Battery does not charge and does not provide backup power
I tried to power my Toshiba Satellite A205-S5000 notebook with an un-recommended more powerful battery. I must have blown something on the board, 'cause since then I cannot power the system with the battery even though the system indicates that the battery has 22% power.
Also the system indicates that the AC cord is plugged in and the battery is charging, but it does not rise past the 22% power indicated even after several days of charging.
I've used the battery to power another system with no problem.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Try another cord/charger with the EXACT same power specs. If you have a multimeter, verify DC voltage at the AC jack plug. If the AC jack, in the laptop, has been pulled, damaged, it's may have a loose connection. You didn' say if ANY LED's, battery charge, work? If the battery is charged and it doesn't start on battery only, then you have other issues. It may need a ride to a Qualified Computer Tech.
So................... 1) Am I to assume someone broke the female connector on the motherboard, that the DC Power Harness used to plug into?
Hard wired in this statement would reflect there was a DC Power Harness, soldered directly to the motherboard?
2) Or is your statement that the DC Power Jack itself, for your model; is soldered directly to the motherboard; and you hard wired the new jack in place; after cutting the plug off of the end of the new DC Power Harness? (And removing defunct DC Power Jack)
Plus; Is this an A205-s5000, or one of the A205-s5000 model series? A205-s5800, A205-s5801, A205-s5803, A205-S5843, etc.
Trying to figure out why this A205, has a DC Power Jack soldered directly to the motherboard, and is not using a DC Power Harness.
Have to make sure you are soldering to the right area, yet alone the correct contact points.
Don't know what I'm talking about? You unsoldered the DC Power Jack FROM the motherboard? Or the jack was soldered to wires, and wired to the motherboard. Hardwired. The term can be used for either scenario. That's the way it was originally?
Let's go on.
The DC Power Jack is connected to the DC to DC power circuit; on the motherboard. (Power/Charging circuit) This circuit is near where the DC Power Jack is mounted, or where the DC Power Harness plugs in.
In the circuit are Surface Mount Devices that are prone to go bad. One is the Power MOSFET's, the second are MLCC's.
(Multi-Layer Ceramic Capacitor. They, and the P.MOSFET's, are SMD/SMT Surface Mount Device/ Surface Mount Technology)
These series of Notebook PC's use the; Fairchild Semiconductor International - FDS6679 - Power MOSFET, and the, Alpha & Omega Semiconductor Limited - AO4407 - Power MOSFET.
Look at the second photo down, with the AO4407 circled in Yellow. Immediately below it, (Right corner), and immediately to the right of the AO4407; are MLCC's. Smaller rectangular object with a dark wide band in the middle of it.
There is one above the one, to the immediate right of the AO4407; one above it, one to the Right of the top one; and one to the right of it. There are also 4 smaller examples to the bottom/left corner of the AO4407.
Look to see if any are burned/blackened.
Example of availability, and cost of FDS6679, and AO4407,
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.

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
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. "
First check wheather battery is dead . Charge it completely and also check the lights while charging.
If you think its battery issue try the following remove the battery and then press the power on button, it help release and electricity left then place the batter back . and Power it on.
If the lights just blink then...press and hold the battery button for force a shut down then power it back on.
