So i got this computer the day i graduated highschool so sometime in june 2008 . I have used it everyday since. It went through 4 terms of college allready and has been real reliable and allowed for numerous hours on Tb

.
BUT
Lately the battery dies super quick, right now its plugged in as i type. When i remove the charger it goes form 100% to 93% in less then a minute. Basically this is not normal for it , it could hold a charge for hours.
Any computer savy people out there? i just need this sucker to make it through college .
