Question about Computers & Internet
When my Dustbuster stopped working, I assumed the NiCd cells were bad. Upon opening the unit and testing, the batteries are all good. I noticed that the power adapter is 15V AC, which made me look for a diode to convert the AC to DC, but I can't find one. I was able to charge the batteries using a different (DC) adapter and the Dustbuster works fine. There MUST be a diode in there somewhere. What am I missing?

The most common problem on these units is the ac connector solder joints break away from the motherboard. If you're sure the ac adapter is working, and the correct one, and it's not charging the battery (assuming the battery is good), it's most likely the problem. They don't have to appear loose to be loose.
Otherwise, it's motherboard time, or a loose screw, etc has caused a dead short on the board.
Good luck, if you have additional info, let me know.

Hello. There is a hardware failure with the laptop not the AC charger. AC chargers have some range of protections of their own. If the power requirements of the laptop are bigger then what the charger can handle, the charger will turn off. Also other parameters can bring the charger offline. In your case, you have a problem with a small chip, the battery charge controller unit, witch regulates the amount of current required to propperly charge the battery. When this thing fails, the charging requirements for the battery are reported rong and the AC charger is forced to give more power then necesary. This results in disconnection of the AC charger ( an internal fail safe of the AC charger) and the laptop to swich back to battery power. When the laptop is turned off, it can charge the battery because the power requirements are low, having all processor, main board, hard disk etc turned off. Therefore the AC charger can handle the load. However you will need to have it checked by a service center as it is a hardware fault. Both AC charger and laptop needs that check. The charge controll circuit needs to be replaced probably. It will be a somewhat expensive repair. Don't buy any other battery untill you have the laptop checked. For more aditional info please post back. PS. Sorry for my bad english, I am from Romania, it is pretty hard for me to explain tehnical stuff in english.

I've run into this many times with IBM machines. The power management chip on the motherboard has failed. Unfortunately, you will have to replace the motherboard in order to fix the problem.

At the risk of subjecting myself to your possible wrath, I suggest you replace the motherboard. I don't know your computer repair prowess, and am not doubting it for a minute, but I 'stand' here to tell you, that it's just not that simple.
The hardware components are installed down into a bare motherboard. The leads for the hardware components are in their 'raw' state, where they hang down past the motherboard. Then the motherboard is heated up using a hot air soldering method, and the solder flows over the leads making a precise, pretty little solder joint. This is done with robotics. Once this is accomplished, the extra length of lead is snipped off.
Some components are installed by hand. Very few of them. The operator uses a soldering station, and an instrument that magnifies the area by a great amount. Looks like a binocular microscope. One, two ,three, and the next motherboard comes up, and the same part, by the same operator is installed once more.
Again, not doubting your expertise in this area, but if you have use much heat, or linger too long, you stand the chance of making the copper circuit trace, lift right off of the motherboard, when you go to remove a component. Not enough heat, and you can't remove enough solder, nor get the lead to come out of the hole. (I use solder wick. Also known as Desoldering Braid. Solder ****** tools are for the bird's! (Desoldering Tool)
Same thing with soldering a new component in place. Too much heat or linger too long,....well you know what happens. Not enough heat, or staying in position long enough, plus using the right technique, you get a cold solder joint. It's a lot of fun, when you reassemble the laptop all the way, and find this! Guess what happens next? Yep! Do it all over again!
I'm not a saleman for Ebay, but I find a lot of my motherboards for laptops on there. I would also suggest looking at -> Laptops for Parts.

Sorry to hear that you are still having trouble. The only other thing to try is your battery on your buddies notebook. If it works there then it is the charging mechanism on your notebook and this would mean replacing the motherboard.
