I have one or more problems with my power supply and/or battery charger. Here are the symptoms:

1) When I plug my computer in to the wall, the Wall Power LED at the front of my machine lights up. If the computer is not powered on, the Battery LED _usually_ lights up as well. However, if I power on my computer, the Computer Power LED lights up but the Battery LED usually turns off. (This is new -- it never did that before this weekend).

2) If my computer is plugged in, turned on, and the Battery LED is off, the computer is _not_ actually running off of wall power but is instead running off of battery power.

3) If I remove my battery, plug in my computer, and start up, it runs for a while (apparently on wall current), before turning off unexpectedly.

4) There is apparently a loose connection between the power socket on the back of my computer and the computer power supply: Sometimes when I plug my computer in, the Wall Power LED _won't_ light up until/unless I wiggle the cord where it plugs into my computer.

If anyone could help me with a diagnosis/treatment, I'd appreciate it.

I had the same thing happen to me. I returned the PC for a new one.
For future reference if your laptop starts to turn off unexpectedly, this is due to a overheating issue.
I have to send my PC back to see if they can fix this.

I have exactly the same problem with exactly the same machine. I am using your description in dealing with Toshiba. I have been told the problem is because the machine was dropped but it worked fine for monthsafter that when it just started to act like stated in OP.

Just for heads up... I found out what the overheating problem was. Apparently my system got clogged up with dust (Told my woman to clean.. I'll deal with her later) Kidding : -P Seriously folks.. I was told that if I purchased a small can of air to blow through the heat sink on the back of the laptop, my system would not have overheated, and shut down like it was doing on a continuous basis. I was lucky to still have a warranty so it didn’t cost anything but time away (one week) away from my Laptop.
Now I Blow my machine at least once a week (Geez that doesn’t sound right) after I shut down.

Yeah, we had the dust problem first. Then we learned to blow it and the computer ran great for about 6 months. The we started having the problem exactly like discribed in the original post. I can't run it off the AC adapter because as soon as I turn it on it switches to the battery. But since I can't get it to charge the battery -- either while using it or while it's turned off -- I basically can't use the computer. Sometimes I can wiggle the plug juuussssst right and hold it there and, if I don't move for an hour or so, I can charge the battery long enough to run it for a few hours. But usually my hand cramps before that. Or the phone rings or something.

I'm sending it back to Toshiba and printing this thread out to send with the computer to explain what's happening. I'll let you know what they say.

I'm late in posting this because I went on vacation. Sorry.

I sent the laptop back to Toshiba with a detailed explanation of all that has happened with it -- including it falling, our trying to open the back, the dust accumulation that caused it to shut off which we thought was damage from the fall, and the failed attempt by one of their authorized repair shops to jerry rig a repair because they refused to contact Toshiba. As I said I would, I included the posts in this thread.

Within a week of my sending it, I got the laptop back completely repaired with no comment. I have no clue what was wrong but the AC adapter now fits much tighter in the DC-IN on the back of the computer. As far as I can tell, it is not my original board or my power cable/AC adapter. It now works great. I almost think there was a wrong part somewhere.........

I am very pleased with Toshiba.

Seems like they just didn't do a stress test on where the power plugs in. They should really hang their QA department for that.
I was lucky enough to discover that issue within a few days after buying my laptop. I was able to return it for a new one. I've owned this one now for about a year and I Plug & unplug the power from the back of my laptop on a daily basis (at least 2 or 4 times a day) and I haven't had a problem with the power as of yet so there is hope.
One thing I will warn people about, If you are a gamer and you are looking for a Laptop to Run Games such as, Need for Speed, Doom3, and hundreds of other high graphic games..."THIS LAPTOP ISN'T FOR YOU"
The graphic card is shared and cannot handle the stress. This might sound trivial but it is information, which I would've loved to have prior to buying this PC.

Hi guys,

I have had my Toshiba for just about a year, and about 2 weeks ago it started developing the exact same problem described here with the AC adapter and the laptop not switching from battery to plug. I check out the power supply and I know it is in good shape, so I know it is an internal problem. Has anyone else found any other solutions, or others having the same problem? I am just a bit hesitant in returning it to Toshiba for repairs,
(I have been burned a few times) but that may be the only solution.

Thanks !

I had the same problem and was told by a factory authorized repair center that they have seen alot of the a-70' and a-75's as well as some M series come back for the same problem. He told me the repair replaces the board on which the power connects to and it was basically reinforces the plug. I had mine repaired and back in my hands in about a week no questions or problems. I live near the repair center so I didn't have to send it anywhere. The service was performed at PC Universe in Boca Raton FL. They were pretty good about the whole thing.

I have same problem with my Toshiba P10-804. It is beyond the warranty date. I no longer have my original power supply because a few months after I purchased the unit I upgraded the BIOS to version 1.5 - this was causing the HDD to power-cycle 5 to 10 times per minute. I complained to Toshiba about this and simply asked them to send me a 1.4 BIOS, but instead they took my machine for a week and swapped the Toshiba Power Supply for another one with lots of foreign writing on it.

Never the less, it was only about 2 weeks ago that this problem first surfaced. It's very annoying. Do not know if this is relevant, but I have found that when the battery LED goes out, this results in the Power Management app saying "Power Source: AC Power" and "Battery: x% (discharging)".

