Re: Replacing the motherboard
Taking Gateway laptops is an easy endeavor. Here is a link to a disassemble of a 3500 series . Basically they all come apart the same.
Hope this helps. Just take your time and remember what screw goes where.

Usually these beeps are signs of hardware failing inside the unit. Does everything load correctly? Start with removing one stick of RAM at a time to see if the beeps stop, if they continue it may be a bad motherboard.
Generally the power is soldered directly on to the motherboard on a laptop. So for the most part replacing it either means, finding an identical power supply and being really good at soldering, or replacing the motherboard. Either way if you are not very familiar with taking laptops apart, and computers in general, I would recommend you take it to someone who repairs them for a living.
If the laptop is still relatively new....check with Gateway to see if it's under warranty. If it is, they should fix it or replace it for free. If it is beyond warranty, you may find it comes out more expensive to fix, than just buying a new laptop.
Replacing a case is one of the most involved repairs on a laptop because you are basically disassembling the entire thing. You will want to be very careful as there are plastic clips you can break, start by removing the harddrive, the memory door / memory and battery. Take all the screws from the bottom (tape them down on a piece of paper to remember their position, you can write down labels from where they came from. when this is done you should be able to remove the cd drive and lift the keyboard. Remove all the screws from under the keyboard, and remove the ribbon connectors. The upper and lower plastic should snap apart with a little tension. After your inside you can remove the rest of the screws to take out the motherboard. These instructions are generic to most laptops, your should be fairly similar.
it may need to be left on charge for a while...
when u first boot by pressing power wait for a minute or so and press and hold power button til shut down then try reboot..also try boot from disk....need to distinguish whether motherboard or software issue.
