    You will need to replace the motherboard

    I checked with a new battery, but the problem remains. Could it be some hardware issue as what the local repair guy was suggesting?
    Thanks

    Hi, I have just read your thread and am having exactly the same problem with my Acer Aspire 8920g. Have you had any luck because if you have sorted it I would like to know how!

    The motherboard is bad...

    Hi,
    Thanks for the reply. Why, if it runs perfectly well on the battery is there a motherboard problem. Also I have a new ac supply and a new battery which would not charge which I returned. Same problem with the new battery. The old battery which is on its way out still charges up.

    The motherboard also has the AC input circuits to change the AC to DC current for use in the laptop like the battery supplies. These AC input circuits on the motherboard are damaged

    In the case of laptop batteries it's worth considering a possible complication where the computer manufacturer has taken steps to make it very tricky to install a cheaper replacement unit from a third party supplier. I haven't much experience with laptops but am acquainted with this in the now discontinued range of Sony Vaios.

    Apologies for simply posting a link but anyone with a Dell laptop might be well advised to look into this. It's a pretty involved issue and typically the computer manufacturers' tech support are unhelpful. Unsurprisingly they want to tie consumers to their expensive replacement parts.

    It seems that there are problems with Dell laptop batteries. I wonder if anyone has had problems with Acer batteries as this is the second new battery that won't charge yet my old battery will?

    Quality control on batteries is not the greatest. Even with the major manufacturers’ own batteries there have been issues. I believe that the last lineup of Sony Vaio laptops sold earlier this year have issues with their batteries.

    If a laptop keeps turning itself off it is more likely to be a motherboard issue. Unfortunately taking a laptop apart and fixing it is a difficult and time consuming business.

    OK worse case scenario new motherboard. I might as well upgrade rather than just replace - any suggestions please (not too expensive). Is it easy to replace? I've done a desktop before but not a laptop.
    Thanks

    You can't upgrade laptop motherboards like you can do with replacing desktop motherboards. Laptop motherboards are replaceable but it takes more skill because the laptop has to be entirely torn down...

    I suppose I could live with just using the battery power as it works OK if I could just charge up a new battery but I seem to be able to only charge up my old one which only lasting about 30 mins max. Could this be to do with the motherboard?

    No, the old battery needs replacing too

    The problem is that I can't seem to charge up a replacement battery I have already returned one and on my second replacement that also won't charge. What if I replace the m/b and the battery still won't charge?!

    Unless you can pinpoint the problem to battery/charger I'd say cut your losses. You haven't said whether the new batteries are Acer branded or third party units. That is relevant because you reckon the original battery works even though it's at the end of its life. Battery suppliers will sometimes give a refund.

    A replacement motherboard is going to be expensive and as a DIY project it will take you an awful long time. I'd rather put the money towards a new laptop or tablet. Fixing a laptop is nothing like working on a desktop.

    Laptop motherboards can cost as little as $85 up to around $130 as long as you don't buy replacements from the original manufacturer. EBay is a great source for laptop parts including Dell parts. Most laptop repairs including motherboard take less than 1 hour. Windows Updating takes about 6!

    Replacing the motherboard will solve the battery charging issue. You have already eliminated the AC Charger, and battery itself