I have also discovered that even if I don't move the unit and then just restart Windows, the battery LED will come back on again (most of the time without even having to wiggle the AC connector).

Very annoying problem though...

This is a known problem with these models of laptops. The problem is faulty boards. And there was even a recall on these laptops (which I did not hear about either - but there was). I took mine to the local repair service and had it back in a few days. No problem so far. Of course, they knew the issue right away, and replaced the board.

I've had the same problem from day one with this laptop, and it does seem to be getting worse. Since I just passed the warranty expiration date, I decided to open 'er up and have a look. I found this web site: http://www.irisvista.com/tech/, which has step by step instructions for opening up the box, with pictures. However, it is missing an instruction to remove the two F3 screws inside the battery compartment, and the pictures are not real great, plus it doesn't tell you when reassembling, which screws go where (there are three different lengths of screws, but all the same size/thread pitch). What I found when I got to the power jack, is a poor design on the jack itself. The ground side of the plug, which is the outside of the barrel, conducts through a thin piece of sheet aluminum, which does not appear to be electrically connected to the thin piece of sheet aluminum which is electrically connected to the circuit board. It appears as if the two sheets move against themselves, but there is no definite connection there. I tried hitting it with my soldering iron to solder these two pieces together, but wasn't successful. So, I soldered a couple wires which I ran out through one of the ventilation holes to another, better connector, but that doesn't work for some reason. I'm still trying to find a good solution. Last week, the local repair shop told me the price for a new motherboard is over $700 - probably not worth it. I'd be happy with a newly designed connector which I'd install myself if I could find it.

So, it seems there was more to the problem that what I posted last night. I dug out a magnifying glass, and it turns out that the +V wire coming out of the power jack was not soldered to the motherboard completely, and this is what was causing the intermittent power connection. I soldered a jumper wire from the back side of the jack to the side of the chip right behind it, and my connection is now very solid. I just wish I had done this a year ago! So, if you're brave enough, and have a decent touch with a soldering iron, this alteration is probably not outside of your capability, and if you had the same problem, try this; you might like it.

Here's a Toshiba Satellite A75 disassembly guide.
http://irisvista.com/tech/laptops/ToshibaA75/satA75_1.htm
Mike Jesch wrote that pictures are not really great, and that I missed to mention 2 screws in the battery bay. When you click on the picture, you'll get a bigger one with all screws marked.
Good luck.

Heads up to everyone on here. My PC just started shutting down on me again for no apparent reason. I wasn't running a memory intense program, I had plenty of disk space and the machine was only on for less than two minutes so I can't see how it could overheat in that short of a period of time. The good news is I haven't had any problems with the power supply since I had it fixed last year. Does anyone on here know of a diagnostic program that will run in the background that can tell me the last thing my machine was doing before it shut off? This will help me in tracking the issue at hand and I can share my findings with the group.

Thanks,
Jerry

hi Mike,

you mentioned you could fix the power connection trouble by soldering extra wires. Could you post some pictures or explain the procedure a little bit. Looks like everybody here has the same problem and a replacement motherboard costs too much. your solution could save plenty of money for everyone :)

Appreciate your help.
thanks,..

It happened again to my machine 5 month later. Even though it is now off warrenty Toshiba is going to fix it because their fix under warrenty didn't take. Just talked to the tech at the nearest authorized repair center; she said they got info in October about some models, doesn't know if mine is one, but the system board problem might be fixed now. Well see.

I think part of my problem is that I use the computer on my lap, not on a table. I think the weight of the unsupported power cord could be a problem. People who use their computer on a table with the power cord supported might not have the issue show up as quickly. Just my guess......

I'm having the same problem with an A75-209. With the factory power supply that outputs about 19.6V, the PC will charge the battery untill I start to perform any functions, then the charge light goes off and the PC operatesoff of battery power only. With a new Kensington power supply from Best Buy that outputs 18.7V, the charge light will never come on while the PC is on. So I took out the motherboard to do some tests. When I turned the motherboard on the voltage dropped to about 18.5V with the factory power supply. With the Kensington the voltage dropped to about 17.5V. I have a feeling that some problem with the motherboard is pulling the voltage down to a level that will not power the PC. I would be interested to know if anyone else has recorded similar voltage drops on the mother board. I was taking the measurements from the V+ and ground connections on the power connector. I tried the "Jumper wire" fix posted earlier but it was with a very small gauge stranded wire. I'll try a larger solid core and see if I get better results.

Since you found a way to solve the problem, it will be a good idea to post a picture or at least a drawing (if you dont want to open laptop again) of the process. That should help a lot of us. Please consider doing that.

Well, I did what you (Mike Jesch & R Warner) claimed would work, but I'm not sure it did or maybe I did something wrong... I did take some pictures of the motherboard and the fix, maybe you can tell me if that is the way it was supposedly meant to be done (http://www.saiec.org/tmp/front.JPG http://www.saiec.org/tmp/front_close_up.JPG http://www.saiec.org/tmp/back.JPG http://www.saiec.org/tmp/back_close_up.JPG). In fact my laptop is kinda working right now, but even so the lights refuse to function properly, I wonder if anyone else had this problem after fixing their laps. Or maybe my computer is just randomly working and I didn't fix a thing... any help?
