Was having warning replace battery for a couple of months. Used power adaptor as battery would only last a few minutes. Was typing document then laptop went into hibernation and will now not power on. Is this due to the battery being dead or is it something more serious?
Yes, a dead battery can cause power issues even if you are using a charger as power. I would open the unit and unplug the affected battery. You should be able to use the laptop with the internal battery unplugged and the ac adapter/charger to power it, but as with a desktop when you unplug the ac adapter/charger from the unit you will lose power. However, look into getting a battery replacement.
