Having problems with your Gateway 7330GZ Notebook ?
I have a universal ac cord. it works on my sons computer. his is a compac mind is a gateway. the blue light on the adapter will stay on until i plug it to my computer. as soon as that happens the light goes off. i need to know what's going on. i'm getting no power from that adapter. it use to work but, now it does not.
A cell phone charger outputs DC power at a very specific voltage and current, which is why they are made with a connector that will only fit the phone that is expecting that particular voltage and current. A universal ac cord outputs DC power at a (limited) range of voltage with a much wider range of current, which is why it uses the term universal. If you reference the labels on the bottom of the two laptops, I would expect the voltage or current demands of your laptop exceed or are at the highest end of the range that the universal power supply can output, while your son's laptop is well within its comfortable operating range. As the AC power supply has aged, or had been damaged, it can no longer sufficiently supply the draw your laptop is requiring and so it is shutting down to prevent damage to the laptop through a surge. It may be within the realm of possibility that your laptop's power requirement has increased, due to an internal component failure that I cannot think of. It is much more likely that the universal ac cord is not up to outputting what it used to, which you could check with a multimeter is you are so inclined. Hope that helped.

I have a Dell D600 laptop and just put a brand new battery in it. However, the new battery is not charging and the battery light still flashes green 3 times and then flashes red once, then green 3 times, and then red once, on and on. I know that the battery is good because I just purchased it. I have tried several times to reseat the battery, however I can't get the laptop to recognize it and recharge it. What do you recommend?
