I am selling a A135 model 15.4" Toshiba Satellite Laptop. I've really taken care of this laptop, hardware and software. I'll begin to point out that everything works great but the lcd screen. I had it checked out and apparently after a certain period of time on laptops the graphics card goes out. I ve been using it with an external monitor. It works great with big led lcd or plasma tvs, via the VGA cord. It has the dual core processor, 32 bit windows vista operating system 2GB of ram, 320GB of harddrive. 4- usb ports, 1 Vga port, 1 Ethernet jack.
