    Hello!

    For the last week and a half the built in display on the Windows 7 HP Pavilion dv4i laptop which I purchased a few months ago will not display anything but a black screen. There is power to the screen, which stays illuminated and flashes during the correct transition times between the hp screen, the bios wait, and the windows start screen, but there is no interface or video whatsoever. I can get the video to display on an external monitor using VGA once the Windows login screen pops up, but that means I can't use my laptop as a laptop or see to access the BIOS. It is possible this is a problem with the CMOS preventing the laptop from recognizing the screen (also on one boot the date was defaulted back into January of 2009), and I have ordered a new CMOS battery to see if that is the issue.

    However, there is enough going on to convince me that might not fix the problem due to a software issue. There was one prior reboot since the problem started where the screen worked, but on the next boot it was broken again. In the device manager the computer only sees two Generic PNP monitors (one of which is the display that does not respond) instead of their proper handles. In the display options I get the external monitor (a HANNS-G labled properly) and then the option for a VGA output monitor, which I can turn on but it does not change the laptop's display. The other issue is that I have the HANNS-G monitor plugged in via VGA, so it makes no sense that the computer would see another VGA output when that output is already being used for the only monitor it has recognized.

    I have tried system restore to before the issue occurred, defaulting to the last windows update a few days before the problem occurred. That changed nothing. I tried startup repair, which tried to do a system restore and then crashed. I reinstalled the display drivers and BIOS flash with new versions more than once. That did nothing. I reinstalled the drivers again, and this time the ATI driver crashed and burned when it tried to install and I had to turn off the computer after it froze. It says the driver is installed correctly when I go to reinstall, but now in the computer properties it does not list my video card and I cannot activate the Catalyst Control Center which allows the driver to use the card.

    This computer has a quirky switchable graphics setup where I can save power by switching between the Radeon and an Intel Graphics Media Accelerator that runs off the processor. Usually you can just click into the menu to switch the graphics, the screen will flash off (this crashes any playing video and makes your desktop background disappear indefinitely) and the other graphics setup will run. Right now it is stuck on intel. For some reason I suspect that this wonky setup is somehow responsible for my screen issue, but right now I am pretty lost.

    Also, just to clarify, when I got the computer I reinstalled windows 7 with a clean copy to get rid of the bloatware. The reinstall went fine and it has worked well until now. I activated the Administrator account and changed that to my name. I've been using that account since then even though it was not the original account (my name) I installed Windows with. I have had two Trojans which were blocked by my antivirus programs. I have kept up to date with drivers, windows updates, anti virus updates, and other maintenance like defragmenting the drive. I am a pretty heavy computer user and regularly use many different programs at the same time, but I know how to use my computer carefully.

    Thanks in advance to anyone who can help with my problem!!!

    I also did a HijackThis log if that is helpful:

    Hi at 4months in this should not be happening and you have done a lot of troubleshooting already,If it where me (and it is not) I would be on to hp or the retailer and have them sort it

    How much time elapsed between the new install of W7, and problem onset?

    What changed?

    What's the temporal relationship between problem onset &
    ?

    HOW, exactly did you wipe out the bloatware? Which DVD did you use; from HP; 1 you created? Did you re-format the HDD?

    Does that mean the display works part of the time?

    If so, boot to safe mode.
    edit: What happens if you boot to the W7 DVD?

    If that fails, I'd follow joeten's suggestion. :)

    joeten,
    I spoke to HP and they are the ones sending me the CMOS battery. If that doesn't work I am sending the computer into them. However, I am trying to avoid backing up everything and spending two weeks without a computer which would be pretty devastating, so I would like to avoid that if possible.

    rainforest123,
    I reinstalled W7 as soon as I got the computer. I got it in March, and this problem started about a week and a half ago. The trojans were a couple months and then a couple weeks ago but they were blocked before they did any damage.

    I wiped out the bloatware in the install of windows since I did a clean install, nothing from before I bought it (like the hp bloatware) was on there. I used a ISO utility to burn windows to a disk (http://store.microsoft.com/Help/ISO-Tool) and then I activated the new install using the key on my laptop.

    I have booted to safe mode multiple times to no avail. When the screen flashes, it just goes between a lit black screen and a non lit screen. What I meant is that in the same places where the video signal would go in and out (between the hp logo screen, and the windows loading screen) it still flashes. That indicates that the screen has power and the computer is trying to use the display.

    I have not tried booting to the Windows 7 DVD, but my expectation is that I won't have video for that interface since I don't get any video until the VGA connection activates and displays the Windows login screen on my external monitor, no exceptions. I will give it a try though. I'd do almost anything to not have to clear space on an external to backup everything and reinstall Windows though.

    Thank you both for your replies!

    Also, new symptom:

    My webcam and microphone, mounted to the display, both stopped working today. They had been working fine during multiple previous uses but today I was using them and they suddenly stopped responding.

    This is starting to look like a connection issue somewhere in the hinges or by the LCD. The connection near the motherboard to the display looks fine, but I haven't taken apart the LCD. I am concerned about damaging the screen or voiding my warranty though so I don't know if it's worth it.

    Or it could still be the CMOS, drivers, unrelated issues, or even the OS... Bleh...

    g :
    After turning on the PC, does the HP splash screen appear? Does the POST screen appear?

    I understand your trepidation, but if you have an aux monitor connected, I would [ & this is a guess ] suspect that you will be able to see something on the auxillary monitor.

    Not even the HP splash screen?
    WOW!

    You can't even enter the BIOS?

    bummer that you have to send your HP away.
