Hello Everyone.

I have an ACER Aspire 1313LC laptop. About 12 months ago I was having problems with the computer closing down of it's own accord. A friend of mine took it away to investigate. He told me to get him a new battery for the machine as he thought that was the problem. However, if I understand correctly, with a new battery you should first fully charge it, but my friend never bothered to do this. So, the computer worked fine as long as it was plugged into the mains adapter. However, if you unplugged it, it either went to black screen immediately or only lasted a very short time before shutting down. It's been like this for approximately a year.

I now find that the computer won't run at all without mains power, even though it shows the battery as having a full charge. Do I need a new battery or does the fault lie with my charger?

Regards Tony.

While not charging it fully will likely deplete the life of the battery, I doubt that it would be to the extreme that you are describing here.

It doesn't sound like the AC adapter is at fault though, since it runs fine while plugged into the adapter. Can you run the computer with the battery removed? If so, then your AC adapter is running fine.

What if you turn the computer off and allow it to charge fully, then remove the AC adapter and try to turn on the computer, will it allow you to boot, and if so how long will the charge last?

I'm assuming that means you are able to run it with the battery out of the computer just using AC power? If this is the case, your adapter is fine and your battery is not holding a charge at all.

no- it wont run with the battery removed it will only run with the battery in with the AC connected. It indicates a full charge but if you remove the AC it either goes black screen or shuts down completely

Something sounds screwy. It almost sounds as if they're both faulty, but I wouldn't know where to begin. If it's not running on AC power alone, that usually means that your AC adapter is no good.

Let's take a look at your power saving settings. Open your power settings as described for your operating system below. Make sure that when you're on battery, it isn't set to shut off monitor immediately or something screwy like that.

I have seen this problem before but usually if you plug the computer and remove the battery it works fine, and that would be the battery that is faulty. Anyways I'm a big fan of desktop computers because they have longer life spans. A laptop lasts only 2 to 5 years, but a desktop can run for 10 years.

True story. I still have my desktop from 2003, and the only reason I'm thinking of replacing it is that the power supply died. It's only a ~$40 part, but I'd rather not put any more money into a computer I'm gonna wind up replacing in the near future anyway.

It's very strange that neither are working independent of each other, but with the battery and AC adapter it works. I've never seen this problem before which is why I suggested checking the power settings. Maybe he has it set to turn off after ~1 min on battery or something and the battery is really fine.

Yes, I have tried everything but nothing seems to work. The most annoying thing is if I forget to connect my power supply before switching my computer on it will start to boot up but I can't see the screen - it's just black. I can see it very faintly but I can't really make anything out. It makes no difference if I then connect the charger although it shows it's connected and charging. I have to switch off then restart with the charger connected. Once on if I check the battery status it indicates a full charge. I think I am going to have to accept it as it is.

Thanks and regards

Tony
