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.
STEP 1.
First of all, you can add one memory module into the expansion slot on the bottom of the laptop.

STEP 2.
Remove seven screws pointed with red arrows.
STEP 3.
Carefully lift up the keyboard cover. You’ll have play with the cover in order to release plastic latches.

STEP 4.
Remove four screws securing the keyboard.
STEP 5.
Carefully lift up the keyboard. You don’t have to disconnect the keyboard from the motherboard in order to access the memory expansion slot. Just turn the keyboard over and place it upside down on the palm rest.

STEP 6.
Here’s the memory slot you are looking for.

STEP 7.
Spread latches on both sides of the memory module and remove the old 256MB module and install a new one.
HP Pavilion zv5000 laptops will not take more then 2GB (1GB module in each slot).

Great instructions. Followed the steps exactly and I’m back in business. While I had it apart I cleaned the cooling fans and grills. What a mess!
Thanks

I am up and running much faster, with the new cameras and size of each photo, it used to take a while to browse them, now i can zip thru them with ease. THANKS for the help, it was so easy and simple.

Like other potential upgraders, I spent hours on the internet searching for the location of the second slot. Your illustrations (and thank you for the information)solved the problem. During my installation, I experimented and discovered that the memory system worked with, a 1GB in the first slot, and my remaining 256mb in the “under the key board ” slot, for my HP Pavilion zv5368.

Great guide!
I can confirm this works on my Pavilion zv5000. Very happy now… hopefully I can get a few more years use out of this.
Cheers!

Thank you so much. That was a perfect tutorial. Five minutes and I upgraded from 512MB to 2GB on my aging zv5320 with two sticks I bought off ebay. Will hopefully get a few more years out of it yet!

I did the test (tried both Quick and Advanced) and it was successful. What can I try next?

Tony,
Sounds like that. Apparently your memory is good.
You can download an iso file (CD image) and burn it on a CD. After that you boot your laptop from that CD and run HDD test.
