Hp pavillion dv4040 us problem with monitor ''button''
Hello all. I have a hp pavillion dv4040us laptop. I believe the problem is with the little rubber button that the top of the laptop hits when you close the laptop. When you reopen, the monitor will go on for a few seconds then go off. However when you push that button in and out (ive set it not to goto sleep) the monitor will go on. I currently rebooted the pc back to its original form, but that didnt solve the problem. It sometimes will stay on for a few seconds then all of a sudden turn off. When the screen is on, it looks like the pic is okay. At the moment i also have an external monitor hooked up to it. Can anyone tell me how to repair that little rubber button, if that is the problem? Thanks

You will not find contrast controls for most laptops. This is a funtion that you found on most desktop CRT monitors. However, xp and vista has some features on smoothing and such of your viewing icons in the basic right click on desktop/select properties
This question requires a techincal person to first, attach an external monitor to the laptop to see if there is video going to the external monitor? Then while the external monitor is hooked up he should run full diagnostics to see if the motherboard video adapter is fully functional? If it is? He has to open the laptop and trace to see if the plug from the motherboard to the monitor needs to be reseated. The worst case scenario is you will have to replace the motherboard.
If the notebook's video card (which may be on the motherboard) is successfully displaying images on an external monitor it sounds more like a problem with the notebook display or its connections. Probably the motherboard is OK.
You could be expierencing a problem with your monitor screen. try this.... connect another monitor screen to the VGA port of your laptop. Now try booting up. Look for and push Fn + the key that turns on a secondary display. if the monitor screen comes on. you need
another laptop monitor. At least you can use your laptop with the second monitor for now.
I believe that's the hinge screws on the computer that's too tight. If you have screwdrivers that can fit into the hole of the left hinge, you can just loosen them up & that should fix it. If you're not sure what to do, just take it to a local store and have them loosen them up.
