1. The battery is over 1 year old. This is rough on those the didn't notice the battery supplied with most laptops are rated for 300 cycles. Yes most of us get more than a year.
2. The laptop jack needs repair. This is such a common problem that a small industry specializing in this repair has been created. Google LAPTOP JACK REPAIR to see this small industry.
I have a Gateway laptop Model MX6440. My battery Icon on the lower right flashes on and of, the screen changes brightness at the same rate. I open the battery application via the Icon and I see that it is switching from AC to Battery at the same rate. I first thought it was the battery, bought a new one but it still does it with the new battery. I know my power supply is working and putting out 19V (checked with meter). What is the problem and how do I fix it.
Thank you ahead of time.
