Laptop does not work with AC adaptor, does not charge. Mother board issue
When I tried to fix my AC adaptor, I think I connected the two wire in opposite way and damaged the mother board. Now the laptop works with a charged battery. Deos not work with AC adaptor. Battery does not charge.
Sent it to Dell. Dell said the mother board needs to be repalced and they charges $500. Did not ask them to fix since with $500 I can buy another new laptop.
Since the laptop works with a battery, I'm thinking connecting a AC adaptor directly to the battery connector (connector on the laptop which connects to the battery) or Or open the battery box, replace the battery cells with a
AC adaptor (At least it can be used as a desktop).
I saw an article about how to open the box and replace battery cells.
I just wondering if there are other better solutions?

Re: Laptop does not work with AC adaptor, does not...
You may be able to get a battery charger but its rare.
If you do wish to use the AC adapter, take care with positive and negative. Also the voltage of the battery is actually lower than the AC adapter in order to get charged. I don't know what is going to happen if you do choose to use AC adapter as battery. 75% chance that it will work.

the problem is in your laptop...maybe it damaged too when you plugged your old adaptor. you should check your laptop for a repair...maybe it needs to replace tha spare parts that may have been damaged.
hello my friend, Im very sorry to hear that, please follow these simple steps for you to be able to isolate the exact problem.
1. Removed the battery. 2. Connect the laptop directly to the power outlet without using the battery just for the meantime. 3. Turn on the laptop. If the laptop is able to power on, that means that the AC adapter is working fine as well as the DC port. If the laptop is not able to turn on, it maybe the AC adapter itself or the DC port. 4. Try to use another AC adapter if possible, make sure that that AC adapter is working fine. If the laptop is still not turning on, the problem is with the DC port itself. In that case, you will need to replaced the Motherboard itself. hope it will help you today.
You could try another battery.But if another battery doesn't work,sorry mate I think it's dead.In future make sure you only use what you know is compatible,also NEVER try to run the PSP with the AC adaptor without the battery in.The PSP safety and support booklet states: Do not use the PSP system with the AC Adaptor when the Battery Pack is not inserted in the system.If the AC Adaptor is disconnected suddenly,it may result in damage to the system.
If it is the motherboard that's burnt out I think you can replace it but they're expensive I think,I saw one for a PSP1000 for
Possible that the battery is faulty. Some Acer models have been found to have very poor battery life due to the quality of the battery that is put into economical models.
So if there is reduction of time in your back up even after the laptop chows that the battery is fully charged, then it is the fault of the battery .
But if there is no charging indication of the battery in the laptop, then the mains adaptor can be faulty.
If adaptor is working then the charging circuit in the laptop mother board has an issue and needs probing .
Must be taken out and checked by experienced hands so as not to damage the main board .
From my experience with 3 DELL laptops, the problem was resolved by replacing the system board. Apparently the port the AC adaptor plugs into becomes damaged (provided you have determined it is not a battery needing replacemnet or a defective AC adaptor) and that cannot be fixed without replacing the whole system board.
Hello All; I used to have these same problems. I replace my BIOS battery, which I know was dead, because all settings get reset when I unplug the power and remove main battery. You might not have to replace it if its still good. Back to the main battery problem, You have a good change of solving this by going into BIOS, and under Tools there is a Battery Calibration option. Do the calibration for the main battery and-or other optional batteries attach and it will most likely solve the problems. This calibration process will take a long time; 1-charge, 2-discharge, 3-recharge, so leave it over night or however.
There was a mention of updating BIOS. This could solve the problem too, because BIOS controls the charging unit. Also, make sure you have Compaq Power Management install on your OS, (download at hp.com).
One note: it will not charge if the battery is about 93% or higher. 93 is not exact, but close to 90%. so test by discharging to below 90% and it will start charging again.
