    its jus been a year... the battery of my Dv7t is draining very fast...
    first i was on vista, it would shut down directly at abt 30% and the battery would last like jus 45 minutes on full 100% recharge!!
    now i moved to Windows 7 and the battery went from 100% to 6o% in just 20 minutes.. also there is a error showing on the battery bar saying "consider replacing ur battery .. the system might shut down suddenly"...
    what should i do.???
    the problem starting suddenly like 10 days ago before that my laptop was giving like 2 Hrs back up on full recharge!!!!!

    PLZ Help!!!

    Your battery is dieing. I'm finding that HP's batteries are pretty well hit or miss in a lot of ways. My DV5 would last about an hour off of a full charge under "power saving" mode and about 45 minutes on "high performance" mode. When I switched to 7, it wasn't long before it too started saying "consider replacing your battery" you might try to calibrate the battery, but I don't think it's going to save you at this point. Either buy a new battery or use your warranty if you have it to get replaced.

    Calibrate means keep it running until it completely dies.. you will need to turn of Windows automatic hibernate/sleep when battery gets low to do this (or just keep it running in the BIOS until it dies). Are you still covered under warranty? You should be able to get a free replacement if so..
