When I press the power button on my laptop it doesnt do anything. When I plug the ac in without the battery the front red light flashes a few times but nothing else. When I put the battery in my laptop  with the ac unplugged, the lights automatically turn on and the fan starts up but this last only a few seconds and then it turns off again. The power indicator on my battery says full charge and when I plug my computer in with the battery installed the light comes on that says it is charging. Please help.

the flashing red light is an error code, how many times is it flashing before the pause?

Try pulling the memory chip and re-seating it. the memory is under a panel on the bottom. should have 2 screws.

The light flashes four times. I tried re-seating the memory and the hard drive. Still nothing. I talked to gateway chat and the guy said it is my motherboard and I need a new one. I dont know if this is true.

Eject your battery, unplug your laptop from the wall.

Plug in Just the power adaptor.

turn on your laptop, what is the result?

Ok, you are having a power issue with the motherboard. I have researched it as a flash pattern common when the voltage is not up to par.

This is not a power supply problem.

on this model there is a voltage regulation/charging circuit that has an issue. Most likely your battery failed, drew too much power and damaged the motherboard (the power circuit) in the process.

I would recommend either find a wizard with electronics to repair the motherboard,
or replace the motherboard (or the laptop)

you can rescue your files by setting your hard disk in a usb enclosure.
this will allow you to get your data  into your new laptop.

I wish I had better news for you buddy.

Good news, your hard disk is most likely intact..

you can also try this :
remove battery and AC - hold power button for 20 sec
now reconnect power and try to boot
if the same, remove all extra devices, also cd and disk drives -  you get a screen when booting?
also if you remove all ram and boot it should beep.
if nothing works, you have a bad mobo or cpu

It flashes before you try to boot the device, It's a power regulation issue with the motherboard.
just plugging it in gives you a flash code.
