1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. Make sure the DC jack is not loose or broken. A loose DC jack will need to be re-soldered. A broken one will need to be replaced.
4. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
5. The power button could be bad
6. The motherboard could be defective & needs to be replaced.

My nv79 notebook charges up my battery to 100% the charge light turns blue and after 1 minute cuts off and requires restarting to start charging again


Try removing your battery and power on your computer with your power cord only. If you have no problem with the power cord alone, then you need to replace the battery.

I hope this helps!

I have a gateway nv79 and it won't turn on. The


Step 1:
If your laptop charger seems broken, it's most likely because the battery will not charge. You plug in the cord, the lights come on, but the charging light doesn't change or blinks repeatedly. When you remove the power cord, the laptop shuts off instantly due to the depleted battery. There's more than one cause for this, and it's not always a broken charger.

Check the connection between the charger and the laptop. It should fit firmly in the DC jack without wiggling. If it is loose, use electrical tape to hold it in place so the charger can receive power. This is a temporary fix, however, because a faulty connection can create sparks and cause a fire or injury. A loose connection will just get worse over time, so have it sent to a DC jack specialist as soon as possible. Turn off the laptop and flip it upside down. Locate the latch that secures the battery and slide open. The battery should pop out; give it a tug if it doesn't. Apply a small amount of rubbing alcohol (Methylated Spirits)to the tip of a cotton swab and use it to clean the battery's connectors. Dirt can build up and interfere with the connection, giving the appearance of a broken charger. Let the alcohol dry completely and re-insert the battery. Slide the latch to secure it and plug in the power cord to test it. See if the laptop powers on with the charger only and battery removed. If it does, the battery is the likely culprit and should be replaced. If the charger is truly broken, the only thing to do is to replace it or the power cord attached to it. Look on the bottom and write down the part number. Call the laptop manufacturer for a replacement charger or search for the part number on eBay. If you purchase from anyone other than the original manufacturer, ask for genuine parts to reduce the possibility of problems. Troubleshoot Mag Safe adaptors

When I turn on my laptop the power lights up and shuts off after a few seconds


either a bad battery, or charge port. even if the battery was fully charged it will still keep the light on, try this. plug it in, and power it on, then remove the battery completly, the computer should stay on, as its running off the plug power cord. if this port is a bad one the pc will shut off immeadatly. and if it stays running then it will be the battery.

Seems to be a problem of not enough power.

2 Let it sit for 1-2 minutes.
3 Press and hold down the power button for 30 seconds.
4 Reconnect battery and charger and try to start by pressing the power button.

After shutdown of gateway laptop blue power button stays lit.....


Hi this sounds like your computer is in hibernation mode as opposed to shut down mode. Could you check and see as if running Vista many people assume that clicking on the brown power type selection under start that they are shutting down where as this actually only hibernation mode and clicking on the little arrow to the right of this and selecting shutdown is the way to go.
I hope this helps
