I have purchased my first laptop recently. But, the problem is many times I forgot to connect it to power supply. Due, to which all of my battery get exhausted and I get warning when it is only 10% left. I have found the option of selecting low battery level. But, I am looking for some notification (can be beep) which should display after every 10% consumption of battery. Is it possible to do so? And how can I do this?
