Here are excellent instructions for upgrading memory on HP Pavilion zv5000 series laptops in seven relatively easy steps. I found links to the disassembly pictures while reading comments on Ask Laptop Freak site and decided to compile them into a guide. Upgrading memory on this laptop could be tricky because one of the memory expansion slots is located under the keyboard. According to HP specifications for zv5000 you can install 2 memory modules up to 1GB each. You should use PC2700 333MHz memory modules.
First of all, you can add one memory module into the expansion slot on the bottom of the laptop.
