I just got a new battery to replace my old battery which was dead. When the new battery came to me, it had a charge, I could tell by pushing in the button on the side and 4 of the 5 lights came on green. I put the battery in my computer and it said it was charging it. Then, it went to zero percent charged. I took the battery out and pushed the button and now only the first light comes on and blinks green. How can the battery go from being almost completly charged to not at all? The third party I bought the battery from said to upgrade my BIOS, but I tried that, and it said my BIOS were already up-to-date. Any ideas?

Lithium/Ion batteries need at least 12 hours of charge time before they are actually charged. Before going further I would suggest letting the battery charge overnight. Incidentally, the BIOS version has nothing to do with the battery charging. The BIOS reads the terminal voltage of the battery and reports the reading to the OS. The OS then makes the decision to shut down based on the charge level of the battery and whether or not the unit is connected to the wall adapter. Caveat: never run your laptop on the adapter without the battery installed. The charging circuit will think it's looking into a deeply discharged battery and it's voltage will rise to it's maximum open circuit level. This has the potential for damaging the charging circuit as well as the laptop. If you know how to use a multimeter or know someone who does, read the terminal voltage of the battery after an overnight charge. It should be within 5% of the batteries rated voltage. Be careful not to short the terminals while doing so.
Also, it may be too late for this, but you should never substitute a 'third party' battery for an OEM one without the approval of the manufacturer. You risk damaging your laptop and/ or voiding the manufacturers warranty.

There are a million korean and chinese websites selling batteries that you should NEVER put in your computer. Chances are, it's garbage and you've been had.
DO you have a multimeter? If so, google multimeter + checking battery levels. After a few hours you will realize what I said above is correct but if you are the kind that needs more proof then by all means spend the time doing so and most of all, good luck.

The laptop manufacturer may have a "battery recalibration" program which might help (I've run Dell's one in the past).

you could recharge your battery by plug it in outlet.
