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)

Nc6000 multibay battery does not recharge


Perhaps remove the multi-bay battery, and let main battery charge all the way. Then reattach multi-bay battery, and see if it's recognized.
(Will charge)

That is AC adapter (Charger) removed, then remove multi-bay battery.
Plug AC adapter back into laptop, THEN plug AC adapter into power.

[You do Not want to unplug an AC adapter from a laptop, with the AC adapter plugged into power. Could be a power surge/voltage spike. Unplug AC adapter from power, when plugging into laptop, or unplugging from laptop ]

Main battery charged, unplug power to AC adapter, unplug AC adapter from laptop. Plug multi-bay battery in, then AC adapter.
(Then plug AC adapter into power)

Dell inspiron M5030 won't charge, green light is


This is a common problem. It may be that the charger is dammaged. these Dell chargers have a micro thin communication cable in them that tell the charger to charge the battery. this micro thin cable can often break. Its use it to prevent the laptop battery from over charging, but if it breaks or becomed broken inside tha charger cable, then the laptop simply won't get the charge signal and the battery won't charge. If this is the case, then you will need to replace the charger with another Dell charger compatible with your laptop

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.

My laptop won't charge when plugged in...I changed the charger but still won't charge


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,
Or:
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.
Or:
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.

T20 batteries wont stay charged


It might be that you are using older batteries. However, you should try dimming your backlight to the lowest possible setting and performing any other power-saving actions such as limiting the processor's power (if available on your laptop.) Hope this helps.

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).

X41 Tablet PC the battery shows good but computer will not work


Some times a battery can pickup a dead short, and even though it shows a charge it will not work. The other possibilty is the power management chip on the mother board. This chip allows the computer to charge the battery and switch from battery to AC. (Right now I have a Thinkpad that will only run on battery, bad PM chip) Try replacing the battery first, if that doesn't work, then unfortunately the motherboard will have to be replaced.
