Dell Latitude E7440: Sleep issues


Recommended Posts

Everything is working fine on my dell e7440 except sleep and battery %. 

The computer sleeps alright but mostly wakes up to a dark screen. I have tried darkwake=0,1 and no bootflag, nothing worked. 

The other thing is that the battery % doesnt update automatically. I have to manually refresh it. 

Can anyone please have a look at my efi and suggest any changes. 

Thanks a lot. pls hellp.

what exactly is a dark screen mean? like nothing or there is something displaying but the back light is not on or its very dim? if that is the case of it being back light then you probably need to get your nvram working properly.
