I have a gateway M-1629. The 3-prong power cord that came with the laptop was working when I FIRST got it. After a couple months it would not CHARGE the laptop. I brought another charger with multiple adapters with one for a gateway laptop and that worked until just recently. >:(vThere was an extra adapter that fits into my laptop and keeps it on but it doesn't charge. The battery's life has also shortened from 2.5hrs of power to a small 39mins on a full charge. Is the problem with the battery, the cords, or the power connector in the laptop?POSSIBLY bad charger has damaged the battery.

Check to SEE if there is a Batteries Plus store nearby. They have the equipment to check the battery for various loads and they can do the charger as well. Ok thanks. But sadly, a Batteries plus is nowhere me. How old is the laptop? In my experience laptop batteries have a lifespan of about 5 years under average use. As they get older they will loose CAPACITY.

You can get a new battery from Gateway but they are expensive so try to get the old one tested first as said. Some normal electronic component stores may test it too.

If you do get a new battery I would recommend getting a genuine gateway charger too - You could break your brand new battery by using a slightly incompatable charger!

Cameron Graythanks for the advice and the laptop isn't even a year old yet.Quote
