I've been using this laptop for about 2 years now and I've had this problem ever since I bought it. My laptop would randomly display a "battery low" notification(taskbar shows that battery is empty) although it is no where near 0%, then the notification will disappear after a second. I asked the guy from the shop and he said it was a software bug which would go away after a few windows updates. Nothing has changed at all after these 2 years and the problem has gotten worse. Now my laptop shuts down after the notification. It even shuts down when I have it plugged in. These "battery low" scenarios don't seem to have any relation with temperature or disk usage. Is this really a software error or is there something wrong with the battery?
