This post is regarding my Dell Inspiron 1525 laptop, vista home premium, 32bit. Computer was running fine then the screen suddenly went black. I read in a couple forums that the computer may have been hot, and to turn it off for a while. Since I Couldn't shut it down properly, and control, alt, delete didn't work, I had to just press the power button until computer turned off. When I restarted, everything was fine for a few weeks. This morning, the screen went black again, I restarted the computer, saw the DELL logo for a split second, then screen went black. Every restart the same thing happens. I have read about checking for a display using an external monitor, and sorry to be so clueless, but would that be using an HDMI cable from my laptop to my HDTV? If I do this, will the connection to the tv ask me to do anything with my laptop, which I can't do, since the screen is black.
The laptop is 5 years old, I've been reading about this subject in other forums, about inverters or getting a new screen, would that even make sense?
