HP ProBook 450 Display :: Constantly Dims And Brightens When Powered By Battery
Nov 3, 2014
my HP ProBook 450 lowers the brightness when its on a light screen (say the website background is white, it darkens the brightness) because white screens dont need the brightness ...and vice versa, it brightens the screen when its on a dark page.

My laptop is an Aspire V3-571-6447 with windows 8.1 os.For the past month or so it starts beeping and then the screen goes dim and then it beeps and brightens up again. This might go on for 3 or 4 minutes and then it stops. Is this an indication of a problem? It doesn't seem normal to me and from what research I have done it seems that beeping is not a good thing.

My T530 (a month old) is driving me crazy with this issue: Depending on which application is in the foreground, it will dim/undim the built-in screen (1600x900 version). I have turned off adaptive screen brightness in the power options, and I've turned off Film Mode Detection and Adaptive Contrast Enhancement in the Intel Graphics and Media Control Panel, but this "feature" won't go away.
How in the world can I get the screen to be on 100% brightness, unless I manually change it?

I've got a relatively new XPS 13. I noticed that I seem to lose battery charge even when I'm completely powered off -- about 10-15% overnight. Is this common or is something draining the battery that shouldn't?

My E530's battery drains 5% per day after power off. I searched online and somebody else complained about similar issue on his Y-series laptop. His problem was solved by plugging off power cord before turning off the laptop. Lenovo also updated BIOS regarding this issue for his model after then.
Yesterday I tried his way and the issue was gone too. Can Lenovo update BIOS regarding this issue?
I also find the power manage scheme doesn't work. It always charges the battery from 96% to 100% in whatever scheme I chose. I tried to uninstall the driver and downgrade the power manager, still doesn't work. I didn't try reinstall the system because it is too time consuming. Does it matter I installed win7 in my SSD?

I have a studio 1537 with the Ati graphics.
The problem i have is when i power on the laptop i get a warning saying Hit F1 Critical battery warning .
So i hit F1. Then get the option to hit F1 to continue or F2 to enter setup as battery cannot be identified.
So i hit F2 so in the bios i see not battery and it says NO charger detected.
Now my problem is the battery is totally flat if i pull the PSU the system dies . I have changes the power jack as i read the could give trouble.
What I could do next as other than this my machine is perfect. Just a note i also have two spare batterys one 6 cell and one 9 cell and still neither charge

My Dell inspiron 6400 has a battery that works amazingly but recently, I noticed a change in the behaviour. Anytime I switch the laptop on, the LED battery indicator shows me red meaning something is wrong even when the battery is fully charged. The battery charges normally even when I intentionally drain out the power and try charging it again. This is just to make sure that the battery charges fine. Infact, in windows, it shows me that the computer is on AC power even when it is not plugged into an AC outlet.
The BIOS shows "No battery installed" and windows tells me the same. Summarily, everything is fine except for the LED indicator showing Red and the BIOS telling me that no battery is installed.

I've recently bought an HP Probook430 and installed Windows 7 Ultimate 32bit and I don't seem to be able to change the display brightness, using the fn button+f9/f10 (although volume settings are changed in the same method smoothly).
Although the brightness settings don't seem to change, this bar does appear when pressing fn+f9/f10. What should I do in order to make the display brightness settings changable?

I have a problem with my Latitude E6430 i7-3720QM upgraded to Windows 8,, Bios A09, 8 core...Fan is constantly running and drying the battery out. Tem range between 60-70C. All tests from Dell webpage passed successfully. Tests from Intel Diagnostic tools passed. However, fun is always running, lap top is warm and battery goes down very quickly, in an hour. Under windows 7 it used to last much longer. I even did a clean install of Windows 8 and the problem persists

I just recently purchased the HP Probook 450 G1. The laptop doesn't come with any OS installed so I intalled windows 7 64-bit. After installing all drivers I see in Device manager screen that my Display Adapters are
AMD Radeon HD 8600/8700
Intel(R) HD Graphics 4600
but in the shop they said that my video adapter is AMD Radeon HD 8750M
My question is: are AMD Radeon HD 8600/8700 and AMD Radeon HD 8750M the same "things".
My hardware ID :
PCIVEN_1002&DEV_6600&SUBSYS_1947103C&REV_00PCIVEN_1002&DEV_6600
&SUBSYS_1947103CPCIVEN_1002&DEV_6600&CC_030000PCIVEN_1002&DEV_6600&CC_0300

In the hp.com configuration options for the ProBook 4710s, they show 3 options:
1. 17.3-inch diagonal LED-backlit HD+6 (1600 x 900) without camera
2. 17.3-inch diagonal LED-backlit HD+6 (1600 x 900) with camera (must select NQ004AV)
3. 17.3-inch diagonal LED-backlit HD+6 (1600 x 900) BrightView with camera (must select NQ004AV)
I thought LED-backlit was good enough, but option #3 is LED-backlit BRIGHTVIEW... Is this a brighter, "better" screen than option #1 or #2? I'm afraid of ordering this and getting another lemon of a "Brightview" screen like my dv7t screen.
What's "HD+6" ... what does "plus six" do for me ?
I don't see an "NQ004AV" option on the order page, either...
HP is just terrible at explaining these things.
Regarding the keyboard ... it's hard to tell from the pictures at Engadget whether this new chiclet keyboard is backlit or not ... HP doesn't say it is backlit, would be awesome if it was.

Model: HP Probook 4530s
OS: Windows 7
I have both Intel and ATI switchable graphics in my laptop. I recently reinstalled Windows & If I try to install the ATI drivers from the drivers CD or from the HP website, the laptop hangs on the Windows logo after a restart and I have to do a system restore to fix it. If I try to install just the Intel driver it just gives me an error that says "This computer does not meet the minimum requirement to install the software". I am unable to change the brightness and the resolution is bad. In Device manager both the options under display adapter say "Standard VGA Graphics Adapter", with a yellow error sign over one of them. I am worried if the graphics card is damaged from over heating. Is it possible to disable one of the cards to check functionality of the other?

I have seen it on two different laptops now. Both are HP ProBook 6460b. When the user plugs the laptop into a VGA cable that is connected to a projector, the laptop blue screens and reboots.
The laptop doesn't bluescreen and reboot when connected to monitors, but usually the users are using a docking station when connected to a monitor, or monitors. I haven't seen any issues with plugging in a VGA cable connected to a monitor, but that is rare.
I've tried updating drivers, but haven't had any luck.

Purchased Probook 4530S. Win 7. I keep having teh screen print/size resolutiom change when using the touchpad. The pointer seems to "stick" and then when I move it, the screen will either get very smaller or larger. I continually have to hit ctrl + or - to get the screen size back to "normal". Is this something to do with the touchpad settings or pointer?

I was watching a movie on Netflix, and all of the sudden the screen kept scrambling itself. I shut it down and now when I restart my laptop all I get is a white scrambled screen. I restarted it again and now I still can't do anything and it won't shut down unless I hold down the power button for a few seconds...

The past few weeks, when I start my computer up, in the top left corner the screen shows the words "Boot Error". It doesn't do this every time, though. I can easily get out of this by hitting any key and it starts right up.
also the past few weeks, when I shut this computer down, the battery charge light flashes at a regular rate till the computer shuts down.
What does that mean?
FYI, I don't have a battery in this notebook because it died about 5 months ago.
