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.

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,
Are you using the original charger or a universal replacement? As loose fitting power plug can cause this problem but so can a loose connection at the power jack (repairable) or a cracked trace on the main board from stress at the power jack (not usually repairable - ie needs a new board).
you got a cheap laptop. maybe from walmart or some other store that was selling it for about $400. It doesn't have a processor that you can switch out. I'm sure it's horribly slow for Visa, so my advise would be to sell it and get something with a dual core.
