I have just been given a toshiba satilite U400 brand new for a new job. When I got it home last night I have tried to charge the battery over night and nothing happens. When the laptop is off the A/C light is on green and the battery light flashes when its plugged in, but when you take all the power out and try and turn it on there is nothing.

POWER SUPPLY & BATTERY PROBLEM If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced. Rechargeable batteries will fail if stored in a discharged state for long periods.
So long as your battery is recognized by your laptop the driver is present. But the problem lies in the charging circuits in the motherboard, it appears it is not functioning, a very rare situation. It is possible the DC jack in the laptop may not be working properly. The computer will need to be dismantled to make that determination and a professional to help.
remove the battery pack and power source. make sure nothing is plugged into the laptop. hold down on the power button for 30 seconds. then reinstall battery, plug the the adapter into a known live power source (the real reason for your problem) and power it up!
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: http://www.mioplanet.com/products/batterymeter/
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. "
You have replaced the battery and then it worked.
Try once with power draining (remove the battery and then press the power button for one minute and then again refix the battery) and check.
It's a motherboard hardware issue in all likelihood.
There is NOTHING you can do but update the firmware bios. The problem is that most bios firmware update programs require both ac and battery power at the same time :(
You can try to do it anyways by visiting Toshiba's support page for your model and downloading the firmware from there.
It probably won't fix the problem but it's still worth a shot....sometimes it works ;)
Remove the battery from the laptop reinstall it and plug in the charger this will start the charging of battery if still doesnot recharge replace the battery
