HP/Compaq :: 8510p Has Lost Screen Dimming/brightening Functions
Aug 15, 2009
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?
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 just received from ebay a nvidia Quadro 770M 512MB Quote:

as an upgrade for my HP 8510p which currently has ATi HD2600 256MB.
Both cards are MXM II (physically fit) however I'm afraid that this VGA is not on whitelist so it's not going to work - I only get blank screen, no error message, no POST, no chance of entering BIOS. I read that there is some tool that can modify BIOS - something called HP Tattoo utility however maybe it's obsolete now and has been replaced by some other utility - I can't even download it anywhere.
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.
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..
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.
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.
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.
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.
Will a drive with this specs work on my machine? I have the latest bios revision? Will it work perfectly fine if i just swap and install a fresh copy of Windows 7? Also which is the best drive to get? I am thinking of the Seagate Momentus 500gb.
I have this 8510p with the 1680x1050 screen. Its been a great computer, and have only had it for about 5 months.
All of a sudden one day weird characters fill the screen on boot up between the bios start up and windows start up. Basically the screen is filled with 8-10 characters then a space, repeated over and over again. Some of the characters randomly change. And now I have a dotted line of red pixels flashing on the top of my screen. the line is about 20 pixels high and about an inch from the top of the screen.
More weirdly is that the flashing is happening in time to any activity on the computer. I am a network engineer and have worked my way up through small computer support but I have never seen anything like this before.
So when the computer is totally inactive the screen is great.
Is the inventor in the screen going bad? Or is it my installation of vista 64?
I don't think its the windows installation because I can see some weird video characters before windows even starts up. I have tried to reinstall the video drivers and most of the other drivers with no effect.
I'm using my 8510p. I was smart enough to buy an extended warranty, and it has proven to be quite usefull. (2 screen repairs and a new GPU.)
Now, over the time I have upgraded my notebook. The main HDD was upgraded with a 640GB drive, and I replaced my DVD/CD drive with a special bracket that allows you to install an extra Hard drive. Until so far, all these upgrades could easily be reversed for warranty purposes.
Now, I'm thinking about upgrading my original WSXGA+ screen with a WUXGA screen. (1680x1050 to 1920x1200) As since I'm using my computer a lot for graphical applications and CAD related stuff.
Now, I found a supplier that can supply me the screen, but he only recommends me to change my screen with something of the same resolution. He fears that the inverter may not be able to pull the higher resolution, nor my motherboard/gpu fail to recognize the new part.
Do you guy's think that this upgrade could be possible?
Personnaly I would go for it, since the 8510p was offered with a WUXGA screen, and the CCFL of the new screen would be exactly the same as the (current) WSXGA+ screen.
i have a hp 8510p business notebook (gb967ea#akn) with a mobility radeon hd2600 - 256mb, winxp pro sp3 32bit. cpu intel core 2 duo t9300 2,5ghz, 4gb ram (2x2048mb kingston ddr2 800mhz).
i use original ati (desktop) drivers by adding "ATI Mobility Radeon HD 2600" = ati2mtag_RV630, PCIVEN_1002&DEV_9581 to the cn_####.inf file of the driver (currently 9.2) and installing ccc afterwards. this assures me best possible performance (eg. ca. 100-200 points higher 3dmark06 score than other people get with the same notebook) and no errors/problems until now.
now i have 2 questions.. first regarding hypermemory, which should be 512mb according to hp. ccc, sysinfo, siw from gotpala.com etc. all say my hd2600 has 256mb. Internal DAC 400mhz. ccc says core clock 500mhz, memory clock 600mhz. i heard people saying ccc showing total possible memory (= dedicated AND hypermemory) as memory size on their notebooks........
since i experienced some major problems last weekend on my 8510p gb967ea win xp pro sp3 notebook, i am forced to reinstall the os and i thought this would be a good chance to replace the 5400rpm 160gb drive (sata), especially in order to try out win7 on a big enough partition.
now i called hp and they told me that the maximum possbile would be a 250gb 5400rpm drive or a 200gb 7200rpm drive (which is set inside bios). i definitely would upgrade to a 7200 rpm (if not to a velociraptor or an ssd), but for just a 40gb gain this wouldnt really be worth it, as i will get the new 8540p notebook as soon as they are released with windows 7 and some satisfying hardware (dx11 gpu!), if they get this hardware, which i hope..
so does anyone know whether i should try a bigger drive (i would go for at least a 250gb 7200rpm drive, better 320gb or 500gb) and maybe check compatibility while in the store in order to give it back if it doesnt work, or leave the 160gb 5400rpm drive and wait for the new models?
or is there any way to extend the compatibility restricted inside bios (using the most recent ver. f.15/dec 08 now)?
around a month ago i spilled some iced tea in my laptop. first i thought it was gone, but then i dried it out and it mostly works. i turned it on within the 24 hour period, but it mostly works.
it boots up and i can install the OS. problem is that whenever i move the touchpad it's like the left mouse button is always clicked and it's a constant select on everything i scroll over. i tried replacing the touchpad and using only a USB mouse but it doesn't work.
new touchpad does the same thing and USB mouse won't work in the OS. it will work during installing the OS, but once in the OS it stops working.
if it was possible to get the laptop to wake up when the lid is opened? Currently, you can put it to sleep by closing the lid, but when you open the lid you have to push the power button to wake it back up. I haven't seen any option in the power settings to do this either.
