First of all, 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.

My Pavilion g6-1b79dx notebook will not charge even with a new battery and charger. The light indicating the charger is plugged in is blinking white


When you say it won't charge, does it charge at all?

1. It indicates that it is charging, but as soon as you unplug the charger the battery quickly or immediately indicates it is dead. If the laptop is off, the LED on the laptop shows it is charging but the battery is always dead,

2. It is as if you didn't have the charger plugged in. No light on the laptop at all when the charger is plugged in.

Possible solutions:

1. The battery has died and is no longer capable of taking a charge. An alternate explanation if you can't even get the laptop to turn on even though the laptop charge LED is on, is that the internal power supply that converts the incoming and battery voltage to all the voltages required has died.

2. The power connector inside the laptop is a common failure point. The solder joints break from various minor shocks over time. This is going to become more common with lead-free solder as it is more brittle. Less likely is that the charging circuit inside the laptop has failed.

What will happen if the battery in your laptop is not fully charging


That would mean your battery is dying and you need to go buy a new battery for your laptop. You can buy new batterys for around $40
Find a store that sells laptop parts or go online look on amazon or next tag also when you get your new battery plugin your laptop charge your new battery so it has a full charge.Then when it is done charging unplug it and use the battery until it dies, then plug it in again to recharge it never leave it plugged in if it is fully charged for long periods.if you are using your laptop at home you can pull out the battery and use it when its plugged into the wall this will help to extend your battery life just make sure you have a fully charged battery before leaving your house. always unplug your your laptop when its is fully charged this will also extend your battery life for along time

My battery is not charging..how will i know if this is damaged??


On a laptop? Does it work with the adapter plugged in to laptop but when it's unplugged the laptop won't work? Battery won't hold a charge any longer. If it's plugged in all the time and never allowed to discharge correctly before being charged again the battery will go bad. If it's an old laptop the battery may just be worn out. My buddy wrecked his battery by never unplugging it for like a year, called HP and they sent him a replacement. Told him to start charging/discharging correctly to preserve the capacity and the life of his battery. Hope this helps.

HP Pavillion 6000 battery issues


Hi Steve, If you haven't gotten any batteries to work properly at all and the problems are different each time, I would say the motherboard is shorting out the batteries and causing weird problems. One last thing to try if possible..

Try a known good working battery, if that battery doesn't work then its verified that the motherboard is bad. If the known good working battery works in that laptop then you got a bad batch and it will be a battery problem.

Since your laptop turns on with the ac adaptor means that the ac adaptor is good.

Battery won't charge


If the battery is not charging, then the charging circuit of the motherboard is bad.

Page 3-22 lists the spare part number for the motherboard. (4 versions depending on options)

Chapter 5 covers disassembly and reassembly
