I am having a problem with my Pavilion dv6200
This is third time the same thing is happening to me. After i install some updates, display dimms, and background light became darker. When i restart computer, and enter BIOS, or if i am just looking at the screen before i log on to windows, backlight is normal.
my laptop screen backlight goes off, when I rest my hand on the left side of the touchpad. The darkening of the screen can be also reproduced when a small pressure is applied on the case just above the ethernet port or above the headphones port.
When the screen goes dark, I can see that everything is running normal, if I shine on it with a lamp or strong light. The resulting effect seems to be the same as if I would have lowered the brightness to minimum.
When I don't press the area described above, the screen is just fine. I am sure this problem is not software or OS related. I googled it a lot and my guess is lose connection on the inverter?
One last thing - idk if related - sometimes, when I boot up the laptop, the backlight is turned off and I have to adjust it by pressing F3.
My current problem is that when switching from the mobile power-saving GPU I lose the backlight on my screen when the high performance GPU kicks in. The HDMI output is displaying video when in High Performance, but the screen of the laptop will only show a picture with no backlight, and can only be seen by shining a light on the screen.
Just started happening the last few days, I've tried a system restore (didn't allow it), tried uninstalling all of the AMD drivers and software then reinstalling with their updated drivers, as well as the same process but with the HP drivers that came with the laptop, still the same result.Is it possible for the high performance GPU to be failing some how or is this a software issue?
I keep getting blue screens complaining about igdpmd64.sys x00000050. I noticed on the day that I suddenly started getting blue screens Windows installed a bunch of windows 7 x64 updates. Does the recent windows updates can cause this?
At times I cannot even reboot normally when it occurs. I have had to restore to a previous version.
I am pretty positive that my laptop does have a backlight. However, I didn't need it at the time and I shut it off. But now I can't turn it on. I originally remembered adjusting it through the power options and that there was a little slider to adjust the brightness of either the screen or the keyboard. I could have been wrong though, since I no longer see the second slider for the keyboard brightness. I have tried everything I could find to get the light to turn on. I used the mobility center but there is no keyboard option. I have tried the fn + spaacebar, fn +f5, and my keyboard does not have a specialized key to adjust the keyboard backlight either. How to turn on the backlight?

I use an external display in addition to the built in laptop monitor and the external display is working fine.

i have had a lot of problems with my display since august. although i didn't notice at the time, it happened soon after i installed the Win 7 RC.

i assumed the screen was knackered, but i installed a game a few weeks ago and it brought the display back to life, only for it to look crap again when i restarted. this also happened when i did a clean install of vista, only for the display to go bad when the updates installed.
i have tried many times, but have been unable to replicate this...............

View 3 Replies View RelatedMy laptop shows me a blank screen after the windows bar loading screen. It did an automatic test on my hard drive to fix files, but when I restarted, it still would keep doing this test. I've tried to use a Windows Vista Upgrade/Recovery, but there is no backup and it keeps giving me an error on all types of restoration. I have just tried the Hard Disk Self Test and it says that there is an error #1 - 04 Fail. From what I've read in the forums, I will likely have to replace the hard drive, but how to recover the files from the old drive and what kind of drive I need to replace.

So I noticed having hopped on my FE790 (3-years old) with Hi-Color technology that the contrast is SOOOOOO much better than on my FW465.
The colors on me FE790 look so much more vibrant and it was rather painful to look at the same picture of a multicolored flower on the FW with the FE790 right by its side.
I decided to use the Catalyst Control Ceneter from ATI to try to tweak the settings
I have a new Lenovo Z50-75 with FreeDOS - I made a Windows 8.1 installation, and all went fine.
After installing the around 70 updates - at one point it reboots and I get a black screen, right after shortly seeing the Lenovo Logo ( entering BIOS works ).
It is not booting Windows at all - I can not enter Safe Mode therefore, and I do not get any cursor.
The behaviour is reproduceable, done this 2 times. Also when it hangs in the black screen, the van get reall busy, lound and the notebook gets hot.
At the top of the screen, images look darker and crisper and at the bottom they look more bright and less detail.
Here's an example of an icon that should look the same, but it looks distinctly different (and it's not the camera exposure -- what you see is more or less how it is). Should I return the machine and get another? Do you think Apple will even consider it an issue if I wanted to get it replaced? Do you guys have the same thing? I only noticed when I had a lot of the same icon scattered on my desktop and the same icon looks noticeably different. Of course, I am always the person to notice anything about electronics whereas other people would never have so much as a clue. even though the video files are what got me seeing that things are different, you can kind of see it with the folder icons as well.
for some reason the on screen display meter for my volume when pressing on the keyboard suddenly disappeared, I would like to get this back. I found this thread in the forum URL.... which another was having the same problem I'm having. The only difference is that I'm using HP Pavilion G7 with Windows 7.

