Notebooks & Netbooks

[Kiran1]

My Acer Aspire 7750 notebook would not run off of the battery; it runs on the A/C power only. As soon as I remove the A/C cord the notebook shuts off completely.


When running on A/C and the battery is in the meter shows 100%. If I remove the battery (with the A/C still on) the battery meter indicates no battery detected. This tells me the netbook is recognizing the battery (at least as far as charging is concerned).

The battery led is blue and when I plug in the A/C cord the led is lit up blue.

I did a system restore back to the factory settings and that did not solve the problem.

Everything else works fine and there are no error messages when booting up.

When the A/C cord is unplugged, the notebook will not start on battery power.

Now I have a netbook that I can not use unless an A/C power outlet is nearby.

Could you please advise me on what to do,as I am really disappointed, this is my first acer product that I have purchased..please help. Thank you

Hi Kiran1

Is the charger the original one that came with your laptop? Sometimes, replacement chargers won't charge the battery if the voltage is wrong. Or it may be that the battery has completely failed. If you take it along to your local PC store, they can check it for you by using a multimeter.

If the battery is dead (or close to), then it will be time to replace it.

Hello finlux..thank you for the response..the charger is the orignal 1 that came with the laptop..the battery after a few days goes down to 95% and chargers back to 100%..but as soon as unplug the ac charger..the laptop goes off..the battery is charging,everything works on the laptop..it just won't work on the battery..should I try another battery?..I could buy 1

Yes, I'd definitely buy a new battery, it should solve your problem.

Let us know how you get on!

Ok..thanks..will order 1..will update you once I get it..

If you are still in warranty your battery will be covered, there's also a chance that the power board is the issue. If the battery doesn't fix the issue and you're out of warranty I may be able to help. Hopefully the battery will take care of it though.

And long time no see Finlux, hope your new year is off to a good start!

Take care,

ScottyC

Kiran, it is possible for a laptop to recognize a failed battery and think that it is fully-charged. You probably need to buy a new battery.

Try the Universal Laptop Cure, guaranteed to work 10% of the time. Remove the battery and power cord and hold the Power Button down for one minute. Put it back together and try it out.

Another cure is to start up the laptop and then remove the power cord to get the battery kicked into life.
