Re: Battery not charging. Power Adapter ok
DC jack issue usually.
Or a bad repair- many techs not skilled enough will wind up losing RV1,RV2 or RV3 MOV. this is so small that I had documented it on my site. The chip has no values printed on them, and are hard to find "Close-Up"
But fear not, most of the times it is simply a DC jack replacement. They are about $8 on ebay. And only a skilled tech should replace it.
How they fail?
It is a circular tri-axial ring inside, the leaf type contacts become fatigued and no longer pick up power. Or the center contacts become fatigued.
OR the jack left the factory with insufficient solder and repeated use caused it to crack.

Maybe the AC Adapter Power Cord is not working. If you can't get on the laptop with the power cord then it is bad and the battery might be drained so you have no power source to power up the laptop. If the laptop works only off the Power Cord and the batteryis not charging, then the battery is dead.
To check to make sure the Power Cord is working remove the battery and let thelatop run for 10 minutes or so.
To check to see if the battery has any charge left in it put the battery in andremove the power cord. If it won't boot or shuts down then the battery is deadand needs to be replaced if the power cord is ok.
you need to make sure your power adapter is providing enough power to both run the laptop & charge the battery. A very good way to do this is to compare your laptop voltage & ampere requirements (written on a sticker on the bottom of the laptop) with the voltage & ampere ratings of the power adapter. Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amperage of the power adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating, or else the power adapter will be providing insufficient amperes to charge the battery. Of course, the power adapter's nominal amperage might be ok, but it degraded on usage. You can verify this by testing using a good or new power adapter. If the battery did not charge using the new power adapter, take the battery off the laptop, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the laptop & try again. If this still did not resolve the problem, then the battery itself could be bad. Try it on another laptop, or try a good or new battery in your laptop. If this did not work, there might be a possibility that the charging circuitry on the laptop's motherboard is defective & needs servicing. In order to do this, the laptop needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether
Yes, most likely you may need to replace the battery. Try to get a different cell capacity this time (I do not know if you currently have a 6 cell or 9 cell battery). Once it's not keeping a charge it most likely has a problem.
Hope this helps...
try to darin the batter first. heres the procedure. take out the battery and unplugged the power adapter. press and hold the power button for 30secs. after 30 sces, put the battery and adapter back in. then power on the computer and observe.
Both batteries could be dead. But if you bought a new battery, it's unlikely. I don't know what green light you see, but if it's on the power adapter, it just means it's turned on--not that it is charging. Two possibilities: Your power adapter is bad or the motherboard is bad. Because you say the computer works if plugged in, then you have ruled out the adapter. You should be checking/cleaning the battery contacts and if all else fails, going for a new motherboard.
possible when the old AC adapter blew it took part of the power management circuit with it, This is the circuit that detects and charges the battery,
I'm not sure whether this a seperate replaceable daughter card or whether it is part of the main motherboard.
you will need to investigate this (or send it for a service)
