[SOLVED] laptop display goes blank and does not even show the bios

gbhavik · 01-14-2008, 08:33 AM

There was this problem i encountered yesterday. While playing FIFA 08 there was some graphical glitches and the screen started flickering. i managed to see what the error was. it read like.. Nvidia graphics driver has encountered some problem please save you work. i managed to shutdown the lapy, properly. but now the thing is that my laptop will start but wont even show the bios. the screen is blank but there is power running through the screen. and once i even herd the windows log on sound. what could be the problem and what will be the remedies?

specs..

HP pavillion dv 9000

intel centrino duo 1.8GHz
1gb ram
160 gb hard disc.
nvidia 7600 256mb graphics card.

when you list parts list the full discription you listed
nvidia 7600 256mb graphics card
this is not what you appear to have
this is
nvidia 7600 go 256mb graphics chip
do you see a screen in safe mode if not shine a torch on the screen and see if you see anything

gbhavik · 01-14-2008, 08:37 PM

Oh yeah, sorry missed out the GO part in desperation...

ok, the thing is that even if i dont get any display the back light is always on. so shining the torch made no difference.. another thing i did was that i inserted my HP laptop's hard disc in some other laptop, started it in safe mode and uninstalled all the nvidia drivers. then i again put the Hard disc back to HP lapy and started the lapy. now what happens is, the screen still remains blank from the start without showing even the bios, but it starts up as a normal laptop, you can hear the windows logon screen, you can restart the lapy again judging the appropriate keys.

is the laptop under warranty

gbhavik · 01-14-2008, 11:32 PM

i think so may be... why any serious problem?

dai · 01-14-2008, 11:57 PM

can you connect a monitor to it to see if you get a screen
if not
did you install the correct nvidia go drivers

gbhavik · 01-15-2008, 12:12 AM

well i will try connecting it to the external monitor and tell you... and the nvidia drivers were the latest one and was using for almost two months and no probs what so ever....

dai · 01-15-2008, 12:32 AM

if you are sure they are the correct drivers,you did reinstall after you removed them? on the other laptop and the external monitor gets nothing
i would suspect the video chip

gbhavik · 01-15-2008, 12:47 AM

i tried to find some go drivers for go 7600 but none is available.... so i tried from laptopvideo2go.com and things went fine no probs...

and yes the external monitor shows the stuff from the laptop and when i reinstall the drivers for the graphics card the display goes away, even the back light of the laptop goes away and restarts after some 5 secs....

Hi,
I agree with dai, See if you can hook it up to an external monitor and get a sceen. See this link:
http://h10025.www1.hp.com/ewfrf/wc/d...dlc=en&lang=en
Try hitting fn F4 you may have inadvertly set it to external monitor.
If not you may have taken out the graphics card. What is the exact model Pavilion dv9000 what? Also, what version of the nvidia driver did you use? There is a possibility you may have a faulty LCD inverter.
Let us know how you make out with the external monitor.
Thanks,
Bill

gbhavik · 01-15-2008, 01:16 AM

i was using nvidia drivers version 169.28....

so what you are saying is that when i connect to the external monitor i should press fn+F4.. right? but you know i did it but no change though. so is it possible that something is wrong wid my laptop graphics card? cause according to what you said, i understood is that when the graphic drivers are not installed its using the default drivers.. but the thing is even if its using the default drivers it should atleast show the bios... its not even showing up the bios.....

**BCCOMP** · 01-15-2008, 01:26 AM

Yes, when the graphic driver is not installed windows will load a generic driver. You should still get a screen. Seeing you did not and you are sure the external monitor is connected correctly I would suspect the graphic card (Chip). I am unsure if this is actually part of the motherboard or if it can be replaced separately. Most laptops they cannot be replaced as they are part of the MoBo. If this is under warranty I would call HP.
Thanks,
Bill

gbhavik · 01-15-2008, 04:39 AM

ok.. but i had a doubt that if this graphic card of mine i.e. Geforce Go 7600 has a dedicated 256 mb ram, then still it is possible that the card is integrated.?

**BCCOMP** · 01-15-2008, 06:20 AM

I believe it is intergated via a chip design. Can you do me a favor? Disconnect both the AC adapter and battery. Press and hold the power button key for a few minutes to disharge any remaining electricity .Then remove the Ram and reset it. Reinstall the battery and AC adapter and see if it boots up.
Thanks,
Bill

gbhavik · 01-15-2008, 07:07 AM

no... nothing happened.. the thing is that it does boots up but does not display anything on the screen except the back light...
thanks..

**BCCOMP** · 01-15-2008, 07:13 AM

Sorry,
It sounds like a Motherboard issue. If it is under warranty HP should beable to help you.
Thanks,
Bill

dai · 01-15-2008, 08:56 AM

try these drivers
http://www.laptopvideo2go.com/nvidia...ries/16758.exe

gbhavik · 01-15-2008, 09:39 AM

dai · 01-15-2008, 10:20 AM

they won't let you link to the driver there so use hp's
http://h10025.www1.hp.com/ewfrf/wc/s...os=228&lang=en

gbhavik · 01-16-2008, 08:18 AM

hey dai, i had that driver you directed me for, so i installed it, but still no luck. i pressed fn+F4 again. nothing happened. what do you think what could be the problem be. because i am somewhat not yet convinced that its motherboard chip problem......
