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.

Elena S,
Could be bad battery or bad motherboard. The only way to find out witch one is bad is testing the laptop with another known good battery.
You can use the laptop until the motherboard fails completely.

i m using a toshiba satellite A100.when i push the power button my laptop seems totally dead,abosolutely no led activity is shown.today i took it to a service centre and they told me that it might be a motherboard problem.and they took out the battery and now i can only use it only when the power source is AC power.and i cant use it even from the AC power source if i have the battery connected to the laptop.
can anyone tell me how long i can use it with a faulty motherboard?:(

Shane,
If you still have the same problem with new power adapters and different batteries, apparently you have something wrong with the motherboard. I cannot tell you what is wrong, but most likely it’s related to the motherboard.

I have a Gateway 450SX4 I have been trying to fix now for about 3 weeks. I have searched and read about every page on the internet and not found any solutions yet. It will not charge the battery. Here is what I have tried so far. Power adapters. I have a brand new name brand 19v 90w (4.2amp I think) tested power adapter hooked to it. I have tried several but Im currently using this one. It has an up to date BIOS. I have had a new power jack solderd on the board. The light on front turns amber like it is charging and after about 5 min it turns red. In the power management software it says “online discharging” 0%. After a day in laptop charging I pushed the little button on the side of the battery and no lights. Battery is dead. In the BIOS I tried the battery recondition thing (Smart Battery Auto-Learning). After 5 min it tells me “Battery Malfunction cannot get battery model”. I bought another battery off eBay and tried it. I got the same results. I found a secondary battery that goes into where the cd-rom goes. I thought maybe something was wrong with the place where the battery normally goes. It sees the battery, knows its a secondary battery but gives me the same results. I checked the pins in the battery compartment with the adapter plugged in and im getting 3.2 volts. Is this the normal volts going to a battery? Did I some how get lucky and end up with 3 bad batterys that were supose to be good? Do I have a bad charging circuit? What am I missing? Thank you for any help on this. Shane

Miguel Morales: the code mentioned states that the P1.8V supply is below 1.44V during boot-up. So, the processor will NOT operate.

andy,
When you purchase a new power adapter for your laptop you should follow this rule: The voltage output on the power adapter should be exactly the same as required by the laptop. If your laptop requires 15V, your new adapter should output 15V. The current output on the power adapter should be the same or higher. If your laptop requires 5A, your new adapter output should be 5A or higher.
Personally, I don’t like all these adapter with adjustable voltage. For some reason, I don’t trust them.
I cannot tell you what is wrong without testing the laptop with another known good power adapter.
1. Could be bad power adapter.
2. Could be dead battery.
3. Maybe the battery charging circuit (integrated into the motherboard) is screwed.
Also, make sure you have the latest BIOS installed.
Just in case, you can find a new AC adapter if you search using the part number V000061220 or V000061210.

I got a Toshiba A 105-s4211,
The power adapter for my laptop got burnt and screwed up,
i found another charger from the market with similar specifications but different models, however it has screwed my battery,
now, it doesnt charge my battery, when the laptop is powered on, the power options sections shows the battery as charging but then there is this red cross line on the battery secton as well.
i also expereinced screen flickering problem after i bought this new power adapter,
is this an adapter problem or is my battery charging kit become malfunctioning?
i bought another chinese charger that allows to laptop to be charged in car as well as on aeroplane, this one is a multiple charger and has various options to adjust voltage input, but the current input is 3.75A while my note book requires minimum 5A,
does it matter?
i want to know, if my battery is screwd up or if the battery charging kit is scewed up , and will it help if i get a new battery and a new charger.

Hello,,
it seems that the charging electronic kissed goodbye,,which Means,, “Malfunction” So, in this case you must send your Machine to an ASP ‘Authorised Service Provider’ for a hardware checkup and repair of that component.

Mark,
To me this sounds like a problem with the motherboard.
