I bought this notebook two weeks ago, and when the battery is discharged I don't receive any notification. I checked the settings about notifications and they seem good, I have the same setting on another Satellite and I have no problem with it. I set battery critical level at 10% I've checked the battery level on the icon in the taskbar and it was 25%, after a minute the Notebook hibernates because of battery discharged. What's wrong? Maybe the battery is damaged? Or maybe I need a new driver?
