I tried turning on my Joybook r45 but there is no display at all, just a screen that lights up but nothing..

Im not sure but for in some rare circumstances,especially perhaps Benq(they produce niche items as well ) there might be a load up procedure for the operating system--Consult or download theoperators manual for your model--with this manufacturer its too early to say you have no operating system but it also might be the case.

Generally ,a screen that doesn't turn on may be a sign of a malfunctioning screen or a bad connection between the computer and the monitor. If the problem keeps occurring, try to keep track of what's happening when the error takes place. Pls visit : learn ruby on rails
