Hewlett Packard, model structure dv4-2160us Laptop. I bought it brand brand-new about 4 years ago. It is in fantastic condition aside from the fact that it just recently started flashing a mistake code (3 flashes on the LEDs) after about a minute of trying to boot up. Boot up does not succeed, the fans run and you can hear the processor running, but the screen continues to be black. I'm unsure exactly what is wrong with it, and I'm just going to get a new computer system. You could be able to fix it inexpensively, I have no idea. The stickers can easily be removed. Call or text!
