Battery will not charge up from low (say 0%) while the laptop is plugged in and in use.

Battery will not charge up from low (say 0%) while the laptop is plugged in and in use. The battery will charge if plugged in but  not being used, for example hibernate mode. The machine is a Toshiba Satellite A135, running Windows Vista Home Premium.  The external power supply is 1Liteon N18664, 15 volt. The battery, power supply and motherboard have been replaced.

Check the voltage output on your adapter.  It may be that it is not outputing enough voltage to charge the battery while it is in use.

I have searched Google and found that this is a common issue with this model laptop.

It seems that you are not using the correct power adapter. Make sure that the one you use meets or exceeds the original specifications (the voltage must always be the same).

More specifically, the amperage must match or exceed the original power adapter. I belive the adaptor you're looking for should have the following specs.

65W (19V x 3.42A) 100-240V / 50-60Hz frequency

Sorry, the amperage should be 6.3A .

Correct. The formula is V(volts) x A(Current)= W (Watts)
So you can use the 65W adapter if your original voltage (you should see a label below your laptop) is 19V... You could even use a 90W adapter as long as the voltage does not exceed your original voltage.

He is not using the original power supply or one that meets or exceeds the specifications in current (amps) as I indicated to him in my original (first post).
The original Toshiba external power adapter is 19V 3.42A  and he stated he was using a 15V 1Liteon N18664.
This is why I told him he was not using the correct power adapter in my Comment ID: 30860914. Later when we started getting too technical, I guess we overwhelmed him (which is what I was trying to avoid and ended up having to give him the formula in my Comment ID: 30865257.

Sorry, I made a typo in my question.  I was using a  65W (19V x 3.42A) 100-240V power supply but needed to upgrade to  a 120 watt, 19 volt, 6.3 Amp. to fix the problem.
I'm paying for this service and don't apperciate your wise comments BitsBytesandMore. I was not overwhelmed. I understand simple  power calculation and hold a masters degree in computer science. I wanted to make sure the problem was fixed before closing this question.

There was no pun intended or wise comment. :)
I really was trying to help you and not to overwhelm you with technical jargon. When there is no feedback we can only assume that the specs you are providing are accurate. Feedback is crucial to know your level of expertise and allows us to try to use the level of wording that would be most useful for you.
We can only use the info you provide to help you. Since you stated that you were not using the right power adapter (15V when it should have been 19V) it would have been logical to interpret that your knowledge on electricity was very low, this and the fact that you provided no feedback before of a typo made it easy to misunderstand your Masters Degree in Computer Science.
I was, trying to keep it simple for you benefit, not as a pun, nevertheless, your accepted and assisted answers speak for themselves... Your level of expertise is now evident since, interestingly enough a 65W (19V 3.42A) would have charged your battery while the laptop was in use depending on the model of Toshiba Satellite A135.
I apologize if I hurt your feelings. It is not what was said but what was understood.
Thanks for the feedback.

This model Toshiba has 2 hard drives and would not charge using the Toshiba 65 W standard power adapter.
Simply stated, it works fine now with the new 20 Watt Toshiba PA317U-1ACA Laptop AC adapter.

Thanks for  your help...

Correction that should be 120 Watt Toshiba PA317U-1ACCA Laptop AC adapter.
