First, you need to make sure your power adapter is providing enough power to both run the laptop & charge the battery. A very good way to do this is to compare your laptop voltage & ampere requirements (written on a sticker on the bottom of the laptop) with the voltage & ampere ratings of the power adapter. Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amperage of the power adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating, or else the power adapter will be providing insufficient amperes to charge the battery. Of course, the power adapter's nominal amperage might be ok, but it degraded on usage. You can verify this by testing using a good or new power adapter.
If the battery did not charge using the new power adapter, take the battery off the laptop, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the laptop & try again.
If this still did not resolve the problem, then the battery itself could be bad. Try it on another laptop, or try a good or new battery in your laptop.
If this did not work, there might be a possibility that the charging circuitry on the laptop's motherboard is defective & needs servicing. In order to do this, the laptop needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether.

My battery charges but only lasts about 20 minutes once it says it is fully charged. Just purchsed a new battery thinking it was old (laptop is about 3 years old) and the same thing happens.


From what you describe and assuming the new battery was "new", I'd say you have an internal short which is draining the battery over a short period of time. I'd also investigate the accuracy of the battery charge indicator. Download this free utility which will give you a more accurate picture of your battery:

I'm assuming you gave the battery a "commissioning charge" when you bought and used it?
If not, this is something you should do with all new LI batteries. This bit is reproduced from a website that sells batteries for the Toshiba satellite series:

"2. The new Toshiba Satellite a205-s4777 battery pack needs to be circled (fully discharged and recharged) three to five times to reach its optimum performance.
3. Toshiba Satellite a205-s4777 battery will undergo self-discharging when left unused for a long period of time. Thus, it should always be stored in a fully charged state and kept in a cool, dry and clean place.
4. It is normal if the new Toshiba Satellite a205-s4777 battery gets warm when being charged or used. However, please pay special attention if the battery pack becomes excessively hot. This may indicate there is a problem with the charging circuit of the electronic device. Please consult a qualified technician if necessary.
5. To maintain the optimum performance of Toshiba Satellite a205-s4777 battery pack, it is highly recommended to circle (fully discharging and recharging) it at least once a month.
6. New batteries are hard to be charged. Sometimes, your electronic device may indicate a fully charged condition about 10 to 15 minutes when Toshiba Satellite a205-s4777 battery pack is being charged for the first time. When this happens, remove the battery pack and let it cool down for about 10 to 15 minutes then repeat the charging procedure. Sometimes, the new Satellite a205-s4777 battery will suddenly refuse to be charged. If this happens, a suggested solution is trying to remove the battery from the device and insert it again. "

Toshiba Satellite a205 Battery Will Not Charge


You did what all should not have been done. your battery works as a buffer between high surge of electricity which comes through electrical supply i.e. it protects your smps from burning up. From your current position it seems your smps fuse has blown. If they have given one or else your smps itself has gone. I'll tell you for your future usage of battery. Whenever you get any electronic equipment with chargable battery you should never switch it on unless and untill you have charged it for continuous 24 hours. Never try to run such equipment directly through dc or ac power. Hope your fuse has gone its not costly.

My Toshiba Satellite A205 Battery


Laptop's battery is IC controlled. Circuit will stop the current when battery charged enough. So Battery will remain unused. However its also could be good idea to release the battery and keep dry place if you are using the laptop permanently stable AC power. If you need further assistance post your question.
Good Luck
