Summary: whilst watching a video commercial on a trusted corporate website, the screen went black (though still backlit). On restarting, screen came up normal (graphics perfect) until the first Windows XP page (with the green loading bar) when there were green and black vertical strips 5mm wide, the green strips made up of four lines, a little reminiscent of that code pattern in movie Matrix. After the Windows page the green lines turned to blue, and then the screen went black (though still backlit), and the usual user login didn`t appear. Leaving the computer to run, the hard disk was active from time to time, then before long the windows logging-in jingle played as if we had logged in, the screen still black. After that, no response at all.

After problem: Laptop can be started in Safe Mode (from where I write this), there are still faint green lines superimposed. I completed a system restore but this has not fixed the problem.

The last few weeks: A number of weekends ago I attempted to open my mouse for the purpose of silencing the clicks, but on opening the mouse half way and looking inside it made itself apparent that it was not meant to be opened (without breaking the plastic case [mouse is GlanzHS by Sanwa]) On closing and restoring the mouse, I found that initially the left button didn`t seem to work, and then it did, problem solved. But then strangeness began: next time on restarting the computer, nothing responeded to the pointer or the left click on the first user login window (not a problem as TAB and Enter worked) then again in my desktop nothing responded to the pointer or left click (right click brought up menus, though left click selected nothing). I found a work around by opening Task Manager, where, after several seconds, buttons responded to the pointer and left click worked, and continued to work for everything else with Task Manager closed. The only exception was Adobe Illustrator, which I used this week for the first time since then, and found again that the pointer/left click were not working as they should.

Would the mouse be connected to the screen problem?

PC: Toshiba Qosmio G30/795LS, Microsoft Windows XP Home Edition Ver.2002 , SP2.


If you could shed any light on this strangeness I`d be most appreciateive.

Is the mouse integrated into the laptop? Did you have to take the laptop case apart to try and work on the mouse? You could have pulled a wire loose for the LCD. If the mouse is external try a different one and see if this solves that problem. You can check your laptops video by connecting an external monitor if the problems persist its the graphics chip in the laptop and its time to ask the boss for a new one or start shopping around. If the external monitor is clear you can be sure its the LCD and they can be replaced although the cost is similar to most low end laptops brand new.
