Hey guys! So i my problem compels me to post my first ever thread here, I have been reading and benefitting from this forum a long time now.. I own a Mac Book Pro Mac OS X Version 10.4.11 Now.. I lost my charger that came with this notebook once, and i started using my brother's Mac Book charger for a while. After a couple of months i bought a new one prescribed for the Mac Book PRO... Only to realize that the battery had failed me by then, my laptop was no more a 'mobile' device, it would only work when plugged in to a charger! After this i went through two 'more' new chargers as each failed me for some reason :-? ... Now i have a mac book pro, which doesn't work without a charger ( the battery icon shows a battery thats runs out 20 times more quickly than normal and the laptop shuts down when it comes down to something like 87%), Also no matter what charger i use now, it flashes constantly going back and forth from red to green. Please help me with a solution and unravel this mystery for a technically handicapped person Is buying a new battery and a new charger the 'IT' solution? Thanks in advance !!
