Question about IBM ThinkPad A31 Notebook

1 Answer

Thinkpad A31 2652

Power management shows charging even after power plug is removed.

Charge light stays on when Thinkpad is off and charger power plug is not
connected. This makes me suspect a hardware problem in the charge circuits.

I am equiped to to component level repairs but do not have a schematic.

Thank you,
Mike (retired engineer)

Why does the light fladh green and then stay green even though there is no battery in it!?


If you can remove the battery, remove it.. Wait about 30 seconds+ Then place the battery back in and try charging it again. This is a solution that fixes quite a high percentage of battery related issues.
EVEN works with laptops. Hope this helps. So many other issues could be wrong with your phone or source of power.. Good luck.

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.

My battery charger input


When you connect the power adapter into the laptop, does the power LED light up? If not then -
The battery adapter or the adapter's power lead or the laptop's power socket could be faulty.
Check power adapter’s DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced.
If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard.
This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

Battery won't charge on my ryobi 14.4v cordless drill yellow and green lights stay on


I had the same problem and found a solution on another forum...
Plug the battery into the charger. The yellow and green lights come on. Leave the battery plugged into the charger. Plug and unplug the charger power cord from it's power source a few times until the the red charger light comes on..... problem solved!

I think the "smart" circuit in the charger that is supposed to trickle charge before the regular charge cycle needs at least some battery power to test and start the cycle. If the battery is totally discharged, the test can't deternine the battery status and will not charge.... Plugging and unplugging the charger seems to bypass this teat and charge the battery normally. The charging process should work normally after this method.

IBM ThinkPad - Possible Battery Issue


Some laptops have issues when you run them leaving the battery plugged in. Shut the machine off. Remove the charger, remove the battery. Hold the power button on the machine to disapate all of the residual power. Do this for about a minute. Put the machine back together and leave the battery out. Turn it on with only the power supply. If the problem resets, then your battery is at fault. If not then your charger might be shot or the invertor inside the laptop is fried. Time to get a new one (Laptop or Charger).

read the owners hand book
normally the lights stay red until the battery is charged then it goes green
if the power is cut or if you switch the point off with the charger still in it and do not remove the charged battery , the battery will discharge through the charger

Brand new psp battery will not charge


Did you charge it first? You need a good initial charge. Depending on the charger, it could be about 6 hours.

Also, remove the battery and check the metal contacts on the top and make sure that they are not covered by anything. Some come with a film to protect them.
