I have an HP Pavilion dv4-1428dx that I am getting an overhearing error message on start up. I just recently did a system restore via f11 at start up. Since than they restore I know have this message: The System BIOS has detected your notebook PC was placed in hibernation to avoid overheating. The system is now operating normally and your data should remain intact. Overheating may occur if the cooling vents are blocked or the operating temperature exceeds the specification. The notebook PC should return to normal operation once the situation is resolved. System Temperature (90D) ENTER - Continue Startup Not sure what all this means, but I never had this issue until I did the restore. Now I get this message every time I start it up. Any ideas on how to fix this would be greatly appreciated.
