First off let me say this. To my knowledge from what I have seen and read, outside of some tech sites, people who know better, and people like me who took a chance and did it anyway, you will not find this information anywhere. Why is beyond me since it’s quite simple. HP’s own website along with memory upgrade sites like Crucial (not picking on them mind you) state that the HP Pavilion dv9260′s memory (RAM) is maxed out. I believe this is because they measure upgrade ability by the amount of memory card slots a given PC or laptop have versus how many are in use (occupied) out of the box. It seems that they don’t always take into account that a 1GB chip can be replaced with a 2GB chip. So unless they change how they measure upgrade ability these sites are useless except for picking out the type of RAM you want and can use. Okay, enough on that, let’s get down to it. Here’s what I did to upgrade my laptop. First, go to HP’s website and get all the updated driver’s and install them. This is should allow SP1 to install with no problems. Second, if you haven’t already, download Vista SP1 and install it. This is the only way your laptop will display the full 4GB on the System Information screen. Once you have done this you can then install the 4GB of RAM. Told you it was simple. Now you should be the proud owner of a dv9260 with 4GB of RAM moving at a much better pace than before. This is the amount of RAM an “Entertainment PC” should come with.
- Install all the latest HP Pavilion dv9260 drivers (reboot after each install just to be safe).
- Install Windows Vista SP1.
- Reboot (auto reboot may kick in again, once, twice, thrice, it’s normal).
- Disconnect power including the battery
- Install 4GB of RAM.
- Reconnect power and turn it on.
Now, if you already have 4GB installed prior to installing Vista SP1, the BIOS will read the full 4GB with no problem. Check and you’ll see what I’m talking about. But, Vista won’t and will only display about 3GB (3072MB) of the total amount. Don’t worry it does read the 4GB there but, it will only display the available amount. I’ve seen it first hand with my own laptop so I’m not just saying this.
Why are we installing all these drivers from HP first? Well, since you want Vista to display all the installed RAM you need Vista SP1. From what I understand about SP1, it will only install on PCs that it sees has all the latest certified drivers installed. How true this is, I don’t know because I didn’t try installing it prior to updating my laptop and I like to keep it updated and working smooth. Remember to reboot after each install so you don’t run into any problems. The worst part is that this is tedious and takes time but the reward is worth it. Pick a day you want to be a lazy couch potatoe and do this.
