I recently brought an E5510 core i7 laptop and wanted to fit a backlit keyboard to it. I brought a Dell retail keyboard which has the backlit option which I have installed with no problems. All they keys and mouse cursors are working.

In my Dell 5521 15r I have activated the following 2 utilities simultaneously. Hence need a wise decision whether to inactive one of these or to keep both active ? A) "DESKTOP MODE BATTERY CHARGE" B) "LONGEVITY MODE BATTERY CHARGE " Please advise. K.Rgds/Judebd
