Hi,
I'm not sure if this is normal or not, but I couldn't get to my charger in time to charge my laptop up before shutting down. When the battery died, I had to turn it on again. For some reason I went through the Dell logo then entering my password for my hard drive, which isn't suppose to happen. You would normally end up on login screen, as you would when you come out of sleep mode.
On my old Dell laptop inspiron n7110 when the battery died, I could resume when plugged in. I hope this isn't a issue with the motherboard or anything internal.
Dell Inspiron 15 7000 series
Windows 10
i5-4210U
64-bit
6GB RAM
SSD
Thanks
Danny
