I have a keyboard that should be back lit but is not; I removed the battery and drained the computer of power and when I replaced the battery, the keyboard was back lit. After putting the comp. into sleep mode the keyboard was no longer back lit. Restarting the comp did not solve the problem.
The comp is a Dell Inspiron 15-5555 running windows 10. Do not have the ability to change brightness with function keys. The comp was connected to power source when this happened. Dell suggested the steps I have described and say they will get back to me.
Thanks to all who have responded. I am replying this way because I could not figure out house to use "MultiQuote".
