[SOLVED] laptop display goes blank and does not even show the bios - Page 2

dai · 01-16-2008, 10:57 AM

not being aquainted much with l/tops,so my opinion does not count for much on them
i would think it was the video chip which would mean a m/b replacement which is only viable under warranty because of the costs involved

gbhavik · 01-17-2008, 06:47 AM

what if i restore the laptop to factory setting... will there be any chance then?

Hi,
Let see if we can diagnois this a little further. We might have missed something.
The Ram could play a part in this if it has or is failing.
Try to see if you could go through this diagnostic sheet and see what happens.

hey man still no luck... but thanks for the effort .....

**BCCOMP** · 01-18-2008, 08:30 PM

Hi gbhavik,
No luck with the external monitor and the diagnostics (Posted above) leads me to believe that it points to a bad MoBo. Contact HP to see what they can do, unless you have the skills to replace the MoBo(Maybe exspensive).
Sorry,
Bikll

the external monitor stuff you told me to do was something as follows right.....
what i did was...

i connected my lapy with my PC monitor. and it showed the display of the windows when in safe mode or there is no drivers installed for the G card. i pressed.. fn+F4.. and is showed a small box at left bottom side of the screen and was an arrow showing External monitor to Laptop.. it stayed there for a moment but nothing happened to the laptop. i installed the G card drivers and the laptop never showed the desktop... in both situations whether external or not there is no display of boot up screen.....

so what i did was correct for diagnostics or had to be done in a different way...

and for the RAM stuff there is two 512MB ram so i removed the batteries and then both RAMs and then started the laptop.. of course there was the beeping sound cause of no RAM.. then i again inserted the RAMs and started.. still no sign of lady luck.

so thats what i did.. anything else if had to be done.. plz tell me.. i m not too good wid laptop problems lol.

Lets see if we can simplify this.
When you hookup the external monitor, are you able to see anything on the external monitor, BIOS or Windows?
Thanks,
Bill

gbhavik · 01-19-2008, 10:10 PM

Only Windows i.e. from the moment when windows is loading.. can be seen on the external monitor.... during booting the screens remains blank....

So, now you are saying you see the Windows Logo on the external monitor but after that the screen goes blank on the external monitor? I want to just keep this to the external monitor for now not the laptop screen OK.
Thanks,
Bill

gbhavik · 01-20-2008, 05:56 PM

No no... i cant see the boot up screen on the external monitor, but i can see everything else happening after the windows loading screen...i.e. i can see the desktop and all the stuff...

**bhahar84** · 01-20-2008, 10:21 PM

Hi gbhavik!!

I'm bhahar. BCCOMP is my mentor, let me try help you here

Ok, let me verify the issue further with you

So you're now connected the external monitor to the laptop? And you cannot see anything on the laptop screen and external monitor, until the windows load up, which is after the "welcome" screen come up, right?

gbhavik · 01-21-2008, 02:37 AM

exactly !!!!

**bhahar84** · 01-21-2008, 04:12 AM

And again gbhavik, after the system fully boot up, you can ONLY see the windows on your external monitor, while the laptop screen remain blank, am I right? if I wrong, correct me, ok

gbhavik · 01-22-2008, 01:09 AM

yes the laptop screen always remains blank with the back light on... and on the external monitor i can see stuff only after the windows loading screen.. nothing before that.(i can see the windows loading screen)

**bhahar84** · 01-22-2008, 01:26 AM

Ok gbhavik. Can you try to go to the Device Manager, see if there is any yellow exclamation mark or yellow question mark on any devices inside there?

p/s:
You can go to Device Manager by following this steps:
1. Right click My Computer
2. Choose Properties
3. Click on Hardware
4. Click Device Manager
5. Try to locate any yellow ! or ? here

gbhavik · 01-22-2008, 02:22 AM

ok.. so the only ?! i saw was for Ethernet controller but it has been there like for ever.. nothing else... and i hope you know that whenever i install graphic card drivers the lapy wont work.. it restarts...it works only when its in safe mode or no graphic driver installed... (the screen always is blank for lapy...)

**bhahar84** · 01-22-2008, 04:15 PM

Is the GeForce 7600 Go listed under Device Manager? Is it detected? Can you check the warranty status of the lapy for me?

gbhavik · 01-22-2008, 10:39 PM

yeah it is listed and the lapy is in warrenty

**bhahar84** · 01-22-2008, 11:27 PM

Ok gbhavik, can you try to go to the Device Manager again, click the plus sign beside the Display Adapter, and now try right click on the Geforce 7600 Go, then choose Uninstall. Try to restart your computer then, and see whether it detected. See whether you can see anything on the laptop screen as well.

If its not, it might be the LCD converter is having a problem. You might want to send the laptop to the manufacturer again, and they will repair it for you

gbhavik · 01-23-2008, 01:02 AM

no luck though... the problem still persists... i think i have to go to the HP service center... anyways thanks for the help bhahar.. thanks for helping in any way possible... by the way any idea how much time do they take to repair? well have to deal wid the broken left hinge too...
