My Acer Aspire One came with 1GB of memory, and after installing Windows 7 on it, that 1GB has become inadequate. I bought 2GB of 800MHz DDR2 memory on Newegg for just over $20. This is great value for the money, and improved the overall performance of the netbook significantly. This quick guide will show you how to upgrade the RAM on an Acer Aspire One AO751h, but it might apply to many other laptops as well.
NOTE: Follow this guide at your own risk. I am not responsible for any damages or injuries caused by following these instructions. Your laptop may differ from mine.
1. Buy the correct RAM for your laptop. For my Acer, I bought one 2GB stick of Corsair 800MHz DDR2. Make sure you’re buying laptop memory, not desktop memory. The laptop RAM is obviously a lot smaller.
2. Shut down the laptop. Disconnect your power supply and remove the battery. Ground yourself by touching something metal. I touched my steel computer case. This should dissipate any static electricity that is on you.
3. Get a small phillips screwdriver and unscrew the two screws holding the memory bay on. Then gently pry it off – it is still held in by plastic clips.
4. Remove your RAM by pulling the two tabs on the sides apart, and pulling the RAM up and out. Be gentle.
5. Install the new RAM by pulling the two tabs on the sides apart, and gently inserting the RAM into the slot. Once it starts going in, release the tabs, and when fully inserted the memory module should snap into place.
6. Screw the cover back on and push down on it a bit to get it to clip in. Reinstall your battery and power on the laptop. Right click on “Computer” on your desktop or in your start menu, and click “Properties”. If you see 2GB of memory indicated, the install was a success!