I was using my HP Pavilion g7 the other day, while gaming and the screen went black for no appairent reason. i haven't down loaded anything recently and i run virus software.
We went to the HP support web site and went through several diagnotics. When the laptop is rebooted the screen on the laptop will flash images of my desk top but once the machine boots up the screen remains blank. you can see the glow from around the edges but that is it. I have another monitor plugged in currently and the system is functioning propertly except for this. We have also done the following, hard reset,Test for memory modual problems, test the hard drive. I was also trying to update the video drivers but the system tells me the drivers are working properly.
I have an hp pavilion dv6. It was purchased at the end of 2010. My computer teens to get hot a little quicker than normal. It had overheated a couple times, but not recently.I recently went on a road trip and when I got back my computer screen won't turn on. While I was away, I took the bottom plastic screen off and put it back on (one of the sides had come loose and a tab was sticking out). I also tightened all the screws on the main cover on the bottom because some had come loose.When I got home and tried to turn my laptop on, the screen wouldn't turn on. I can hear the fan turn on. The light indicating the wifi was on, but showing that it was off- and it was on when I last used my computer. Also, the capslock light is blinking. I don't hear any sound from the speakers or anything like that. I tried hooking it up to a projector but never got a signal. I tried unplugging it and removing the battery and holding the power button for 30 seconds but nothing changed when I tried turning it back on.

View 1 Replies View Relatedwell i have decided to replace the stock thermal paste on my 5920g, however, i was suprised to see that acer used therma pads intead of thermal paste
im even more suprised to see that there are thermal pads all over my gpu and cpu
heres a rough picture of how it looks like
silver color denotes where thermal pads where installed
the weird thing is that the copper plate of the heat sink only touches the parts of the picture with the orange circle
should i put AC MX-2 on the areas where i found thermal pads or just on the areas where the copper plates of the heat sink touches the core
I've checked my control panel settings and then the advanced settings (for notification icons--which doesn't apply to this problem).
What ever I set, I'm working at my computer and screen always goes to sleep 1 minute after if I don't touch the keyboard.
What am I not getting. I need at least 5 minutes or so before it should go to sleep. My computer at the office only goes to sleep after I make it.
I have had my Hp dv7 notebook for a few months now and have had no problems. But all of a sudden, I turn on the computer and see nothng but a blank, black screen. I do not know if I changed the display settings or what, but I cannot see anything. I know the computer is functioning because the fan turns on and the keyboard lights work. When I connected my laptop to an external monitor, I was able to see that my computer was on and fully functional. In fact, I am using it right now on an external monitor to type this message.

View 1 Replies View RelatedI recently purchased an HP Pavillion X2 2in1 laptop and want to connect it to my TV. The laptop was recentluy upgraded to windows 8.1. When I connect using an HDMI cable, the TV recognises that the HDMI is connected, but the laptop screen will not transmit onto the tv screen. When I hit f4 to toggle the display, it says 'Your PC cannot project to another screen. Try reinstalling the driver or using another video card.'
When I go into control panel as recommended on other queries, the adjust resolution screen does not give me any other options than the Basic PnP display. It's like my laptop cannot detect my tv. It is not in my computer, devices or anything. I didn't attempt connecting it to my tv when it just had windows 8 on it ...
i just replaced the previously matte chi mei display on my hp compaq 8510p gb967ea (WSXGA+), with a brand new lg-philips glossy one (both certified for my notebook, of course) and for the first time ever on that notebook (ie. first time since its acquisition summer 2008) i experience backlight issues now.
just like on my very old nx9030 (which happened twice while under warranty, so its been repaired for free, and then once after the warranty period), the backlight keeps turning off by itself or when touching the lid or typing a bit heavier. so i have to close the lid and open it again to make it turn on again!
i watched out for all the cables within the frame and the one going into the inverter board, so none should be squeezed or so.
shall i open it again and look for a specific cable, jack or something like that, whether something is being squeezed?
