I have an HP Pavillion dv4-2040us with Windows 7 Home Premium x64bit. After 10-20 mins. the display would power off and the power lights, HDD lights, wifi lights are still lit on the console. Check the event log and found a "kernel power error" causing shutdown. Performed a force shutdown and sometimes I would receive a "BSOD" [stop: 0x000000ed]. After researching the kernel power issue I found that after disabling the HD video driver the unit would work fine. This is only a temp. fix. Need help?
