First You Need Some Stuff:
1. Mini Screw Driver #0 Size
2. Static Bracelet
The right size mini screw driver is important, you do not want to strip these screws. A couple different sizes will end up working fine, use common sense, get the right tool for the job. A static bracelet is really important if you plan on opening up your computer and doing any work. This makes sure the static electrically stored in body doesn't fry any of your computer components. They're cheap, they work and they're less than five bucks. BUY ONE! Please use common sense,don't force anything in, buy the bracelet, unplug your laptop, take out the battery and take your time.
Put on your static bracelet, unplug your computer. Turn it over.
It should look like this:
Now take out your battery out and unscrew the RAM cover.
You should now see this:
*Note I was stupid and forgot to unplug my battery when I took this picture. You don't need electricity running through your 1501 while you do this. Turn of your 1501, take out the battery and unplug it.
Now take your RAM and look for the notch by the pins (the shiny metal part) and insert it at a 30 degree angle into the Empty DIM slot, lining up the notches. Push firmly and then push the RAM stick down locking it into place.
Replace the cover, put in your battery. Flip over your computer and enjoy.
