Howdy Ya All,
Kind of a long story but the laptop really belongs to my Daughter. I went to visit my Daughter the other night and she asked me if I could look at her laptop. When she turned it on it took about 6 minutes for the laptop to start up and when it did the screen was so distorted with what appeared to be digital interference or electrical interference or something that caused lines and such on the screen that you could barely see the desktop. She said it had been like that for a couple of weeks and because we could not see the screen clearly the only way to shut it off was by popping out the battery. So I agreed to bring it home to look at it, I figured that I couldn't do any harm to it. (Boy was I wrong.)
The laptop is an HP 2000 2b43dx. She had previously tried to upgrade to Windows 10 through the upgrade process, and I think that was the beginning of her problems. When I brought it home I immediately set about doing some tests so I got into the test menu by hitting F2 upon start up and I ran tests for different performance and hardware issues that it passed. After the 5th test which I believe was for memory, which it passed, I hit EXIT just like I had done for the previous tests, which should have restarted the computer, but when it shut off and fired back up the computer appeared dead. The screen was completely blank. The fan runs and the LED on the power button lights up, but other than that it seems dead.
I tried a couple of things like this, http://h30434.www3.hp.com/t5/Notebook-Hardware/The-EZ-Way-To-Unbrick-After-WinPhlash-Bios-Update-Failure/td-p/548195 but it did not work. I also opened up the computer and popped out the little CMOS battery and put it back in and I sprayed air on the inside when I had it open. The laptop really seems dead and I want to try something else before I just through it away, but I don't know what to do. Help me please to fix this Bleeping Computer.
