Question about Acer Aspire 5100 Notebook

Replacement AC Adapter causes touchpad problems

I have an Acer Aspire 5100-3949 (out of warranty) and my dog chewed into the AC adapter/charger thereby creating a small break in the wiring. It will still function somewhat if wiggled but I also have had arcing thereby making it possibly dangerous to continue to use.

That being said, I have tried to purchase replacements from sources like EBay and had each seller confirm that it was compatible with my specific laptop.

I have had to return them because they made my touchpad act erractically (i.e., cursor not responding, cursor only moving in certain directions, etc.) however once operating on either battery or original adapter the touchpad acts normally.

I have checked Acer’s website and the model adapter/charger that seems to be compatible is out of stock.

Any ideas on what would cause this behaviour and what to look for, in terms of specs, to attempt to avoid the problem on the next purchase.

Thanks in Advance,

OK here is the problem your laptop use a certain amount of power to is parts to operate too much power from the adapter causes glitches where as the mouse pad would freak and stuff or certain keys not functioning so you have to look at the old acer adapter u have and make sure it has the same amount of MA = mili ampage to the universal one your thinking of purchasing also the same amount of imput and output voltage and if not too certain carry your laptop to the store and try the one that they have

Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help:
Possible causes:

1. AC adapter failure.
2. Power jack failure.
3. Motherboard failure.

Possible troubleshooting steps and repair solutions:
1. Test the AC adapter with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.

2.It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one. Using a multimeter, test if the power goes to the motherboard through the jack.

3. If replacing the AC power adapter and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

The solution to your problem lies in one of the following three areas:

1.) Your charger is faulty and is therefore not able to pass power to your laptops battery.

2.) The charging connector on the laptop has come loose from the contacts. Therefore a bad connection.

3.) Your battery is faulty.

I think possibility 2 is the most likely, although you will have to test possibility 3 by removing the battery and plugging in your charger and seeing if the laptop powers on.If it does power on then that rules out possibility 1 and 2 leaving a faulty battery.

If you need to buy a new laptop charger, the following to adapters are for your reference:

2 ac adaptors have stopped working on acer laptop


Take the battery out. Unplug the charger from the computer. Press the On button for 30 seconds. Then plug the charger in. If it works, then put the battery back in and you're in business again.

If it still can't work, perhaps the charger you bought is a dead one, just contact the seller to get a replacement one after all you have used it for about a few minutes. If you don't believe in that seller, just contact them for the refund and go to other vendor for a new adapter. I recommend the following one for you:

My laptop touchpad doesnt work properly when i charge my laptop.


If your new adapter is not compatible with your Acer Aspire in voltage and current, your laptop maybe can't work well. Check your new adapter and ensure if it is the same with the original adapter.

Replaccement AC adapter charger issue


If you used electrical tape and firmly wrap the tape around, your cable should be secure enough to continue use. Just be careful around your dog.

I hope this helps address your problem.
