Latitude E 6230

​ I have Latitude E 6230 Recently it has developed a fault ​

​When i awake if from hibernation mode it wont automatically go to the wifi network I have to connect it manually and it takes a while to connect​

​This problem does not arise if i have turned the laptop off when it is switched on it goes straight to nearest wi fi network​

​Dell have suggested changing the hard disc but i have so much on it I would be loath to attempt to save it all, also on my last laptop once dell started messing with innards i had to get a new one with in 6 months​

​Any suggestions would be very welcome​
