I was wondering if anyone could help me out with this problem. I use an hp ProBook 4540s and I'm not quite sure why but whenever I restart the PC ( whether after a Windows update or perhaps after a hard reset) the display doesn't work. The backlight turns on but doesn't the screen doesn't show anything. I've tried a lot of things, taking out the battery (both the main and cmos batteries), reseating the memory module, connecting to an external display, reinstalling graphics drivers, reassembling the pc, and sending it to be repaired. Each of these has solutions has only been temporary. I was wondering if anyone had experienced this same problem, or at least knew exactly what was going on and if there was one straight way to fix it? I can't afford another PC right now
Thanks in advance
PS. The whole warranty thing doesn't work in my part of the world so it's out of the options
