I've recently came across a problem with my laptop Acer Aspire 8530G. I get this annoying thing when every time I move just a little my screen (for example I want to adjust it cause I'm sitting lower or higher) it goes black. I then have to press Fn+F6 to return to normal but in a couple seconds screen goes black again. Sometimes this keeps up non-stop... Then I just close the lid and open it - sometimes it goes black again and I repeat the step or it goes normal again till the screens gets moved just a little and does the same thing. Also, I've noticed that sometimes the screen goes not to completely black but I can see the desktop if I look close (the screen is just very dim). I've also had some problems before with sleep mode when I would let my laptop go to sleep mode and after resuming it the screen would be just all white and I would need to reboot my laptop. Also, not sure if this is relevant, but once I tried to adjust screen brightness and it would not change until I closed and opened my lid.
My laptop specs are:
AMD Turion X2 dual core mobile technology RM-22 (2,1 GHz, 1 MB L2 cache)
18,4 inch HD+ Acer CineCrystal LCD
Up to 2304 MB ATI Mobility Radeon HD 3650 HyperMemory
4 GB DDR2
OS Windows 7 64bit (reinstalled it a couple months ago)
Please help me with some advices or possible problem solutions.
