Hi there. I am dealing with an Acer Aspire 5735 laptop. When powering on, I can see everything working on the laptop, but it is VERY, VERY dim. Pressing the fn + f6 buttons causes the screen to come to life, but only for a split second - it just flickers brighter then returns right back to the very dim screen. Could anyone give me some ideas on what could be causing this, and what I need to do to fix it? Many thanks!!
