I acquired a computer from my work that they said doesn't work, it is a hp pavilion G7 1158 running windows 7 with 2gb of ram. The issue I am having is that the computer turns on but the screen stays black, I have tried ram from a different computer, a good hard drive , hard reset, checking the screen with a flashlight (no dull picture or anything) and also connecting it to my tv with the hdmi out and rgb line. I am completely confused to what it could be. Also the fan does come on when turning on but then shuts it's self off due to not being on for a few days, any help will be greatly appreciated!!

Are you sure the RAM you tried is compatible to the laptop? When you power up, do any lights come on? If so are the flashing, solid, and what color are they? If I understand correctly, it appears the computer does boot up but just no display?

Please try this. Hook it back up to you TV then hit Fn button and F4. If this doesn't work try Fn and F5. This should switch the laptop to external monitor mode. If neither work, I'd say you have a bad graphic card.

Most likely then you need a new screen.

Please try this. Turn computer off, unplug and remove the battery, hold the power button for 30 to 60 seconds, plug in and try to power on. If it powers up without the battery it could be a dead battery.

If that didn't work I am sure you need a new screen. I'm pretty sure the graphic card is ok. I'm also sure the motherboard is ok. Screens for your model start at around $70 on Amazon.

Other than hooking it up to an external monitor and making sure the button by the hinges isn't stuck down,(the button that turns it off when you close the lid) you can take it to a repair shop that has a tester.
