Either the electronics in the charger or the battery have failed. Or there is something wrong with your power jack.

It sounds like you either have a dead mother board or a bad power inlet. Did the machine work with the new battery while it was charged? If so, then the battery connector was good and the inlet was bad. If not, your motherboard could be dead. I've also seen where a bad battery connector would syphon off enough power to not power on the machine or charge the battery.

Make sure the small cable from the switch to the mother board hasn't come loose. It comes loose fairly easily when reinstalling the cooling fan plenum. Its happened to me twice. Its even possible to plug it in the wrong place. Doesn't hurt to double check.

You could well be correct but just to make sure.

You need to beg, borrow or steal another known good power supply/charger unit and see if that works. You see if yours in faulty, its not charging the battery or supplying power to the laptop.

If nothing glows after that it could be the charger circuit on *********** board or just the power connector on the motherboard .

Hi
I presume you checked the DC power supply. Don't use a generic power supply on this model, because that will cause alot of different symptoms. I use the exact same model on service calls. A further way to test the mother board is to remove the CPU and memory. Carefully provide power and look for lights. If none, my next step would be to refloat the video chip. This requires special equipment. A replacement mother board without processor on eBay is $49.00 so it might be time to consider that. Good luck

Hi,

Yes this indicates that your video card has gone bad and would need to be replaced. Sadly, the whole mother board would have to be replaced. Hope I helped

Go to ebay,if it's not there....you may be out of luck. Did you try gateway? I didn't look it up but they may still service that board.

first you need to check that is the light on the power cord on the adapter is coming if yes then it is supplying the current to teh machine and it is not charging the battery then mother board needs to be replaced if the light on the adapter is not coming up then need to chage the adapter .

Gateway was working good went upstairs came back NOTHING BLACK SCREEN....

My gateway screen was constently black every time I powered on nothing no bios, nostart up no warning..The board has indicating lights to follow the start up power light on, battery light on, then the disk drive....but thats it normaly the harddrive reader light comes on but nothing.... So detached every component and tested individually..... come to find out one of my 2 ram slots is damaged not the chips...this could be your problem..try

Try resetting the bios by moving the cmos jumper to the clear position on the motherbaord for a minute or so.

Hope this helps?
