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

Laptop keyboard does not work after dog laid on computer


Tell dog to grab it's allowance, and buy you a new laptop

NO?

Then protest around the dog daily until it does

[Hold the dog's chew toy for ransom. Chew on it a little bit so dog will get the message.
"Hey! Ain't kidding around here! Laptop or I keep this!" ]

OR,

Remove ALL power. Remove the AC adapter (Charger), and Battery.
Press the Power On button, and hold it in for a count of 10 seconds.
(And I mean 10. Count; 1001,..1002,..1003,...etc)

Let go of the Power On button. Do this procedure two more times.
Reinstall Battery, THEN reattach AC adapter to laptop, and THEN plug AC adapter into power.

WAIT 1 minute,....turn the laptop on.

My acer aspire 4730Z is not turning ON....battery is down....when am connecting dh charger pin to dh lap, dh green indicator of dh charger goes on blinking. Lap top is like completely dead dat even dh...


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.

I have lost my lead to my acer laptop aspire5100 series model number BL51 19v .474Acan you help.I am a mature age person thanking you Pat


There are two solutions to this problem, Pat.

One is to buy the correct AC adapter (Charger) for the laptop.
Two is to buy an aftermarket AC adapter that will work for your laptop, but will also work for many other laptops.

1) http://www.usbphoneworld.com/acer-adapter-19342-65w-lc-adt01-aspire-5520-ac-acer-aspire-5100-ac-adapter.html?CAWELAID=950033775

The above is from a quick search. Your search may be better. Just put Acer Aspire 5100 charger, in your search box.

2) From another quick search,

http://www.atbatt.com/laptop-chargers/b/acer/m/aspire-5100.asp?utm_source=google&utm_medium=ppc&utm_keyword=Acer+Aspire+5100+Charger&utm_content=NAC-X90-22&utm_campaign=google0&gclid=CLeDr7qIlqsCFQ9S7Aodvn_TXA

Would also like to commend you for your intelligence.
Stating the Voltage, 19V, and the Amperage, 4.74A ,is a really intelligent thing to do.

(The charger MUST have 19 Volts for the Voltage. The Amperage (Amp's, or A), can be more)

For additional questions please post in a Comment.

My acer aspire one ac adapter stoppped charging so I bought a Targus charger and now the plastic around the dc port is melted. Anything I can do?


A short curcuit has caused this problem that is why the AC adapter failed, and it is beyond repair.
I suggest you put your money towards a new laptop.

Aspire One NO turn on at all


You need a DC Jack Repair/Replacement..
your dc jack is the port where your AC Charger plug plugs in to on the laptop.. They can Short out over time and the solder that connects the positive/negative pins burns off which causes the power to short out ... which in turn cuts off power connection to the laptop and can cause motherboard damage if not repaired..

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.

Mousepad


if you want to disable mouse (touchpad), use Fn+F7.
as you said your touchpad create problem, try to remove battery first (boot up using only ac adapter), battery can cause touchpad not working properly.