I need a new battery for my 8510p. Something very odd happened. I noticed that my battery has seemed to not last for very long these days. I saw HP's battery check software on their site and downloaded it. At the time I started the check, the battery was at 93%. The software determined that the battery needs to be replaced. The odd thing is that after I took the laptop off of the dock to check it's wireless connection, the battery charge plummeted (within a couple of minutes) to 11%, where it has remained ever since and refuses to charge beyond that. It's almost as though the software pushed it over the edge somehow.
I've noticed that my 8510p's HDD (which is a Toshiba) makes a loud scratching sound for about a second every week or every two weeks. I ran HD Tune's error scan and it came up with no damaged blocks. What's wrong? Should I be worried? I've already backed-up my important stuff.
I had to buy a replacement HP AC adapter because the original one stopped working. So I went out and bought the HP 90w AC/Auto/Air Smart Adapter (The box says 8510p is compatible).
When I plug in the laptop, the touchpad seems to go out of whack and jumps around at times. When I remove the AC power, the touchpad works perfectly.
There are a couple of differences written on the back of the adapters:
I have a HP 8510p (XP32) that works really fine. The only thing that I can not make it happen is that whatever I try I can not get the DD, DTS work between my laptop HDMI and my receive. I recieive only stereo (Audio HDMI OUT is selected).
Question: 1) How on earth can I get DTS/DD from my laptop HDMI when i play a mkv with DTS/DD audio?
2) If I connect the laptop to the TV via HDMI and the laptop to my amp via optical, can it make the trick? (the only problem here is that, my laptop does not have optical out, just HDMI and analog, but using a docking station i can have optical out...)
It first started when I was doing a light activity (word processing). What happened was both CPUs shot up to 100 percent and everything became horribly slow. Left/right Clicking on an item or the Start orb might take 30 seconds or longer before it would work. Task Manager showed 100 percent CPU usage under performances, but sorting by CPU processes, only 10-15 percent was being used.
I restarted, and to my surprise, instead of the nice under 1 minute load time to the desktop, to took at least 15 minutes where both CPUs were constantly at 100 percent. Safe mode was also very sluggish, where I stopped non-essential processes with msconfig. So I yanked my HDD and did a backup just so I wouldn't lose anything. After a few hours of the 8510p sitting, I put back the HDD and the machine worked perfectly for about an hour, then both CPUs shot up again to 100 percent. Once the issue happens, it occurs everytime I reboot regardless of how I boot into Windows. After being powered off for 4 or more hours (or overnight), It might work for an hour or so and then become horribly sluggish, or it might start out being sluggish, too. (BTW, no viruses)
So I got on the instant chat with HP support and told them about my issue. My tech had me switch out my 2 gigs of RAM with another laptop, but that didn't fix the loading issue. He said it needed to be sent in, so I received my box last Tuesday. On Wednesday, I got a call from HP saying my machine was fine and the only problem was my battery was dead and that would cost me 212 dollars (I don't know where they pulled that number, because a new battery on their website is 109). Great, the time it would actually work for an hour, it works perfectly there. I told them that I didn't need a new battery (I pretty much use it as a desktop at home), but that there was some other issue. She said she would email the "advanced" repair guys to look at my machine...
Due to what I thought were issues with SP1, I uninstalled it. Finding it not to be the case and that the uninstall left my machine somewhat "stuttery", I set it up for a system restore and went to bed. About eight hours later, I checked it and it was still restoring! I figured it had locked up (it's done this before) so I powered it off. Dumb move, I know.
Now, though, I try to start windows but it the screen gets stuck on black before it loads up the glowing windows logo. It will do the loading animation but that's it. I've tried loading Windows from CD but it doesn't make a difference. It loads the files with the DOS-like loading screen, then does the exact same thing.
I've also tried to get it to start in Safe Mode. I push the key to get there but the start-up selection screen only flashes before going right into loading Windows normally.
Please, I don't know what to do and I desperately need this machine to get anything done. It's just outside of warranty, so if there's any way for me to fix this myself I'd like to try.
Some things I've wondered about:
1) Is there a for sure way to get into the start-up selection screen? 2) Can I format the HDD with FDISK and then load windows from my vista cd and have it reinstall?
The brand new multitouch worked for 2 days while I was setting up the laptop and my files. I played with it for about an hour tonight. The X230T was running on battery, I plugged in the power cord, and the screen became totally unresponsive. As insensitive as a school bully in a bridal shower.
Per instructions at [URL] .... -- I'm running Windows 7, 64bit -- I uninstalled and reinstalled the ISD multitouch driver, 7wge69ww.exe. No go.
The only input device that now works is the mouse -- not the pen, not a finger.
Considering that my other X230 was sent to the shop last week (with a second dead motherboard in less than a year), I'm starting to wonder about Lenovo.
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.
