  2. Usually factory warranties are good for one year, unless of course, you bought an extended warranty. If the laptop is still within warranty, Acer should cover the costs of a new battery. However, if it is out of warranty, chances are that you'll have to eat the cost of a new battery. How long have you had the laptop?
  3. well, guys, i think the issue is the battery "memory effect", I have had a really similar problem with my xps 1530 battery. Overnight the battery stopped charging. I find it hard to believe its just died suddenly. when the laptop batteries were not full discharged(means the batteries not show 0% power), and then were charged, they will "remember" the latest power level as the full 100% power level, when you run them down and recharge them, they will show you 100% full charge as their "memory",but not really full charge.

    so, you can over discharge them and than over charge the laptop batteries for 4-5 hours, the "memory effect" will disappear. If the problem is still exist,you should buy a new one and hope it can help you.


  4. I had 2010 Acer Aspire 4740(year 2010), battery charging upro 26% only.
  5. Hi :)

    Modern Lithium Ion batteries CANNOT get memory effect.....

    And the WORST thing you can do to one is to deep cycle will KILL it...

    All the best Brett :)
