I have a couple of Gateway laptops (MA3 and MA7) that won't power up or charge. I've stripe them down removing all periphables and even removed the motherboard from case. I've checked the power jack and power supplies with volt meter and they test good. Both computers are dead with no response when the power button is pressed. There are a number of threads out there that describe this same problem with Gateway laptops, however, no resolution. Could it possibly be the CMOS battery? Has any found a solution to this problem?
