I have my laptop plugged into the mains for over an hour now, When I check the battery it says plugged in charging, 1% It has not moved from 1%
Does this mean that the battery is dead?
If your battery has definitely died you may want to google if yours is able to be 'cracked' - opened up. You can buy some good quality cells and renew the battery to as good as new (or better) for 1/3rd of the price of a new one. Some soldering and common sense required.
