EXTREMELY URGENT! HP Laptop Screen Totally Blank
Posted on 2009-02-20
I have a an HP Pavilion dv9207us laptop. My laptop does not show anything on its screen at all, completely blank. I have to hook up an external monitor to use. I tried updating the graphics card drivers that didn't help, then I tried rollbacking to the old driver. I feel that hooking up an external monitor to my laptop somehow messed up the display profiles or something.
In the Display control panel I do see both monitors, but the laptop one is grayed out. I think I had a different profile that came shipped with the laptop but now I can not find that profile. Is there a file folder where it might be?
I have one profile that reads "1. generic pnp monitor on nvidia geforce go 7600" and one that reads "2. default monitor on nvidia geforce go 7600" I thought before this happened I had a different profile name, the one that had the factory settings in it.
Should I try installing a new .icm profile? Where do I find that default one that factory shipped with the laptop? Or am I looking for a display profile, not a color profile?
I need to fix this by tomorrow noon because I have to take the laptop on an important business trip, but right now its totally unusable without an external monitor!
What can I do?
UPDATE: I now got data on my laptop screen by putting the resolution to 1600 x 1200 on the external monitor and then unplugging it. But when I put it to sleep or reboot it is once again blank. I am screwed unless I'm at home with an external monitor.
When I wake it up from sleep mode, if i am lucky enough for it not to be blank, the resolution is all messed up because it is using the generic pnp profile instead of the default profile I think when it wakes up. It only lets me put the resolution to 1440 x 900 on the laptop, when it factory shipped it let me use 1600 x 1200. It is unreadable it if is above 1024 x 768, a lot of static/flicker. How do I change the order of the profiles so that the default profile is tried first after waking from sleep mode or rebooting?
