when it comes to troubleshooting this issue,
I forgot to mention. Here's some specs.
Core2 Duo T9550
15.4" WUXGA
GFX nVid FX770 512
RAM 4GB DDR2 2DM
HDD 250G at 7200rpm
standard 8 cell battery
