HP LCD Problem

by gsbharaj / September 19, 2008 11:39 PM PDT

hi guys. first of thanks to you all for reading my thread.

well my problem is that i bought a brand new hp 6720s notebook yesterday. it is the best ever notebook i have bought. i love everything about it.
the problem is with the screen. it works fine, but when i try to move it up or down i see a very little brightness fluctuation.but it becomes normal in an instant. mind it is very little noticeable. but it is just when i move. it not always happens but sometimes. now i want to know that is the hinges loose. should i contact the service centre or is it normal?
any kind of suggestions will be highly appreciated.

thanks
cheers....

The screen cover flexing is doing what you see when you press your finger on LCD screens. There is nothing to fix yet given your story so far. Sadly there are very few people that will take the time to explain how things work. Even I won't go too far beyond talking to the pressures on the LCD can cause the effect you wrote about but some become upset when you write about it when they want it not to do that and not the explanation. Go figure.

But you just bought it and if that is a deal breaker, pack it up and insist on another model.

its not the pressure thing. i am quite familiar with that.
it is this that when sometimes i move my lid it seems that there is a brightness level change and then back to normal when the screen stops. it is like some loose connection or something.

They are using the camera to adjust screen brightness.

But as it stands, its new and you are not getting answers from the support line. I can't see it so I can't comment further except that you can call it a deal breaker. Pack and return.

the hp guys says this is normal. but i dont think that this is normal. they say that if we touch the screen from the sides, the brightness will fluctuate. what to do?

Yes the brightness does change with what some may consider very little pressure. Remember that light weight came with a price. Not much structural reinforcement. So try units at the stores of the same model number to see if yours is worse.

My guess is that it's normal

If you've ever seen one of these screens taken apart, you'd know there's a cold fluorescent tube that runs the full width at the base and it's light travels through a plastic panel to disperse it evenly across the entire surface. Any flexing that even slightly alters the orientation of the tube and this panel is going to cause a visible change in reflectivity. This does have anything to do with electrical connections but mechanical ones. I'd not worry.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
