|If you hover the mouse over the battery icon in the system tray it |
should tell you how charged the battery is. If the icon isn't there
go into Control Panel/Power options and check there. Generally
speaking circuitry within the laptop should prevent the battery
from being overcharged. Batteries don't last forever and if it's not
keeping the laptop going for more than an hour then chances are
it needs replacing.
