Daughter has been complaining about the battery of her laptop she has been using for the past nine months. She cannot use the laptop without being plugged in direct to the power outlet. The battery lasts for five minutes only and the power would shut down at once. If we have laptop warranty including battery, then I could just bring the laptop to the store and ask for replacement. But since we don't have the receipt of warranty, I doubt if we could get a replacement for this.
