Toshiba A205-S5000 a/c port, lights won't illuminate, no charge
The problem started happening last night when I plugged the ac adapter into the ac port, the lights would flicker but wouldn't stay on. The connector and the battery were cleaned with alcohol and I tried plugging it in again but still the same response, unless I pressed the connector upward then it would stay on or if I didn't plug it in all the way. Today it only flickers. Also I've tried taking the battery out and having the a/c plugged in but it's still having the same response. I haven't even had it a full year and I'm hoping it's not the motherboard. The closest Toshiba repair place is more than an hour away and I was hoping there was an easy solution to fixing this, any help?
Does the plug feel loose? If so that's not covered under your warranty they consider it user damage. You might be able to convince the repair shop though to hide this fact from Toshiba if that's the case. Otherwise they're gonna charge you about $100 for dc jack replacement. Pay close attention to your charge leds.

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,
Hello, If the battery won't charge and the laptop won't turn on but the ac adapter works with other laptops, then the problem is the port where you plugin the ac adapter. Some of the laptops has it built in to the motherboard. So you might need to have it repaired by a technician. Or if the laptop is still in warranty, you might need to send it to the manufacturer to have it repaired or replaced. But if the laptop works without the battery, or it will turn on but the battery indicator is not lighting up, you're facing one of these problems. 1. The battery itself is dead. 2. the battery bay is loose 3. the battery itself is loose Hope this helps
1. It's possible the AC adapter died while you were working on the laptop. The laptop was running until you had charge in the battery and after that it turned off. Can you test the AC adapter? Make sure it outputs correct voltage. 2. It's possible that you have bad RAM module. Do you know if you have two RAM modules installed in your laptop? Try removing them one by one. If one of the modules is bad, the laptop should start when your remove it.
Check battery indicator. If OK, update BIOS. If no change, check battery bios info, if AC Adapter is incorrect, replaces it. Please comment if the information provided has been helpful for the improvement of my support assistance. Thank you and regards.
