Having problems with your Gateway 7210GX Notebook ?

I have just got a new charger for my gateway and when i plug it in i hear a snap and cracking noise


Answers :

Check the Amper of you laptop and the charger they must be equal.if that was turn on your laptop if it work properly and the battery charge completely there is not any problem.
\015\012Anyway its better that you test with another charger and if there not any sound with that ,change your charger.
\015\012that sound usally produced for overused of amperage for the laptop .
Are you sure the charger is the correct specs for your model? Check the label on the laptop and on the charger to be sure they match. The voltage and amps should be the same. Most importantly check the polarity which will be a graphic that looks something like this:

o)--->+

What that is telling you is if the center of the plug is positive or negative. The only thing that matters is that the pictures are the same. If you switch your polarity you will almost always blow out your power supply on the system board. Does the laptop power on or has it not worked since you heard the noise?

If it has not powers on odds are the specs are wrong on your charger and you might have damaged the laptop. If the laptop still works then it is possible the charger is providing too much power or malfunctioning. A laptop will work with a more powerful charger sometimes, but it is never recommended as it will create more heat and reduce the life time of the laptop system board.

Emachine beeps Hey, we just got a new emachine and we have the same problem! We got it mid/end of April but were in the process of moving so it stayed in the box till about a week ago.

Fried something? my computer, a compaq evo n600c notebook, will not turn on. I plug the charger in, and the green "on" light turns on for a half a second, then nothing. I can hear popping from the dc socket on the computer, so i'm guessing that's not good. the charger should be supplying 18.5 volts, and it's supplying 19, should that .5 volts be causing this? I got a new motherboard for like $50 and the same thing happened so i'm guessing it's not with the motherboard.


A half volt will not make any difference. Sounds like the power supply is malfunctioning. Start by trying a different one. Keep in mind that you may have fried the new motherboard by using a faulty power supply. Popping sounds indicate a ... HP Compaq Evo Notebook N600c

Beeping Noise My laptop's battery is shot, so I MUST run on AC power, plugged into an electrical outlet. The AC power cord is somewhat frayed, and sometimes shorts out.

It is not very loud,but it occurs about every 3 seconds. Every time it beeps, the keyboard will not type the letters that I pressed during the
