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.

Hi Chris,
Thank you for your reply. The answer was in the ta7i0v600 readme.txt. I thought I would like to share with everyone.
1. The BIOS title “ACPI Flash BIOS version 6.00 for Tecra A7 (Intel) (PTA70U) is miss leading. After extracted I opened the readme.txt contains a list of models that this BIOS supports.
2. In the Caution! Section, Here is the copy of the mystery of how I solve my problem: “On some models, it is not unusual to see a CMOS checksum error when you first reboot the computer after installing the new BIOS. If you see this message on your screen, press F1 as instructed. This displays the “TSETUP” screen. Press to save the CMOS data. You won’t see the CMOS checksum error again.
3. If step 2 still not working for you. After you flash the BIOS, turn off the power to the computer. Holding down the tilde (~) key on your keyboard and turn on the power. This will boot up to drive A. [This still is mystery to me, I do not have drive A.] Than do step 2.
Luckly, my motherboard is fine, my CMOS battery is fine too. -Seaberry

osman,
Most likely the battery is bad and has to be replaced.

umair,
Could be bad AC adapter.

Amanda,
Probably bad AC adapter. The adapter died while you were using the laptop and the laptop works until the battery had charge. Now the laptop will not turn on because it’s not getting any power from the adapter and the battery is drained.
Test the AC power adapter with a voltmeter, if you can.
Try replacing the AC adapter with a new one.
It’s possible the dog damaged the adapter cord.
You can try replacing the AC adapter yourself. If it doesn’t fix the problem, you’ll have to take the laptop to the repair shop.
