Today I got Toshiba Satellite A105-S2712 for repair with the battery charging problem. It is a new model and we do not have a lot of experience with these laptops. The customer complained that the laptop will not charge the battery when it is plugged into the AC outlet.

The laptop failure symptoms:

The laptop will not turn on when I try to start it from the battery. When the laptop is turned off and plugged into the AC outlet the battery charge LED doesn’t light up. I know that the battery is not charged and the LED should light up when I plug the laptop into the AC outlet. The laptop starts fine when it is plugged. When I move the mouse over the Toshiba Power Icon in the lower right corner, the balloon will pop up and there is a line in there: Battery Remaining: N/A.

The problem repair procedure:

You can easily fix the problem just by updating the BIOS. Toshiba says that the BIOS version should be at least v1.30. So, go to Toshiba website and click on Downloads. Select your laptop model and find any downloads for the BIOS. In the BIOS change history you will see the description of changes.

After I updated the BIOS, the battery charging problem disappeared.

    Ryan,
    If I understood right, there are no LED lights at all, but the laptop is making a clicking sound when you plug the AC adapter (even though there are no LED lights), right?
    I don’t think this is a problem with the harddrive disk. When you have a faulty harddrive disk, you still should get LED lights when you plug the adapter.
    Try this. Remove all extra devices you can access from the bottom – battery, DVD drive, harddrive disk, memory cards and plug in the AC adapter. If you still have no LED lights and the laptop is still making the same clicking sound, probably you have a bad motherboard.
    Here’s one more thing to try. Find a voltmeter and test the AC adapter. Make sure it outputs correct voltage. I think it’s possible that you have a bad AC adapter and it doesn’t provide enough power to start up the laptop. This is just a guess.

    Great Site,
    I have an A105-S2716 that has been working flawlessly for the past year and 1/2. I was working on it last night, left it alone for a couple of hours and when I came back the screen was black, it was shut down and no LEDs. Now it will not boot up, still no LEDs, but when the AC adapter is plugged in I can hear a very faint clicking sound that is coming from the general area where the fan is located on the bottom. It will not do anything when the power button is pushed. I tried vacuuming it out with no change. Does this sound like motherboard or hard drive failure? Or maybe something else.
    Thanks For your help.

    Sigh….

    Can anybody recommend a good do-it-yourself kit (like does radio shack sell the kit so I can make my own crappy computer?)

    apurwanto,
    If I understand correctly, your laptop runs fine from the AC outlet when the battery is removed. It also runs from the AC outlet when the battery is installed but the battery will not charge. Is it right?
    I think you might have a bad battery. If a new battery will not resolve the issue and you still cannot charge it, there could be something wrong with the motherboard.

    Scott,
    I would make sure the laptop runs the latest BIOS version. Upgrade the BIOS if needed, it might help to resolve the issue without sending the laptop to Toshiba. If the problem is still there even after upgrading the BIOS and your laptop is still under warranty, then I would suggest sending it to Toshiba. Make sure to make a good note about the problem you are experiencing and include it with the laptop.

    I’m having the same problem as Carol with my M105, I think. One additional complication that I have is that sometimes when the power cord is unplugged or “unplugged” from the computer, the computer doesn’t register that. So even though it’s getting no juice, it doesn’t use any power saving techniques and just runs through the battery really fast. I would think that you were right with replacing the socket (since jostling the cord around seems to make it charge), but that doesn’t explain this other problem, which started at the exact same time. Should I just send it back to Toshiba, you think?
    Thanks for the help.

    Mauricio,
    It’s hard to guess what is wrong with your laptop but in most cases a blinking amber color power LED indicates a problem with the motherboard.
