i bought a compaq presario cq56 from a vendor who came to the country from America. less than one month after, if I charge the battery to 100%, on removing the power plug, the battery falls dead within 15-20 mins and my linuxmachine just dies instantly without even hibernating. Sometimes, the system complains on boot up that battery is faulty, sometimes it does not. sometimes, the linux machines complains of a tcs?? failure, sometimes it doesn't.. I wonder if there is any issue yet with that system as to power, or the vendor hoodwinked me?
