<li><p>How hard is it to install RAM? I was just looking over some Lenovo computers and they charge ridiculous for the RAM when you can get it cheaper at other places, but it wouldn’t come pre-installed. I was just wondering if it’s worth the money for that expensive RAM.</p></li>
<li><p>What’s the difference between LED or CCFL screens?</p></li>
<li><p>I’ve heard that anything after 4 GBs of RAM is worthless. Is there any truth to this?</p></li>
</ol>
<p>1) It depends on the computer, but it shouldn’t be too hard and you could likely find a guide on how to online</p>
<p>2) LED screens use less energy and are brighter. Also look at the different resolutions offered in each type of screen.</p>
<p>3) That is true if you have a 32 bit operating system since it cannot address more than 3.5 GB of RAM. In a 64 bit operating system that isn’t true at all, they can address far more than 4 GB of RAM and it would not be wasted.</p>

<li><p>The best answer is “it depends on the computer,” but for the most part, RAM is easy to install. In the case of my Lenovo ThinkPad R61, I just had to remove four screws on the backside and then take off keyboard rest. The RAM is easily removed and replaced. I definitely recommend doing it yourself as it doesn’t void your warranty and improves your handiwork skills.</p></li>
<li><p>LED-backlit screens consume less power. There are other reasons why they are better than CCFL-backlit screens, but I don’t know them.</p></li>
<li><p>It depends on the person. If you plan to be doing some serious graphics manipulation, then 4GB may not be enough! If all you do is use Firefox and Office, then anything above 4GB is overkill.</p></li>

<p>Do you add RAM, or do you replace RAM? Say I get a computer with 1 ram. Should I buy 4 RAM or 3 RAM to add to the 1 already there? Also, could you guys reply to the other thread I have here as well? Thanks.</p>
<p>My Lenovo ThinkPad R61 came with one stick of 1GB DDR2-667 RAM. When I wanted to upgrade to 2GB of RAM, I simply bought another stick and added it. My suitemate’s laptop, on the other hand, came with two sticks of 512MB DDR2-533 RAM. When he wanted to upgrade to 2GB of RAM, he had to buy two sticks of 1GB DDR2-533 RAM to replace his existing pair. Likewise, when I wanted to upgrade to 4GB of RAM, I had to buy two sticks of 2GB DDR2-667 RAM to replace my existing pair.</p>
<p>I think it should say whe yu order the configuration it comes in. </p>
<p>yah when you are ordering it on the lenovo website it syas eiher 1 DIMM or 2 DIMM next to howmc memory you are getting. 1 DIMM means it is 1 stick of memory and I believe there are 2 memory channels.</p>
