U510 Keyboard backlight stopped working

2014-11-04, 19:58 PM

A few days ago, my Ideapad U510 keyboard backlight stopped working. Formerly, pressing Fn-Space switched the keyboard light on and off. Now the computer does not respond to Fn-Space. I am running Windows 8.1 .   Any similar experiences / any Lenovo staff or others with a solution?


Thanks, Ben

Hi Bebbed,                           


Welcome to Lenovo Community!        


As per the query we understood that you are facing issue with the keyboard backlight not working in your Lenovo U510 laptop.


As you have mentioned that the keyboard backlight was when function key and spacebar key is pressed, as there might be issue with the power management, please reinstall the chipset driver and power management software.


Click here for the power management software.


Upgrade the chipset driver as this model has the inbox driver for windows 8.1.


If still the issue persist then there is a issue with the keypad which needs to be replaced, please visit the nearest service centre for further details.


Click here to open a link where you can select the country and get the exact contact support number. I’m sure they will be a great help.


Hope this helps! Do post us back for further queries.                 


Best regards,
