Possible solutions for burnt-out circuitry on Dell Latitude D505 mobo?

[Tejapaala]

I have a Dell Latitude D505, recently it disallowed to charge the battery with the AC adaptor. It works fine on the battery. First of all I thought that this may be because of the problem in the adaptor, but after going in depth with this I realized that, there's no problem with the adaptor. I think that this may be the result of the power surge that knocked some of the components on the motherboard. This may cost me more, so I am looking for a cheapest solution here.

You are saying that you do not have problem with the laptop when it is running on the battery, so I would suggest you to go for the external battery charger plus multiple batteries. You are hear for the cheapest solution, then from my side this is the best and probably the cheapest possible solution. If I will find any other alternative I will reply soon. Till then you can look in this forum for more solutions.

I am with a solution but with some risk. Read it, and if you feel comfortable with the idea then you can proceed. If the voltage given out by AC power supply and battery are same then, I would suggest you to solder the wires of the AC adapter to the terminals of the battery. This would give you a permanent power supply. If you want to go with the option of the multiple batteries I will search for the cheapest charger from various sites.

No, I would not suggest the above solution. One of my friend was also suffering this situation. He, took out the battery from the laptop and then soldered the wires from a 12 volt AC Charger to the battery connector. Then he placed the battery in the slot again. He tried to take the reading on the multimeter, the reading was about 12.5 volt which was similar to the battery's reading i.e. 12 volt. Yet the laptop did not turned on. So, really it's upon your risk. If anyone can put light on this I would be very thankful to them. Thanks

I also found myself under the same situation. The laptop that I am currently using just blinks for a second ans then turns off. I went in search for this and from some sites I got to know that the laptops read data from the batteries. It shuts off if the required response does not pop up in time. Yet I am searching for more solutions to overcome this solution. Is anybody else with some other brilliant idea.
