On a Dell Vostro 1510 laptop (service tag: 9gypwf1) with Windows 7 Pro, I turned the wireless switch back to "on". Then I uninstalled some stuff and installed norton. I noticed that 3 of the 4 usb ports didn't work. Dev Mgr had a USB controller with code 34 (shut off due to a problem). I uninstalled the controller and rebooted.
Now there is no image on the screen at all when I turn the computer on and off I never see any kind of bios message or splash screen or boot options menu. There is no text at all. I don't see any kind of light on the screen at all.
I tried removing the battery and power, and also holding the power button down for 30 secs to dispell static. But there's nothing on the screen when I turn it on.
What I do see when I turn on the laptop: The power light and the bluetooth light come on immediately and stay on. The hard drive light comes on briefly then goes off. After a few secs he capslock & scroll lock come on solid and stay on. The numlock key is blinking.
I hooked the laptop's external display port into an external monitor and pressed the lcd/crt key combo, but there's no image.
On google I see everyone's complaining about dying dell vostros:
and there was some kind of settlement regarding the GPU of this model:
Before I give up, anything else to try?
