I have an Inspiron 8200, and have two battery packs for the laptop.  The original obviosuly came with the laptop.  I ordered the 2nd battery over two years ago, and have enjoyed the extra usage on long trips without ac power.

 

At the end of last month I tried to turn my laptop on using AC power with both battery packs in the bays, and the computer wouldn't so much as "flinch".  I noticed the battery cahrge indicator was flashing orange.  I then unplugged the ac power and tried to boot, and had no luck.  I then took turns taking one batter out at a time, and voila when I pulled out one of the batteries, the laptop botted on both ac & dc power.  I then tried to shuffle the bays that each battery was in.  The same end result followed.....whenever I had the "faulty" battery plugged in (regardless of the bay), if the laptop wa soff it wouldn't boot.  If the laptop was on, it would completely freeze.  And in all instances, the orange flashing light came on the battery LED.

 

No modifications have been made to the laptop, it hasn't been dropped, or anything.  So I'm asusming the battery has somehow become defective or just "died".  Has anybody had this experience in the past?  Should I just try to get a replacement battery under warranty, or is there a possible fix?
