My laptop goes into hybernation automatically all of a sudden. Please suggest where the problem lies.

Try to disable hibernate. Remove the temporary files which includes the hibernate file

Go to Control Panel->Power Settings and there's a box which says "System Hibernates" with a time interval. Increase it to your likes or choose "Never" to stop hibernating automatically.
